The API calculates fees, fetches live exchange rates (Nabla DEX, price providers), applies the dynamic pricing adjustment, and returns a `QuoteResponse` including the expected output amount, fee breakdown, and a quote ID. +2. **Expiry** — Quotes expire **10 minutes** after creation (hardcoded in `QuoteTicket.create()` and the model default: `new Date(Date.now() + 10 * 60 * 1000)`). After expiry, the quote cannot be used to start a ramp. Note: this is a separate timeout from `discountStateTimeoutMinutes` (see Dynamic Pricing below). +3. **Binding** — When a ramp is registered (`POST /v1/ramp/register`), it binds to a specific quote ID. The quote's amounts become the committed values for the ramp. +4. **Consumption** — A quote can only be bound to one ramp. Once consumed, it cannot be reused. + +### Dynamic Pricing System ("Discount Engine") + +The platform uses a per-partner dynamic pricing mechanism to adjust the offered rate based on partner quoting behavior.

Converted to a decimal: `0.3 / 10000 = 0.00003`. +- `discountStateTimeoutMinutes` (config, default `10`) — The inactivity window. If a partner's last quote is **older** than this timeout, the system considers it "inactive" and adjusts the rate on the next quote. +- `targetDiscount` (per-partner, DB) — The partner's base discount rate (from the `partners` table). +- `minDynamicDifference` (per-partner, DB) — Lower bound for the dynamic adjustment (can be negative). +- `maxDynamicDifference` (per-partner, DB) — Upper bound for the dynamic adjustment. + +**How it works:** + +The system maintains an **in-memory** `Map` called `partnerDiscountState`. + +1. **On each quote request** (`getAdjustedDifference`): + - If no state exists for the partner → initialize with `difference = 0`, return `0`. + - If the last quote was **within** the timeout window → return the current `difference` unchanged. + - If the last quote was **outside** the timeout window (partner was quoting but not converting) → **increase** `difference` by `deltaD` (= `deltaDBasisPoints / 10000`), clamped at `maxDynamicDifference`.

The expiry is checked via `quote.expiresAt < new Date()` at registration time. Exchange rates change; stale quotes expose the platform to unfavorable rates. +2. **Each quote MUST be consumable exactly once** — After a quote is bound to a ramp, it MUST NOT be reusable for another ramp. This prevents a single favorable quote from being exploited multiple times. +3. **Quote amounts MUST be immutable after creation** — Once a quote is stored, its `inputAmount`, `outputAmount`, fee breakdown, and exchange rate MUST NOT be modifiable. The ramp uses these exact values. +4. **The quoted output amount MUST be the guaranteed minimum the user receives** — The platform subsidizes any shortfall between the actual swap result and the quoted amount (up to the subsidy cap). The user MUST NOT receive less than the quoted output (after fees). +5. **Fee calculations MUST be deterministic for the same inputs** — Given the same input amount, currencies, ramp direction, and fee configuration, the quote MUST produce the same fee breakdown. Non-deterministic fees create audit and reconciliation gaps. Note: the dynamic pricing adjustment (`difference`) adds intentional variability to the *rate*, not the *fees*. +6. **Quote validation MUST occur at ramp registration time** — When binding a quote to a ramp, the API MUST verify: quote exists, quote is not expired, quote is not already consumed, and the requesting user/partner is authorized to use it. +7. **Dynamic pricing `difference` MUST be clamped to partner bounds** — The `difference` value must never exceed `maxDynamicDifference` or fall below `minDynamicDifference`. Both bounds are enforced in `getAdjustedDifference` and `handleQuoteConsumptionForDiscountState`. +8. **Dynamic pricing state MUST NOT be externally modifiable** — The `partnerDiscountState` Map is in-memory and module-private. No API endpoint should expose or allow modification of discount state. +9. **Exchange rates MUST be sourced from authoritative on-chain data** — Swap rates should come from the actual DEX (Nabla) or routing protocol (Squid), not from stale caches or third-party price feeds that could be manipulated. +10. **Subsidy MUST only be applied when `targetDiscount > 0`** — If a partner has no target discount configured, the subsidy amount is always `0`, regardless of the shortfall. + +## Threat Vectors & Mitigations + +| Threat | Attack Scenario | Mitigation | +|---|---|---| +| **Stale quote exploitation** | Attacker creates a quote when rates are favorable, waits for rates to move against the platform, then registers a ramp at the old rate | Quote expiry (10 minutes hardcoded); platform subsidizes the difference but bounds it via subsidy cap (`maxSubsidy`) | +| **Quote replay** | Attacker uses the same favorable quote ID for multiple ramps | One-time consumption: quote status is set to `"consumed"` on ramp registration; second attempt is rejected (`quote.status !== "pending"`) | +| **Quote manipulation** | Attacker modifies quote amounts in transit or in database | Quotes stored server-side; amounts calculated server-side from authoritative sources; client cannot override amounts | +| **Price oracle manipulation** | Attacker manipulates the DEX price before requesting a quote to get an artificially favorable rate | Use TWAP or multi-source pricing; bound acceptable deviation from reference rates; monitor for unusual quote patterns | +| **Dynamic pricing farming** | Attacker rapidly requests quotes without consuming them to push `difference` toward `maxDynamicDifference`, then consumes at the best possible rate | Each quote request within the timeout window does NOT change the difference — only quotes **after** the timeout increase it.

Long-running ramps with many retries could accumulate entries, but each entry is just an integer. | +| **Phase skip attack** | Attacker manipulates DB to skip phases (e.g., jump from `initial` to `complete`) | Phase transitions are controlled by handler return values, not external input. However, if an attacker has DB access, they could modify `currentPhase` directly — no DB-level constraints prevent invalid transitions. | +| **Unrecoverable error without state transition** | A non-PhaseError (unexpected exception) propagates up without transitioning to `failed` | The catch block re-throws non-PhaseErrors after logging.

On retry, it selects a different RPC node. When all RPCs are exhausted, it throws `RecoverablePhaseError` with a 30-minute wait to allow chain recovery. +2. **Moonbeam receiver contract `executeXCM` MUST only be callable by the executor key** — `moonbeam-to-pendulum-handler.ts` uses `MOONBEAM_EXECUTOR_PRIVATE_KEY` to call the receiver contract. This key is a server-side secret; the call cannot be forged by clients. +3. **Moonbeam receiver contract flow MUST verify hash registration before XCM** — The handler first waits for `getHashRegistered()` to return `true` for the pending nonce, confirming the split receiver contract has recorded the expected parameters. Only then does it call `executeXCM`. +4. **Pendulum→Moonbeam XCM MUST use 3-tier recovery** — (a) If transaction hash is stored, check Pendulum for success. (b) If tokens already left Pendulum, wait for Moonbeam arrival. (c) Only submit fresh if neither condition is met. This prevents double-XCM. +5. **Pendulum→Moonbeam MUST verify Moonbeam arrival with a 2-minute timeout** — After XCM submission, the handler polls the Moonbeam ephemeral balance. Timeout throws a recoverable error for retry. +6. **Hydration→AssetHub XCM MUST NOT wait for finalization** — `submitExtrinsic` is called with `waitForFinalization=false` because finalization does not work on Hydration. The handler proceeds after inclusion. **This means the transfer can theoretically be reverted by a chain reorganization.** +7. **Hydration→AssetHub MUST use nonce-based re-execution detection** — If `currentNonce > executeNonce`, the handler skips re-submission and transitions directly to `complete`. +8. **Hydration swap MUST use a presigned transaction** — The swap extrinsic is presigned at ramp creation and stored. The handler decodes and submits it. Server cannot modify swap parameters at execution time. +9. **All XCM handlers MUST treat already-executed transfers as success, not error** — Re-execution detection (nonce checks, balance checks, hash checks) must transition forward, never re-submit. +10. **Moonbeam→Pendulum handler retry loop MUST be bounded** — The handler retries `executeXCM` up to 5 attempts with 20-second delays. After exhaustion, the error propagates to the phase processor for higher-level retry. + +## Threat Vectors & Mitigations + +| Threat | Mitigation | +|---|---| +| **Double XCM submission** — Crash after XCM sent but before phase transition causes re-execution on retry | Multi-tier recovery in all handlers: check transaction hash, check source balance depletion, check destination balance arrival before re-submitting. | +| **RPC node failure during Moonbeam→Pendulum** — Single RPC failure blocks the transfer | RPC shuffling: each retry uses a different RPC node. After all RPCs exhausted, 30-minute cooldown allows infrastructure recovery. | +| **Moonbeam receiver contract called with wrong parameters** — Executor key misused to call `executeXCM` with attacker-controlled parameters | The handler reads parameters from the stored ramp state (set at creation time). The executor key is server-side only. An attacker would need server compromise to manipulate the call. | +| **Hydration chain reorganization after non-finalized XCM** — Transfer included but reverted due to chain reorg | **KNOWN RISK**: No mitigation. Finalization is explicitly skipped ("doesn't work on Hydration"). A reorg could result in the ramp transitioning to `complete` while the XCM transfer was actually reverted. Probability depends on Hydration's block finality characteristics. | +| **Moonbeam→Pendulum blind retry loop** — 5 attempts × 20s delay = 100s of repeated contract calls that may all fail | After 5 attempts, the error propagates to the phase processor, which has its own retry budget (8 retries). Total retry surface is 5 × 8 = 40 attempts across all phase processor cycles. | +| **Balance polling false positive** — Token balance on destination matches expected amount due to unrelated deposit | Ephemeral accounts are single-use, so unrelated deposits are unlikely. However, if the ephemeral receives tokens from another source during the same ramp, the balance check cannot distinguish them. | +| **Nonce desync across chains** — Nonce used for re-execution detection is read from a stale state | Nonces are read from on-chain state at execution time (`getTransactionCount` / API queries), not from cached values. | +| **`MOONBEAM_EXECUTOR_PRIVATE_KEY` compromise** — Attacker can call `executeXCM` on the receiver contract | Receiver contract should validate that the caller is the authorized executor.

New fields added to controllers may not get corresponding validators. | +| **Mass assignment** — Extra fields in the request body are passed to database operations | Validators check for expected fields but don't strip unknown fields. If a controller passes `req.body` directly to a database query (e.g., Sequelize `create(req.body)`), extra fields could set unintended columns. | +| **Error response information leak** — The `errors` array in error responses reveals internal validation logic or database field names | Error handler wraps errors in `APIError`. The `errors` array content depends on what validators put there. Validator messages reference field names from the API schema, not necessarily database internals, but should be audited. | +| **Staging CORS origin in production** — `staging--pendulum-pay.netlify.app` is in the CORS whitelist | If the staging site has an XSS vulnerability, an attacker could use it to make authenticated cross-origin requests to the production API. Staging origins should ideally be removed from production CORS config. | +| **No per-endpoint rate limiting** — Sensitive endpoints (ramp creation, admin operations) have the same rate limit as public read endpoints | An attacker can create 100 ramps per minute per IP.

No output verification against expected amounts. | +| **Hardcoded business account address** — `brlaBusinessAccountAddress` default is wrong or points to an attacker-controlled address | Funds would be sent to the wrong address. The address should be verified against BRLA's official documentation and set via environment variable, not hardcoded. | +| **5% slippage exploitation** — An attacker manipulates the Nabla DEX pool to extract up to 5% per rebalance via sandwich attacks | 5% slippage tolerance is generous.

There is no way to do zero-downtime rotation. | +| **Lateral movement from price provider keys** — Compromise of AlchemyPay/Transak/MoonPay keys | Limited blast radius — these keys access price data, not funds. However, an attacker could manipulate prices shown to users (if the provider API allows it) or access transaction data. | +| **Google Sheets credentials** — Access to fee logging spreadsheet | Could expose fee data and ramp metadata. Could manipulate fee records. Lower severity than financial keys but still a data leak. | +| **`SUPABASE_SERVICE_KEY` used for all database operations** — No principle of least privilege | The service key bypasses all RLS. If any code path leaks this key, the attacker has unrestricted database access.

Intentional: userId is attached if available but not required. +- `POST /v1/quotes/` and `POST /v1/quotes/best` — quote creation is public by design (SDK/frontend creates quotes before auth). Intentional. +- `POST /v1/brla/createSubaccount`, `POST /v1/brla/getUploadUrls`, `POST /v1/brla/newKyc`, `POST /v1/brla/kyb/new-level-1/web-sdk`, `POST /v1/brla/kyc/record-attempt` — BRLA KYC operations where userId is optional for tracking. + +All these are reasonable uses of `optionalAuth`. However, several BRLA KYC endpoints arguably should use `requireAuth` since they create or modify user-specific resources (subaccounts, KYC records). This is a design question, not a strict violation. + +--- + +#### 3. `[FAIL]` `SupabaseAuthService.verifyToken()` uses the service role key, not the anon key + +**NEW FINDING — F-018.** + +At `supabase.service.ts:147`: +```typescript +const { data, error } = await supabase.auth.getUser(accessToken); +``` + +This uses the `supabase` client (created with `SUPABASE_ANON_KEY` at `config/supabase.ts:11`), **NOT** `supabaseAdmin` (created with `SUPABASE_SERVICE_KEY` at `config/supabase.ts:4`). + +**Analysis:** `supabase.auth.getUser(accessToken)` sends the access token to the Supabase REST API endpoint `/auth/v1/user`. The Supabase server verifies the JWT server-side regardless of which client key was used — the anon key identifies the project, while the access token itself is what gets verified. So this is **functionally equivalent** to using the admin client for token verification. + +However, the spec explicitly states "MUST use `SUPABASE_SERVICE_KEY`" and there's a subtle difference: with the anon key client, if Supabase's Row Level Security (RLS) policies interact with the verification call, the anon key's permissions apply. With the service role key, RLS is bypassed. For a pure `getUser()` call this doesn't matter, but it's a deviation from the spec's stated requirement. + +**Severity: 🔵 LOW** — Functionally correct (server-side verification happens regardless), but deviates from spec and best practice. Using `supabaseAdmin.auth.getUser(accessToken)` would be more explicit and immune to any future Supabase auth API behavior changes. + +--- + +#### 4. `[PASS]` The `Bearer ` prefix check uses `startsWith("Bearer ")` with the trailing space + +Confirmed at `supabaseAuth.ts:20`: +```typescript +if (!authHeader?.startsWith("Bearer ")) { +``` + +The trailing space after "Bearer" is present.

For a `Bearer eyJhbG...` header, this reveals the scheme and JWT header prefix but not the signature or payload. Acceptable truncation. ✅ + +--- + +#### 8. `[FAIL]` `SUPABASE_URL`, `SUPABASE_ANON_KEY`, and `SUPABASE_SERVICE_KEY` are validated at startup + +**NEW FINDING — F-019.** + +At `config/vars.ts:115-118`: +```typescript +supabase: { + anonKey: process.env.SUPABASE_ANON_KEY || "", + serviceRoleKey: process.env.SUPABASE_SERVICE_KEY || "", + url: process.env.SUPABASE_URL || "" +} +``` + +All three default to empty string `""`. There is **no startup validation** anywhere in the codebase that checks these values are non-empty. + +At `config/supabase.ts:4,11`: +```typescript +export const supabaseAdmin = createClient(config.supabase.url, config.supabase.serviceRoleKey, ...); +export const supabase = createClient(config.supabase.url, config.supabase.anonKey); +``` + +If these are empty strings, `createClient` will create a client pointing to an empty URL with an empty key. All auth verification calls will fail (network error), and `requireAuth` will correctly reject requests (fail closed). However, the service will appear to start normally — auth just silently stops working. + +**Severity: 🟡 MEDIUM** — The service starts and serves requests, but all authenticated endpoints silently become 401-only. No health check or startup log would indicate the misconfiguration. + +**Fix:** Add startup validation that terminates the process if any of the three Supabase config values are empty. + +--- + +#### 9. `[PASS]` Token expiry is enforced by the verification call + +`supabase.auth.getUser(accessToken)` sends the token to Supabase's server, which verifies both the signature and the expiration claim (`exp`). Expired tokens return an error, which results in `{ valid: false }` at `supabase.service.ts:149-151`. ✅ + +**Note:** This relies on Supabase's server-side behavior. If the anon-key client were somehow configured for local-only verification (it's not in the current Supabase JS SDK), expiry enforcement would depend on the JWT library. Currently safe. + +--- + +#### 10. `[PARTIAL]` No endpoint that should require auth is using `optionalAuth` as a shortcut + +As noted in checklist item #2, the `optionalAuth` usage on BRLA KYC endpoints (`createSubaccount`, `getUploadUrls`, `newKyc`, `kyb/new-level-1/web-sdk`, `kyc/record-attempt`) is questionable. These endpoints create user-specific resources (BRLA subaccounts, KYC records). If a user is not authenticated, these operations would proceed without associating the user, which could be intentional (KYC flow before login) or an oversight. + +The ramp `/register` endpoint with `optionalAuth` is more defensible — the registration may occur before the user is fully authenticated. + +**Not a standalone finding** — this is a design question that should be evaluated alongside the broader F-013 discussion. + +--- + +### Supabase OTP Audit Summary + +| # | Checklist Item | Result | +|---|---|---| +| 1 | `requireAuth` on all protected endpoints | 🔴 **FAIL** — Cross-ref F-013 | +| 2 | `optionalAuth` only where unauthenticated access intended | ✅ PASS | +| 3 | `verifyToken()` uses service role key | 🔵 **FAIL** — Uses anon key client (F-018) | +| 4 | `Bearer ` prefix check correct | ✅ PASS | +| 5 | `req.userId` only set by auth middleware | ✅ PASS | +| 6 | Error responses leak no token/internal data | ✅ PASS | +| 7 | Token truncation in logs | ✅ PASS | +| 8 | Supabase config validated at startup | 🟡 **FAIL** — Empty defaults, no validation (F-019) | +| 9 | Token expiry enforced | ✅ PASS | +| 10 | No `optionalAuth` misuse | 🟡 PARTIAL — BRLA KYC endpoints questionable | + +### New Findings from Supabase OTP Audit + +| ID | Severity | Summary | +|---|---|---| +| **F-018** | 🔵 LOW | `verifyToken()` uses anon-key Supabase client instead of service-role client — functionally correct but deviates from spec | +| **F-019** | 🟡 MEDIUM | No startup validation for Supabase config — empty `SUPABASE_URL`, `SUPABASE_ANON_KEY`, `SUPABASE_SERVICE_KEY` default to `""`, service starts but auth silently fails | + +--- + +## 01 — Auth / API Keys + +### Checklist Results + +#### 1. `[PARTIAL]` All endpoints requiring partner auth use `apiKeyAuth({ required: true })` or `enforcePartnerAuth()` + +`apiKeyAuth()` is applied on quote routes (`quote.route.ts:48,107`) with `{ required: false }` — meaning it validates the key if present but doesn't require it.

This is covered under F-013. + +--- + +#### 2. `[PASS]` `safeCompare()` is the only comparison used — no `===` or `==` + +At `adminAuth.ts:63`: +```typescript +const isValid = safeCompare(token, config.adminSecret); +``` + +No `===` or `==` comparison of the token anywhere in the file. Only `safeCompare` is used. ✅ + +--- + +#### 3. `[EXISTING FINDING]` `safeCompare()` leaks secret length + +Already tracked as **F-010**. At `adminAuth.ts:97-98`: +```typescript +if (a.length !== b.length) { + return false; +} +``` + +Returns early on length mismatch. An attacker can probe with different-length tokens to determine the exact length of `ADMIN_SECRET` via timing analysis. The subsequent XOR loop (lines 101-104) is constant-time for equal-length strings. + +--- + +#### 4. `[PARTIAL]` `config.adminSecret` is validated at startup + +The middleware checks at runtime (line 49): +```typescript +if (!config.adminSecret) { +``` + +This correctly blocks requests when `adminSecret` is empty. However, there is **no startup validation** — the service starts normally with an empty `adminSecret`. The check only fires when an admin request is made, returning 500 at that point. + +At `config/vars.ts:67`: +```typescript +adminSecret: process.env.ADMIN_SECRET || "" +``` + +Defaults to empty string. No startup guard. + +**Not a new finding** — this is analogous to F-019 (Supabase config). The runtime check (returning 500) is sufficient to prevent unauthorized access, but the delayed failure mode is suboptimal. + +--- + +#### 5. `[PASS]` No admin endpoint accepts Supabase auth or API key auth as fallback + +`admin/partner-api-keys.route.ts` imports only `adminAuth` and applies it via `router.use()`. No other auth middleware is imported or applied. Admin auth is the sole auth layer. ✅ + +--- + +#### 6. `[PASS]` Admin endpoints are not reachable from the public frontend + +Admin endpoints are under `/v1/admin/...`. The CORS whitelist (`express.ts:31-38`) allows: +- `app.vortexfinance.co` (production frontend) +- `metrics.vortexfinance.co` (metrics dashboard) +- `staging--pendulum-pay.netlify.app` (staging) + +All origins are allowed for all routes (no per-path CORS). So technically the frontend CORS-wise CAN reach admin endpoints. However, without the `ADMIN_SECRET`, the request will be rejected at the middleware level. + +**This is acceptable** — CORS is a browser-enforced mechanism. Admin requests are typically made from non-browser clients (curl, scripts) where CORS doesn't apply. The auth middleware is the actual protection layer. ✅ + +--- + +#### 7. `[N/A]` `ADMIN_SECRET` is at least 32 characters in production + +Cannot verify from code — this is a deployment configuration check. The code doesn't enforce a minimum length. + +**Recommendation:** Add a startup check: `if (config.adminSecret.length < 32) throw new Error(...)`. + +--- + +#### 8. `[PASS]` No logging middleware captures the full `Authorization` header + +- Morgan uses `combined` format in production, which does NOT include the `Authorization` header (it logs method, URL, status, referrer, user-agent). +- `supabaseAuth.ts` truncates the auth header in logs (first 15 + last 4 chars). +- `adminAuth.ts` never logs the auth header content — only logs "Error in admin authentication" on exceptions. +- No other middleware or service logs request headers. + +✅ + +--- + +#### 9. `[PASS]` Error response for invalid admin token reveals nothing about the secret + +At `adminAuth.ts:66-73`: +```typescript +res.status(httpStatus.FORBIDDEN).json({ + error: { + code: "INVALID_ADMIN_TOKEN", + message: "Invalid admin token", + status: httpStatus.FORBIDDEN + } +}); +``` + +Generic message. No hint about expected token, length, or format. ✅ + +--- + +#### 10. `[FAIL]` Admin auth errors are logged server-side with request metadata for audit trail + +At `adminAuth.ts:79`: +```typescript +logger.error("Error in admin authentication:", error); +``` + +This only logs on exception (catch block). **Successful rejections** (invalid token at line 65-73, missing header at lines 22-31) produce **no server-side log**.

The actual threshold-setting logic is in the Stellar transaction construction. This requires deeper review of `stellar.controller.ts` transaction building — deferred to Module 05 (stellar-anchors) where Stellar transaction construction is audited in detail. + +**Cross-ref:** Will be verified during Module 05 audit. + +#### 4. `[PASS]` Stellar ephemeral starting balance is bounded + +`STELLAR_EPHEMERAL_STARTING_BALANCE_UNITS = "2.5"` at `constants.ts:8`. This is 2.5 XLM — sufficient for the base reserve (1 XLM), one trustline (0.5 XLM), and transaction fees, with a small buffer. Similarly: `PENDULUM_EPHEMERAL_STARTING_BALANCE_UNITS = "0.1"` (PEN), `MOONBEAM_EPHEMERAL_STARTING_BALANCE_UNITS = "1"` (GLMR), `POLYGON_EPHEMERAL_STARTING_BALANCE_UNITS = "1.5"` (MATIC).

No network calls, no API calls. The function only writes to the local filesystem. + +#### 6. `[FAIL]` Ephemeral addresses are NOT validated for format + +**Finding (NEW — F-021).** `normalizeAndValidateSigningAccounts()` at `ramp.service.ts:63-88` validates that `account.type` is a valid `EphemeralAccountType` (Stellar, Substrate, Moonbeam, Polygon). However, `account.address` is **never validated** — no Stellar public key format check (56-char base32), no SS58 decode for Substrate, no `isAddress()` check for EVM, no length check, nothing. The address string is accepted as-is and used in transaction construction. + +An attacker could register a ramp with a malformed or empty address. This would likely cause transaction construction to fail downstream, but the failure mode is untested — it could result in confusing errors, stalled ramps, or in worst case, funds sent to an unrecoverable address. + +**Severity: 🟡 MEDIUM** — No direct fund loss (transactions with invalid addresses typically fail at the blockchain level), but it creates opportunities for DoS by submitting garbage addresses that fail in unpredictable ways deep in the pipeline. + +**Fix:** Add chain-specific address validation in `normalizeAndValidateSigningAccounts()`: +- Stellar: Validate base32 encoding, 56-char length, or use `StrKey.isValidEd25519PublicKey()` +- Substrate: Validate SS58 decode, or check against expected prefix +- EVM: Validate `isAddress()` from viem/ethers, check hex format and length + +#### 7. `[PASS]` No code path in the API logs or persists ephemeral private keys + +Confirmed by searching all `apps/api/src` for the ephemeral key generation functions and for logging patterns near address handling. The API only receives addresses (via `AccountMeta`), stores them in the database as `signingAccounts`, and uses them in transaction construction. Private keys never enter the API process. + +#### 8. `[PASS]` Each call to `generateEphemerals()` produces fresh keypairs + +At `VortexSdk.ts:169-178`, `generateEphemerals()` calls `createStellarEphemeral()`, `createPendulumEphemeral()`, and `createMoonbeamEphemeral()` directly — no caching, no memoization, no static references. Each invocation produces new random keypairs. + +#### 9. `[PASS]` Unsigned transactions are bound to specific ephemeral addresses + +Transaction construction functions (e.g., `prepareOfframpTransactions`, `prepareOnrampTransactions`) take the registered `signingAccounts` (containing the specific ephemeral addresses) and build transactions with those addresses as source/signer. This is confirmed by the ramp registration flow: `registerRamp()` stores `normalizedSigningAccounts` in the ramp state, and phase handlers read those specific addresses. + +#### 10. `[PARTIAL]` API does not check if EVM ephemeral address is an EOA + +No `getCode()` or equivalent check exists for EVM ephemeral addresses. The spec notes this as a consideration rather than a hard requirement. If an attacker submits a contract address: +- Token transfers via `transfer()` would still work (contracts can receive ERC-20) +- The contract could execute arbitrary logic on receive (e.g., re-enter) +- However, the ephemeral is controlled by the user, so this is self-harm unless the contract is specifically designed to exploit the platform + +**Assessment:** Low practical risk because the ephemeral key holder is the user themselves.

No client parameter, env var, or database config controls it. ✅ + +--- + +#### 3. `[PASS]` `discountStateTimeoutMinutes` controls discount state inactivity, NOT quote expiry + +`discountStateTimeoutMinutes` is used exclusively in `discount/helpers.ts:22`: + +```typescript +function isWithinStateTimeout(timestamp: Date, now: Date): boolean { + return now.getTime() - timestamp.getTime() < config.quote.discountStateTimeoutMinutes * 60 * 1000; +} +``` + +This controls whether the partner's `difference` is adjusted on a new quote request. It has no relationship to `QuoteTicket.expiresAt`. The two timeouts are clearly separate mechanisms that happen to share the same default value (10 minutes). ✅ + +--- + +#### 4. `[PASS]` Quotes are marked as consumed atomically with ramp creation + +At `ramp.service.ts:96`, `registerRamp()` wraps the entire operation in `this.withTransaction()`: + +```typescript +return this.withTransaction(async transaction => { + const quote = await QuoteTicket.findByPk(quoteId, { transaction }); + // ... validation ... + await this.consumeQuote(quote.id, transaction); // line 134 + handleQuoteConsumptionForDiscountState(partner); // line 141 + const rampState = await this.createRampState(...); // line 144 + // ... +}); +``` + +`consumeQuote()` at `base.service.ts:116-124`: + +```typescript +return QuoteTicket.update( + { status: "consumed" }, + { returning: true, transaction, where: { id, status: "pending" } } +); +``` + +The `where: { status: "pending" }` clause ensures atomicity — if two concurrent registrations try to consume the same quote, only one will match `status: "pending"` and succeed. The other will update 0 rows. Both quote consumption and ramp creation share the same database transaction. ✅ + +**Note:** `handleQuoteConsumptionForDiscountState()` modifies in-memory state outside the transaction — if the transaction rolls back, the discount state adjustment is NOT reverted. This is a minor inconsistency (discount state could drift by one `deltaD` step on a failed registration), but low impact given the tiny step size (0.00003). + +--- + +#### 5. `[PASS]` `deltaDBasisPoints` (default 0.3) step size + +At `discount/helpers.ts:17-19`: + +```typescript +function getDeltaD(): Big { + return new Big(config.quote.deltaDBasisPoints).div(10000); +} +``` + +With default `deltaDBasisPoints = 0.3`: `0.3 / 10000 = 0.00003` per step. This is a very small adjustment — 0.003% per step. With a 10-minute timeout between steps, it would take over 5 hours of continuous quoting to accumulate a 0.01% rate change. Reasonable granularity. ✅ + +--- + +#### 6. `[N/A]` `maxDynamicDifference` and `minDynamicDifference` values for all partners + +These are database values that cannot be verified from code alone.

If an admin endpoint or debugging tool exposes raw `QuoteTicket` records, these values would be visible.

This means: +- Quotes can be created without any authentication ✅ (by design — SDK creates quotes before user login) +- If a public API key is provided, it's validated and the partner is identified +- No `requireAuth` on quote creation + +This is intentional by design — quotes are semi-public to enable the SDK flow. Marked as PARTIAL because the spec says "verify which auth mechanisms protect quote creation." The answer is: optional auth + optional API key validation. + +--- + +#### 14. `[PARTIAL]` Quote ownership is verified at ramp registration + +At `ramp.service.ts:99-106`, the quote is looked up by ID. There is no check that the quote's `userId` or `partnerId` matches the requesting user/partner. Any caller with a valid quote ID can bind it to a ramp. + +However, the quote ID is a UUID generated server-side and not predictable. An attacker would need to know or guess a valid, non-expired, non-consumed quote ID. Combined with the 10-minute expiry and single-use consumption, the practical risk is low. + +**Assessment:** No strict ownership enforcement, but defense in depth from UUID unpredictability + expiry + single-use. Not a new finding — this is a design decision consistent with the SDK model where the same client creates the quote and registers the ramp. + +--- + +#### 15. `[PASS]` Subsidy is only calculated when `targetDiscount > 0` + +Confirmed in both discount engines: + +`offramp.ts:76-79`: +```typescript +const actualSubsidyAmountDecimal = + targetDiscount > 0 + ? calculateSubsidyAmount(adjustedExpectedOutputDecimal, actualOutputAmountDecimal, maxSubsidy) + : Big(0); +``` + +Identical pattern in `onramp.ts`. When `targetDiscount` is 0, subsidy is always 0 regardless of shortfall. ✅ + +--- + +#### 16. `[PASS]` `calculateSubsidyAmount` correctly caps at `maxSubsidy × expectedOutput` + +At `discount/helpers.ts:152-167`: + +```typescript +const maxAllowedSubsidy = expectedOutput.mul(maxSubsidyBig); +return shortfall.gt(maxAllowedSubsidy) ? maxAllowedSubsidy : shortfall; +``` + +`maxSubsidy` is treated as a fraction of `expectedOutput` (e.g., `maxSubsidy = 0.02` means cap at 2% of expected output). The multiplication semantics are correct. ✅ + +--- + +#### 17. `[PASS]` `resolveDiscountPartner` fallback to "vortex" default partner + +At `discount/helpers.ts:36-63`: + +```typescript +if (partnerId) { + const partner = await Partner.findOne({ where: { ...where, id: partnerId } }); + if (partner) return partner; +} +return Partner.findOne({ where: { ...where, name: DEFAULT_PARTNER_NAME } }); // "vortex" +``` + +Falls back to `"vortex"` when no `partnerId` is provided or when the provided partner is not found. This is intentional — all quotes get at least the default partner config. ✅ + +--- + +#### 18. `[N/A]` Monitoring exists for quotes with unusually high subsidization requirements + +No monitoring or alerting infrastructure for subsidization exists in the codebase.

These are stored in `QuoteTicket.metadata.fees` and returned in the API response as `vortexFee`, `anchorFee`, `networkFee`, `partnerFee`. + +**Path 2 — Token-config-based fees (ACTUALLY DEDUCTED):** The actual amount the user receives is determined by the `computeOutput()` method in each finalize engine, which applies fees from `getAnyFiatTokenDetails()` (token config). These use `onrampFeesBasisPoints`, `offrampFeesBasisPoints`, and fixed components. + +The two paths calculate fees independently. The only thing unifying them is that both are computed during the same quote pipeline execution, but there's no reconciliation check that compares the two results or alerts on divergence. + +**Update from deeper analysis:** The fee engine now computes fees into `ctx.fees` which is stored in the quote. The finalize engine uses its own `computeOutput()` to determine the actual output. Both are stored but applied differently — `ctx.fees` is displayed, `computeOutput()` determines the output amount. The architectural intent appears to be transitioning toward a unified model, but the transition is incomplete. + +--- + +#### 2. `[PASS]` All fee calculations use `Big.js`, never native `number` + +All fee computation in `quote-fees.ts`, `discount/helpers.ts`, `fee/index.ts`, and finalize engines uses `Big` from `big.js`. Monetary amounts are represented as `Big` or `string` (to preserve precision). The only use of native `number` is for configuration values (`markupValue`, `targetDiscount`) which are used as `Big` inputs. No arithmetic on monetary amounts uses native JS `number`. ✅ + +--- + +#### 3. `[PASS]` Negative output protection + +In both finalize engines, the output is computed and validated. The `BaseFinalizeEngine.validate()` method can be overridden to check for negative outputs. The `Big.toFixed()` with round-down mode (mode 0) cannot produce negative results from a positive computation. + +Additionally, the fee engines themselves don't subtract fees from amounts — they calculate fee values and store them. The output amount in the finalize engine is calculated independently from the swap result and discount engine, which already handles the subsidy logic that prevents the user from receiving less than quoted. + +--- + +#### 4. `[PASS]` No fee parameter is accepted from the client request body + +The `QuoteRequest` type (from the quote pipeline) accepts: `inputAmount`, `inputCurrency`, `outputCurrency`, `rampType`, `from`, `to`, `network`, `countryCode`, `apiKey`, `userId`, `partnerId`. No fee rate, fee amount, or fee override field exists. All fee parameters come from server-side configuration (token config or database). ✅ + +--- + +#### 5. `[N/A]` Fee configuration from token configs matches what's intended for each currency + +This requires reviewing the actual values in `shared/src/tokens/*/config.ts` and comparing with intended fee schedules. The code correctly reads and applies these values, but the values themselves need business review. + +--- + +#### 6. `[PASS]` `distributeFees` phase distributes using pre-signed transactions + +At `distribute-fees-handler.ts:80`: + +```typescript +const distributeFeeTransaction = this.getPresignedTransaction(state, "distributeFees"); +``` + +The fee distribution uses a pre-signed transaction that was created during ramp registration (in `prepareRampTransactions()`), which uses the quote's fee breakdown to compute exact transfer amounts. The handler submits this pre-signed transaction as-is — it doesn't recalculate fees at execution time. ✅ + +**Note:** If fees were to change between quote creation and fee distribution, the pre-signed transaction still uses the original amounts from the quote. This is correct behavior — fees are locked at quote time. + +--- + +#### 7. `[N/A]` Anchor fee deduction by external services is pre-accounted in the quoted amount + +This requires reviewing each integration-specific finalize engine (BRLA, Stellar, Monerium) to verify they account for anchor fees. The off-ramp discount engine does adjust for anchor fees: + +```typescript +const anchorFeeInBrl = ctx.fees?.displayFiat?.anchor ? new Big(ctx.fees.displayFiat.anchor) : new Big(0); +const adjustedExpectedOutputDecimal = oracleExpectedOutputDecimal.plus(anchorFeeInBrl); +``` + +This suggests the system adds the anchor fee back to the expected output before calculating subsidy, ensuring the subsidy covers the anchor fee impact. However, full verification requires tracing each integration path — deferred to Module 05 (Integrations). + +--- + +#### 8. `[PASS]` Fee changes in token config or database don't retroactively affect already-created quotes + +Quotes store their fee breakdown in `metadata.fees` (in the `QuoteTicket` table) at creation time. The ramp uses the quote's stored values. The `distributeFees` phase uses a pre-signed transaction from registration time. No code path re-fetches fee configuration during ramp execution.

The handler checks `state.errorLogs.some(log => log.phase === "moonbeamToPendulumXcm")` to detect retries. On retry, it calls `apiManager.getApiWithShuffling("moonbeam", state.id)` which uses `state.id` as UUID. The `ApiManager.getApiWithShuffling()` (line 126 of `apiManager.ts`) maintains a `usedRpcIndices` Map keyed by UUID, with a Set of used indices.

In `moonbeam-to-pendulum-handler.ts`, lines 78-89: `await waitUntilTrue(isHashRegisteredInSplitReceiver)` is called BEFORE the `executeXCM` call at line 94+. The `isHashRegisteredInSplitReceiver` function (lines 67-76) reads `xcmDataMapping` from the receiver contract and checks `result > 0n`. Both are protected by a prior `didInputTokenArriveOnPendulum()` check — if tokens already arrived, the entire flow is skipped. + +**Check 4 — Executor private key not logged:** ✅ PASS. Grep confirms no logging of `MOONBEAM_EXECUTOR_PRIVATE_KEY`. The key is only used to derive an account via `privateKeyToAccount()` and passed to `sendTransactionWithBlindRetry`. + +**Check 5 — On-chain caller validation:** ⚠️ PARTIAL. The `splitReceiverABI` is imported from `@vortexfi/shared` and used at the application level to encode `executeXCM` calls. However, the actual Solidity contract is not in this repo — it's deployed at `MOONBEAM_RECEIVER_CONTRACT_ADDRESS = 0x2AB52086e8edaB28193172209407FF9df1103CDc`. **We cannot verify from the application code alone whether the contract has an `onlyExecutor` modifier or equivalent.** The on-chain contract source needs separate verification. The app-side code correctly uses only the executor key to call it, but if the contract lacks access control, anyone could call `executeXCM`. + +**Check 6 — Pendulum→Moonbeam 3-tier recovery:** ✅ PASS. `pendulum-to-moonbeam-xcm-handler.ts` implements recovery in this exact order: +1. **Hash check (lines 102-118):** If `state.state.pendulumToMoonbeamXcmHash` exists, it checks if tokens arrived on Moonbeam. If yes, transitions. If not, waits with 2-min timeout. +2. **Token departure check (lines 121-136):** If `didTokensLeavePendulum()` returns true, the handler logs that XCM was likely submitted but hash wasn't stored, then waits for Moonbeam arrival. +3. **Fresh submit (lines 138-166):** Only if neither condition is met does the handler decode the presigned extrinsic and submit it via `submitXTokens`. The hash is stored immediately after submission (lines 157-161) to minimize the crash window. + +**Check 7 — Moonbeam balance polling with 2-min timeout:** ✅ PASS. `waitForMoonbeamArrival` (lines 88-99) uses `timeoutMs = 120000` (2 minutes) and polls every 5000ms. On timeout, it returns `false`, and the caller throws `this.createRecoverableError(...)`. + +**Check 8 — Hydration→AssetHub skips finalization:** ✅ PASS. Line 36: `await submitExtrinsic(xcmExtrinsic, hydrationNode.api, false)` — the third parameter `false` disables finalization wait. The comment on line 35 explains: "Don't wait for finalization because it somehow doesn't work on Hydration." This is an accepted risk per the spec. + +**Check 9 — Hydration nonce re-execution guard:** ⚠️ PARTIAL. Lines 26-32 of `hydration-to-assethub-xcm-phase-handler.ts`: +```ts +const currentEphemeralAccountNonce = accountData.nonce.toNumber(); +if (currentEphemeralAccountNonce !== undefined && currentEphemeralAccountNonce > nonce) { + logger.warn(`Nonce mismatch: ...`); +} +``` +**ISSUE:** The nonce check only logs a warning — it does NOT skip re-submission or transition to `complete`. The spec says "if `currentNonce > executeNonce`, the handler skips re-submission and transitions directly to `complete`." The code continues to submit the extrinsic regardless. This means if a crash occurs after the XCM was sent but before the phase transition, the retry will attempt to re-submit with a stale nonce. The Substrate runtime will likely reject it (nonce too low), causing the error path to be triggered. While not a double-execution risk (the chain rejects stale nonces), it's unnecessary error churn and doesn't match the spec's intent. **→ F-028** + +**Check 10 — Hydration swap uses presigned extrinsic:** ✅ PASS. Line 24: `this.getPresignedTransaction(state, "hydrationSwap")`. Line 26: `decodeSubmittableExtrinsic(hydrationSwap as string, hydrationNode.api)`.

Lines 37-49 define `didInputTokenArriveOnHydration()` which checks Hydration balance for the swap input asset. Line 68: `await waitUntilTrue(didInputTokenArriveOnHydration, 60000)` waits with a 60-second timeout. On success, transitions to `"hydrationSwap"`. + +**Check 13 — No XCM handler logs private keys:** ✅ PASS. Confirmed via grep — no handler logs `MOONBEAM_EXECUTOR_PRIVATE_KEY`, `PENDULUM_FUNDING_SEED`, or any private key material. Only addresses, transaction hashes, and balances are logged. + +**Check 14 — Moonbeam→Pendulum blind retry budget isolation:** ⚠️ PARTIAL. In `moonbeam-to-pendulum-handler.ts`, lines 109-126, the retry loop runs up to 5 attempts with 20-second delays. Each invocation of `executePhase` is one attempt from the phase processor's perspective. However, the 5-attempt loop is INSIDE a single `executePhase` call, meaning one phase processor attempt = up to 5 contract calls. The spec asks whether this "does not consume the phase processor's retry budget." **It does not directly consume it** — the phase processor sees one attempt regardless of how many retries happen internally. But if all 5 fail, the error propagates, and the phase processor will invoke `executePhase` again with its own retry budget, leading to 5 × N total contract calls where N = phase processor retries. This is the expected behavior per the spec's threat analysis (5 × 8 = 40 max), but worth noting. Additionally, `maxFeePerGas` and `maxPriorityFeePerGas` are estimated once (line 105) before the loop and reused across all 5 attempts — if gas prices change during the 100-second window, later attempts may underprice. **→ F-028 (combined with nonce issue)** + +### Checklist Summary — XCM Transfers + +| # | Check | Result | +|---|---|---| +| 1 | RPC shuffling persistence | ✅ PASS | +| 2 | 30min RecoverablePhaseError | ✅ PASS | +| 3 | Hash registration before executeXCM | ✅ PASS | +| 4 | Executor key not logged | ✅ PASS | +| 5 | On-chain caller validation | ⚠️ PARTIAL — cannot verify from app code | +| 6 | 3-tier recovery | ✅ PASS | +| 7 | 2-min Moonbeam balance timeout | ✅ PASS | +| 8 | Hydration finalization skip | ✅ PASS — accepted risk | +| 9 | Hydration nonce guard | 🔴 FAIL — F-028 (warning-only, no skip) | +| 10 | Hydration swap presigned | ✅ PASS | +| 11 | Pendulum→AssetHub terminal phase | ✅ PASS | +| 12 | Pendulum→Hydration balance wait | ✅ PASS | +| 13 | No private key logging | ✅ PASS | +| 14 | Retry budget isolation | ⚠️ PARTIAL — stale gas price across retries | + +--- + +### 6.2 Bridge Security — Spacewalk + +#### Checklist Results + +| # | Check | Result | +|---|---|---| +| 1 | `createVaultService()` filters by both `assetCode` AND `assetIssuer` | ✅ PASS | +| 2 | Vault capacity check before selection | ✅ PASS | +| 3 | Redeem extrinsic decoded from presigned data | ✅ PASS | +| 4 | Nonce guard identifies prior execution | ✅ PASS | +| 5 | `AmountExceedsUserBalance` catch does NOT re-submit | ✅ PASS | +| 6 | `isStellarEphemeralFunded()` checks existence AND trustline | ✅ PASS | +| 7 | 10-minute balance polling timeout | ✅ PASS | +| 8 | No fallback to default vault on failure | ✅ PASS | +| 9 | Vault slash/cancel mechanism documented | ⚠️ PARTIAL — documented in spec, no operational runbook | +| 10 | `@ts-ignore` on `.nonce.toNumber()` | 🟡 EXISTING FINDING — F-026 | +| 11 | Spacewalk maximum redeem amount per vault | ⚠️ PARTIAL — not validated in app code | +| 12 | No claimable-balance recovery mechanism | ✅ PASS — confirmed absent, documented as gap | + +#### Detailed Analysis + +**Check 1 — Vault filtering by both `assetCode` AND `assetIssuer`:** ✅ PASS. `getVaults.ts` lines 31-39: `getVaultsForCurrency()` filters vaults with both conditions: +- `vault.id.currencies.wrapped.asStellar.asAlphaNum4.code.toString() === assetCodeHex` +- `vault.id.currencies.wrapped.asStellar.asAlphaNum4.issuer.toString() === assetIssuerHex` +Both are AND-ed in the filter predicate along with `vaultHasEnoughRedeemable()`. + +**Check 2 — Capacity check before selection:** ✅ PASS.

The `submitRedeem` method uses `this.vaultId` only.

The spec's Threat Vectors section documents the vault collateral slash mechanism. However, there is no operational runbook referenced in the codebase. The slash/cancel is a Spacewalk protocol mechanism that operates independently of Vortex code, but operations teams should know how to invoke cancel-redeem if needed. + +**Check 10 — `@ts-ignore` on `.nonce.toNumber()`:** 🟡 EXISTING FINDING (F-026). Same pattern as identified in Module 05. Line 72: `// @ts-ignore` before `accountData.nonce.toNumber()`. + +**Check 11 — Spacewalk max redeem per vault per tx:** ⚠️ PARTIAL. The app code checks vault capacity via `vaultHasEnoughRedeemable()` which compares `issuedTokens - toBeRedeemedTokens > redeemableAmount`. However, this is Vortex's check based on chain state. Whether Spacewalk itself enforces a per-transaction maximum (separate from available capacity) is a protocol-level question not verifiable from the app code. No explicit per-tx maximum check exists in the Vortex code. + +**Check 12 — No claimable-balance recovery:** ✅ PASS (confirming absence as known gap). The `isStellarEphemeralFunded()` pre-check prevents this scenario, but if bypassed, there is no recovery mechanism. No code path handles claimable balances.

The swap amount is calculated from the subsidy shortfall (line 196: `subsidyAmountRaw.div(rate).mul(1.1).toFixed(0)` — the 1.1x buffer accounts for slippage). The amount is then checked against `MAX_FINAL_SETTLEMENT_SUBSIDY_USD` (lines 210-213). However, as established in F-001, the cap check doesn't actually throw, so the swap input is effectively unbounded. The rate-based calculation provides some natural bounding (it's derived from the subsidy shortfall), but without the cap enforcement, a manipulated price feed or extreme shortfall could result in an excessive swap. + +**Check 10 — Retry loop on malicious route:** 🔴 FAIL.

Two concurrent rebalancer instances would read the same state, both proceed, and both overwrite each other's progress. + +However, examining `index.ts` (lines 52-59): the rebalancer runs as a one-shot process that calls `checkForRebalancing()` then `process.exit(0)`. It is NOT a long-running server. It accepts `--restart` and optional manual amount as CLI args. This means concurrent execution risk depends entirely on the deployment trigger (cron, CI/CD, manual).

In `index.ts` line 32, the check is: +```ts +if (brlaPool.coverageRatio >= 1 + config.rebalancingThreshold && usdcAxlPool.coverageRatio <= 1) +``` + +This triggers rebalancing when BRLA pool coverage ratio is ≥ 1.25 AND USDC.axl pool coverage ratio is ≤ 1.0. This is a reasonable threshold — it only rebalances when there's a genuine surplus in one pool and deficit in another. The threshold is configurable via env var. + +Note: The spec says threshold is 0.25 (25%) and the code uses it as `1 + threshold`. The spec described it slightly differently ("falls below"), but the actual implementation is "BRLA overfull AND USDC.axl underfull" which is correct for a BRLA→axlUSDC rebalancing direction. + +--- + +#### Checklist Item 6: Rebalancer private keys distinct from API service keys + +**`[PASS]`** + +In `config.ts` lines 6-8, the rebalancer uses: +- `PENDULUM_ACCOUNT_SECRET` (mnemonic → sr25519 keypair via Keyring) +- `MOONBEAM_ACCOUNT_SECRET` (mnemonic → EVM account via `mnemonicToAccount`) +- `POLYGON_ACCOUNT_SECRET` (mnemonic → EVM account via `mnemonicToAccount`) + +In `apps/api/src/constants/constants.ts`, the API uses: +- `PENDULUM_FUNDING_SEED` +- `MOONBEAM_EXECUTOR_PRIVATE_KEY` +- `FUNDING_SECRET` (Stellar) + +Different env var names.

All env vars are loaded at startup. To rotate, the service must be restarted with new env vars. This is an operational limitation documented in the spec. + +--- + +#### Checklist Item 4: No secrets hardcoded in source code + +**`[PASS]`** + +Grep for hardcoded secret patterns (`private_key = "..."`, `secret = "..."`, `password = "..."`) across `apps/api/src/` returned no matches. All secrets are loaded from `process.env`. The only hardcoded value is the `brlaBusinessAccountAddress` in the rebalancer, which is an address, not a secret. + +In `config/vars.ts`, default values exist for database credentials (`password: "postgres"`) — but these are development defaults, not production secrets. The API validates required secrets at startup and exits if missing (`index.ts` lines 31-44). + +--- + +#### Checklist Item 5: No secrets in log output + +**`[PASS]`** + +Grep for logger calls containing secret-related patterns found: +- `adminAuth.ts:50` — `logger.error("ADMIN_SECRET not configured in environment variables")` — logs the NAME, not the value ✅ +- `apiKeyAuth.helpers.ts:160,173` — `logger.error("Failed to update lastUsedAt for secret key:", err)` — logs the error, not the key value ✅ +- `offrampTransaction.ts:45` — `logger.error("Stellar funding secret not defined")` — logs the NAME, not the value ✅ + +No instances of actual secret values being logged. Error messages reference env var names only. + +--- + +#### Checklist Item 6: `SUPABASE_SERVICE_KEY` not exposed to frontend + +**`[PASS]`** + +`SUPABASE_SERVICE_KEY` is loaded in `config/vars.ts` as `supabase.serviceRoleKey` and in the rebalancer's `config.ts` as `supabaseServiceKey`. It's used server-side for database operations. No API endpoint returns this key to clients. The frontend uses `SUPABASE_ANON_KEY` (prefixed with `VITE_` for Vite exposure). No route returns `process.env` or server configuration objects. + +--- + +#### Checklist Item 7: Database credentials not accessible from public internet + +**`[N/A]`** + +This is an infrastructure/network configuration check, not verifiable from code. The code uses `DB_HOST` (default `localhost`) which suggests local/VPC access, but actual network configuration requires infrastructure review. + +--- + +#### Checklist Item 8: `.env.example` contains no real secrets + +**`[PASS]`** + +- `apps/rebalancer/.env.example`: Contains only placeholder values (`your_api_key_here`, `your_secret_here`, `your_password_here`, `your_supabase_url_here`, etc.) ✅ +- The API's `.env.example` was not checked in this pass but was reviewed in Module 01 audit — contained only placeholders. + +--- + +#### Checklist Item 9: `.env` in `.gitignore` + +**`[PASS]`** + +- Root `.gitignore` line 14: `apps/api/.env` ✅ +- `apps/rebalancer/.gitignore` line 19: `.env` ✅ + +Both service `.env` files are excluded from version control. + +--- + +#### Checklist Item 10: Rebalancer keys different from API keys + +**`[PASS]`** + +The rebalancer uses `PENDULUM_ACCOUNT_SECRET`, `MOONBEAM_ACCOUNT_SECRET`, `POLYGON_ACCOUNT_SECRET`. The API uses `PENDULUM_FUNDING_SEED`, `MOONBEAM_EXECUTOR_PRIVATE_KEY`, `FUNDING_SECRET`. Different env var names ensure architectural separation. Actual key isolation depends on operators using different secrets — not verifiable from code. + +--- + +#### Checklist Item 11: `ADMIN_SECRET` entropy + +**`[N/A]`** + +The `ADMIN_SECRET` value is loaded from env vars. Its entropy depends on the production value chosen by operators. The code in `adminAuth.ts` line 49 checks `if (!config.adminSecret)` and rejects if empty. No minimum length or complexity enforcement in code — the secret is compared via `safeCompare()` which works for any string. + +--- + +#### Checklist Item 12: No endpoint returns env vars or server config + +**`[PASS]`** + +Reviewed all 27 route files. No endpoint returns `process.env` or the `config` object. The `/v1/status` endpoint returns chain connectivity status (Stellar, Pendulum, Moonbeam public keys), not server internals. The `/v1/ip` endpoint returns only `request.ip`. The `/v1/public-key` endpoint returns only the RSA public key for webhook verification. + +The error handler in `error.ts` strips stack traces when `env !== "development"` (line 30). Error responses include `code`, `message`, and optionally `errors` array — but not server configuration or env vars. + +--- + +#### Checklist Item 13: `GOOGLE_PRIVATE_KEY` newline handling + +**`[PASS]`** + +In `config/vars.ts` line 109: +```ts +key: process.env.GOOGLE_PRIVATE_KEY?.split(String.raw`\n`).join("\n") +``` + +The code explicitly handles the common PEM newline issue by splitting on literal `\n` escape sequences and joining with actual newlines. This correctly handles PEM keys stored as single-line env vars with escaped newlines. + +--- + +#### Checklist Item 14: Full blast radius mapping + +**`[PASS — confirmed as comprehensive]`** + +The spec's secret inventory table comprehensively maps every secret, its purpose, and its blast radius.

No wildcard `*`, no `origin: true`, no callback that echoes back the request origin. The `credentials: true` option is set, which requires a specific origin (not `*`). The implementation is correct — explicit origin whitelist. + +The CORS config also explicitly lists `allowedHeaders: ["Content-Type", "Authorization"]`. The `X-API-Key` header used by `apiKeyAuth.ts` is NOT in the allowed headers list. This means browsers making CORS requests with `X-API-Key` would have the header stripped. However, since `X-API-Key` is used for server-to-server SDK calls (not browser-to-API), this is likely intentional. + +--- + +#### Checklist Item 5: Rate limit bypass via `X-Forwarded-For` + +**`[PASS]`** + +In `express.ts` line 43: `app.set("trust proxy", Number(rateLimitNumberOfProxies))`. Default is `1` proxy. `express-rate-limit` uses `req.ip` which respects `trust proxy`. Setting `trust proxy` to a specific number (not `true`) prevents arbitrary `X-Forwarded-For` spoofing — only the Nth-from-last IP in the chain is trusted. This is correct for typical single-proxy (load balancer) deployments. + +--- + +#### Checklist Item 6: Helmet configured with secure defaults + +**`[PASS]`** + +In `express.ts` line 72: `app.use(helmet())`. Helmet is called with default configuration, which enables: +- `X-Frame-Options: SAMEORIGIN` +- `X-Content-Type-Options: nosniff` +- `Strict-Transport-Security` (HSTS) +- `X-XSS-Protection` +- `Referrer-Policy` +- `Content-Security-Policy` (default) +- Others + +No protections are explicitly disabled. Default Helmet is the recommended configuration. + +--- + +#### Checklist Item 7: `NODE_ENV` set to production + +**`[N/A]`** + +Cannot verify runtime env var from code. In `config/vars.ts` line 78: `env: process.env.NODE_ENV || "production"`. The default fallback is `"production"`, which is the safe default — stack traces are stripped unless explicitly set to `"development"`. + +--- + +#### Checklist Item 8: Error responses — no internal error types/SQL fragments + +**`[PASS]`** + +In `error.ts`: +- `handler` (line 21-36): Constructs response with `code`, `errors`, `message`. Stack trace is included but deleted when `env !== "development"`. +- `converter` (line 44-66): Converts `ValidationError` to `APIError` with generic "Validation Error" message. Other errors use `err.message` — which could potentially contain database error messages. +- `notFound` (line 72-77): Returns static "Not found" message. + +The `errors` array comes from `express-validation` which contains field names from the request (user-facing), not database internals. However, for non-validation errors, `err.message` is passed directly. If a Sequelize error message propagates (e.g., "column X does not exist"), it would be exposed. This is a theoretical risk — Sequelize errors typically hit the generic error converter. + +--- + +#### Checklist Item 9: `errors` array contains only user-facing messages + +**`[PASS]`** + +Validator error messages in `validators.ts` reference user-facing field names: `"Missing accountId or maxTime parameter"`, `"Invalid provider"`, `"Invalid sourceCurrency"`, etc. These don't leak database column names or internal structure. The `errors` array in `APIError` is populated by `express-validation` which also uses request field names. + +--- + +#### Checklist Item 10: Map all 27 routes — verify auth middleware + +**`[PARTIAL — see F-037]`** + +Full route audit completed in checklist item 3 above.

It correctly does not authenticate — the comment in the middleware says "This is for tracking purposes - validates the key exists but doesn't enforce authentication." No mutable endpoint relies solely on `publicKeyAuth` for authorization. + +--- + +#### Checklist Item 12: Controllers don't pass raw `req.body` to database + +**`[N/A — deferred]`** + +This requires reviewing all controller implementations, which was partially done in earlier modules. The validators check for required fields but do NOT strip unknown fields — `req.body` passes through unchanged. However, the controllers reviewed in earlier modules (ramp, quote, subsidize) destructure specific fields rather than passing raw `req.body`. Full controller review would require checking all 27 controllers — deferring to future audit iteration. + +--- + +#### Checklist Item 13: No endpoint returns `process.env` or internal paths + +**`[PASS]`** + +Verified across all route files. No endpoint handler returns `process.env`, `config`, or server-internal paths. The `/v1/status` endpoint returns chain connectivity status (public keys). The `/v1/ip` endpoint returns `request.ip`.

The `getMemoFromCookiesMiddleware` in `auth.ts` reads `cookies[cookieKey]` where `cookieKey = authToken_${address}`. This cookie is set by the frontend (Supabase client-side), not by the server. + +The server does not set cookies itself — it only reads them. Cookie attributes (`SameSite`, `HttpOnly`, `Secure`) are controlled by the frontend Supabase client, not the API. The CORS config includes `credentials: true`, which allows cookies to be sent cross-origin from whitelisted origins only. + +No CSRF tokens are used for state-changing operations. However, the primary auth mechanism for sensitive endpoints is `Authorization: Bearer` headers (not auto-attached by browsers), which are inherently CSRF-safe. The cookie-based auth (`getMemoFromCookiesMiddleware`) is only used on `/stellar/sep10` for SIWE memo derivation — limited attack surface. + +--- + +#### Checklist Item 15: 404 handler — no framework information leak + +**`[PASS]`** + +In `error.ts` lines 72-77: +```ts +export const notFound = (req: Request, res: Response, next: NextFunction): void => { + const err = new APIError({ message: "Not found", status: httpStatus.NOT_FOUND }); + return handler(err, req, res, next); +}; +``` + +Returns a generic "Not found" JSON response through the same error handler.

The error object is created but never thrown, so execution continues past the cap check. The `MAX_FINAL_SETTLEMENT_SUBSIDY_USD` constant provides zero protection. + +**Fix:** Add `throw` before `this.createUnrecoverableError(...)`. + +--- + +### F-002: Dual Fee System Discrepancy + +| Field | Value | +|---|---| +| **Location** | Token-config-based fees (used for deductions) vs. database-stored fees (displayed only) | +| **Spec** | `03-ramp-engine/fee-integrity.md` | +| **Status** | 🔴 **OPEN — requires architectural decision** | +| **Impact** | Fees shown to the user may not match fees actually deducted. Silent divergence over time. | + +**Description:** Two parallel fee calculation paths exist. Token-config-based fees are what actually deduct from user amounts during swaps. Database-based fees are calculated, stored, and displayed — but are NOT used for actual deductions. These two systems can produce different numbers for the same ramp, meaning users may see one fee but pay another. + +**Fix:** Unify the fee systems or add reconciliation checks that alert on divergence. + +--- + +## 🟠 High — Open + +### F-003: Phase Processor Lock is Non-Atomic + +| Field | Value | +|---|---| +| **Location** | `apps/api/src/api/services/phases/phase-processor.ts` | +| **Spec** | `03-ramp-engine/state-machine.md` | +| **Status** | 🟠 **OPEN** | +| **Impact** | Two API instances could process the same ramp simultaneously, causing double-execution of phase handlers (double swaps, double XCM transfers). | + +**Description:** Lock acquisition reads `state.processingLock.locked` from a potentially stale DB read, then sets it in a separate UPDATE. No `SELECT FOR UPDATE`, advisory lock, or atomic compare-and-swap. The in-memory `Set` only protects within a single Node.js process. + +**Fix:** Use `SELECT FOR UPDATE` or database advisory locks for cross-instance safety. + +--- + +### F-004: Infinite Soft Loop After Max Retries + +| Field | Value | +|---|---| +| **Location** | `apps/api/src/api/services/phases/phase-processor.ts` | +| **Spec** | `03-ramp-engine/state-machine.md` | +| **Status** | 🟠 **OPEN** | +| **Impact** | Ramps that exhaust their retry budget stay in the current phase indefinitely. On each processing cycle, they are retried again — consuming resources and potentially repeating side effects. | + +**Description:** After `MAX_RETRIES` (8) is exhausted for a recoverable error, the ramp stays in its current phase. It is not transitioned to `failed`. The next processing cycle picks it up again and the retry counter restarts. + +**Fix:** Transition to `failed` after max retries exhausted, or persist the retry counter so it survives across processing cycles. + +--- + +### F-005: No Secrets Manager / No Rotation Mechanism + +| Field | Value | +|---|---| +| **Location** | All services — `apps/api/src/config/vars.ts`, `apps/rebalancer/src/utils/config.ts` | +| **Spec** | `07-operations/secret-management.md` | +| **Status** | 🟠 **OPEN — operational gap** | +| **Impact** | Server compromise exposes every funding key, database credential, and third-party API key. No way to rotate without full redeployment. No access logging for secret usage. | + +**Description:** All secrets are plain environment variables loaded at startup. No HSM, no secrets manager (AWS Secrets Manager, Vault, etc.), no encrypted storage at rest, no audit trail. Blast radius of a server compromise is total: Stellar funding keys, Pendulum seeds, Moonbeam executor keys, all rebalancer chain keys, database credentials, admin tokens, and all third-party API keys. + +**Fix:** Adopt a secrets manager with access logging and rotation support. At minimum, separate high-value keys (funding/signing) from low-value keys (API tokens). + +--- + +### F-006: Rebalancer State File — No Locking + +| Field | Value | +|---|---| +| **Location** | `apps/rebalancer/src/services/stateManager.ts` | +| **Spec** | `07-operations/rebalancer.md` | +| **Status** | 🟠 **OPEN** | +| **Impact** | Concurrent rebalancer executions could corrupt state and cause double-execution of swaps/XCMs. | + +**Description:** Rebalancer state is stored as a JSON file in Supabase Storage. Supabase Storage has no file locking, no conditional writes, no atomic compare-and-swap. If two instances run simultaneously, both read the same state and could execute the same steps. + +**Fix:** Add a locking mechanism (e.g., DB-based lock, advisory lock) or ensure single-instance deployment. + +--- + +## 🟡 Medium — Open + +### F-007: 50MB Body Parser Limit + +| Field | Value | +|---|---| +| **Location** | `apps/api/src/config/express.ts` | +| **Spec** | `07-operations/api-surface.md` | +| **Status** | 🟡 **OPEN** | +| **Impact** | Memory exhaustion via large request bodies. At 100 req/min rate limit, an attacker can push ~5GB/min of memory pressure per IP. | + +**Description:** `bodyParser.json({ limit: "50mb" })` is configured. Typical JSON APIs use 1-10MB. A 50MB limit combined with the global rate limit (100 req/min) allows significant memory pressure. + +**Fix:** Reduce to 1-10MB unless a specific endpoint requires large payloads. + +--- + +### F-008: Staging CORS Origin in Production + +| Field | Value | +|---|---| +| **Location** | `apps/api/src/config/express.ts` | +| **Spec** | `07-operations/api-surface.md` | +| **Status** | 🟡 **OPEN** | +| **Impact** | If the staging site is compromised or has XSS, it becomes a CORS-allowed origin for the production API. | + +**Description:** `staging--pendulum-pay.netlify.app` is in the CORS whitelist alongside production domains. This means the staging site can make authenticated cross-origin requests to production. + +**Fix:** Remove staging origins from production CORS config. Use environment-specific CORS lists. + +--- + +### F-009: Hydration XCM Skips Finalization + +| Field | Value | +|---|---| +| **Location** | `apps/api/src/api/services/phases/handlers/hydration-to-assethub-xcm-phase-handler.ts` | +| **Spec** | `06-cross-chain/xcm-transfers.md` | +| **Status** | 🟡 **OPEN — accepted risk (needs documentation)** | +| **Impact** | A Hydration chain reorganization could revert the XCM transfer after the ramp has already transitioned to `complete`. | + +**Description:** `submitExtrinsic` is called with `waitForFinalization=false` because "it somehow doesn't work on Hydration." The handler proceeds after inclusion. If the chain reorganizes, the transfer is reverted but the ramp is already marked complete. + +**Fix:** Document as accepted risk with reasoning. Monitor Hydration block finality characteristics. Consider post-hoc verification. + +--- + +### F-010: `safeCompare` Leaks Admin Secret Length + +| Field | Value | +|---|---| +| **Location** | `apps/api/src/api/middlewares/adminAuth.ts` | +| **Spec** | `01-auth/admin-auth.md` | +| **Status** | 🟡 **OPEN** | +| **Impact** | Timing side-channel reveals the length of `ADMIN_SECRET`. Attacker can determine secret length before attempting brute force. | + +**Description:** `safeCompare()` returns early on `a.length !== b.length`. While the character-by-character comparison is constant-time, the length check is not. An attacker can probe with different-length tokens to determine the exact length of the admin secret. + +**Fix:** Pad or hash both inputs to equal length before comparison. Or use `crypto.timingSafeEqual` with equal-length buffers. + +--- + +### F-011: Ephemeral Webhook RSA Keys + +| Field | Value | +|---|---| +| **Location** | `apps/api/src/config/crypto.ts` | +| **Spec** | `02-signing-keys/server-side-signing.md` | +| **Status** | 🟡 **OPEN — operational gap** | +| **Impact** | Webhook signatures change on every restart. Consumers lose ability to verify signatures from the previous instance. | + +**Description:** If `WEBHOOK_PRIVATE_KEY` is not set, `CryptoService` generates an ephemeral RSA keypair at startup. This key is non-persistent: webhook signatures generated before a restart cannot be verified after, and vice versa. + +**Fix:** Ensure `WEBHOOK_PRIVATE_KEY` is always set in production. Add a startup check that fails if missing. + +--- + +## 🟡 Medium — Informational / Lower Priority + +### F-012: Dynamic Pricing State In-Memory Only + +| Field | Value | +|---|---| +| **Location** | `apps/api/src/api/services/quote/engines/discount/helpers.ts` | +| **Spec** | `03-ramp-engine/quote-lifecycle.md` | +| **Status** | 🟡 **OPEN — known limitation** | +| **Impact** | Server restart resets all partner discount states. Partners lose accumulated rate adjustments, causing abrupt rate changes. | + +**Description:** The `partnerDiscountState` Map is in-memory only. All dynamic pricing state (the `difference` value per partner) is lost on restart. + +**Fix:** Persist to database if continuity across restarts matters. Or accept as design decision with documentation. + +--- + +## 🔴 Critical — Open (Audit Phase) + +### F-013: Multiple Security-Sensitive Endpoints Have No Authentication + +| Field | Value | +|---|---| +| **Location** | `apps/api/src/api/routes/v1/ramp.route.ts`, `pendulum.route.ts`, `subsidize.route.ts`, `moonbeam.route.ts`, `stellar.route.ts`, `webhook.route.ts`, `brla.route.ts`, `maintenance.route.ts` | +| **Spec** | `00-system-overview/architecture.md` | +| **Status** | 🔴 **OPEN — requires architectural decision** | +| **Found** | Code audit, iteration 2 | +| **Impact** | Attacker can start ramps, trigger XCM execution, fund ephemeral accounts, and initiate subsidization — all spending platform funds — without any authentication. | + +**Description:** The following endpoints have **zero authentication middleware**: + +- `POST /v1/ramp/start` — starts ramp phase processing +- `POST /v1/ramp/update` — updates ramp with presigned transactions +- `GET /v1/ramp/:id` — reads full ramp state (including internal details) +- `POST /v1/pendulum/fundEphemeral` — triggers funding from platform wallet +- `POST /v1/subsidize/preswap`, `POST /v1/subsidize/postswap` — triggers subsidization +- `POST /v1/moonbeam/execute-xcm` — triggers cross-chain message execution +- `POST /v1/stellar/create` — requests Stellar transaction signatures +- `POST /v1/webhook/`, `DELETE /v1/webhook/:id` — register/delete webhooks +- `PATCH /v1/maintenance/schedules/:id/active` — toggle maintenance mode +- `GET /v1/brla/getUser`, `GET /v1/brla/getUserRemainingLimit`, etc. — user data without auth + +**Note:** Some of these may be intentionally unauthenticated because the SDK calls them after the user has signed transactions client-side (the presigned tx itself acts as implicit authorization). If so, this design decision should be explicitly documented and additional validations (e.g., verifying the ramp is in the correct state, the caller provided valid presigned data) should be verified. + +**Fix:** For each endpoint, either: (1) add appropriate auth middleware, or (2) document why auth is not needed and what alternative authorization mechanism is in place. + +--- + +## 🟠 High — Open (Audit Phase) + +### F-014: Most External HTTP Calls Lack Timeout Configuration + +| Field | Value | +|---|---| +| **Location** | `apps/api/src/api/services/monerium/index.ts`, `priceFeed.service.ts`, `moonpay/moonpay.service.ts`, `transak/transak.service.ts`, `alchemypay/alchemypay.service.ts`, `ramp/helpers.ts`, `distribute-fees-handler.ts`, `slack.service.ts` | +| **Spec** | `00-system-overview/architecture.md` | +| **Status** | 🟠 **OPEN** | +| **Found** | Code audit, iteration 2 | +| **Impact** | A hanging external service can block the caller indefinitely. For phase handlers, this stalls ramp processing. For price feeds, this stalls quote generation. | + +**Description:** Of 16+ `fetch()` calls to external services, only `webhook-delivery.service.ts` uses `AbortController` with a timeout. All others (Monerium, CoinGecko, Moonpay, Transak, AlchemyPay, Subscan, Slack, ramp helpers) make HTTP requests without any timeout or `AbortSignal`. + +**Fix:** Add `AbortController` with appropriate timeouts (e.g., 10-30s) to all external `fetch()` calls. Consider a shared utility function like `fetchWithTimeout(url, options, timeoutMs)`. + +--- + +## 🟡 Medium — Open (Audit Phase) + +### F-015: Internal Error Messages Leaked in API Responses + +| Field | Value | +|---|---| +| **Location** | `apps/api/src/api/middlewares/error.ts`, `apps/api/src/api/middlewares/auth.ts` | +| **Spec** | `00-system-overview/architecture.md` | +| **Status** | 🟡 **OPEN** | +| **Found** | Code audit, iteration 2 | +| **Impact** | Internal error messages may reveal implementation details to attackers (library names, internal paths, database errors). | + +**Description:** While stack traces are correctly stripped in production, the `err.message` from arbitrary internal errors is passed through to API responses via the `converter` middleware. Additionally, `auth.ts:58` includes `details: err.message` in the response. Internal error messages can contain database connection errors, file paths, or other sensitive information. + +**Fix:** In production, replace internal error messages with generic messages (e.g., "Internal server error") unless the error is a known user-facing `APIError`. Only pass through messages from errors explicitly created for user consumption. + +--- + +### F-016: Funding Seed Accessed Directly via `process.env` + +| Field | Value | +|---|---| +| **Location** | `apps/api/src/api/services/pendulum/pendulum.service.ts:9` | +| **Spec** | `00-system-overview/architecture.md` | +| **Status** | 🟡 **OPEN** | +| **Found** | Code audit, iteration 2 | +| **Impact** | High-value signing key bypasses centralized config, making future secret rotation and access auditing harder. | + +**Description:** `const { PENDULUM_FUNDING_SEED } = process.env;` accesses the funding seed directly instead of through `config/vars.ts`. Other services (`slack.service.ts`, `priceFeed.service.ts`) also access `process.env` directly for API keys. + +**Fix:** Move all `process.env` access to `config/vars.ts`. Access all secrets through the centralized config object. + +--- + +## 🔵 Low — Open (Audit Phase) + +### F-017: Database TLS Not Explicitly Configured + +| Field | Value | +|---|---| +| **Location** | `apps/api/src/config/database.ts` | +| **Spec** | `00-system-overview/architecture.md` | +| **Status** | 🔵 **OPEN — needs verification** | +| **Found** | Code audit, iteration 2 | +| **Impact** | If the database server does not enforce TLS, connections could be unencrypted, exposing credentials and data in transit. | + +**Description:** The Sequelize configuration does not include `dialectOptions.ssl`. Whether TLS is used depends entirely on the database server configuration. If using Supabase Postgres, TLS is likely enforced server-side, but this should be explicitly configured. + +**Fix:** Add `dialectOptions: { ssl: { require: true, rejectUnauthorized: true } }` to the Sequelize configuration for production. + +--- + +### F-018: Token Verification Uses Anon-Key Supabase Client Instead of Service-Role Client + +| Field | Value | +|---|---| +| **Location** | `apps/api/src/api/services/auth/supabase.service.ts:147` | +| **Spec** | `01-auth/supabase-otp.md` | +| **Status** | 🔵 **OPEN — low risk** | +| **Found** | Code audit, iteration 2 | +| **Impact** | Functionally correct but deviates from spec and best practice. Future Supabase auth API changes could affect behavior. | + +**Description:** `SupabaseAuthService.verifyToken()` calls `supabase.auth.getUser(accessToken)` using the anon-key client, not `supabaseAdmin.auth.getUser(accessToken)` with the service-role key. The `getUser()` method sends the token to Supabase's server for verification regardless of which client is used, so token verification is server-side in both cases. However, the spec explicitly requires "MUST use `SUPABASE_SERVICE_KEY`." + +**Fix:** Change `supabase.auth.getUser(accessToken)` to `supabaseAdmin.auth.getUser(accessToken)` at `supabase.service.ts:147`. + +--- + +### F-019: No Startup Validation for Supabase Configuration + +| Field | Value | +|---|---| +| **Location** | `apps/api/src/config/vars.ts:115-118`, `apps/api/src/config/supabase.ts` | +| **Spec** | `01-auth/supabase-otp.md` | +| **Status** | 🟡 **OPEN** | +| **Found** | Code audit, iteration 2 | +| **Impact** | Service starts normally with empty Supabase config — all authenticated endpoints silently return 401. No health check or startup log indicates the misconfiguration. | + +**Description:** `SUPABASE_URL`, `SUPABASE_ANON_KEY`, and `SUPABASE_SERVICE_KEY` all default to empty string `""` in `vars.ts`. No startup validation checks these values. `createClient("", "")` creates a non-functional Supabase client. `requireAuth` correctly rejects all requests (fail closed), but the failure mode is silent — the service appears healthy while all user authentication is broken. + +**Fix:** Add startup validation that terminates the process (or logs a CRITICAL warning) if any of the three Supabase config values are empty when `NODE_ENV === "production"`. + +--- + +### F-020: Failed Admin Auth Attempts Not Logged + +| Field | Value | +|---|---| +| **Location** | `apps/api/src/api/middlewares/adminAuth.ts` | +| **Spec** | `01-auth/admin-auth.md` | +| **Status** | 🟡 **OPEN** | +| **Found** | Code audit, iteration 2 | +| **Impact** | Brute-force attacks against admin endpoints are invisible in server logs. No audit trail for failed admin access attempts. | + +**Description:** The `adminAuth` middleware only logs errors that occur during the authentication process (exceptions in the catch block). Intentional rejections — missing auth header (401) and invalid token (403) — produce **no log output**. An attacker probing the admin secret would generate zero log entries. + +**Fix:** Add `logger.warn("Admin auth failed", { ip: req.ip, path: req.path, reason: "missing_header" | "invalid_token" })` for both rejection paths. + +--- + +### F-021: No Address Format Validation for Ephemeral Accounts + +| Field | Value | +|---|---| +| **Location** | `apps/api/src/api/services/ramp/ramp.service.ts:63-88` (`normalizeAndValidateSigningAccounts`) | +| **Spec** | `02-signing-keys/ephemeral-accounts.md` | +| **Status** | 🟡 **OPEN** | +| **Found** | Code audit, iteration 2 | +| **Impact** | Malformed or empty addresses accepted for ramp registration. Transactions with invalid addresses fail unpredictably deep in the pipeline, potentially stalling ramps or causing confusing errors. | + +**Description:** `normalizeAndValidateSigningAccounts()` validates that `account.type` is a valid `EphemeralAccountType` (Stellar, Substrate, Moonbeam, Polygon). However, `account.address` is **never validated** — no Stellar public key format check (56-char base32, `StrKey.isValidEd25519PublicKey()`), no SS58 decode for Substrate, no `isAddress()` for EVM, no length check. The address string is accepted as-is and stored in the ramp state, then used in transaction construction. + +**Fix:** Add chain-specific address validation in `normalizeAndValidateSigningAccounts()`: +- Stellar: `StrKey.isValidEd25519PublicKey(address)` +- Substrate: SS58 decode or prefix check +- EVM: `isAddress(address)` from viem/ethers + +--- + +### F-022: SEP-10 Master Secret Aliased to Stellar Funding Secret + +| Field | Value | +|---|---| +| **Location** | `apps/api/src/constants/constants.ts:43` (`SEP10_MASTER_SECRET = FUNDING_SECRET`) | +| **Spec** | `02-signing-keys/server-side-signing.md` | +| **Status** | 🟡 **OPEN** | +| **Found** | Code audit, iteration 2 | +| **Impact** | Key purpose separation violated. A vulnerability in the SEP-10 authentication flow that leaks key material would directly compromise the Stellar funding account. | + +**Description:** `SEP10_MASTER_SECRET` is set to `FUNDING_SECRET` at `constants.ts:43` rather than being loaded from its own environment variable.

If the route swaps tokens to an attacker address or the output is dramatically less than expected, the handler would wait for the balance check to timeout (3 minutes) and then fail — but the native tokens would already be lost. +2. **Single route fetch**: The swap route is fetched once and used for the transaction. There's no sanity check on the route's `toAmount` against the required `subsidyAmountRaw`. +3. **Retry amplification**: While the swap itself isn't retried (it's the subsidy transfer that has 5 retries), a phase processor retry would re-fetch and re-execute the swap, potentially compounding losses. + +**Fix:** After fetching the swap route, validate that `swapRoute.estimate.toAmount` is within an acceptable range of `subsidyAmountRaw` (e.g., ≥80%).

(2) Moonbeam handler: gas price estimated once and reused across 5 retries (~100s window), potentially causing later attempts to underprice. | - -**Description:** Two related issues in XCM handlers: - -1. In `hydration-to-assethub-xcm-phase-handler.ts`, the nonce guard (lines 28-32) compares `currentEphemeralAccountNonce > nonce` but only logs a warning. Unlike the Spacewalk redeem handler (which correctly skips to the waiting path), this handler continues to submit the extrinsic, which will be rejected by the chain due to stale nonce. The phase processor then retries, creating unnecessary error cycles. +| **Found** | Code audit, iteration 2 | +| **Impact** | If the database server does not enforce TLS, connections could be unencrypted, exposing credentials and data in transit. | -2. In `moonbeam-to-pendulum-handler.ts`, `estimateFeesPerGas()` is called once (line 105) before the 5-attempt retry loop (lines 109-126). Each retry waits 20 seconds — across 5 attempts, the gas estimate can become stale in volatile conditions, causing later attempts to be rejected or delayed. +**Description:** The Sequelize configuration does not include `dialectOptions.ssl`. Whether TLS is used depends entirely on the database server configuration. -**Fix:** (1) Change the Hydration handler to skip re-submission when nonce indicates prior execution, similar to `spacewalk-redeem-handler.ts`. (2) Move `estimateFeesPerGas()` inside the retry loop so each attempt uses a fresh gas estimate. +**Fix:** Add `dialectOptions: { ssl: { require: true, rejectUnauthorized: true } }` to the Sequelize configuration for production. --- -### F-030: No Output Validation on SquidRouter Swap in Final Settlement Subsidy +### F-018: Token Verification Uses Anon-Key Supabase Client Instead of Service-Role Client | Field | Value | |---|---| -| **Location** | `apps/api/src/api/services/phases/handlers/final-settlement-subsidy.ts`, lines 216-264 (swap), lines 276-309 (transfer retry) | -| **Spec** | `06-cross-chain/fund-routing.md`, Threat Vector: "SquidRouter swap manipulation" | +| **Location** | `apps/api/src/api/services/auth/supabase.service.ts:147` | +| **Spec** | `01-auth/supabase-otp.md` | | **Status** | ✅ **FIXED** | -| **Found** | Code audit, iteration 2, Module 06 | -| **Impact** | If the SquidRouter API returns a malicious or severely unfavorable route, the swap executes without verifying the output amount. The 5-attempt retry loop on the subsidy transfer could amplify losses if the route consistently underdelivers. | - -**Description:** The `final-settlement-subsidy.ts` handler performs a SquidRouter swap (native → ERC-20) to top up the funding account when it has insufficient ERC-20 balance. The swap route is fetched from the SquidRouter API (lines 216-233) and executed (lines 238-252). After the swap, the handler waits for the funding account's ERC-20 balance to meet the required subsidy amount (lines 257-264). However: +| **Found** | Code audit, iteration 2 | +| **Impact** | Functionally correct but deviates from spec and best practice. | -1. **No output validation**: The handler does not compare the actual swap output against the expected output. If the route swaps tokens to an attacker address or the output is dramatically less than expected, the handler would wait for the balance check to timeout (3 minutes) and then fail — but the native tokens would already be lost. -2. **Single route fetch**: The swap route is fetched once and used for the transaction. There's no sanity check on the route's `toAmount` against the required `subsidyAmountRaw`. -3. **Retry amplification**: While the swap itself isn't retried (it's the subsidy transfer that has 5 retries), a phase processor retry would re-fetch and re-execute the swap, potentially compounding losses. +**Description:** `SupabaseAuthService.verifyToken()` calls `supabase.auth.getUser(accessToken)` using the anon-key client, not `supabaseAdmin.auth.getUser(accessToken)` with the service-role key. The spec explicitly requires "MUST use `SUPABASE_SERVICE_KEY`." -**Fix:** After fetching the swap route, validate that `swapRoute.estimate.toAmount` is within an acceptable range of `subsidyAmountRaw` (e.g., ≥80%). If it's dramatically lower, abort with an unrecoverable error. Also consider comparing `testRoute` and `swapRoute` estimates for consistency. +**Fix:** Change `supabase.auth.getUser(accessToken)` to `supabaseAdmin.auth.getUser(accessToken)`. --- -### F-032: No Pre-Check of Pendulum Funding Account Balance in Subsidy Handlers +### F-019: No Startup Validation for Supabase Configuration | Field | Value | |---|---| -| **Location** | `apps/api/src/api/services/phases/handlers/subsidize-pre-swap-handler.ts`, lines 68-79; `subsidize-post-swap-handler.ts`, lines 100-110 | -| **Spec** | `06-cross-chain/fund-routing.md`, Invariant 8 | +| **Location** | `apps/api/src/config/vars.ts:115-118`, `apps/api/src/config/supabase.ts` | +| **Spec** | `01-auth/supabase-otp.md` | | **Status** | ✅ **FIXED** | -| **Found** | Code audit, iteration 2, Module 06 | -| **Impact** | If the Pendulum funding account runs out of tokens, subsidization transactions will be submitted and fail on-chain, consuming transaction fees and triggering opaque recoverable errors. The root cause (depleted funding account) is not surfaced in error messages. | - -**Description:** Both `subsidize-pre-swap-handler.ts` and `subsidize-post-swap-handler.ts` call `apiManager.executeApiCall()` to transfer tokens from the funding account to the ephemeral account, but neither checks the funding account's balance first. If the funding account has insufficient balance: -- The on-chain transaction reverts -- The handler catches the error in its generic catch block -- A `RecoverablePhaseError` is thrown with a generic message ("Failed to subsidize pre/post swap") -- The phase processor retries, hitting the same insufficient balance condition - -This creates a retry loop that won't resolve until the funding account is manually topped up, without clear diagnostics about what went wrong. +| **Found** | Code audit, iteration 2 | +| **Impact** | Service starts normally with empty Supabase config — all authenticated endpoints silently return 401. | -In contrast, `final-settlement-subsidy.ts` (lines 139-143) does check the EVM funding account balance before the subsidy transfer and proactively swaps native tokens if insufficient — a better pattern. +**Description:** `SUPABASE_URL`, `SUPABASE_ANON_KEY`, and `SUPABASE_SERVICE_KEY` all default to empty string `""` in `vars.ts`. No startup validation checks these values. -**Fix:** Before executing the subsidization transfer, query the funding account's balance for the target token. If insufficient, throw a clear unrecoverable error (e.g., "Funding account balance too low for subsidy: has X, needs Y"). This surfaces the issue immediately instead of creating retry loops. +**Fix:** Add startup validation that terminates the process if any of the three Supabase config values are empty when `NODE_ENV === "production"`. --- -## 🔵 Low — Open (Module 06 Audit) - -### F-031: Post-Swap Routing Has No Default Error Case +### F-020: Failed Admin Auth Attempts Not Logged | Field | Value | |---|---| -| **Location** | `apps/api/src/api/services/phases/handlers/subsidize-post-swap-handler.ts`, lines 128-148 | -| **Spec** | `06-cross-chain/fund-routing.md`, Invariant 7 | +| **Location** | `apps/api/src/api/middlewares/adminAuth.ts` | +| **Spec** | `01-auth/admin-auth.md` | | **Status** | ✅ **FIXED** | -| **Found** | Code audit, iteration 2, Module 06 | -| **Impact** | If a new ramp flow is added that reaches `subsidize-post-swap-handler` with an unrecognized combination of `direction`, `toChain`, and `outputCurrency`, the routing would silently fall through to `spacewalkRedeem`, which may not be the correct phase. | - -**Description:** The `nextPhaseSelector` method in `subsidize-post-swap-handler.ts` uses a series of `if` statements to determine the next phase: -- BUY + assethub + USDC → `pendulumToAssethubXcm` -- BUY + assethub + non-USDC → `pendulumToHydrationXcm` -- BUY + non-assethub → `pendulumToMoonbeamXcm` -- SELL + BRL → `pendulumToMoonbeamXcm` -- SELL + non-BRL → `spacewalkRedeem` (implicit default) +| **Found** | Code audit, iteration 2 | +| **Impact** | Brute-force attacks against admin endpoints are invisible in server logs. | -The final `return "spacewalkRedeem"` is an implicit catch-all. For current flows, this works correctly. However, if a future SELL flow is added with a different output currency that shouldn't go through Spacewalk (e.g., a direct EVM offramp), it would be silently routed to `spacewalkRedeem`. +**Description:** The `adminAuth` middleware only logs errors that occur during the authentication process (exceptions in the catch block). Intentional rejections — missing auth header (401) and invalid token (403) — produce no log output. -**Fix:** Add an explicit `else` clause that throws an error for unrecognized combinations: `throw new Error(\`Unrecognized routing: direction=${state.type}, to=${state.to}, output=${quote.outputCurrency}\`)`. This makes misrouting fail loudly. +**Fix:** Add `logger.warn()` for both rejection paths with IP, path, and reason. --- -## 🟠 High — Open (Module 07 Audit) - -### F-033: Rebalancer Steps Not Idempotent — Double-Spend on Crash Recovery +### F-021: No Address Format Validation for Ephemeral Accounts | Field | Value | |---|---| -| **Location** | `apps/rebalancer/src/rebalance/brla-to-axlusdc/index.ts` (orchestrator); `apps/rebalancer/src/rebalance/brla-to-axlusdc/steps.ts` (step implementations) | -| **Spec** | `07-operations/rebalancer.md`, Invariant 3 | -| **Status** | 🟠 **OPEN — requires code fix** | -| **Found** | Code audit, iteration 2, Module 07 | -| **Impact** | A crash between step execution and `saveState()` causes the step to re-execute on next run, leading to double swaps, double XCM transfers, or duplicate BRLA withdrawal tickets — all resulting in direct fund loss. | - -**Description:** The rebalancer is an 8-step state machine that persists progress to Supabase Storage (JSON file).

Threat & Trust Model + +### Protocol Threat Profile + +> Protocol classified as: **Bridge/Relayer** with **Meta-transaction** characteristics + +The contract functions as a relayer layer — accepting off-chain signed authorizations and forwarding token + call operations to a fixed destination. It shares bridge-like trust patterns (signature verification, relay mechanics, nonce tracking) combined with meta-transaction gasless execution via ERC-2612 permits. + +### Actors & Adversary Model + +| Actor | Trust Level | Capabilities | +|-------|-------------|-------------| +| Owner | Trusted | Can withdraw any ERC-20 tokens and native ETH from the contract. All operations instant — no timelock, no multisig. Ownership transferable via `Ownable.transferOwnership()` (single-step). | +| Relayer Bot | Bounded (can only submit valid signed payloads) | Submits `execute()` with user-signed permit + payload. Cannot forge signatures, but chooses gas price and timing. | +| User (Token Owner) | Bounded (signs permits and payloads) | Signs off-chain messages authorizing token spend + call forwarding. Nonce prevents replay. | + +**Adversary Ranking** (ordered by threat level): + +1. **Compromised Owner** — Single EOA controls all fund recovery functions with no delay; immediate drain of any tokens or ETH held by the contract. +2. **Signature replay / front-run attacker** — Observes signed permit + payload in mempool; can front-run the permit call (mitigated by try-catch) or attempt payload replay (mitigated by nonces). +3. **Malicious destination contract** — The immutable `destinationContract` receives arbitrary calls with forwarded ETH; if compromised or malicious, it could exploit the approval window or callback during `_forwardCall`. +4. **MEV searcher** — Can sandwich or front-run `execute()` transactions to extract value from the token transfer or forwarded call. + +See [entry-points.md](entry-points.md) for the full permissionless entry point map. + +### Trust Boundaries + +- **User → Relayer Bot**: User trusts the relayer bot to submit their signed messages faithfully and in a timely manner. The bot cannot modify signed data but controls submission timing and gas. No on-chain enforcement of submission obligation. +- **Relayer Contract → Destination Contract**: The relayer grants exact-amount approval then forwards arbitrary calldata. The destination is immutable (set at construction), but the forwarded call is fully user-defined. If the destination contract has exploitable functions, the relayer's approval window (between `forceApprove` and revoke) is the attack surface. +- **Owner → Contract Funds**: Owner has instant, unrestricted withdrawal of all assets. No timelock or multisig protects this boundary. A compromised owner key means total loss of contract-held funds. + +### Key Attack Surfaces + +- **Owner key compromise** — Owner can instantly drain all ERC-20 tokens via `withdrawToken()` and all ETH via `withdrawETH()`. No timelock, no multisig, no delay. Single-step ownership transfer via `Ownable.transferOwnership()` (no acceptance step required). This is the highest-impact attack surface for any funds held by the contract. + +- **Approval window during execute()** — Between `forceApprove(destination, value)` and `forceApprove(destination, 0)`, the destination contract has an active token approval. The `_forwardCall` makes a low-level `.call()` to the destination with arbitrary data during this window. If the destination contract can be made to call back into the token (or if the token has callbacks like ERC-777), the approval could be exploited. The `nonReentrant` guard on `execute()` mitigates re-entry into the relayer but does not prevent the destination from using the approval directly. + +- **Forwarded call data integrity** — The EIP-712 payload signature includes `destination` hardcoded to `destinationContract` in `_computeDigest`, `token`, `value`, `data`, `ethValue`, `nonce`, and `deadline`. The user signs over these fields, so the relayer bot cannot alter them. However, the `data` field is opaque — the contract does not validate what function is being called on the destination. Security depends entirely on the user understanding what they're signing. + +- **Permit front-running resilience** — The try-catch around `permit()` handles the case where an attacker front-runs the permit call. However, the fallback checks `allowance(owner, relayer) >= value` — if a previous permit set a higher allowance that was partially consumed, the check could pass with a stale allowance from a different context. The `safeTransferFrom` after the check ensures tokens are actually available. + +### Protocol-Type Concerns + +**As a Bridge/Relayer:** +- The `_forwardCall` uses a raw `.call()` without return data validation. Success is checked but return data is silently discarded (`(bool success, ) = ...`). If the destination returns meaningful error data, it's lost — `TokenRelayer:186-188`. +- Nonce management uses a per-user, per-nonce boolean mapping. There is no sequential nonce enforcement — nonces can be used in any order. This is by design (flexibility) but means a user cannot cancel a pending payload by incrementing their nonce; they must wait for expiry — `TokenRelayer:35`. + +**As a Meta-transaction system:** +- The EIP-712 domain is `("TokenRelayer", "1")` with automatic chain ID handling via OZ's `EIP712`. On a chain fork, the domain separator updates correctly, preventing cross-chain replay — `TokenRelayer:68`. +- The `payloadDeadline` and `deadline` (permit) are separate parameters. A user could sign a permit with a long deadline but a short payload deadline, leaving a dangling permit approval if the payload expires — `TokenRelayer:42-49`. + +### Temporal Risk Profile + +**Deployment & Initialization:** +- The `destinationContract` is set immutably in the constructor with a zero-address check. No initialization front-running risk — `TokenRelayer:66-72`. However, ownership is set to `msg.sender` (deployer). If ownership transfer to a multisig is intended but delayed, the single EOA controls all withdrawal functions in the interim. + +### Composability & Dependency Risks + +**Dependency Risk Map:** + +> **ERC-20 Token (arbitrary)** — via `TokenRelayer:execute()` +> - Assumes: Standard ERC-20 with ERC-2612 permit; `safeTransferFrom` handles non-standard return values +> - Validates: Uses SafeERC20 for transfers, try-catch for permit +> - Mutability: Depends on token — many ERC-20s (USDC, USDT) are upgradeable proxies +> - On failure: Permit failure falls back to allowance check; transfer failure reverts + +> **Destination Contract (immutable address)** — via `TokenRelayer:_forwardCall()` +> - Assumes: Accepts arbitrary calldata, returns success/failure +> - Validates: Checks bool success only; return data discarded +> - Mutability: Address is immutable, but if destination is a proxy, implementation can change +> - On failure: Reverts entire execute() transaction + +**Token Assumptions** (unvalidated): +- Fee-on-transfer tokens: `safeTransferFrom` transfers `value` but actual received amount may be less — the subsequent `forceApprove(destination, value)` would approve more than the contract holds, which is benign (destination can only take what's there), but accounting is imprecise +- Rebasing tokens: Balance could change between `safeTransferFrom` and `_forwardCall` — no internal accounting to detect this +- ERC-777 tokens: `tokensReceived` callback during `safeTransferFrom` could trigger reentrancy; `nonReentrant` on `execute()` mitigates this +- Blocklist tokens (USDC, USDT): If the relayer contract address is blocklisted, all operations involving that token will revert permanently + +--- + +## 3. Invariants + +### Stated Invariants + +- "Nonce used" — each `(owner, nonce)` pair can only be consumed once: `require(!usedPayloadNonces[owner][nonce], "Nonce used")` — `TokenRelayer:86` +- "Payload expired" — payload must be executed before deadline: `require(block.timestamp <= params.payloadDeadline, "Payload expired")` — `TokenRelayer:87` +- "Invalid sig" — ECDSA-recovered signer must match declared owner: `require(ECDSA.recover(digest, ...) == owner, "Invalid sig")` — `TokenRelayer:100` +- "Incorrect ETH value provided" — msg.value must exactly match signed payloadValue: `require(msg.value == params.payloadValue, "Incorrect ETH value provided")` — `TokenRelayer:102` + +### Inferred Invariants + +- **Zero residual approval**: After every successful `execute()`, the destination contract's allowance from the relayer is 0. Derived from `TokenRelayer:121,127` (`forceApprove(value)` then `forceApprove(0)`). If violated: destination retains ability to pull tokens from the relayer. +- **CEI ordering**: State changes (`usedPayloadNonces` update) happen before all external interactions.

Executive Summary +A comprehensive security review was conducted on the `TokenRelayer.sol` smart contract. The contract is designed to act as a secure intermediary that accepts ERC20 permit signatures alongside an EIP712 arbitrary payload signature, executing pre-approved calls to a designated immutable destination contract. + +**Conclusion:** The smart contract demonstrates exceptional adherence to modern Solidity security best practices and robustness. There are **no critical or high-severity vulnerabilities**. The architecture handles common pitfalls intelligently, particularly regarding strict token isolation, signature protection, and front-running resilience. + +--- + +## 2. Key Security Highlights & Best Practices Implemented + +* **Permit Front-Running Resilience:** The contract successfully neutralizes front-running Denial-of-Service (DoS) attacks on `permit`. By elegantly wrapping `permit` execution in a `try-catch` block, any malicious extraction of the permit into the mempool will simply trigger the fallback allowance check, allowing the primary payload to execute without disruption. +* **Strict Token Approval Isolation:** The relayer implements precise exposure bounds. Before forwarding the transaction to `destinationContract`, the relayer invokes `forceApprove` strictly for `params.token` bounded by `params.value`. This ensures that even if a malicious user invokes the relayer using fake ERC20 tokens, they cannot exploit residual balances of other tokens stuck inside the relayer's possession. +* **Immutable Destination Security:** `destinationContract` is hardcoded at deployment. This severely reduces the attack surface for arbitrary `_forwardCall` exploits since execution paths are statically restricted to one verified application. +* **Trapped Asset Protection:** `_forwardCall` inherently propagates exactly `msg.value` rather than indiscriminately pushing `address(this).balance`. Any un-withdrawn ETH residing in the relayer cannot be accidentally or maliciously weaponized. +* **Replay and Malleability Protections:** Utilizes OpenZeppelin’s `ECDSA.recover` to avoid signature malleability loopholes (rejecting high-S values). Implementing OpenZeppelin's `EIP712` correctly anchors execution to the deployed `chainId` and contract address, rendering cross-chain replays strictly impossible. + +--- + +## 3. Findings & Architectural Considerations (Low / Informational) + +### 3.1 Unspent Token Stranding (Informational) +**Description:** +When the relayer invokes `IERC20(params.token).safeTransferFrom` into `address(this)` and subsequently forces approval to the `destinationContract`, it assumes the destination contract will entirely consume `params.value`. If the `destinationContract` uses fewer tokens than deposited (e.g., executing a swap with a highly favorable slippage outcome), the unspent remainder tokens are stranded inside the `TokenRelayer` contract instead of automatically sweeping back to the user. + +**Risk/Impact:** +Users may experience a loss of their unspent excess unless the central operator sweeps via the `withdrawToken` administrative function sequentially to return them. + +**Recommendation:** +If `destinationContract` dynamics naturally lead to unpredictable leftover unspent balances, implement a local balance check on the relayer before and after execution to explicitly refund the unused token difference back to `params.owner`. + +### 3.2 Detached Permit Signature Arguments (Informational) +**Description:** +`params.permitV`, `params.permitR`, `params.permitS`, and `params.deadline` are executed outside the EIP712 payload digestive hashing. Let it be explicitly known that these parameters theoretically face on-chain mutation from MEV extraction bots intercepting the mempool. + +**Risk/Impact:** +Mutation of these values strictly disrupts the `try` block, subsequently failing the payload execution because no pre-existing allowance exists. The overarching payload logic cannot be altered, averting any financial vector escalation. + +**Recommendation:** +No immediate action is needed, but acknowledging their deliberate omission from the primary signature ensures accurate context for future upgrades. + +### 3.3 Single Hardcoded Destination Structure (Design Note) +**Description:** +Restricting calls strictly to a singular `destinationContract` offers spectacular lateral protection but inherently sacrifices composability if multiple operational destinations are anticipated in future versions. + +**Recommendation:** +Currently safe. If future designs require multiplexing multiple destinations, extreme caution regarding recursive call-bombing or arbitrary balance extraction must be enforced. + +--- + +## 4. Final Verdict +The `TokenRelayer.sol` contract introduces a highly secure and robust execution standard. The development exhibits sharp awareness of front-running patterns, safe external interactions, and proper standard protocol implementations (EIP-712 / EIP-2612). It is cleared for deployment and utilization.

A phase handler MUST NOT access presigned transactions for a different phase. +4. **Token amounts at each phase MUST be traceable to the original quote** — The quote defines input/output amounts. Each phase should operate on amounts derived from the quote, not from untrusted runtime state. +5. **Cross-chain transfers MUST wait for finalization before advancing** — XCM and bridge transfers must confirm the source chain has finalized the send before the destination chain phase begins. Non-finalized transfers can be reverted by chain reorganization. +6. **Fee distribution MUST happen after all user-facing phases complete** — The `distributeFees` phase occurs near the end of the flow. Deducting fees before the user receives their funds risks the ramp failing after fees are taken. +7. **Each phase handler MUST be idempotent or have re-execution guards** — If the phase processor retries a phase (due to timeout or recoverable error), the handler must not double-execute (double-swap, double-transfer, double-fund). Nonce checks and balance pre-checks serve this purpose. + +## Threat Vectors & Mitigations + +| Threat | Attack Scenario | Mitigation | +|---|---|---| +| **Phase skip / injection** | Attacker with DB access modifies `currentPhase` to skip subsidization or jump to `complete`. | Phase transitions are controlled by handler return values, not external input. DB access is a prerequisite (see `state-machine.md`, Threat: "Phase skip attack"). No DB-level constraints on valid transitions exist. | +| **Subsidy drain** | A crafted ramp triggers multiple subsidization phases, each at the maximum allowed amount, draining the funding account. | Per-ramp subsidy caps (`MAX_FINAL_SETTLEMENT_SUBSIDY_USD`, balance pre-checks in pre/post-swap handlers). No aggregate cross-ramp cap exists — many concurrent ramps could still drain funds. | +| **Double-execution on retry** | Phase processor retries after timeout. Handler re-executes a swap or transfer that already completed. Funds are consumed twice. | Nonce guards in Spacewalk and Hydration handlers detect prior execution. Other handlers rely on transaction nonce uniqueness at the chain level. Not all handlers have explicit re-execution guards. | +| **Stale presigned transaction** | Client registers a ramp, waits for market movement, then starts the ramp with presigned transactions based on the old quote. | `RAMP_START_EXPIRATION_TIME_SECONDS` limits the window between registration and start. Quote expiry (10 minutes) limits how old the amounts can be. | +| **Cross-chain race condition** | XCM transfer submitted but not finalized. Next phase on destination chain reads a zero balance. | Most XCM handlers use `waitForFinalization=true`. Exception: Hydration skips finalization (F-009, deferred). | +| **Fee distribution failure** | `distributeFees` fails, but ramp is already marked `complete`. Platform loses fee revenue. | `distributeFees` is a phase — if it fails, the ramp enters retry, not `complete`. However, if the ramp fails after user delivery but before fee distribution, fees may be lost. | + +## Audit Checklist + +- [x] Phase processor calls handlers in sequence via `phaseRegistry` lookup — no parallel execution or phase skipping in code +- [x] `getPresignedTransaction(state, phase)` filters by phase name — handlers cannot accidentally access another phase's transaction +- [x] `subsidize-pre-swap-handler` and `subsidize-post-swap-handler` both query funding account balance before transfer (after F-032 fix) +- [x] `final-settlement-subsidy` has `MAX_FINAL_SETTLEMENT_SUBSIDY_USD` cap (after F-001 fix) +- [x] `final-settlement-subsidy` validates SquidRouter swap output amount (after F-030 fix) +- [x] `squidrouter-permit-execution-handler` validates `squidRouterPermitExecutionValue` cap (after F-027 fix) +- [x] `spacewalk-redeem-handler` has nonce-based re-execution guard — skips to waiting path if nonce indicates prior execution +- [x] Hydration XCM handler has nonce guard but only warns (F-028, fixed to skip like Spacewalk) +- [x] Moonbeam handler refreshes gas estimate per retry attempt (F-028, fixed) +- [x] `post-swap-handler` has explicit default rejection for unrecognized routing combinations (F-031, fixed) +- [x] `distributeFees` is a non-terminal phase — failure triggers retry, not silent skip +- [ ] No aggregate cross-ramp subsidy rate limiting — many concurrent ramps could drain funding account +- [ ] Not all handlers have explicit idempotency guards (rely on chain-level nonce uniqueness) diff --git a/docs/security-spec/03-ramp-engine/transaction-validation.md b/docs/security-spec/03-ramp-engine/transaction-validation.md new file mode 100644 index 000000000..431fc2261 --- /dev/null +++ b/docs/security-spec/03-ramp-engine/transaction-validation.md @@ -0,0 +1,51 @@ +# Transaction Validation — Presigned Transaction Verification + +## What This Does + +Before a ramp begins execution, the client signs a set of transactions that the server will later submit on behalf of the user. This presigned transaction model is the core trust boundary of the ramp engine: the server MUST verify that every presigned transaction matches the expected parameters (recipient, amount, asset, chain, signer) before accepting and executing it. Without content-level validation, a malicious API client could submit transactions that redirect user funds, authorize unlimited token approvals, or target attacker-controlled addresses — all of which the server would faithfully execute. + +Validation occurs at two points: +1. **`updateRamp`** — When the client submits signed transactions, `validatePresignedTxs()` and `areAllTxsIncluded()` are called. +2. **`startRamp`** — Before execution begins, `validatePresignedTxs()` runs again, plus `validateAllPresignedTransactionsSigned()` confirms all expected transactions are signed. + +The validation logic lives in `apps/api/src/api/services/transactions/validation.ts` and is chain-specific: separate paths for EVM (Ethereum-compatible), Substrate (Polkadot-compatible), and Stellar transactions.

Metadata-only matching (phase+network+nonce+signer) is insufficient. +2. **EVM typed data (EIP-712) MUST be validated with the same rigor as raw transactions** — Permit signatures, SquidRouter executions, and any other EIP-712 signed data must have their structured fields (spender, value, deadline, target contract) verified against expected values. +3. **Stellar payment transactions MUST validate amount, destination, and asset** — A payment operation that passes the "is a payment" type check but sends to an attacker address or sends the wrong amount is equally dangerous. +4. **Stellar account setup transactions MUST validate startingBalance, cosigner in SetOptions, and ChangeTrust asset** — Each operation in the multi-operation setup XDR has security-critical parameters beyond just "correct operation type." +5. **Substrate extrinsic content MUST be decoded and validated** — Signer-only validation is insufficient. The extrinsic method, call parameters, amounts, and destination addresses must match expected values. +6. **SELL-direction SquidRouter transactions MUST NOT bypass validation** — Off-ramp swap/approve phases must be validated with the same rigor as BUY-direction phases. +7. **`areAllTxsIncluded` MUST match on transaction content, not only metadata** — Matching on phase+network+nonce+signer allows a client to substitute completely different transaction data while preserving the metadata envelope. +8. **No chain type or transaction format may be silently skipped during validation** — If a new chain or transaction format is added, the validator must either handle it or reject it. Silent pass-through (`return` without validation) is forbidden. +9. **Validation MUST occur before any presigned transaction is persisted or executed** — The `updateRamp` and `startRamp` flows must reject invalid transactions before merging them into ramp state. + +## Threat Vectors & Mitigations + +| Threat | Attack Scenario | Mitigation | +|---|---|---| +| **Fund redirection via Stellar payment** | Client signs a Stellar payment to an attacker address instead of the expected anchor deposit address.

All other ramp routes have zero auth middleware. - ---- - -#### 2. `[PASS]` `optionalAuth` is only used on endpoints where unauthenticated access is intentionally allowed - -`optionalAuth` is used on: -- `POST /v1/ramp/register` — registers a new ramp (pre-execution, before user has signed transactions). Intentional: userId is attached if available but not required. -- `POST /v1/quotes/` and `POST /v1/quotes/best` — quote creation is public by design (SDK/frontend creates quotes before auth). Intentional. -- `POST /v1/brla/createSubaccount`, `POST /v1/brla/getUploadUrls`, `POST /v1/brla/newKyc`, `POST /v1/brla/kyb/new-level-1/web-sdk`, `POST /v1/brla/kyc/record-attempt` — BRLA KYC operations where userId is optional for tracking. - -All these are reasonable uses of `optionalAuth`. However, several BRLA KYC endpoints arguably should use `requireAuth` since they create or modify user-specific resources (subaccounts, KYC records). This is a design question, not a strict violation. - ---- - -#### 3. `[FAIL]` `SupabaseAuthService.verifyToken()` uses the service role key, not the anon key - -**NEW FINDING — F-018.** - -At `supabase.service.ts:147`: -```typescript -const { data, error } = await supabase.auth.getUser(accessToken); -``` - -This uses the `supabase` client (created with `SUPABASE_ANON_KEY` at `config/supabase.ts:11`), **NOT** `supabaseAdmin` (created with `SUPABASE_SERVICE_KEY` at `config/supabase.ts:4`). - -**Analysis:** `supabase.auth.getUser(accessToken)` sends the access token to the Supabase REST API endpoint `/auth/v1/user`. The Supabase server verifies the JWT server-side regardless of which client key was used — the anon key identifies the project, while the access token itself is what gets verified. So this is **functionally equivalent** to using the admin client for token verification. - -However, the spec explicitly states "MUST use `SUPABASE_SERVICE_KEY`" and there's a subtle difference: with the anon key client, if Supabase's Row Level Security (RLS) policies interact with the verification call, the anon key's permissions apply. With the service role key, RLS is bypassed. For a pure `getUser()` call this doesn't matter, but it's a deviation from the spec's stated requirement. - -**Severity: 🔵 LOW** — Functionally correct (server-side verification happens regardless), but deviates from spec and best practice. Using `supabaseAdmin.auth.getUser(accessToken)` would be more explicit and immune to any future Supabase auth API behavior changes. - ---- - -#### 4. `[PASS]` The `Bearer ` prefix check uses `startsWith("Bearer ")` with the trailing space - -Confirmed at `supabaseAuth.ts:20`: -```typescript -if (!authHeader?.startsWith("Bearer ")) { -``` - -The trailing space after "Bearer" is present.

All auth verification calls will fail (network error), and `requireAuth` will correctly reject requests (fail closed). However, the service will appear to start normally — auth just silently stops working. - -**Severity: 🟡 MEDIUM** — The service starts and serves requests, but all authenticated endpoints silently become 401-only. No health check or startup log would indicate the misconfiguration. - -**Fix:** Add startup validation that terminates the process if any of the three Supabase config values are empty. - ---- - -#### 9. `[PASS]` Token expiry is enforced by the verification call - -`supabase.auth.getUser(accessToken)` sends the token to Supabase's server, which verifies both the signature and the expiration claim (`exp`). Expired tokens return an error, which results in `{ valid: false }` at `supabase.service.ts:149-151`. ✅ - -**Note:** This relies on Supabase's server-side behavior. If the anon-key client were somehow configured for local-only verification (it's not in the current Supabase JS SDK), expiry enforcement would depend on the JWT library.

This means the same key that holds and moves funds is also used for Stellar web authentication challenges. Spec invariant #1 says keys MUST only be used for their designated purpose. - -**Finding (NEW — F-022).** `SEP10_MASTER_SECRET` is aliased to `FUNDING_SECRET` rather than being an independent key. If the SEP-10 flow has a vulnerability that leaks key material, it directly compromises the funding account. The blast radius of a SEP-10 compromise is amplified from "authentication broken" to "funding account drained." - -**Severity: 🟡 MEDIUM** — SEP-10 challenge-response doesn't typically expose the signing key, but the principle of key separation is violated. - -**Fix:** Use a separate Stellar keypair for SEP-10 authentication (`SEP10_MASTER_SECRET` as its own env var). - -#### 2. `[PASS]` `PENDULUM_FUNDING_SEED` used only for funding ephemerals - -Used in: -- `subsidize.controller.ts:25` — `getFundingAccount()` creates a keyring pair for subsidization ✅ -- `pendulum.service.ts:19` — `fundEphemeralAccount()` funds ephemeral Pendulum accounts ✅ -- Phase handlers access it via these service functions, not directly - -Both uses are for funding/subsidization — the designated purpose. No arbitrary extrinsic signing. - -**Note:** Dual access paths persist (F-016 — `pendulum.service.ts:9` reads from `process.env` directly instead of through `constants.ts`). - -#### 3. `[PARTIAL]` `MOONBEAM_EXECUTOR_PRIVATE_KEY` purpose and aliasing - -`MOONBEAM_EXECUTOR_PRIVATE_KEY` is used directly for: -- Moonbeam XCM execution (`moonbeam.controller.ts:41,79`) ✅ -- Moonbeam→Pendulum handler (`moonbeam-to-pendulum-handler.ts:64`) ✅ -- SquidRouter permit execution (`squidrouter-permit-execution-handler.ts:107`) ✅ -- Monerium onramp self-transfer (`monerium-onramp-self-transfer-handler.ts:94`) ✅ - -Additionally, `MOONBEAM_FUNDING_PRIVATE_KEY = MOONBEAM_EXECUTOR_PRIVATE_KEY` (`constants.ts:45`) is used for: -- Fund ephemeral handler (`fund-ephemeral-handler.ts:327,362`) — EVM funding -- Final settlement subsidy (`final-settlement-subsidy.ts:61`) — SquidRouter swaps -- SquidRouter pay phase (`squid-router-pay-phase-handler.ts:59`) — SquidRouter payments -- Onramp transaction routes (`monerium-to-evm.ts:183`, `alfredpay-to-evm.ts:191`, `avenia-to-evm.ts:236`) -- Moonbeam balance/cleanup utilities (`balance.ts:13`, `cleanup.ts:12`) - -The executor and funder are the **same key** (intentional design — one account handles all EVM operations). All uses are platform operations — no user-level transactions. Spec says keys should have single purpose, but this is an intentional design decision where one EVM account handles all platform EVM operations. - -**Assessment:** PARTIAL. The key is used for its designated domain (all platform EVM operations on Moonbeam), but it serves both execution and funding roles. Not a new finding — document as an observation. - -#### 4. `[PASS]` `CryptoService.initializeKeys()` called exactly once at startup - -At `index.ts:54`: `cryptoService.initializeKeys()` is called once inside `initializeApp()`. The singleton pattern (`getInstance()`) ensures one `CryptoService` instance. `initializeKeys()` is not guarded against double-calls (it would overwrite), but it's only invoked once. - -#### 5. `[PASS]` `getPrivateKey()` is `private` - -At `crypto.ts:91`: `private getPrivateKey(): string`. Not accessible from outside the class. Only called internally by `signPayload()`. - -#### 6. `[PASS]` `getPublicKey()` is the only key-exposure method - -`CryptoService` has two public methods that deal with key material: -- `getPublicKey()` — Returns the RSA public key (PEM format) ✅ -- `signPayload()` — Uses the private key internally but returns a signature, not the key ✅ -- `verifySignature()` — Uses the public key ✅ - -No method returns the private key. - -#### 7. `[PASS]` Missing `WEBHOOK_PRIVATE_KEY` triggers warning log - -At `crypto.ts:43`: `logger.warn("RSA private key not found in environment, generating new key pair")`. This fires when the env var is absent and the service falls back to in-memory key generation. - -**Note:** The warning is logged, but the server continues running with an ephemeral key (existing finding F-011). - -#### 8. `[PASS]` RSA key generation uses 2048-bit modulus - -At `crypto.ts:57`: `modulusLength: 2048`. Confirmed. - -#### 9. `[PASS]` Signing uses RSA-PSS with SHA-256 and max salt - -At `crypto.ts:106-109`: -```typescript -crypto.sign("sha256", Buffer.from(payload, "utf8"), { - key: privateKey, - padding: crypto.constants.RSA_PKCS1_PSS_PADDING, - saltLength: crypto.constants.RSA_PSS_SALTLEN_MAX_SIGN -}); -``` -All three parameters confirmed: SHA-256 hash, PSS padding, maximum salt length. - -#### 10. `[PASS]` No server key appears in API responses, logs, or error messages - -Verified: -- `FUNDING_SECRET` → used to derive `FUNDING_PUBLIC_KEY` via `Keypair.fromSecret().publicKey()`, only the public key is exposed -- `MOONBEAM_EXECUTOR_PRIVATE_KEY` → used via `privateKeyToAccount()` which derives the address; only the address appears in transactions -- `PENDULUM_FUNDING_SEED` → used via `keyring.addFromUri()` which derives the account; only the address appears -- `WEBHOOK_PRIVATE_KEY` → only `getPublicKey()` is callable externally -- Error messages in `crypto.ts` are generic ("RSA key initialization failed", "Payload signing failed") — no key material - -No logging statements include key values. The `validateRequiredEnvVars()` function logs key names (e.g., `"FUNDING_SECRET not set"`) but not values. - -#### 11. `[PASS]` Server startup fails if mandatory keys are missing - -At `index.ts:31-45`, `validateRequiredEnvVars()` checks `FUNDING_SECRET`, `PENDULUM_FUNDING_SEED`, `MOONBEAM_EXECUTOR_PRIVATE_KEY`, and `CLIENT_DOMAIN_SECRET`. If any is falsy, it logs an error and calls `process.exit(1)`. - -**Note:** `WEBHOOK_PRIVATE_KEY` is NOT in this check (intentional — it has a fallback). `ADMIN_SECRET` and Supabase keys are also not checked (F-019 covers Supabase). - -#### 12. `[N/A]` Funding and executor accounts hold minimal balances - -This is an operational check — cannot be verified from code alone. Requires checking on-chain balances. The constants define bounded starting amounts for ephemerals (`2.5 XLM`, `0.1 PEN`, `1 GLMR`), but the actual funding account balance is a deployment concern. - -#### 13. `[N/A]` Monitoring/alerts for balance changes - -No monitoring or alerting infrastructure is present in the codebase. This is an operational concern. No code references to balance monitoring, PagerDuty, Slack alerts for balance thresholds, etc. (The Slack integration is for general notifications, not balance-specific alerts.) - -### Server-Side Signing Audit Summary - -| # | Checklist Item | Result | -|---|---|---| -| 1 | `FUNDING_SECRET` used only for its purpose | 🟡 PARTIAL — Also aliased as `SEP10_MASTER_SECRET` (F-022) | -| 2 | `PENDULUM_FUNDING_SEED` used only for funding | ✅ PASS (dual access path noted, F-016) | -| 3 | `MOONBEAM_EXECUTOR_PRIVATE_KEY` used only for platform ops | 🟡 PARTIAL — Also aliased as `MOONBEAM_FUNDING_PRIVATE_KEY` (intentional) | -| 4 | `initializeKeys()` called exactly once | ✅ PASS | -| 5 | `getPrivateKey()` is `private` | ✅ PASS | -| 6 | Only `getPublicKey()` exposes key material | ✅ PASS | -| 7 | Missing `WEBHOOK_PRIVATE_KEY` logs a warning | ✅ PASS | -| 8 | RSA 2048-bit modulus | ✅ PASS | -| 9 | RSA-PSS + SHA-256 + max salt | ✅ PASS | -| 10 | No server key in responses/logs/errors | ✅ PASS | -| 11 | Missing mandatory keys → startup failure | ✅ PASS | -| 12 | Minimal balances on funding/executor accounts | ❓ N/A — Operational check | -| 13 | Monitoring/alerts for balance changes | ❓ N/A — No monitoring infrastructure in code | - -### New Findings from Server-Side Signing Audit - -| ID | Severity | Summary | -|---|---|---| -| **F-022** | 🟡 MEDIUM | `SEP10_MASTER_SECRET` is aliased to `FUNDING_SECRET` — key purpose separation violated, amplifies blast radius of SEP-10 compromise | - ---- - -## 03 — Ramp Engine - -### 03a — State Machine (Phase Processor) - -**Spec:** `03-ramp-engine/state-machine.md` -**Source files reviewed:** `apps/api/src/api/services/phases/phase-processor.ts`, `apps/api/src/api/services/phases/phase-registry.ts`, `apps/api/src/api/services/phases/base-phase-handler.ts`, all 28+ phase handlers in `apps/api/src/api/services/phases/handlers/` - -#### 1. `[EXISTING FINDING]` Lock acquisition is non-atomic - -**Already tracked as F-003.** Confirmed in code at `phase-processor.ts:78-94`: - -```typescript -if (this.lockedRamps.has(state.id) || state.processingLock.locked) { - return false; -} -this.lockedRamps.add(state.id); -await RampState.update({ processingLock: { locked: true, lockedAt: new Date() } }, ...); -``` - -The check on `state.processingLock.locked` reads from a potentially stale `findByPk()` result. Between the check and the `RampState.update()`, another process could also read `locked: false` and acquire the lock. No `SELECT FOR UPDATE`, advisory lock, or atomic CAS operation is used. - ---- - -#### 2. `[EXISTING FINDING]` After max retries exhausted, ramp stays in current phase — infinite soft loop - -**Already tracked as F-004.** Confirmed at `phase-processor.ts:234-246`: - -```typescript -if (currentRetries < this.MAX_RETRIES) { - // ... retry logic -} -logger.error(`Max retries (${this.MAX_RETRIES}) reached for ramp ${errorUpdatedState.id}`); -this.retriesMap.delete(errorUpdatedState.id); -``` - -After max retries, the retries map is cleared and the method returns without transitioning to `failed`. On the next processing cycle, `retriesMap.get(state.id)` returns `undefined` → `currentRetries = 0` → retry counter effectively resets → the ramp is retried again indefinitely. - ---- - -#### 3. `[PASS]` `state.update()` in the processor uses `{ fields: ["currentPhase", "phaseHistory"] }` - -Confirmed at `phase-processor.ts:181-183`: - -```typescript -const updatedState = await state.update( - { currentPhase: pendingState.currentPhase, phaseHistory: pendingState.phaseHistory }, - { fields: ["currentPhase", "phaseHistory"] } -); -``` - -The `fields` array restricts the UPDATE to only these two columns, preventing accidental overwrite of other state columns during phase transitions. ✅ - ---- - -#### 4. `[PASS]` Terminal states `complete` and `failed` both trigger `retriesMap.delete()` and halt recursion - -Confirmed at `phase-processor.ts:199-208`: - -- `complete` → logs success, calls `this.retriesMap.delete(state.id)`, no recursive call ✅ -- `failed` → logs error, calls `this.retriesMap.delete(state.id)`, no recursive call ✅ -- Same phase (no change, non-terminal) → logs warning, calls `this.retriesMap.delete(state.id)`, no recursive call ✅ - -All branches clean up the retry counter. Only the phase-changed-to-non-terminal branch recurses. - ---- - -#### 5. `[PASS]` `MAX_EXECUTION_TIME_MS` (10 minutes) is enforced via `Promise.race` with a timeout promise - -Confirmed at `phase-processor.ts:166-176`: - -```typescript -const maxExecuteTime = this.MAX_EXECUTION_TIME_MS; // 10 * 60 * 1000 -const timeoutPromise = new Promise((_, reject) => { - timeoutId = setTimeout(() => { - reject(new RecoverablePhaseError("Phase execution timed out")); - }, maxExecuteTime); -}); -const pendingState = await Promise.race([handler.execute(state), timeoutPromise]).finally(() => { - clearTimeout(timeoutId); -}); -``` - -`Promise.race` ensures whichever resolves first wins. Timeout rejects with `RecoverablePhaseError`, which triggers the retry path. `clearTimeout` in `finally` prevents timer leaks. ✅ - ---- - -#### 6. `[PASS]` `MAX_RETRIES` (8) is the hard limit — no code path bypasses this - -`MAX_RETRIES = 8` at line 15. The retry gate at line 234: - -```typescript -if (currentRetries < this.MAX_RETRIES) { ... } -``` - -No other code path resets `currentRetries` during the retry loop. The only reset is `retriesMap.delete()` on terminal states or phase change. Within a single `processRamp()` call, the counter is monotonically increasing. - -**Caveat:** As noted in F-004, the counter resets across `processRamp()` calls because it's stored in an in-memory Map that gets deleted after max retries. - ---- - -#### 7. `[PASS]` `RecoverablePhaseError.minimumWaitSeconds` is respected when provided; fallback is 30 seconds - -Confirmed at `phase-processor.ts:213-214,237`: - -```typescript -const minimumWaitSeconds = - error instanceof RecoverablePhaseError ? (error as RecoverablePhaseError).minimumWaitSeconds : undefined; -// ... -const delayMs = minimumWaitSeconds ? minimumWaitSeconds * 1000 : 30 * 1000; -``` - -If the error provides `minimumWaitSeconds`, it's used. Otherwise, 30 seconds. ✅ - ---- - -#### 8. `[PASS]` `phaseHistory` is append-only — phase transitions add to the array, never truncate it - -Confirmed in `base-phase-handler.ts:99-106`: - -```typescript -const phaseHistory = [ - ...state.phaseHistory, - { metadata, phase: nextPhase, timestamp: new Date() } -]; -``` - -Spread operator creates a new array with all existing entries plus the new one. No code path removes or truncates history entries. ✅ - ---- - -#### 9. `[PASS]` Error logs include required fields - -Confirmed at `phase-processor.ts:220-230`: - -```typescript -{ - details: error.stack || "", // stack trace ✅ - error: error.message || "Unknown", // error message ✅ - isPhaseError, // phase error flag ✅ - phase: state.currentPhase, // phase name ✅ - recoverable: isRecoverable, // recoverability flag ✅ - timestamp: new Date().toISOString() // ISO timestamp ✅ -} -``` - -All required fields present. ✅ - ---- - -#### 10. `[PASS]` No phase handler directly calls `RampState.update()` for `currentPhase` - -Verified via grep: No handler in `apps/api/src/api/services/phases/handlers/` calls `state.update()` with `currentPhase` in the arguments. The static method `RampState.update()` is also not called by any handler. - -Handlers DO call `state.update()` for non-phase fields (e.g., `state.state`, transaction hashes, metadata), which is the expected pattern — handlers can update their own operational state, but phase transitions are exclusively controlled by the processor via `transitionToNextPhase()` → processor's `state.update({ currentPhase, phaseHistory })`. ✅ - ---- - -#### 11. `[PASS]` The `lockedRamps` Set is cleaned up in the `finally` block - -Confirmed at `phase-processor.ts:67-69`: - -```typescript -} finally { - await this.releaseLock(state); -} -``` - -And `releaseLock()` at line 103: `this.lockedRamps.delete(state.id)`.

F-003 (non-atomic lock) and F-004 (infinite soft loop) confirmed as previously documented. - ---- - -### 03b — Quote Lifecycle - -**Spec:** `03-ramp-engine/quote-lifecycle.md` -**Source files reviewed:** `apps/api/src/api/services/quote/` (full directory: orchestrator, finalize engines, discount engines, fee engines), `apps/api/src/api/services/ramp/ramp.service.ts` (quote consumption), `apps/api/src/api/services/ramp/base.service.ts` (`consumeQuote`, `isQuoteValid`), `apps/api/src/api/services/quote/engines/discount/helpers.ts` (dynamic pricing) - -#### 1. `[PASS]` Quote creation endpoint calculates all fee components server-side - -The quote pipeline flows through `QuoteOrchestrator.run()`, which executes stages: Initialize → NablaSwap → Fee → Discount → Finalize. All fee calculations happen in `BaseFeeEngine.execute()` which calls `calculateFeeComponents()` server-side. No fee amount is accepted from the client request. The `QuoteRequest` type accepts `inputAmount`, currencies, and direction — no fee parameters. ✅ - ---- - -#### 2. `[PASS]` Quote expiry is hardcoded to 10 minutes and cannot be overridden by client input - -Confirmed at two locations: - -- `finalize/index.ts:133`: `expiresAt: new Date(Date.now() + 10 * 60 * 1000)` (persisted flow) -- `finalize/index.ts:101`: `expiresAt: new Date(Date.now() + 10 * 60 * 1000)` (skip-persistence flow) - -The 10-minute duration is a hardcoded literal. No client parameter, env var, or database config controls it. ✅ - ---- - -#### 3. `[PASS]` `discountStateTimeoutMinutes` controls discount state inactivity, NOT quote expiry - -`discountStateTimeoutMinutes` is used exclusively in `discount/helpers.ts:22`: - -```typescript -function isWithinStateTimeout(timestamp: Date, now: Date): boolean { - return now.getTime() - timestamp.getTime() < config.quote.discountStateTimeoutMinutes * 60 * 1000; -} -``` - -This controls whether the partner's `difference` is adjusted on a new quote request. It has no relationship to `QuoteTicket.expiresAt`. The two timeouts are clearly separate mechanisms that happen to share the same default value (10 minutes). ✅ - ---- - -#### 4. `[PASS]` Quotes are marked as consumed atomically with ramp creation - -At `ramp.service.ts:96`, `registerRamp()` wraps the entire operation in `this.withTransaction()`: - -```typescript -return this.withTransaction(async transaction => { - const quote = await QuoteTicket.findByPk(quoteId, { transaction }); - // ... validation ... - await this.consumeQuote(quote.id, transaction); // line 134 - handleQuoteConsumptionForDiscountState(partner); // line 141 - const rampState = await this.createRampState(...); // line 144 - // ... -}); -``` - -`consumeQuote()` at `base.service.ts:116-124`: - -```typescript -return QuoteTicket.update( - { status: "consumed" }, - { returning: true, transaction, where: { id, status: "pending" } } -); -``` - -The `where: { status: "pending" }` clause ensures atomicity — if two concurrent registrations try to consume the same quote, only one will match `status: "pending"` and succeed. The other will update 0 rows. Both quote consumption and ramp creation share the same database transaction. ✅ - -**Note:** `handleQuoteConsumptionForDiscountState()` modifies in-memory state outside the transaction — if the transaction rolls back, the discount state adjustment is NOT reverted. This is a minor inconsistency (discount state could drift by one `deltaD` step on a failed registration), but low impact given the tiny step size (0.00003). - ---- - -#### 5. `[PASS]` `deltaDBasisPoints` (default 0.3) step size - -At `discount/helpers.ts:17-19`: - -```typescript -function getDeltaD(): Big { - return new Big(config.quote.deltaDBasisPoints).div(10000); -} -``` - -With default `deltaDBasisPoints = 0.3`: `0.3 / 10000 = 0.00003` per step. This is a very small adjustment — 0.003% per step. With a 10-minute timeout between steps, it would take over 5 hours of continuous quoting to accumulate a 0.01% rate change. Reasonable granularity. ✅ - ---- - -#### 6. `[N/A]` `maxDynamicDifference` and `minDynamicDifference` values for all partners - -These are database values that cannot be verified from code alone. The code correctly reads them from `Partner.findOne()` and applies them as caps. Database content review is needed. - ---- - -#### 7. `[EXISTING FINDING]` Dynamic pricing state is in-memory only - -**Already tracked as F-012.** Confirmed: `partnerDiscountState` at `discount/helpers.ts:15`: - -```typescript -const partnerDiscountState = new Map(); -``` - -Module-level variable, no persistence, no serialization to DB or file. Lost on restart. - ---- - -#### 8. `[N/A]` `minDynamicDifference` cannot be set to a dangerously negative value - -No DB CHECK constraint in the code. The `Partner` model would need to be inspected for constraints — this is a database schema/migration check. The code correctly applies the value as a lower bound via `Big.lt(minCap)` clamping at `helpers.ts:147`. - ---- - -#### 9. `[N/A]` `maxDynamicDifference` cannot be set to an unreasonably high value - -Same as above — database constraint check needed. The code correctly clamps at `helpers.ts:119`. - ---- - -#### 10. `[PASS]` Exchange rates used in quote calculation come from live on-chain sources - -The Nabla swap engine queries the DEX directly for actual swap rates. The discount engine uses `oraclePrice` which comes from the Nabla oracle (on-chain). Squid Router queries are live. Price feed service is used for fee currency conversions (less critical). The core swap rate is on-chain derived. ✅ - ---- - -#### 11. `[PASS]` Quote response does not include internal implementation details - -`buildQuoteResponse()` at `finalize/index.ts:20-58` returns a `QuoteResponse` with only: amounts, currencies, fee breakdown, dates, and IDs. The `adjustedDifference`, `adjustedTargetDiscount`, and `subsidyAmountInOutputTokenDecimal` are stored in `metadata` (the full `QuoteContext`) in the database but are NOT included in the API response. - -The `QuoteResponse` type does not expose any discount internals. ✅ - -**Note:** The full `QuoteContext` stored as `metadata` in the DB includes discount state. If an admin endpoint or debugging tool exposes raw `QuoteTicket` records, these values would be visible. But no current endpoint does this. - ---- - -#### 12. `[PASS]` Quote amounts (input, output, fees) are immutable once stored — no UPDATE endpoint modifies them - -Only two UPDATE operations exist on `QuoteTicket`: -- `consumeQuote()`: Updates only `status` to `"consumed"` ✅ -- `quote.destroy()` in `registerRamp()` for expired quotes ✅ - -No endpoint or service modifies `inputAmount`, `outputAmount`, or fee fields after creation. ✅ - ---- - -#### 13. `[PARTIAL]` Authentication is enforced on quote creation - -Quote routes at `quote.route.ts` use `optionalAuth` and `validatePublicKey` (with `apiKeyAuth({ required: false })`). This means: -- Quotes can be created without any authentication ✅ (by design — SDK creates quotes before user login) -- If a public API key is provided, it's validated and the partner is identified -- No `requireAuth` on quote creation - -This is intentional by design — quotes are semi-public to enable the SDK flow. Marked as PARTIAL because the spec says "verify which auth mechanisms protect quote creation." The answer is: optional auth + optional API key validation. - ---- - -#### 14. `[PARTIAL]` Quote ownership is verified at ramp registration - -At `ramp.service.ts:99-106`, the quote is looked up by ID. There is no check that the quote's `userId` or `partnerId` matches the requesting user/partner. Any caller with a valid quote ID can bind it to a ramp. - -However, the quote ID is a UUID generated server-side and not predictable. An attacker would need to know or guess a valid, non-expired, non-consumed quote ID. Combined with the 10-minute expiry and single-use consumption, the practical risk is low. - -**Assessment:** No strict ownership enforcement, but defense in depth from UUID unpredictability + expiry + single-use. Not a new finding — this is a design decision consistent with the SDK model where the same client creates the quote and registers the ramp. - ---- - -#### 15. `[PASS]` Subsidy is only calculated when `targetDiscount > 0` - -Confirmed in both discount engines: - -`offramp.ts:76-79`: -```typescript -const actualSubsidyAmountDecimal = - targetDiscount > 0 - ? calculateSubsidyAmount(adjustedExpectedOutputDecimal, actualOutputAmountDecimal, maxSubsidy) - : Big(0); -``` - -Identical pattern in `onramp.ts`. When `targetDiscount` is 0, subsidy is always 0 regardless of shortfall. ✅ - ---- - -#### 16. `[PASS]` `calculateSubsidyAmount` correctly caps at `maxSubsidy × expectedOutput` - -At `discount/helpers.ts:152-167`: - -```typescript -const maxAllowedSubsidy = expectedOutput.mul(maxSubsidyBig); -return shortfall.gt(maxAllowedSubsidy) ? maxAllowedSubsidy : shortfall; -``` - -`maxSubsidy` is treated as a fraction of `expectedOutput` (e.g., `maxSubsidy = 0.02` means cap at 2% of expected output). The multiplication semantics are correct. ✅ - ---- - -#### 17. `[PASS]` `resolveDiscountPartner` fallback to "vortex" default partner - -At `discount/helpers.ts:36-63`: - -```typescript -if (partnerId) { - const partner = await Partner.findOne({ where: { ...where, id: partnerId } }); - if (partner) return partner; -} -return Partner.findOne({ where: { ...where, name: DEFAULT_PARTNER_NAME } }); // "vortex" -``` - -Falls back to `"vortex"` when no `partnerId` is provided or when the provided partner is not found. This is intentional — all quotes get at least the default partner config. ✅ - ---- - -#### 18. `[N/A]` Monitoring exists for quotes with unusually high subsidization requirements - -No monitoring or alerting infrastructure for subsidization exists in the codebase. This is an operational gap, not a code finding. The subsidy amounts are logged and stored in the `Subsidy` database table, but no automated alerts fire on unusual values. - ---- - -### Quote Lifecycle Audit Summary - -| # | Checklist Item | Result | -|---|---|---| -| 1 | Fees calculated server-side, no client override | ✅ PASS | -| 2 | Quote expiry hardcoded to 10 min | ✅ PASS | -| 3 | `discountStateTimeoutMinutes` ≠ quote expiry | ✅ PASS | -| 4 | Quote consumed atomically with ramp creation | ✅ PASS | -| 5 | `deltaDBasisPoints` step size reasonable | ✅ PASS | -| 6 | Dynamic difference caps set to reasonable values | ❓ N/A — DB check | -| 7 | Dynamic pricing state in-memory only | ⚠️ EXISTING F-012 | -| 8 | `minDynamicDifference` DB constraint | ❓ N/A — DB check | -| 9 | `maxDynamicDifference` DB constraint | ❓ N/A — DB check | -| 10 | Exchange rates from live on-chain sources | ✅ PASS | -| 11 | Quote response doesn't leak discount internals | ✅ PASS | -| 12 | Quote amounts immutable after creation | ✅ PASS | -| 13 | Authentication on quote creation | 🟡 PARTIAL — Optional by design | -| 14 | Quote ownership verified at registration | 🟡 PARTIAL — No strict check, mitigated by UUID + expiry | -| 15 | Subsidy only when `targetDiscount > 0` | ✅ PASS | -| 16 | `calculateSubsidyAmount` cap correct | ✅ PASS | -| 17 | `resolveDiscountPartner` fallback to "vortex" | ✅ PASS | -| 18 | Monitoring for high subsidization | ❓ N/A — No monitoring infrastructure | - -### New Findings from Quote Lifecycle Audit - -No new findings. F-012 (in-memory discount state) confirmed. The `handleQuoteConsumptionForDiscountState()` not being transaction-aware is noted as an observation but not a standalone finding (impact: at most 0.003% rate drift per failed registration). - ---- - -### 03c — Fee Integrity - -**Spec:** `03-ramp-engine/fee-integrity.md` -**Source files reviewed:** `apps/api/src/api/services/quote/core/quote-fees.ts` (database fee calculation), `apps/api/src/api/services/quote/engines/fee/index.ts` (fee engine base), `apps/api/src/api/services/quote/engines/fee/*.ts` (per-route fee engines), `apps/api/src/api/services/quote/engines/finalize/index.ts`, `apps/api/src/api/services/phases/handlers/distribute-fees-handler.ts` - -#### 1. `[EXISTING FINDING]` Dual fee system discrepancy - -**Already tracked as F-002 (🔴 CRITICAL).** Confirmed by code analysis: - -**Path 1 — Database-based fees (DISPLAYED):** `calculateFeeComponents()` in `quote-fees.ts` computes fees from `Partner` and `Anchor` database tables. These are stored in `QuoteTicket.metadata.fees` and returned in the API response as `vortexFee`, `anchorFee`, `networkFee`, `partnerFee`. - -**Path 2 — Token-config-based fees (ACTUALLY DEDUCTED):** The actual amount the user receives is determined by the `computeOutput()` method in each finalize engine, which applies fees from `getAnyFiatTokenDetails()` (token config). These use `onrampFeesBasisPoints`, `offrampFeesBasisPoints`, and fixed components. - -The two paths calculate fees independently. The only thing unifying them is that both are computed during the same quote pipeline execution, but there's no reconciliation check that compares the two results or alerts on divergence. - -**Update from deeper analysis:** The fee engine now computes fees into `ctx.fees` which is stored in the quote. The finalize engine uses its own `computeOutput()` to determine the actual output. Both are stored but applied differently — `ctx.fees` is displayed, `computeOutput()` determines the output amount. The architectural intent appears to be transitioning toward a unified model, but the transition is incomplete. - ---- - -#### 2. `[PASS]` All fee calculations use `Big.js`, never native `number` - -All fee computation in `quote-fees.ts`, `discount/helpers.ts`, `fee/index.ts`, and finalize engines uses `Big` from `big.js`. Monetary amounts are represented as `Big` or `string` (to preserve precision). The only use of native `number` is for configuration values (`markupValue`, `targetDiscount`) which are used as `Big` inputs. No arithmetic on monetary amounts uses native JS `number`. ✅ - ---- - -#### 3. `[PASS]` Negative output protection - -In both finalize engines, the output is computed and validated. The `BaseFinalizeEngine.validate()` method can be overridden to check for negative outputs. The `Big.toFixed()` with round-down mode (mode 0) cannot produce negative results from a positive computation. - -Additionally, the fee engines themselves don't subtract fees from amounts — they calculate fee values and store them. The output amount in the finalize engine is calculated independently from the swap result and discount engine, which already handles the subsidy logic that prevents the user from receiving less than quoted. - ---- - -#### 4. `[PASS]` No fee parameter is accepted from the client request body - -The `QuoteRequest` type (from the quote pipeline) accepts: `inputAmount`, `inputCurrency`, `outputCurrency`, `rampType`, `from`, `to`, `network`, `countryCode`, `apiKey`, `userId`, `partnerId`. No fee rate, fee amount, or fee override field exists. All fee parameters come from server-side configuration (token config or database). ✅ - ---- - -#### 5. `[N/A]` Fee configuration from token configs matches what's intended for each currency - -This requires reviewing the actual values in `shared/src/tokens/*/config.ts` and comparing with intended fee schedules. The code correctly reads and applies these values, but the values themselves need business review. - ---- - -#### 6. `[PASS]` `distributeFees` phase distributes using pre-signed transactions - -At `distribute-fees-handler.ts:80`: - -```typescript -const distributeFeeTransaction = this.getPresignedTransaction(state, "distributeFees"); -``` - -The fee distribution uses a pre-signed transaction that was created during ramp registration (in `prepareRampTransactions()`), which uses the quote's fee breakdown to compute exact transfer amounts. The handler submits this pre-signed transaction as-is — it doesn't recalculate fees at execution time. ✅ - -**Note:** If fees were to change between quote creation and fee distribution, the pre-signed transaction still uses the original amounts from the quote. This is correct behavior — fees are locked at quote time. - ---- - -#### 7. `[N/A]` Anchor fee deduction by external services is pre-accounted in the quoted amount - -This requires reviewing each integration-specific finalize engine (BRLA, Stellar, Monerium) to verify they account for anchor fees. The off-ramp discount engine does adjust for anchor fees: - -```typescript -const anchorFeeInBrl = ctx.fees?.displayFiat?.anchor ? new Big(ctx.fees.displayFiat.anchor) : new Big(0); -const adjustedExpectedOutputDecimal = oracleExpectedOutputDecimal.plus(anchorFeeInBrl); -``` - -This suggests the system adds the anchor fee back to the expected output before calculating subsidy, ensuring the subsidy covers the anchor fee impact. However, full verification requires tracing each integration path — deferred to Module 05 (Integrations). - ---- - -#### 8. `[PASS]` Fee changes in token config or database don't retroactively affect already-created quotes - -Quotes store their fee breakdown in `metadata.fees` (in the `QuoteTicket` table) at creation time. The ramp uses the quote's stored values. The `distributeFees` phase uses a pre-signed transaction from registration time. No code path re-fetches fee configuration during ramp execution. Changes to `Partner`, `Anchor`, or token config only affect new quotes. ✅ - ---- - -### Fee Integrity Audit Summary - -| # | Checklist Item | Result | -|---|---|---| -| 1 | Dual fee system discrepancy | 🔴 EXISTING F-002 | -| 2 | All fee calculations use `Big.js` | ✅ PASS | -| 3 | Negative output protection | ✅ PASS | -| 4 | No client-controlled fee parameters | ✅ PASS | -| 5 | Fee config values match intentions | ❓ N/A — Business review | -| 6 | `distributeFees` uses pre-signed transactions (locked at quote time) | ✅ PASS | -| 7 | Anchor fees pre-accounted in quoted amount | ↗️ Deferred to Module 05 | -| 8 | Fee changes don't affect in-flight ramps | ✅ PASS | - -### New Findings from Fee Integrity Audit - -No new findings.

However, the actual Solidity contract is not in this repo — it's deployed at `MOONBEAM_RECEIVER_CONTRACT_ADDRESS = 0x2AB52086e8edaB28193172209407FF9df1103CDc`. **We cannot verify from the application code alone whether the contract has an `onlyExecutor` modifier or equivalent.** The on-chain contract source needs separate verification. The app-side code correctly uses only the executor key to call it, but if the contract lacks access control, anyone could call `executeXCM`. - -**Check 6 — Pendulum→Moonbeam 3-tier recovery:** ✅ PASS. `pendulum-to-moonbeam-xcm-handler.ts` implements recovery in this exact order: -1. **Hash check (lines 102-118):** If `state.state.pendulumToMoonbeamXcmHash` exists, it checks if tokens arrived on Moonbeam. If yes, transitions. If not, waits with 2-min timeout. -2. **Token departure check (lines 121-136):** If `didTokensLeavePendulum()` returns true, the handler logs that XCM was likely submitted but hash wasn't stored, then waits for Moonbeam arrival. -3. **Fresh submit (lines 138-166):** Only if neither condition is met does the handler decode the presigned extrinsic and submit it via `submitXTokens`. The hash is stored immediately after submission (lines 157-161) to minimize the crash window. - -**Check 7 — Moonbeam balance polling with 2-min timeout:** ✅ PASS. `waitForMoonbeamArrival` (lines 88-99) uses `timeoutMs = 120000` (2 minutes) and polls every 5000ms. On timeout, it returns `false`, and the caller throws `this.createRecoverableError(...)`. - -**Check 8 — Hydration→AssetHub skips finalization:** ✅ PASS. Line 36: `await submitExtrinsic(xcmExtrinsic, hydrationNode.api, false)` — the third parameter `false` disables finalization wait. The comment on line 35 explains: "Don't wait for finalization because it somehow doesn't work on Hydration." This is an accepted risk per the spec. - -**Check 9 — Hydration nonce re-execution guard:** ⚠️ PARTIAL. Lines 26-32 of `hydration-to-assethub-xcm-phase-handler.ts`: -```ts -const currentEphemeralAccountNonce = accountData.nonce.toNumber(); -if (currentEphemeralAccountNonce !== undefined && currentEphemeralAccountNonce > nonce) { - logger.warn(`Nonce mismatch: ...`); -} -``` -**ISSUE:** The nonce check only logs a warning — it does NOT skip re-submission or transition to `complete`. The spec says "if `currentNonce > executeNonce`, the handler skips re-submission and transitions directly to `complete`." The code continues to submit the extrinsic regardless. This means if a crash occurs after the XCM was sent but before the phase transition, the retry will attempt to re-submit with a stale nonce. The Substrate runtime will likely reject it (nonce too low), causing the error path to be triggered. While not a double-execution risk (the chain rejects stale nonces), it's unnecessary error churn and doesn't match the spec's intent. **→ F-028** - -**Check 10 — Hydration swap uses presigned extrinsic:** ✅ PASS. Line 24: `this.getPresignedTransaction(state, "hydrationSwap")`. Line 26: `decodeSubmittableExtrinsic(hydrationSwap as string, hydrationNode.api)`. Line 27: `submitExtrinsic(swapExtrinsic, hydrationNode.api)`. No runtime construction of swap parameters. - -**Check 11 — Pendulum→AssetHub transitions to `complete`:** ✅ PASS. Line 38: `return this.transitionToNextPhase(state, "complete")`. - -**Check 12 — Pendulum→Hydration waits for balance:** ✅ PASS. Lines 37-49 define `didInputTokenArriveOnHydration()` which checks Hydration balance for the swap input asset. Line 68: `await waitUntilTrue(didInputTokenArriveOnHydration, 60000)` waits with a 60-second timeout. On success, transitions to `"hydrationSwap"`. - -**Check 13 — No XCM handler logs private keys:** ✅ PASS. Confirmed via grep — no handler logs `MOONBEAM_EXECUTOR_PRIVATE_KEY`, `PENDULUM_FUNDING_SEED`, or any private key material. Only addresses, transaction hashes, and balances are logged. - -**Check 14 — Moonbeam→Pendulum blind retry budget isolation:** ⚠️ PARTIAL. In `moonbeam-to-pendulum-handler.ts`, lines 109-126, the retry loop runs up to 5 attempts with 20-second delays. Each invocation of `executePhase` is one attempt from the phase processor's perspective. However, the 5-attempt loop is INSIDE a single `executePhase` call, meaning one phase processor attempt = up to 5 contract calls. The spec asks whether this "does not consume the phase processor's retry budget." **It does not directly consume it** — the phase processor sees one attempt regardless of how many retries happen internally. But if all 5 fail, the error propagates, and the phase processor will invoke `executePhase` again with its own retry budget, leading to 5 × N total contract calls where N = phase processor retries. This is the expected behavior per the spec's threat analysis (5 × 8 = 40 max), but worth noting. Additionally, `maxFeePerGas` and `maxPriorityFeePerGas` are estimated once (line 105) before the loop and reused across all 5 attempts — if gas prices change during the 100-second window, later attempts may underprice. **→ F-028 (combined with nonce issue)** - -### Checklist Summary — XCM Transfers - -| # | Check | Result | -|---|---|---| -| 1 | RPC shuffling persistence | ✅ PASS | -| 2 | 30min RecoverablePhaseError | ✅ PASS | -| 3 | Hash registration before executeXCM | ✅ PASS | -| 4 | Executor key not logged | ✅ PASS | -| 5 | On-chain caller validation | ⚠️ PARTIAL — cannot verify from app code | -| 6 | 3-tier recovery | ✅ PASS | -| 7 | 2-min Moonbeam balance timeout | ✅ PASS | -| 8 | Hydration finalization skip | ✅ PASS — accepted risk | -| 9 | Hydration nonce guard | 🔴 FAIL — F-028 (warning-only, no skip) | -| 10 | Hydration swap presigned | ✅ PASS | -| 11 | Pendulum→AssetHub terminal phase | ✅ PASS | -| 12 | Pendulum→Hydration balance wait | ✅ PASS | -| 13 | No private key logging | ✅ PASS | -| 14 | Retry budget isolation | ⚠️ PARTIAL — stale gas price across retries | - ---- - -### 6.2 Bridge Security — Spacewalk - -#### Checklist Results - -| # | Check | Result | -|---|---|---| -| 1 | `createVaultService()` filters by both `assetCode` AND `assetIssuer` | ✅ PASS | -| 2 | Vault capacity check before selection | ✅ PASS | -| 3 | Redeem extrinsic decoded from presigned data | ✅ PASS | -| 4 | Nonce guard identifies prior execution | ✅ PASS | -| 5 | `AmountExceedsUserBalance` catch does NOT re-submit | ✅ PASS | -| 6 | `isStellarEphemeralFunded()` checks existence AND trustline | ✅ PASS | -| 7 | 10-minute balance polling timeout | ✅ PASS | -| 8 | No fallback to default vault on failure | ✅ PASS | -| 9 | Vault slash/cancel mechanism documented | ⚠️ PARTIAL — documented in spec, no operational runbook | -| 10 | `@ts-ignore` on `.nonce.toNumber()` | 🟡 EXISTING FINDING — F-026 | -| 11 | Spacewalk maximum redeem amount per vault | ⚠️ PARTIAL — not validated in app code | -| 12 | No claimable-balance recovery mechanism | ✅ PASS — confirmed absent, documented as gap | - -#### Detailed Analysis - -**Check 1 — Vault filtering by both `assetCode` AND `assetIssuer`:** ✅ PASS. `getVaults.ts` lines 31-39: `getVaultsForCurrency()` filters vaults with both conditions: -- `vault.id.currencies.wrapped.asStellar.asAlphaNum4.code.toString() === assetCodeHex` -- `vault.id.currencies.wrapped.asStellar.asAlphaNum4.issuer.toString() === assetIssuerHex` -Both are AND-ed in the filter predicate along with `vaultHasEnoughRedeemable()`. - -**Check 2 — Capacity check before selection:** ✅ PASS. The `vaultHasEnoughRedeemable()` function (lines 14-20) calculates `redeemableTokens = issuedTokens - toBeRedeemedTokens` and verifies it's greater than `redeemableAmount`. This is part of the filter in `getVaultsForCurrency()`, so only vaults with sufficient capacity are returned. `createVaultService()` then takes `vaultsForCurrency[0]`. - -**Check 3 — Redeem extrinsic from presigned data:** ✅ PASS. `spacewalk-redeem-handler.ts` line 64: `this.getPresignedTransaction(state, "spacewalkRedeem")`. Line 93: `decodeSubmittableExtrinsic(spacewalkRedeemTransaction, pendulumNode.api)`. Line 94: `vaultService.submitRedeem(substrateEphemeralAddress, redeemExtrinsic)`.

If true, it logs "Recovery mode: Redeem already performed" and calls `waitForOutputTokensToArriveOnStellar()` followed by transitioning to `"stellarPayment"`. No re-submission occurs. - -**Check 6 — `isStellarEphemeralFunded()` checks existence AND trustline:** ✅ PASS. Already verified in Module 05 audit. The function checks both account existence on Stellar and the presence of the required trustline. In `spacewalk-redeem-handler.ts` line 49, it's called with `stellarTarget.stellarTokenDetails` which provides the asset details for trustline verification. - -**Check 7 — 10-minute polling timeout:** ✅ PASS.

Line 134: `checkBalancePeriodically(targetAccount, stellarAssetCode, amountUnitsBig, stellarPollingTimeMs, maxWaitingTimeMs)`. On timeout, throws "Stellar balance did not arrive on time" (line 137). - -**Check 8 — No fallback vault:** ✅ PASS. `createVaultService()` selects `vaultsForCurrency[0]` and constructs a `VaultService` bound to that single vault. The `submitRedeem` method uses `this.vaultId` only. If the selected vault fails, the error propagates up to the handler's catch block and ultimately to the phase processor — no alternative vault is tried within the same execution. - -**Check 9 — Vault slash/cancel documentation:** ⚠️ PARTIAL. The spec's Threat Vectors section documents the vault collateral slash mechanism. However, there is no operational runbook referenced in the codebase. The slash/cancel is a Spacewalk protocol mechanism that operates independently of Vortex code, but operations teams should know how to invoke cancel-redeem if needed. - -**Check 10 — `@ts-ignore` on `.nonce.toNumber()`:** 🟡 EXISTING FINDING (F-026). Same pattern as identified in Module 05. Line 72: `// @ts-ignore` before `accountData.nonce.toNumber()`. - -**Check 11 — Spacewalk max redeem per vault per tx:** ⚠️ PARTIAL. The app code checks vault capacity via `vaultHasEnoughRedeemable()` which compares `issuedTokens - toBeRedeemedTokens > redeemableAmount`. However, this is Vortex's check based on chain state. Whether Spacewalk itself enforces a per-transaction maximum (separate from available capacity) is a protocol-level question not verifiable from the app code. No explicit per-tx maximum check exists in the Vortex code. - -**Check 12 — No claimable-balance recovery:** ✅ PASS (confirming absence as known gap). The `isStellarEphemeralFunded()` pre-check prevents this scenario, but if bypassed, there is no recovery mechanism. No code path handles claimable balances. This is documented in the spec as a known operational gap. - -### Checklist Summary — Bridge Security - -| # | Check | Result | -|---|---|---| -| 1 | Vault filters by code AND issuer | ✅ PASS | -| 2 | Capacity check before selection | ✅ PASS | -| 3 | Presigned redeem extrinsic | ✅ PASS | -| 4 | Nonce guard skips re-submission | ✅ PASS | -| 5 | `AmountExceedsUserBalance` → wait only | ✅ PASS | -| 6 | Stellar funded check (existence + trustline) | ✅ PASS | -| 7 | 10-minute balance timeout | ✅ PASS | -| 8 | No fallback vault | ✅ PASS | -| 9 | Slash/cancel documented | ⚠️ PARTIAL — no operational runbook | -| 10 | `@ts-ignore` on nonce | 🟡 EXISTING — F-026 | -| 11 | Per-vault tx maximum | ⚠️ PARTIAL — not verified at protocol level | -| 12 | No claimable-balance recovery | ✅ PASS — confirmed absent | - ---- - -### 6.3 Fund Routing — Subsidization & Settlement - -#### Checklist Results - -| # | Check | Result | -|---|---|---| -| 1 | **CRITICAL**: `final-settlement-subsidy.ts` lines 210-213 missing `throw` | 🔴 EXISTING FINDING — F-001 (CRITICAL, still unfixed) | -| 2 | `subsidize-pre-swap-handler.ts` calculates `expected - current` | ✅ PASS | -| 3 | `subsidize-post-swap-handler.ts` calculates subsidy the same way | ✅ PASS | -| 4 | Both handlers skip when `currentBalance >= expectedAmount` | ✅ PASS | -| 5 | `getFundingAccount()` derives from `PENDULUM_FUNDING_SEED` | ✅ PASS | -| 6 | `MOONBEAM_FUNDING_PRIVATE_KEY` used only for EVM subsidization | 🔴 FAIL — F-029 | -| 7 | `destination-transfer-handler.ts` checks balance before submission | ✅ PASS | -| 8 | Presigned destination transfer submitted as-is | ✅ PASS | -| 9 | `final-settlement-subsidy.ts` SquidRouter swap input bounded | ⚠️ PARTIAL — bounded by rate calc but cap enforcement broken (F-001) | -| 10 | 5-attempt retry does not retry on malicious route indicators | 🔴 FAIL — F-030 | -| 11 | `subsidize-post-swap-handler.ts` next-phase routing covers all cases | ⚠️ PARTIAL — F-031 | -| 12 | Funding account balance checked before subsidization | 🔴 FAIL — F-032 | -| 13 | Monitoring/alerting on funding account balance | 🔵 N/A — operational concern, no code evidence | -| 14 | `MAX_FINAL_SETTLEMENT_SUBSIDY_USD` value reasonable | ✅ PASS | - -#### Detailed Analysis - -**Check 1 — F-001 CRITICAL (missing `throw`):** 🔴 EXISTING FINDING (F-001).

The swap amount is calculated from the subsidy shortfall (line 196: `subsidyAmountRaw.div(rate).mul(1.1).toFixed(0)` — the 1.1x buffer accounts for slippage). The amount is then checked against `MAX_FINAL_SETTLEMENT_SUBSIDY_USD` (lines 210-213). However, as established in F-001, the cap check doesn't actually throw, so the swap input is effectively unbounded. The rate-based calculation provides some natural bounding (it's derived from the subsidy shortfall), but without the cap enforcement, a manipulated price feed or extreme shortfall could result in an excessive swap. - -**Check 10 — Retry loop on malicious route:** 🔴 FAIL. The 5-attempt retry loop in `final-settlement-subsidy.ts` (lines 276-309) retries any transaction failure regardless of the cause. Specifically: -- Lines 276-309 retry if `receipt.status !== "success"` — this catches all failures including reverts from bad routes. -- There is no check on the swap output (e.g., "did we receive at least X% of expected tokens?"). -- If the SquidRouter API returns a consistently malicious route (draining native tokens to an attacker address), all 5 attempts would execute the same bad route. -- The swap route is fetched once (lines 216-233) and reused across retries, so a single bad response affects all attempts. -**→ F-030: No output validation on SquidRouter swap; retries amplify losses from malicious routes.** - -**Check 11 — Post-swap routing covers all cases:** ⚠️ PARTIAL. `subsidize-post-swap-handler.ts` lines 128-148: -- **BUY + assethub + USDC** → `pendulumToAssethubXcm` ✅ -- **BUY + assethub + non-USDC** → `pendulumToHydrationXcm` ✅ -- **BUY + non-assethub** → `pendulumToMoonbeamXcm` ✅ -- **SELL + BRL** → `pendulumToMoonbeamXcm` ✅ -- **SELL + non-BRL** → `spacewalkRedeem` ✅ - -The routing looks comprehensive for current flows. However, there is no explicit handling for `SELL + USD` (Alfredpay offramp) — this flow goes through `finalSettlementSubsidy` from `fund-ephemeral-handler.ts` and never reaches `subsidize-post-swap-handler.ts`. If a new offramp flow is added that uses post-swap subsidization with a non-BRL, non-Stellar output, it would default to `spacewalkRedeem` which may not be correct. **→ F-031: No `default` case with error for unrecognized routing combinations — silent misrouting possible for future flows.** - -**Check 12 — Funding account balance checked before subsidization:** 🔴 FAIL. -- `subsidize-pre-swap-handler.ts`: No check of funding account balance before calling `api.tx.tokens.transfer()`.

The spec described it slightly differently ("falls below"), but the actual implementation is "BRLA overfull AND USDC.axl underfull" which is correct for a BRLA→axlUSDC rebalancing direction. - ---- - -#### Checklist Item 6: Rebalancer private keys distinct from API service keys - -**`[PASS]`** - -In `config.ts` lines 6-8, the rebalancer uses: -- `PENDULUM_ACCOUNT_SECRET` (mnemonic → sr25519 keypair via Keyring) -- `MOONBEAM_ACCOUNT_SECRET` (mnemonic → EVM account via `mnemonicToAccount`) -- `POLYGON_ACCOUNT_SECRET` (mnemonic → EVM account via `mnemonicToAccount`) - -In `apps/api/src/constants/constants.ts`, the API uses: -- `PENDULUM_FUNDING_SEED` -- `MOONBEAM_EXECUTOR_PRIVATE_KEY` -- `FUNDING_SECRET` (Stellar) - -Different env var names. Key isolation depends on operators actually using distinct keys in production deployment. Cannot verify from code that the same mnemonic/key is not reused — this is an operational verification. The architecture correctly expects separation. - ---- - -#### Checklist Item 7: Step idempotency — safe re-execution after crash - -**`[PARTIAL — F-033]`** - -The orchestrator in `index.ts` uses `currentOrder <= N` checks to determine which steps to execute on resume. If the process crashes mid-step, it resumes from the last saved phase. Analysis of each step: - -| Step | Idempotent? | Details | -|---|---|---| -| 1. Check balance | ✅ Yes | Read-only — no state mutation | -| 2. Swap USDC→BRLA | ❌ **No** | Submits a swap extrinsic. If crash occurs after swap submits but before `saveState`, the swap is re-executed on resume, causing **double swap** | -| 3. Send BRLA→Moonbeam | ❌ **No** | Submits XCM transfer. Same crash window as step 2 — **double XCM** | -| 4. Poll balance | ✅ Yes | Read-only polling | -| 5. Swap BRLA→USDC | ❌ **No** | Creates a swap ticket on BRLA API. If crash after ticket creation but before `saveState`, a **duplicate ticket** is created on resume | -| 6. SquidRouter transfer | ❌ **No** | Sends approve + swap transactions on Polygon. If crash after swap tx but before `saveState`, funds are already on Moonbeam but state says to redo | -| 7. Trigger XCM | ❌ **No** | Calls `executeXCM` on receiver contract. If crash after execution but before `saveState`, **double XCM** from Moonbeam to Pendulum | -| 8. Wait for arrival | ✅ Yes | Read-only polling | - -Steps 2, 3, 5, 6, and 7 have a crash window between step execution and `saveState()` where re-execution causes double-spend. There are no transaction hash guards, nonce guards, or balance pre-checks to detect that a step already executed. - -**New finding: F-033** — See FINDINGS.md. - ---- - -#### Checklist Item 8: BRLA→USDC swap validates received amount - -**`[PARTIAL]`** +**Spec:** `02-signing-keys/server-side-signing.md` -In `steps.ts` lines 281-320: The `swapBrlaToUsdcOnBrlaApiService` function creates a quote, creates a ticket, polls for ticket status to become `PAID`, then reads the paid ticket's `quote.outputAmount`. It then calls `waitForUSDCOnPolygon` to confirm the USDC actually arrived on-chain. So it does verify the USDC arrives — but it does not compare the arrived amount to the quoted amount. The function trusts the BRLA API's reported `paidAmount` and then polls for exactly that amount on-chain. If the BRLA API reported a manipulated (lower) amount, the function would proceed with less USDC than expected. +#### 1. `[PARTIAL]` `FUNDING_SECRET` purpose separation +Also aliased as `SEP10_MASTER_SECRET` — same key for funding and Stellar web authentication. → [F-022](FINDINGS.md) ---- +#### 2. `[PASS]` `PENDULUM_FUNDING_SEED` used only for funding ephemerals +Used in `subsidize.controller.ts` and `pendulum.service.ts` for funding/subsidization only.

One-shot process — concurrency depends on deployment. -In `express.ts` lines 26-38: CORS is configured with a static array of origins. No wildcard `*`, no `origin: true`, no callback that echoes back the request origin. The `credentials: true` option is set, which requires a specific origin (not `*`). The implementation is correct — explicit origin whitelist. +#### 2. `[PARTIAL]` `brlaBusinessAccountAddress` hardcoded default +Configurable via env var, but falls back to hardcoded address. Not in `.env.example`. -The CORS config also explicitly lists `allowedHeaders: ["Content-Type", "Authorization"]`. The `X-API-Key` header used by `apiKeyAuth.ts` is NOT in the allowed headers list. This means browsers making CORS requests with `X-API-Key` would have the header stripped. However, since `X-API-Key` is used for server-to-server SDK calls (not browser-to-API), this is likely intentional. +#### 3. `[PASS]` 5% slippage tolerance +Hardcoded `0.95` multiplier. Reasonable for default small amounts ($1 USD). ---- +#### 4. `[PASS]` Gas 5x multiplier +Aggressive but ensures inclusion on Polygon. Gas is typically cheap. -#### Checklist Item 5: Rate limit bypass via `X-Forwarded-For` +#### 5. `[PASS]` Coverage ratio threshold +`1 + 0.25` threshold. Configurable via env var.

Actual isolation is operational. -In `express.ts` line 43: `app.set("trust proxy", Number(rateLimitNumberOfProxies))`. Default is `1` proxy. `express-rate-limit` uses `req.ip` which respects `trust proxy`. Setting `trust proxy` to a specific number (not `true`) prevents arbitrary `X-Forwarded-For` spoofing — only the Nth-from-last IP in the chain is trusted. This is correct for typical single-proxy (load balancer) deployments. +#### 7. `[PARTIAL]` Step idempotency +Steps 2, 3, 5, 6, 7 have crash windows between execution and `saveState()` causing double-spend on re-execution.

Other errors use `err.message` — which could potentially contain database error messages. -- `notFound` (line 72-77): Returns static "Not found" message. - -The `errors` array comes from `express-validation` which contains field names from the request (user-facing), not database internals. However, for non-validation errors, `err.message` is passed directly. If a Sequelize error message propagates (e.g., "column X does not exist"), it would be exposed. This is a theoretical risk — Sequelize errors typically hit the generic error converter. +### 07b — Secret Management ---- +**Spec:** `07-operations/secret-management.md` -#### Checklist Item 9: `errors` array contains only user-facing messages +#### 1. `[PASS]` No secrets manager — plain env vars +Confirmed limitation.

Sends the **full Nabla swap output**. | +| `amountForPayout` (balance check) | `quote.metadata.nablaSwapEvm.outputAmountDecimal` | Sanity check that Avenia received the full deposit before initiating PIX. | +| `amountForQuote` (Avenia PIX payout) | `quote.outputAmount.round(2,0)` | The **net BRL the user receives via PIX**. Equals deposit minus Avenia anchor fee. | + +The invariant `transferAmount ≥ payoutAmount` must hold (transfer covers payout + anchor fee). If Nabla underdelivers, the balance-poll timeout fails the phase before any PIX is attempted. ## Security Invariants -1. **BRLA API credentials MUST be stored as environment variables** — API key, secret, and any session tokens must come from env vars, never hardcoded. -2. **PIX amounts MUST match the quoted BRL amount** — The amount in the BRLA payout request must be derived from the ramp's stored quote, accounting for BRLA's anchor fee. -3. **User tax ID (CPF) MUST be validated** — CPF format validation before sending to BRLA. Malformed CPFs should be rejected at ramp registration, not at payout time. -4. **BRLA subaccount creation MUST be idempotent** — If a subaccount already exists for a tax ID, the system should not create a duplicate. -5. **BRLA anchor fee MUST be pre-accounted in the quoted amount** — The user's quoted BRL output has already deducted BRLA's fee. The payout amount sent to BRLA must be the gross amount (before BRLA's fee), so the user receives the net quoted amount. -6. **PIX payment confirmation MUST be verified before advancing** — On-ramp: The system must confirm that BRLA received the PIX payment before minting. Off-ramp: The system must confirm the payout was triggered successfully. -7. **BRLA API responses MUST be validated** — Status codes, transaction IDs, and amount confirmations must be checked. Unexpected responses should not advance the phase. -8. **BRLA interactions MUST be retryable** — Transient BRLA API failures should throw `RecoverablePhaseError`, allowing the phase processor to retry. +1. **Avenia API credentials MUST be stored as environment variables** — API key, secret, and any session tokens come from env vars, never hardcoded. +2. **PIX payout amount MUST equal `quote.outputAmount`** — `createPayOutQuote.outputAmount` is derived from the immutable stored quote; the user receives exactly the quoted net BRL (after Avenia anchor fee). +3. **The on-chain BRLA transfer amount MUST equal `quote.metadata.nablaSwapEvm.outputAmountRaw`** — This guarantees the full Nabla output reaches Avenia; Avenia keeps the anchor fee and pays the user the net amount. +4. **`brlaPayoutOnBase` MUST NOT initiate the PIX payout until the Avenia balance reflects the deposit** — The balance poll prevents calling `createPixOutputTicket` against funds that have not yet been credited. +5. **User tax ID (CPF) MUST be validated** — CPF format validation at ramp registration, not at payout time. +6. **Avenia subaccount creation MUST be idempotent** — If a subaccount already exists for a tax ID, the system must not create a duplicate. +7. **PIX payment confirmation MUST be verified before advancing on-ramp** — `brlaOnrampMint` polls the Base ephemeral balance; advancement only on confirmed BRLA arrival. +8. **Avenia API responses MUST be validated** — Status codes, ticket IDs, and amount confirmations must be checked. `AveniaTicketStatus.FAILED` must throw an unrecoverable error; any other unexpected value must not advance the phase. +9. **Avenia interactions MUST be retryable** — Transient Avenia API failures throw `RecoverablePhaseError`; the phase processor retries. +10. **Recovery on resumed `brlaPayoutOnBase` MUST detect existing tickets** — If `payOutTicketId` is already in state, the handler skips re-issuing the PIX ticket and only polls status (prevents double-payout). +11. **Recovery on resumed on-chain transfer MUST detect existing tx hashes** — If `brlaPayoutTxHash` is in state, the handler waits for that receipt rather than re-broadcasting (prevents double on-chain BRLA transfer). +12. **PIX deposit details (QR code) MUST be generated server-side** — Returned via API response only after presigned transactions are validated, never client-modifiable. ## Threat Vectors & Mitigations | Threat | Attack Scenario | Mitigation | |---|---|---| -| **PIX payment spoofing (on-ramp)** | Attacker claims PIX payment was made without actually paying | System relies on BRLA's payment confirmation, not user's claim; wait for BRLA to confirm receipt | -| **Tax ID fraud** | Attacker uses someone else's CPF to create a subaccount and receive off-ramp payouts | Tax ID validation is BRLA's responsibility at KYC level; Vortex should pass through validated data only | -| **Double payout (off-ramp)** | Bug causes `triggerOfframp` to be called twice for the same ramp | Phase processor's locking + phase history prevents double execution; BRLA should also have idempotency on their side | -| **BRLA API compromise** | Attacker intercepts or manipulates BRLA API calls | HTTPS enforcement; validate response amounts; monitor for discrepancies | -| **Amount manipulation between quote and payout** | Attacker modifies the payout amount between quote creation and execution | Payout amount derived from immutable quote stored in DB; not recalculated at execution time | -| **BRLA service outage** | BRLA API is unreachable during an active ramp | `RecoverablePhaseError` with retry; ramp waits in current phase until BRLA recovers | -| **Subaccount leak** | BRLA subaccount details (balances, transaction history) exposed via API | Minimize data stored about BRLA subaccounts; only store what's needed for ramp operation | +| **PIX payment spoofing (on-ramp)** | Attacker claims PIX payment was made without actually paying | System polls Base RPC for actual BRLA arrival; never trusts user claim. | +| **Tax ID fraud** | Attacker uses someone else's CPF to receive off-ramp payouts | Tax ID validation is Avenia's responsibility at KYC level; Vortex passes through validated data only. | +| **Double payout (off-ramp)** | Bug causes `createPixOutputTicket` to be called twice for the same ramp | (a) Phase processor's per-ramp lock prevents concurrent execution; (b) `payOutTicketId` recovery branch skips re-issue; (c) `brlaPayoutTxHash` recovery branch skips re-broadcast. | +| **Double on-chain transfer** | Crash between sending the BRLA transfer and storing the hash | Handler stores `brlaPayoutTxHash` only after the receipt. On retry, if no hash is stored, the same presigned tx is re-broadcast — EVM nonce uniqueness prevents double-spend. | +| **Avenia API compromise** | Attacker intercepts or manipulates Avenia API calls | HTTPS enforced; balance verified on-chain against deposit; PIX amount derived from immutable quote. | +| **Amount manipulation between quote and payout** | Attacker modifies the payout amount between quote and execution | `quote.outputAmount` read from DB at execution time; quote is immutable post-creation. | +| **Avenia service outage** | Avenia API is unreachable mid-ramp | `RecoverablePhaseError` → phase processor retries; off-ramp fails to payout but BRLA is held on the Avenia subaccount, not lost. | +| **Subaccount data leak** | Avenia subaccount details exposed via API | Only `subAccountId`, EVM wallet address, and balances are stored locally; no PII beyond CPF (which is itself a regulatory requirement). | +| **Underdelivery from Nabla** | Nabla swap returns less BRLA than quoted, balance poll times out, ramp stuck | Balance-poll timeout (5min) fails the phase as recoverable; `subsidizePostSwapEvm` is supposed to top up shortfalls — but see `fund-routing.md` for the missing EVM USD cap. | ## Audit Checklist -- [x] BRLA API credentials loaded from environment variables (not hardcoded). **PASS** — verified: credentials loaded from env vars. -- [x] `brlaOnrampMint` handler verifies BRLA payment confirmation before minting/teleporting tokens. **PASS** — handler polls BRLA API for payment status before proceeding. -- [x] `brlaPayoutOnMoonbeam` handler passes the correct gross amount (accounting for BRLA's fee deduction). **PASS** — amount derived from ramp state quote values. -- [x] User CPF/tax ID is validated for format before being sent to BRLA. **PASS** — CPF validation present in registration flow. -- [x] BRLA subaccount creation is idempotent — no duplicate subaccounts for the same tax ID. **PASS** — checks existing subaccount before creating. -- [PARTIAL] BRLA API responses are validated (status code, amount confirmation, transaction ID). **PARTIAL** — shared package (`@packages/shared`) used for BRLA client;

Optional `backupSquidRouterApprove` / `backupSquidRouterSwap` on the destination chain if the bridged token (axlUSDC / USDC) needs further conversion to the user's requested output token. **F-054 carried over: these `backup*` presigned txs have no registered phase handler.** +6. `destinationTransfer` to the user. + +### Off-ramp flow (user EVM source → Base USDC) + +1.

Gas paid by `MOONBEAM_EXECUTOR_PRIVATE_KEY`. + - **No-permit fallback** (commit `b45768be3`, `isNoPermitFallback=true`): user's own wallet broadcasts `squidRouterNoPermitApprove` + `squidRouterNoPermitSwap` (or `squidRouterNoPermitTransferHash` for direct-transfer subcase). Frontend reports the resulting tx hashes back via `UpdateRampRequest.additionalData`. Backend awaits receipts via `waitForUserHash`. **No presigned-tx validation runs for these phases** — they are user-submitted (see `transaction-validation.md`). + - **Direct transfer** (`isDirectTransfer=true`): same-chain same-token, user wallet submits a direct ERC-20 transfer to the Base ephemeral. +2. `squidRouterPay`: monitors Axelar GMP for arrival on Base. +3.

Tokens are pulled from user's wallet, approved, and routed in one atomic on-chain transaction +When the BRL on-ramp's destination is **Base + USDC**, the Nabla swap output is already the requested output token. The route builder in `avenia-to-evm-base.ts:100` skips the `squidRouterApprove`/`squidRouterSwap`/`backup*` presigned transactions entirely and emits only a `destinationTransfer`. The quote engine `BaseSquidRouterEngine` (`squidrouter/index.ts`) emits 1:1 passthrough bridge meta with `networkFeeUSD = "0"` so downstream stages (discount, finalize) work without fetching a Squid route (which would fail with "same token same chain"). Discount engine (`onramp.ts`) and fee engine (`onramp-brl-to-evm.ts`) likewise short-circuit to a 1:1 rate / zero network fee in this case. -**Special case:** Alfredpay on-ramp to USDC on Polygon skips SquidRouter entirely (handled by direct mint on Polygon → `destinationTransfer`). +**No security checks are bypassed by this path** — destination address validation runs in the quote `validate` step regardless; the only thing skipped is the Squid HTTP call. ## Security Invariants -1. **Approve transaction MUST be confirmed before swap execution** — The handler waits for approve receipt before sending the swap. Hash is persisted to state immediately for crash recovery. -2. **Bridge status uses dual-check (Squid + Axelar fallback)** — If SquidRouter status API fails, the handler falls back to `getStatusAxelarScan()` directly. Both must fail before the phase errors. -3. **Balance check and bridge check run as `Promise.any` race** — Either the balance arriving or the bridge reporting success is sufficient. Both must fail (via `AggregateError`) to error the phase. -4. **Axelar gas funding MUST use `addNativeGas` on the correct chain** — Moonbeam for BRL flows, Polygon for EUR/USD flows. The funding amount is computed from Axelar's fee response. -5. **Gas subsidy cap: `MAX_FINAL_SETTLEMENT_SUBSIDY_USD` MUST be enforced** — In `final-settlement-subsidy.ts`, the swap amount for subsidization is checked against a USD cap to prevent excessive spending. -6. **Permit execution MUST verify both permit and payload signatures** — `squidRouterPermitExecute` extracts v/r/s from both `permitTypedData` and `payloadTypedData`. Both must be valid `SignedTypedData` objects. -7. **`MOONBEAM_EXECUTOR_PRIVATE_KEY` is the relayer caller** — This key pays gas for `TokenRelayer.execute()`. It MUST NOT hold user funds. -8. **Transaction hashes MUST be persisted to state before waiting** — `squidRouterApproveHash`, `squidRouterSwapHash`, `squidRouterPayTxHash`, `squidRouterPermitExecutionHash` enable crash recovery. -9. **Nonce mismatch is warned but not blocked** — The handler logs a warning if the account nonce differs from the transaction nonce. This is a design choice — a stale nonce may self-resolve on retry. +1. **Approve transaction MUST be confirmed before swap execution** — Approve hash persisted to state immediately for crash recovery. +2. **Bridge status uses dual-check (Squid + Axelar fallback)** — If Squid status API fails, falls back to `getStatusAxelarScan()`. Both must fail before phase errors. +3. **Balance check and bridge check MUST race via `Promise.any`** — Either balance arriving or bridge reporting success is sufficient; both must fail (`AggregateError`) to error. +4. **Arrival check MUST have a finite timeout** — `EVM_BALANCE_CHECK_TIMEOUT_MS` (15 minutes) bounds how long a phase waits before erroring. **(Commit `f7905dc40` ensures `waitUntilTrue` enforces a timeout.)** +5. **Squid API rate-limit responses MUST be retried with backoff** — 429 responses are retried with exponential backoff before failing the phase (commit `ff0b82feb`). Other errors propagate directly. +6. **Axelar gas funding MUST use `addNativeGas` on the correct chain** — The funding source/chain is selected based on the route, not from request input. +7. **Permit execution MUST verify both permit and payload signatures** — `squidRouterPermitExecute` extracts v/r/s from both `permitTypedData` and `payloadTypedData`; both must be valid `SignedTypedData`. +8. **`MOONBEAM_EXECUTOR_PRIVATE_KEY` is the relayer caller** — Funds gas only; MUST NOT hold user funds. +9. **No-permit fallback MUST verify on-chain receipt for every reported user hash** — `waitForUserHash` calls `waitForTransactionReceipt`; non-success status throws `RecoverablePhaseError`. The user-reported hash itself is trusted (no signature verification — the receipt confirms it succeeded, which is sufficient because the user controls the source funds either way). +10. **No-permit fallback MUST NOT advance to `fundEphemeral` until BOTH approve and swap (or the direct transfer) have confirmed** — Sequential `waitForUserHash` calls in `executeNoPermitFallback` enforce this. +11. **Transaction hashes MUST be persisted to state before waiting** — `squidRouterApproveHash`, `squidRouterSwapHash`, `squidRouterPayTxHash`, `squidRouterPermitExecutionHash`, `squidRouterNoPermitApproveHash`, `squidRouterNoPermitSwapHash`, `squidRouterNoPermitTransferHash` all enable crash recovery. +12. **Skip-Squid path MUST NOT lose destination validation** — Quote engine `validate()` runs regardless of `skipRouteCalculation`; `destinationTransfer` is the only on-chain step that fires. ## Threat Vectors & Mitigations | Threat | Mitigation | |---|---| -| **Bridge funds stuck in transit** — Axelar GMP message fails or stalls mid-bridge | Dual monitoring (Squid API + Axelar scan). 15-minute balance check timeout. Phase retries on failure. Gas is proactively funded via `addNativeGas`. | -| **Gas overpayment to Axelar** — Incorrect gas fee calculation drains the executor wallet | `calculateGasFeeInUnits()` uses Axelar's reported base fee + estimated gas × source gas price × multiplier. Result is verified non-negative. | -| **Double-spend of approve/swap** — Crash between approve and swap causes re-execution | Approve hash is persisted immediately. On re-entry, handler checks if approve hash exists and skips to swap. | -| **Permit replay** — TokenRelayer permit+payload signatures replayed | Each permit has a nonce and deadline. The TokenRelayer contract validates these. Replay with the same nonce reverts on-chain. | -| **Executor key compromise** — Attacker gains `MOONBEAM_EXECUTOR_PRIVATE_KEY` | Attacker can call `execute()` with their own signatures but cannot steal user funds already in the relayer flow. The key funds gas only. Blast radius: gas balance drain. | -| **Squid Router API manipulation** — Fake status "success" returned before actual settlement | Balance check runs in parallel. Even if Squid reports success prematurely, the phase also verifies that tokens actually arrived (for EVM destinations). | -| **Transaction not found during confirmation** — Network propagation delay | Exponential backoff retry (5s → 10s → 20s → 30s cap), up to 4 attempts for `waitForTransactionConfirmation`. | +| **Bridge funds stuck in transit** | Dual monitoring (Squid + Axelar scan). 15-minute arrival timeout (commit `f7905dc40`). Phase retries on failure. Gas proactively funded via `addNativeGas`. | +| **Gas overpayment to Axelar** | `calculateGasFeeInUnits()` uses Axelar's reported base fee + estimated gas × source gas price × multiplier. Result verified non-negative. | +| **Double-spend of approve/swap** | Approve hash persisted immediately; on re-entry handler skips to swap if hash exists. EVM nonce prevents on-chain double-spend in any case. | +| **Permit replay** | Each permit has a nonce + deadline; TokenRelayer validates on-chain. | +| **Executor key compromise** | Attacker can call `execute()` with their own signatures but cannot steal in-flight user funds — the key only pays gas. Blast radius: gas balance drain. | +| **Squid Router API manipulation (fake "success")** | Balance check runs in parallel; even if Squid reports premature success, tokens must actually arrive. | +| **Squid rate limit (429)** | Exponential backoff retry (commit `ff0b82feb`); other errors fail fast. | +| **Transaction not found during confirmation** | Exponential backoff retry (5s → 10s → 20s → 30s cap), up to 4 attempts. | +| **No-permit fallback hash spoofing** | User reports tx hash → backend calls `waitForTransactionReceipt(hash)`. Hash is verified against actual chain state, not trusted blindly. The worst the user can do is report a hash that doesn't exist (handler errors recoverably) or a hash for a different transaction (receipt's `to`/`value` are not currently re-checked — see open question below). | +| **No-permit allowance window attack** | The `squidRouterNoPermitApprove` grants Squid an allowance from the user's wallet; if the swap hash never confirms, the allowance lingers. The user wallet, not Vortex, retains the risk. UX should remind the user to revoke unused allowances; backend cannot revoke on the user's behalf. | +| **Skip-Squid trivial-case manipulation** | The skip path triggers only when destination is Base+USDC, validated server-side by the quote engine before any presigned tx is generated. Attacker cannot force the skip path on non-Base/non-USDC routes. | -**⚠️ FINDING:** In `squid-router-phase-handler.ts` line 147, `getPublicClient()` defaults to Moonbeam if `inputCurrency` doesn't match any known case and logs "This is a bug."

They warrant follow-up. + +### F-NEW-08 — Skip-Squid path: validation parity with full path (LOW, investigate) + +The skip-Squid trivial path (Base+USDC destination) emits only a `destinationTransfer` presigned tx. The destination address validation that normally runs during quote `validate()` is shared between paths, so no checks are bypassed in principle — but a code-side audit comparing the two paths phase-by-phase would be reassuring. + +### F-NEW-09 — `payOutTicketId` recovery branch and `brlaPayoutTxHash` recovery branch interaction (LOW, edge case) + +`brla-payout-base-handler.ts` has two independent recovery branches (existing ticket ID, existing tx hash). If a ramp recovers with both fields set, the handler short-circuits to `checkTicketStatusPaid` before re-broadcasting the on-chain tx. Confirm: is it possible to reach a state where the on-chain tx never confirmed but a ticket exists? If yes, polling-only recovery would miss the on-chain failure. + +### F-NEW-10 — Avenia anchor-fee assumption in three-amount model (MEDIUM, monitoring) + +The off-ramp three-amount model assumes `transferAmount ≥ payoutAmount` (i.e., Avenia anchor fee ≥ 0). If Avenia ever introduces a credit or promotional rate that violates this, `quote.outputAmount` could exceed the deposited BRLA.

Update all callers in `subsidize-*-evm-handler.ts`, `final-settlement-subsidy.ts`, `avenia-to-evm-base.ts`, and any Squid handler that funds gas.

Dead `evm-to-brl.ts` route deleted. | +| 3 | **F-NEW-06b** (MEDIUM) — Surface or fail-fast on partner `payout_address_evm` NULL (silent markup loss). | RESOLVED — quote-time rejection (`APIError 400`) when partner has markup AND `payout_address_evm` NULL on EVM-payout routes; runtime WARN if it slips through. | +| 4 | **F-NEW-04** (MEDIUM) — Harden no-permit fallback receipt validation. | RESOLVED — `waitForUserHash` now verifies receipt `to` and tx `input` against the presigned `EvmTransactionData`. | +| 5 | **F-NEW-11** (MEDIUM) — Re-evaluate F-029 severity with Base in scope. | RESOLVED — `fund-routing.md` and `secret-management.md` updated to reflect Base blast radius (BRLA payouts, EVM fee distribution, ephemeral subsidization across all EVM chains). | +| 6 | **F-NEW-06a** (LOW) — Add `DEFAULT_VORTEX_EVM_PAYOUT_ADDRESS` env-var fallback. | RESOLVED — `config.defaults.vortexEvmPayoutAddress` falls back when `vortexPartner.payoutAddressEvm` is NULL. | +| 7 | **F-NEW-07** (LOW, mostly hygiene) — Rename `MOONBEAM_FUNDING_PRIVATE_KEY` → `EVM_FUNDING_PRIVATE_KEY` with proper getter abstraction. | RESOLVED — new `EVM_FUNDING_PRIVATE_KEY` env (back-compat fallback to `MOONBEAM_EXECUTOR_PRIVATE_KEY`); all 13 call sites migrated to `getEvmFundingAccount(network)` helper at `apps/api/src/api/services/phases/evm-funding.ts`. | +| 8 | **F-NEW-03** (LOW) — Tighten `backupApprove` allowance from `maxUint256` to a calculated bound. | RESOLVED — `avenia-to-evm-base.ts` `backupApprove` now uses `inputAmountRawFinalBridge × 1.05`. | +| 9 | **F-NEW-08** — Investigate skip-Squid passthrough divergence. | NO BUG — same-chain same-token passthrough has no Squid fee; `networkFeeUSD="0"` and 1:1 rate are correct. | +| 10 | **F-NEW-09** — Investigate BRLA payout recovery branches. | NO BUG — once `payOutTicketId` exists, BRLA acknowledged the EVM payout; on-chain receipt is no longer authoritative. | +| 11 | **F-NEW-10** — Avenia anchor-fee assumption in three-amount model. | RESOLVED — `evm-to-brl-base.ts` asserts `brlaTransferAmountRaw ≥ quote.outputAmount * 10^brlaDecimals`. | +| 12 | **F-NEW-05** — Defer until custody solution is designed (per team decision). | DEFERRED — accepted risk; no EVM cleanup transactions implemented. | From 859174c13a41b397c61620d158d18e6b05005602 Mon Sep 17 00:00:00 2001 From: Marcel Ebert Date: Mon, 11 May 2026 13:36:24 +0200 Subject: [PATCH 32/90] WIP --- .../handlers/destination-transfer-handler.ts | 4 +- .../squidrouter-permit-execution-handler.ts | 23 +++ .../offramp/routes/evm-to-brl-base.ts | 1 - .../transactions/offramp/routes/evm-to-brl.ts | 149 ------------------ docs/security-spec/SPEC-DELTA-2026-05.md | 2 +- 5 files changed, 26 insertions(+), 153 deletions(-) delete mode 100644 apps/api/src/api/services/transactions/offramp/routes/evm-to-brl.ts diff --git a/apps/api/src/api/services/phases/handlers/destination-transfer-handler.ts b/apps/api/src/api/services/phases/handlers/destination-transfer-handler.ts index ca6f58f1e..fc639b609 100644 --- a/apps/api/src/api/services/phases/handlers/destination-transfer-handler.ts +++ b/apps/api/src/api/services/phases/handlers/destination-transfer-handler.ts @@ -29,7 +29,7 @@ function validateDestinationTransferRecipient(rawTx: `0x${string}`, expectedDest if (isNativeTransfer) { if (decoded.to.toLowerCase() !== expectedDestination.toLowerCase()) { throw new Error( - `DestinationTransferHandler: Native transfer recipient mismatch. ` + + "DestinationTransferHandler: Native transfer recipient mismatch.

Rotate the Supabase project's `service_role` JWT secret in the Supabase dashboard. This invalidates the leaked token immediately. +2. Audit Supabase access logs for unauthorized usage of the leaked token between commit `0e2074e85` (2026-03-23) and rotation time. +3. Refactor the trigger to read the JWT from a runtime source instead of inlining it. Recommended approaches: + - Use Supabase **Vault** (`vault.decrypted_secrets`) and reference the secret by name inside the trigger body. + - Or move the Slack notification out of the database trigger and into application code where the secret comes from `process.env`. +4.

The repository has been public on GitHub since at least 2024-05. +2. GitHub caches forks, pull requests, and unreachable commits indefinitely. Force-pushing a rewritten history does not delete those caches. +3. Any third party may have already cloned, mirrored, or scraped the repository. +4. The leaked Supabase JWT and Stellar secret must be rotated regardless of whether history is rewritten. + +**Recommended approach: rotate, do not rewrite.** + +1. Treat all already-leaked secrets as compromised forever. Rotate. +2. Patch the working tree so future commits are clean. +3. Add CI-level secret scanning (e.g., `gitleaks`, `trufflehog`, GitHub's native push protection) to catch the next leak before it reaches `origin`. +4. Optionally delete obsolete branches (`offramp-prototype`, `main-backup-pre-widget`, completed feature branches) to reduce the public surface, but understand that anything cached by GitHub or third parties remains accessible. + +If, after rotation, leadership still requires a history rewrite for compliance or appearance reasons: + +1. Coordinate with every active developer (force-push will require everyone to re-clone). +2. Use `git filter-repo --invert-paths --path signer-service-rust/.env --path signer-service/.env --path 'api/src/api/services/phases/lastRampState*.json' --path 'signer-service/src/api/services/phases/failedRampStateRecovery.json'`. +3. For the Supabase migration, use `git filter-repo --replace-text` to substitute the JWT with a placeholder, preserving the rest of the file. +4. Force-push to all branches on `origin`. +5. Open a GitHub support ticket to purge cached PRs and unreachable commits. + +This is significant operational disruption with marginal security benefit.

The PolygonPostProcessHandler runs against them and sweeps any user-approved residual via `transferFrom`. F-046 is therefore resolved by the worker change. | | **Premature Moonbeam cleanup** | Cleanup runs before the 3-hour SquidRouter refund window expires. Refunded tokens land on an already-swept ephemeral account. | MoonbeamPostProcessHandler enforces `MOONBEAM_CLEANUP_DELAY_MS` (3 hours). Verify this delay is checked before every Moonbeam cleanup, not just on first attempt. | | **Ephemeral key loss** | Client generates the ephemeral keypair, but if the client disconnects or loses the key before cleanup, the server needs cosigner authority to sweep. If cosigner was never set (see F-040), cleanup is impossible. | Ensure SetOptions/multisig setup is validated at registration time. Server cosigner must be confirmed before the ramp starts. | | **Cleanup worker saturation** | A burst of completed ramps overwhelms the worker (only 5 per cycle).

The following describes the intended fee structure after the ongoing refactoring is complete: - -1. **Calculation Point:** All fees are calculated and factored in during the **quote generation phase** (`api/src/api/services/ramp/quote.service.ts`). The final output amount shown to the user in the quote reflects the total fee impact. -2. **Fee Source:** Fee parameters and logic are sourced entirely from the **database**, specifically the `FeeConfiguration` and `Partner` tables. Token configuration files in the `shared` module will no longer be used for fee definitions. -3. **Fee Components:** The total fee is composed of several parts, calculated initially in USD: - * **`network` Fee:** Aims to cover the estimated on-chain transaction costs (e.g., gas, XCM, Stellar fees) required for the entire ramp process. The exact calculation logic is determined within `calculateGrossOutputAndNetworkFee`. - * **`vortex` Fee:** The platform fee, defined by the `vortex_foundation` record in the `Partner` table (can be absolute or relative). - * **`anchor` Fee:** The fee charged by the specific fiat anchor service involved (e.g., BRLA, Stellar EURC anchor). This is sourced from the `FeeConfiguration` table based on `feeType: 'anchor_base'` and an identifier matching the anchor (e.g., `moonbeam_brla`). Can be absolute, relative, or a combination. - * **`partnerMarkup` Fee:** An optional additional fee applied by an external partner integrating with the ramp service, defined in their specific `Partner` table record (can be absolute or relative). -4. **Application Logic & Charging:** - * The individual fee components (`network`, `vortex`, `anchor`, `partnerMarkup`) are calculated during the quote phase. - * The **`anchor` fee** is charged by the respective anchor service (BRLA or Stellar) in the native fiat currency (e.g., BRL, EURC) during the phase where interaction with the anchor occurs. The system must account for this deduction when initiating transfers to/from the anchor. - * On-Ramp BRL: Charged by BRLA during `brlaOnrampMint`. - * Off-Ramp BRL: Charged by BRLA during `brlaPayoutOnMoonbeam`. - * Off-Ramp Stellar (EURC, ARS, etc.): Charged by the Stellar anchor during `stellarPayment`. - * The **`vortex`**, **`network`**, and **`partnerMarkup` fees** are handled separately. They are effectively set aside from the main flow and distributed to their respective destination accounts during a dedicated `distributeFees` phase. - * On-Ramp: `distributeFees` occurs *after* the swap but *before* post-swap subsidization. - * Off-Ramp: `distributeFees` occurs *before* the pre-swap subsidization. - * The **final net amount** delivered to the user (crypto for on-ramp, fiat for off-ramp) is the `grossOutputAmount` (post-swap amount) minus the total impact of all fee components. -5. **Fee Display:** The fee breakdown (`FeeStructure`) shown to the user in the quote response is presented in the relevant **fiat currency** for the transaction (e.g., BRL, EUR, ARS), converted from the initial USD calculations. - -## Ramp Journeys - -The ramp process is managed by a state machine, transitioning through various phases handled by dedicated services. - -**Common Initial Steps:** - -1. **Quote Request:** User requests a quote (`quote.service.ts`). Fees are calculated and applied as described above. -2. **Register Ramp:** User accepts the quote. The system validates the quote, prepares necessary unsigned transactions based on the fee-adjusted amounts, and creates a `RampState` record (`ramp.service.ts`). The initial phase is set to `initial`. -3. **Start Ramp:** User signs transactions client-side and submits them. The system validates signatures, updates the `RampState`, and triggers the `phaseProcessor` (`ramp.service.ts`). -4. **Phase: `initial` (`initial-phase-handler.ts`):** Checks for signed transactions (off-ramp).

The top-up — a **subsidy** — is paid from a platform-funded account during a subsidy phase later in the ramp. The discount stage does not move funds; it only computes how much subsidy a given quote needs. + +For each quote, the discount engine: + +1. Resolves an `ActivePartner` row (the request's `partnerId`, or the system default `vortex`). +2. Reads two partner-scoped parameters: + - `targetDiscount` — the discount to advertise. A positive `targetDiscount` means the user receives **more** than the oracle implies (e.g. `targetDiscount=0.005` means the rate offered is 0.5% better than the oracle rate). + - `maxSubsidy` — a fractional cap on the subsidy as a share of expected output. +3. Reads dynamic state `partnerDiscountState[partner.id]`, which holds a `difference` value that drifts up while no quote is consumed and back down once a quote is consumed, bounded by `[minDynamicDifference, maxDynamicDifference]`. +4. Calculates `expectedOutput = inputAmount × oraclePrice × (1 + targetDiscount + adjustedDifference)`. For offramps the oracle price is inverted first. +5. Calculates `actualOutput` as what the user would receive without subsidy (Nabla output minus post-swap fees on onramp, anchor fee added back on offramp). +6. Calculates `idealSubsidy = max(0, expectedOutput − actualOutput)` and `actualSubsidy = min(idealSubsidy, maxSubsidy × expectedOutput)` (only when `targetDiscount > 0`). +7. Writes a `ctx.subsidy` record consumed by downstream merge-subsidy and finalize stages and ultimately by the subsidy phase handlers. + +The engine is wired by strategy configuration. Of the 10 route strategies in `apps/api/src/api/services/quote/routes/strategies/`, 7 register a discount engine and 3 do **not**: `offramp-evm-to-alfredpay`, `onramp-alfredpay-to-evm`, and `onramp-monerium-to-evm`. On those three routes, no subsidy is computed regardless of partner configuration. + +For onramps to EVM destinations other than AssetHub, the engine also probes Squid Router (`getEvmBridgeQuote`) to convert the oracle-expected amount into the equivalent amount of the *pre-bridge* token (USDC on Base or axlUSDC on Moonbeam) so the subsidy is denominated in the token the ramp actually holds on the source chain. + +## Security Invariants + +1. **Subsidy amount MUST be bounded by `maxSubsidy × expectedOutput`** — when `maxSubsidy > 0`, `calculateSubsidyAmount` clamps the shortfall to `expectedOutput × maxSubsidy`; for higher caps, the full shortfall is paid. The cap MUST always be enforced from the partner row, never from the request. +2. **Discount parameters MUST come from the database**, never from the API request. The engine reads `targetDiscount`, `maxSubsidy`, `minDynamicDifference`, `maxDynamicDifference` from a Sequelize `Partner` row. No request field overrides them. +3. **Dynamic-difference clamping MUST hold both ends.** `getAdjustedDifference` enforces `≤ maxDynamicDifference`; `handleQuoteConsumptionForDiscountState` enforces `≥ minDynamicDifference`. A partner with no caps configured behaves as if both caps were `0` (no dynamic adjustment). +4. **The default partner row (`name = "vortex"`) MUST exist and MUST be `isActive`.** `resolveDiscountPartner` falls back to it when the request supplies no partner or the partner row is inactive. Without an active default, discount computation produces a `null` partner and `targetDiscount=0`, silently disabling subsidies platform-wide. +5. **`targetDiscount` MUST be expressed as a fractional rate (not basis points).** It is added directly to `1` in `calculateExpectedOutput`: `effectivePrice × (1 + targetDiscount + adjustedDifference)`. A value of `0.005` means 0.5%. +6. **Subsidy MUST NOT bypass fee collection.** For onramps, `actualOutput = nablaOutput − (network + vortex + partnerMarkup)`. The subsidy then covers the shortfall against `expectedOutput` *after* those fees, so fees still flow to fee accounts. +7. **For offramps, the anchor fee MUST be added back to `expectedOutput`** before computing the shortfall (`adjustedExpectedOutputDecimal = oracleExpected + anchorFeeInBrl`). Otherwise the user would receive `expectedOutput − anchorFee`, which is short of the advertised rate by the anchor's cut. +8. **Subsidy amounts written to `ctx.subsidy` MUST be deterministic for a given input.** With `targetDiscount=0` the actual subsidy is forced to zero (`actualSubsidyAmountDecimal = Big(0)`), even when `idealSubsidy > 0`. This is the contract the merge-subsidy and subsidy phase handlers rely on. +9. **The dynamic difference MUST NOT be incremented within `discountStateTimeoutMinutes` of the last quote** — `getAdjustedDifference` only adds `deltaD` when `isWithinStateTimeout` is **false**. Otherwise repeated quotes from the same partner would inflate the difference faster than intended. +10. **Squid Router probe failures MUST fall back to a 1:1 assumption, never block the quote.** Both `getSquidRouterUSDCConversionRate` and `getSquidRouterAxlUSDCConversionRate` return `null` on error and the engine proceeds with `adjustedExpectedOutputDecimal = oracleExpectedOutputDecimal`. A network failure on the probe MUST NOT cause the entire quote stage to throw. + +## Threat Vectors & Mitigations + +| Threat | Attack Scenario | Mitigation | +|---|---|---| +| **Subsidy drain via partner row manipulation** | An attacker (or compromised admin endpoint) sets `targetDiscount` or `maxSubsidy` to large values on a partner row, causing the platform to over-subsidize every quote routed through that partner. | Admin endpoints that mutate `Partner` rows MUST be protected by `adminAuth`. Operational monitoring SHOULD alert on `cumulative subsidy per partner per day > threshold`. The `maxSubsidy` field is a hard per-quote ceiling; an organization-level cap is not currently enforced in code. | +| **Quote bursting against dynamic difference** | A client issues many quotes in rapid succession to consume `partnerDiscountState.difference` down to `minDynamicDifference`, then waits for it to drift back up before placing a real ramp at a better rate. | `handleQuoteConsumptionForDiscountState` decreases `difference` by `deltaD` on each *consumed* quote (clamped at `minDynamicDifference`); `getAdjustedDifference` only increases it when `isWithinStateTimeout` is false. Rate limiting at the API layer is the primary defense; the discount state itself only provides eventual mean-reversion. | +| **State loss on process restart re-grants discount** | The `partnerDiscountState` map lives in process memory (`apps/api/src/api/services/quote/engines/discount/helpers.ts:15`). A restart resets every partner's `difference` to `0` and `lastQuoteTimestamp` to `null`, effectively forgiving any in-progress quote consumption. | **Operational risk only — accepted for now.** Until the state is persisted to PostgreSQL, restarts will reset partner positions. Operators MUST treat planned restarts during high-volume periods as a known subsidy leakage vector. | +| **Multi-replica state divergence** | Running the API behind multiple replicas with no sticky routing causes each replica to maintain its own `partnerDiscountState`. The total subsidy paid can exceed the intended cap because each replica enforces its own ceiling independently. | **OPEN (F-DISC-01).** The current deployment topology MUST run a single replica, or the discount state MUST be persisted/centralised (e.g. Redis or a `partner_discount_state` table with row-level locking) before horizontal scaling. | +| **Side-effect on read (cache-poisoning analogue)** | `getAdjustedDifference` mutates `partnerDiscountState` whenever it's called (`partnerDiscountState.set` on lines 106, 111, 120). If a quote pipeline retries the discount stage, the dynamic difference is incremented twice for one logical quote, charging the platform more than intended. | **OPEN (F-DISC-02).** `getAdjustedDifference` MUST be split into a pure reader and an explicit `recordQuoteIssued()` mutator, invoked once per quote at a well-defined point. As long as the discount engine is called exactly once per quote (the current stage pipeline guarantees this), the practical impact is bounded. | +| **Misleading `[CAPPED]` log on zero-discount partners** | `formatPartnerNote` appends `[CAPPED]` whenever `actualSubsidy < idealSubsidy`. When `targetDiscount=0`, line 79 of `offramp.ts` (and 211 of `onramp.ts`) force `actualSubsidy=0`, but `idealSubsidy` can still be positive whenever Nabla undershoots the oracle. Operators reading logs may interpret a flood of `[CAPPED]` notes as `maxSubsidy` exhaustion when the real reason is `targetDiscount=0`. | **OPEN (F-DISC-03).** `formatPartnerNote` SHOULD distinguish "no discount configured" (`targetDiscount=0`) from "discount configured but cap hit" (`targetDiscount>0 && actual Date: Tue, 12 May 2026 10:39:04 +0200 Subject: [PATCH 41/90] Fix BRL on-ramp skipping subsidizePreSwapEvm phase The BRL on-ramp phase chain transitioned fundEphemeral -> nablaApprove directly, leaving subsidizePreSwapEvm unreachable.

The legacy Moonbeam-named env var is only a compatibility fallback and should be phased out operationally so the key's Base/EVM-wide blast radius stays visible. ## Security Invariants 1. **Subsidization MUST only top up to the expected amount, never more** — Both `subsidize-pre-swap-handler.ts` and `subsidize-post-swap-handler.ts` calculate `expectedAmount - currentBalance` and transfer exactly that difference. If the balance already meets or exceeds the expected amount, no transfer occurs. 2. **Expected amounts MUST come from ramp state set at creation time** — The expected input/output amounts are derived from the quote and stored in ramp state. Handlers read these values, not recalculate them. This prevents manipulation via price changes between quote and execution. 3. **Funding account private keys MUST only be used for subsidization transfers** — `getFundingAccount()` derives a keypair from `PENDULUM_FUNDING_SEED`. This keypair should only sign subsidization transfers, not arbitrary transactions. -4. **Final settlement subsidy MUST enforce a USD cap** — `MAX_FINAL_SETTLEMENT_SUBSIDY_USD` limits the maximum value the platform will subsidize per EVM settlement. **⚠️ CRITICAL BUG: This cap is NOT enforced — see below.** +4. **Final settlement subsidy MUST enforce a USD cap** — `MAX_FINAL_SETTLEMENT_SUBSIDY_USD` limits the maximum value the platform will subsidize per EVM settlement. 5. **Destination transfer MUST use a presigned transaction** — `destination-transfer-handler.ts` submits the presigned transfer from state. The server cannot modify the recipient address or amount at execution time. 6. **Destination transfer MUST verify balance before submission** — The handler checks that the ephemeral has sufficient balance for the transfer. If insufficient, the phase fails rather than submitting a transaction that would revert. 7. **Post-swap subsidization next-phase routing MUST be deterministic** — `subsidize-post-swap-handler.ts` contains branching logic that selects the next phase based on ramp direction (on/off), destination chain, and output token. This routing must be consistent with the flow defined at ramp creation. 8. **No subsidization handler MUST proceed if the funding account has insufficient balance** — If the funding account cannot cover the subsidy, the handler should fail with a recoverable error, not silently skip the top-up. +9. **EVM subsidy caps MUST stop transfers without forcing manual phase repair** — If an EVM pre/post-swap subsidy exceeds the quote-relative cap, the handler must not submit a transfer.

BRL / KYC Notes +11. Production Checklist + +The full suggested copy follows. + +--- + +# 1. Overview + +Vortex is a cross-chain ramping platform for moving between fiat currencies and crypto assets. It supports buy and sell flows across payment rails such as PIX and SEPA and blockchain networks such as Base, Polygon, Pendulum, Stellar, Moonbeam, AssetHub, and Hydration. + +These docs are intended for partner developers integrating Vortex into an application, backend, wallet, checkout flow, or operations dashboard. The endpoint reference documents the raw API surface, while the guide pages explain the recommended integration sequence and the responsibilities that sit on the API client side. + +For most integrations, Vortex recommends using `@vortexfi/sdk` instead of calling the ramp endpoints directly. The SDK wraps the quote and ramp lifecycle, creates fresh ephemeral accounts, signs required transactions, submits ramp updates, and can store local backups of ephemeral secrets. Direct API integrations are possible, but they must implement those responsibilities themselves. + +Vortex does not custody user private keys. During a ramp, temporary blockchain accounts called ephemeral accounts may hold funds in transit. Their public addresses are sent to Vortex, but their secret keys stay with the SDK or API client. This design keeps the signing boundary outside the Vortex API, but it also means the client must store the ephemeral secrets securely until the ramp has completed and any recovery window has passed. + +## Recommended Integration Paths + +Use the SDK when your application can run a trusted Node.js environment and wants Vortex to handle transaction signing and ramp update mechanics. + +Use the Widget when you want a hosted checkout experience and do not want to build the full user-facing ramp flow yourself. + +Use the raw API directly only when you need custom orchestration and are prepared to handle ephemeral key custody, signing, backups, ramp updates, and recovery flows yourself. + +--- + +# 2. Quick Start With The SDK + +Install the SDK: + +```bash +npm install @vortexfi/sdk +``` + +Initialize it: + +```ts +import { VortexSdk, FiatToken, EvmToken, Networks, RampDirection } from "@vortexfi/sdk"; + +const sdk = new VortexSdk({ + apiBaseUrl: "https://api.vortexfinance.co", + publicKey: "pk_live_...", + secretKey: "sk_live_...", + storeEphemeralKeys: true +}); +``` + +`publicKey` is used for partner attribution and partner-specific pricing. `secretKey` is sent as the `X-API-Key` header for partner-authenticated operations. Secret keys must only be used in trusted server-side environments. + +Create a quote: + +```ts +const quote = await sdk.createQuote({ + rampType: RampDirection.BUY, + from: "pix", + to: Networks.Polygon, + inputAmount: "150000", + inputCurrency: FiatToken.BRL, + outputCurrency: EvmToken.USDC +}); +``` + +Register the ramp: + +```ts +const { rampProcess } = await sdk.registerRamp(quote, { + destinationAddress: "0x1234567890123456789012345678901234567890", + taxId: "12345678900" +}); +``` + +For BRL buy flows, the ramp process may contain a PIX payment payload: + +```ts +console.log(rampProcess.depositQrCode); +``` + +After the user completes the fiat payment, start the ramp: + +```ts +const startedRamp = await sdk.startRamp(rampProcess.id); +``` + +Poll status or use webhooks: + +```ts +const status = await sdk.getRampStatus(rampProcess.id); +``` + +## Why The SDK Is Preferred + +The SDK creates fresh ephemeral accounts for each ramp, signs the transactions returned by Vortex, submits required update calls, and can store a local backup of ephemeral secrets. This removes several integration risks from partner applications. + +If you disable SDK key storage with `storeEphemeralKeys: false`, your application must provide an equivalent secure backup mechanism. + +--- + +# 3. Ramp Lifecycle + +Every Vortex ramp follows the same high-level lifecycle. + +## 1. Create A Quote + +Use `POST /v1/quotes` when the route and network are known. Use `POST /v1/quotes/best` when Vortex should evaluate eligible routes and return the best available quote for the requested amount and currency pair. + +A quote contains the input amount, expected output amount, source and destination, fee breakdown, payment method, network, and expiry. Quotes are short-lived and should be registered promptly. + +## 2. Register The Ramp + +Use `POST /v1/ramp/register` with the quote ID and the public addresses of the ephemeral accounts created for this ramp. The response returns a `rampId`, current ramp state, and any unsigned transactions that must be signed before processing can continue. + +Only public addresses are sent to Vortex. The matching ephemeral secret keys must stay with the SDK or API client. + +## 3. Update The Ramp + +Use `POST /v1/ramp/update` to submit signed transactions and route-specific transaction hashes. The SDK performs this automatically for supported flows. Direct API integrations must ensure that each signature or transaction hash matches the transaction returned by Vortex for the same ramp and phase. + +## 4. Start The Ramp + +Use `POST /v1/ramp/start` after required signatures, transaction hashes, and fiat payment steps are complete. For BRL buy flows, call start after the user completes the PIX payment. + +## 5. Track Status + +Use `GET /v1/ramp/{id}` to retrieve current state, or configure webhooks to receive lifecycle events asynchronously. + +Production integrations should persist the `quoteId`, `rampId`, partner order ID, user/session identifier, and any local ephemeral-key backup reference needed for support or recovery. + +--- + +# 4. Ephemeral Key Custody + +Ephemeral accounts are temporary blockchain accounts created for a single ramp. They may hold funds in transit while Vortex coordinates swaps, transfers, bridge operations, or payment settlement. + +Vortex receives only ephemeral public addresses. Vortex does not receive, store, log, or reconstruct ephemeral secret keys. + +This is a critical integration responsibility: + +- The API client or SDK environment must store ephemeral secrets securely. +- Secrets must remain available until the ramp is complete and any recovery window has passed. +- Secrets must never be sent to Vortex endpoints, support channels, logs, analytics, or browser-visible code. +- If ephemeral secrets are lost, Vortex may be unable to complete recovery or move funds on behalf of the user. + +The SDK can store local backups using `storeEphemeralKeys`, which defaults to `true`. In Node.js environments, these backups are written as local files keyed by ramp ID. + +Treat those backup files as sensitive key material. Encrypt them at rest in production, restrict filesystem permissions, exclude them from source control, and define a retention policy that matches your operational recovery needs. + +Direct API integrations must implement equivalent custody behavior. At minimum, they should create fresh ephemerals per ramp, store encrypted backups, associate backups with the ramp ID, and verify that recovery material exists before allowing the user to continue. + +--- + +# 5. Authentication And Partner Keys + +Vortex uses two partner key types. + +## Public Keys + +Public keys use the `pk_live_*` or `pk_test_*` prefix. They are used for partner attribution, tracking, and partner-specific quote behavior. Public keys may be included in SDK configuration or request bodies as `apiKey`. + +Public keys do not authenticate sensitive partner operations. + +## Secret Keys + +Secret keys use the `sk_live_*` or `sk_test_*` prefix. They authenticate partner operations through the `X-API-Key` header. + +Secret keys must be treated as server-side credentials. Do not expose them in browser bundles, mobile app binaries, URLs, screenshots, analytics tools, logs, or support tickets. + +When a request includes `partnerId`, the API may require the secret key to authenticate the matching partner. If the authenticated partner does not match the requested partner, Vortex rejects the request. + +## Recommended Handling + +Store secret keys in a secret manager or encrypted environment configuration. Rotate keys if they are exposed, no longer needed, or tied to a retired integration. Use test keys in sandbox and live keys only in production. + +--- + +# 6. Quotes And Pricing + +Quotes are the entry point for ramp execution. A quote defines the route, amount, fees, expected output, payment method, network, and expiry. + +Use `POST /v1/quotes` when you know the route and network. Use `POST /v1/quotes/best` when you want Vortex to compare eligible routes and select the best available quote. + +The quote response includes fee fields in fiat and USD terms. These may include network fees, anchor/provider fees, Vortex fees, partner fees, total fees, and processing fees. + +Quotes should be treated as immutable. After a quote is created, use the quote ID to register a ramp. Do not assume a quote remains valid indefinitely. If a quote expires, create a fresh quote. + +For partner pricing and attribution, pass the partner public key as `apiKey`. If the request includes `partnerId`, authenticate with the matching partner secret key in `X-API-Key`. + +--- + +# 7. Webhooks + +Webhooks let partner systems receive transaction lifecycle events without continuously polling the ramp status endpoint. + +Register a webhook: + +```http +POST /v1/webhook +X-API-Key: sk_live_... +Content-Type: application/json +``` + +```json +{ + "url": "https://partner.example.com/vortex/webhook", + "quoteId": "quote_...", + "events": ["TRANSACTION_CREATED", "STATUS_CHANGE"] +} +``` + +Webhook URLs must use HTTPS. Store the returned webhook ID so that the endpoint can be deleted later. + +Delete a webhook: + +```http +DELETE /v1/webhook/{id} +X-API-Key: sk_live_... +``` + +## Verification + +Verify every webhook before trusting it. Fetch the current public key: + +```http +GET /v1/public-key +``` + +Use the returned public key to verify webhook signatures. Reject requests that fail signature verification, contain malformed payloads, or do not match the expected event structure. + +Polling `GET /v1/ramp/{id}` is still useful for user-facing status screens, but webhooks are preferable for reconciliation, back-office automation, and support workflows. + +--- + +# 8. Widget Integration + +The Vortex Widget provides a hosted checkout experience for buy and sell flows. It is useful when you want Vortex to handle more of the user-facing ramp flow instead of building the complete SDK experience yourself. + +The widget supports two quote modes. + +## Auto-Refresh Mode + +In auto-refresh mode, the widget creates and refreshes quotes based on the requested direction, amount, fiat currency, crypto asset, network, and payment method. + +Use this when your application wants the user to complete checkout from a route definition rather than from a pre-selected quote. + +## Fixed-Quote Mode + +In fixed-quote mode, your application creates a quote first and passes the `quoteId` to the widget. The widget uses that quote for checkout. + +Fixed quotes do not refresh automatically. If the quote expires, the user must restart from a fresh quote. + +## When To Use The Widget + +Use the Widget when you want a hosted UX and less direct orchestration. Use the SDK when you want to own the UX but still want Vortex to handle transaction signing and ramp update mechanics. Use the raw API only when you need a custom backend integration and can handle ephemeral key custody yourself. + +--- + +# 9. Sandbox + +Use the sandbox environment to test quote creation, ramp registration, signing, updates, webhook handling, and status tracking without touching production funds. + +Vortex UI: + +```text +https://sandbox.vortexfinance.co +``` + +SDK/API base URL: + +```text +https://api-sandbox.vortexfinance.co +``` + +Use test keys in sandbox. Do not use production API keys, production wallets, production private keys, or production user data. + +For EVM-based test flows, use your own test wallet and fund it from public testnet faucets. Do not publish shared recovery phrases or reuse them in partner applications, CI logs, screenshots, or documentation. + +Sandbox flows may complete faster than production flows and may mock parts of payment or KYC behavior. Production integrations should still handle asynchronous confirmations, delayed status changes, recoverable failures, webhook retries, and user support workflows. + +--- + +# 10. BRL / KYC Notes + +BRL routes require user onboarding with Vortex's local payment partner before ramping. The user's Brazilian tax ID, either CPF for individuals or CNPJ for businesses, is used as the primary identifier. + +Level 1 onboarding collects basic identity information and enables lower-limit BRL flows. Level 2 adds document and liveness verification and may be required for higher limits or stricter compliance rules. + +The SDK ramp flow assumes that the user is eligible for the selected corridor. If the user has not completed the required onboarding, the ramp may fail or require additional account-management steps. + +KYC endpoints are available for account-management integrations, but they should not be treated as the primary SDK ramp flow. When possible, use the Vortex application or a dedicated onboarding flow to complete KYC before ramp execution. + +--- + +# 11. Production Checklist + +Before going live, verify the following: + +- Use the SDK unless you have a clear reason to integrate directly with the raw API. +- Store secret API keys only in trusted server-side environments. +- Never expose `sk_live_*` or `sk_test_*` keys in browser or mobile code. +- Store ephemeral account secrets securely until ramps complete and recovery is no longer needed. +- Encrypt ephemeral-key backups at rest in production. +- Persist `quoteId`, `rampId`, user/session ID, partner order ID, and webhook IDs. +- Handle quote expiry by creating fresh quotes. +- Use webhooks for transaction lifecycle events and verify every webhook signature. +- Poll `GET /v1/ramp/{id}` for user-facing status screens. +- Test failed, delayed, and retried ramp states in sandbox. +- Define a support process for users who close the app before a ramp finishes. +- Rotate partner keys if they are exposed or no longer needed. + +Direct API integrations should also verify that their signing implementation only signs the transactions returned by Vortex for the current ramp and phase. Never sign arbitrary transaction payloads without validating their destination, amount, asset, network, and signer.

It supports buy and sell flows across payment rails such as PIX and blockchain networks such as Base, Polygon, Pendulum, Stellar, Moonbeam, AssetHub, and Hydration. These docs are intended for partner developers integrating Vortex into an application, backend, wallet, checkout flow, or operations dashboard. The endpoint reference documents the raw API surface, while the guide pages explain the recommended integration sequence and the responsibilities that sit on the API client side. For most integrations, Vortex recommends using `@vortexfi/sdk` instead of calling the ramp endpoints directly. The SDK wraps the quote and ramp lifecycle, creates fresh ephemeral accounts, signs required transactions, submits ramp updates, and can store local backups of ephemeral secrets.

It supports buy and sell flows across payment rails such as PIX and blockchain networks such as Base, Polygon, Pendulum, Stellar, Moonbeam, AssetHub, and Hydration. These docs are intended for partner developers integrating Vortex into an application, backend, wallet, checkout flow, or operations dashboard. The endpoint reference documents the raw API surface, while the guide pages explain the recommended integration sequence and the responsibilities that sit on the API client side. For most integrations, Vortex recommends using `@vortexfi/sdk` instead of calling the ramp endpoints directly. The SDK wraps the quote and ramp lifecycle, creates fresh ephemeral accounts, signs required transactions, submits ramp updates, and can store local backups of ephemeral secrets. Direct API integrations are possible, but they must implement those responsibilities themselves. +The current SDK release is intended for trusted Node.js environments. Browser support is not enabled. SEPA paths are present in parts of the API surface, but the current SDK flow is centered on BRL/PIX support. + Vortex does not custody user private keys. During a ramp, temporary blockchain accounts called ephemeral accounts may hold funds in transit. Their public addresses are sent to Vortex, but their secret keys stay with the SDK or API client. This design keeps the signing boundary outside the Vortex API, but it also means the client must store the ephemeral secrets securely until the ramp has completed and any recovery window has passed. ## Recommended Integration Paths diff --git a/docs/api/pages/02-quick-start-with-the-sdk.md b/docs/api/pages/02-quick-start-with-the-sdk.md index 5ff0543e6..fd61c38d9 100644 --- a/docs/api/pages/02-quick-start-with-the-sdk.md +++ b/docs/api/pages/02-quick-start-with-the-sdk.md @@ -10,16 +10,19 @@ Initialize it: ```ts import { VortexSdk, FiatToken, EvmToken, Networks, RampDirection } from "@vortexfi/sdk"; +import type { VortexSdkConfig } from "@vortexfi/sdk"; -const sdk = new VortexSdk({ +const config: VortexSdkConfig = { apiBaseUrl: "https://api.vortexfinance.co", publicKey: "pk_live_...", secretKey: "sk_live_...", storeEphemeralKeys: true -}); +}; + +const sdk = new VortexSdk(config); ``` -`publicKey` is used for partner attribution and partner-specific pricing. `secretKey` is sent as the `X-API-Key` header for partner-authenticated operations.

Partners use this key to verify the signature on webhook deliveries. - -## Security And Copy Requirements - -The following warnings should be prominent in partner docs: - -- Vortex never receives, stores, logs, or reconstructs ephemeral account secret keys. Only public addresses are sent to the API during ramp registration. -- The API client or SDK environment is responsible for storing ephemeral account secrets securely. -- If ephemeral secrets are lost before a ramp completes, Vortex may be unable to complete the ramp or move funds on behalf of the user. (Vortex does have chain-specific cleanup mechanisms that can recover funds in some cases, but partners should not rely on this for normal operation.) -- The Vortex SDK is strongly preferred because it creates ephemeral accounts, signs required transactions, submits update calls, and can store local backups. -- Direct API integrations must implement key custody, signing, update calls, and recovery backup behavior themselves. -- Secret API keys (`sk_live_*`, `sk_test_*`) must only be used server-side. -- Public API keys (`pk_live_*`, `pk_test_*`) are for attribution/tracking, not authentication. -- Webhook payloads should be verified against the RSA-PSS signature using the key from `GET /v1/public-key`. - -## Sensitive Information Checks - -Before import or publication, scan generated artifacts for: - -```bash -rg -n --pcre2 '(adgp_[A-Za-z0-9]+|sk_(live|test)_[A-Za-z0-9]{12,}|pk_(live|test)_[A-Za-z0-9]{12,}|recovery phrase:\s*`[^`]+`|mnemonic:\s*`[^`]+`|seed phrase:\s*`[^`]+`|-----BEGIN (RSA |EC |OPENSSH |)PRIVATE KEY-----)' -``` - -The public Sandbox page previously exposed a shared test wallet recovery phrase. Remove it from any rewritten copy and replace it with safer guidance to use partner-owned test wallets and public faucets. - -Example placeholders such as `sk_live_...` and `pk_live_...` are acceptable. Real keys are not. - -## Useful Local Artifacts From The Previous Pass - -These files were generated during the previous docs pass. They may still exist on the local machine, but do not assume they are permanent: - -```text -/private/tmp/apidog-project-918521-export.json -/private/tmp/apidog-project-918521-pre-docs-refactor-2026-05-15.json -/private/tmp/vortex-apidog-preserve-existing-draft.json -/private/tmp/vortex-apidog-informational-pages-rewrite.md -/private/tmp/vortex-apidog-text-pages-proposal.md -``` - -> The local OpenAPI draft from the previous pass preserved all 22 first-draft paths, but two of those paths (`startKYC2`, `getOfframpStatus`) do not exist in code. A re-import based on that draft would put Apidog out of sync with reality. **Do not import the previous draft as-is.** Regenerate against the 25-path scope above. - -## Suggested Pure Text Page Structure - -Recommended Apidog Markdown pages: - -1.

BRL / KYC Notes -11. Production Checklist - -The full suggested copy follows. Code samples have been verified against the current SDK source (`packages/sdk/src/VortexSdk.ts`, `packages/sdk/src/services/ApiService.ts`). - ---- - -# 1. Overview - -Vortex is a cross-chain ramping platform for moving between fiat currencies and crypto assets. It supports buy and sell flows across payment rails such as PIX and blockchain networks such as Base, Polygon, Pendulum, Stellar, Moonbeam, AssetHub, and Hydration. - -These docs are intended for partner developers integrating Vortex into an application, backend, wallet, checkout flow, or operations dashboard. The endpoint reference documents the raw API surface, while the guide pages explain the recommended integration sequence and the responsibilities that sit on the API client side. - -For most integrations, Vortex recommends using `@vortexfi/sdk` instead of calling the ramp endpoints directly. The SDK wraps the quote and ramp lifecycle, creates fresh ephemeral accounts, signs required transactions, submits ramp updates, and can store local backups of ephemeral secrets. Direct API integrations are possible, but they must implement those responsibilities themselves. - -> **SDK environment**: The current SDK release runs in Node.js only. Browser support is not enabled. -> **SEPA flows**: SEPA on/off-ramp paths are stubbed in the SDK (`registerRamp` throws "not implemented yet" for SEPA quotes). BRL flows via PIX are the supported SDK path today. - -Vortex does not custody user private keys. During a ramp, temporary blockchain accounts called ephemeral accounts may hold funds in transit. Their public addresses are sent to Vortex, but their secret keys stay with the SDK or API client. This design keeps the signing boundary outside the Vortex API, but it also means the client must store the ephemeral secrets securely until the ramp has completed and any recovery window has passed. - -## Recommended Integration Paths - -Use the SDK when your application can run a trusted Node.js environment and wants Vortex to handle transaction signing and ramp update mechanics. - -Use the Widget when you want a hosted checkout experience and do not want to build the full user-facing ramp flow yourself. - -Use the raw API directly only when you need custom orchestration and are prepared to handle ephemeral key custody, signing, backups, ramp updates, and recovery flows yourself. - ---- - -# 2. Quick Start With The SDK - -Install the SDK: - -```bash -npm install @vortexfi/sdk -``` - -Initialize it: - -```ts -import { VortexSdk, FiatToken, EvmToken, Networks, RampDirection } from "@vortexfi/sdk"; -import type { VortexSdkConfig } from "@vortexfi/sdk"; - -const config: VortexSdkConfig = { - apiBaseUrl: "https://api.vortexfinance.co", - publicKey: "pk_live_...", // optional today; required after grace period - secretKey: "sk_live_...", // optional today; required after grace period - storeEphemeralKeys: true // default -}; - -const sdk = new VortexSdk(config); -``` - -`publicKey` is attached to quote requests for partner attribution and discount eligibility. `secretKey` is sent as the `X-API-Key` header on every request and authenticates the partner. Secret keys must only be used in trusted server-side environments. - -Create a quote (BRL → USDC on Polygon, via PIX): - -```ts -const quote = await sdk.createQuote({ - rampType: RampDirection.BUY, - from: "pix", - to: Networks.Polygon, - inputAmount: "150000", - inputCurrency: FiatToken.BRL, - outputCurrency: EvmToken.USDC -}); -``` - -Register the ramp: - -```ts -const { rampProcess } = await sdk.registerRamp(quote, { - destinationAddress: "0x1234567890123456789012345678901234567890", - taxId: "12345678900" -}); -``` - -For BRL buy flows, the ramp process contains a PIX payment payload: - -```ts -console.log(rampProcess.depositQrCode); -``` - -After the user completes the fiat payment, start the ramp. `startRamp` takes only the ramp ID: - -```ts -const startedRamp = await sdk.startRamp(rampProcess.id); -``` - -Poll status or use webhooks: - -```ts -const status = await sdk.getRampStatus(rampProcess.id); -``` - -## Why The SDK Is Preferred - -The SDK creates fresh ephemeral accounts for each ramp (one each on Stellar, Pendulum, and Moonbeam), signs the transactions returned by Vortex, submits required update calls, and can store a local backup of ephemeral secrets. This removes several integration risks from partner applications. - -If you disable SDK key storage with `storeEphemeralKeys: false`, your application must provide an equivalent secure backup mechanism. - -> The default local backup is a JSON file named `ephemerals_{rampId}.json` written to the Node process's current working directory. It is not encrypted at rest. For production, run the SDK from a directory with restricted filesystem permissions, encrypt the file yourself, or disable `storeEphemeralKeys` and implement a custom store. - ---- - -# 3. Ramp Lifecycle - -Every Vortex ramp follows the same high-level lifecycle. - -## 1. Create A Quote - -Use `POST /v1/quotes` when the route and network are known. Use `POST /v1/quotes/best` when Vortex should evaluate eligible routes and return the best available quote for the requested amount and currency pair. - -A quote contains the input amount, expected output amount, source and destination, fee breakdown, payment method, network, and expiry. Quotes are short-lived and should be registered promptly. - -`POST /v1/quotes/best` is not called by the SDK today. To use it, call the raw API directly with the same body shape as `POST /v1/quotes` (plus optional `countryCode`) and pass the returned quote into `sdk.registerRamp(...)`. - -## 2. Register The Ramp - -Use `POST /v1/ramp/register` with the quote ID and the public addresses of the ephemeral accounts created for this ramp. The response returns a `rampId`, current ramp state, and any unsigned transactions that must be signed before processing can continue. - -Only public addresses are sent to Vortex. The matching ephemeral secret keys must stay with the SDK or API client. - -## 3. Update The Ramp - -Use `POST /v1/ramp/update` to submit signed transactions and route-specific transaction hashes. - -The SDK performs this automatically for supported flows. Note that on BRL buy flows the SDK calls `POST /v1/ramp/update` **inside** `registerRamp` to submit the presigned transactions; there is no separate `updateRamp` step for buys. On sells, `sdk.updateRamp(quote, rampId, { ... })` is used to submit additional route-specific transaction hashes after off-chain steps complete. - -Direct API integrations must ensure that each signature or transaction hash matches the transaction returned by Vortex for the same ramp and phase. - -## 4. Start The Ramp - -Use `POST /v1/ramp/start` after required signatures, transaction hashes, and fiat payment steps are complete. For BRL buy flows, call start after the user completes the PIX payment. - -## 5. Track Status - -Use `GET /v1/ramp/{id}` to retrieve current state, or configure webhooks to receive lifecycle events asynchronously. `GET /v1/ramp/{id}/errors` returns the error log for a ramp and is useful for support tooling. - -Production integrations should persist the `quoteId`, `rampId`, partner order ID, user/session identifier, and any local ephemeral-key backup reference needed for support or recovery. - ---- - -# 4. Ephemeral Key Custody - -Ephemeral accounts are temporary blockchain accounts created for a single ramp. The SDK creates up to three per ramp — one Stellar, one Substrate (Pendulum), one EVM (Moonbeam). They may hold funds in transit while Vortex coordinates swaps, transfers, bridge operations, or payment settlement. - -Vortex receives only ephemeral public addresses. Vortex does not receive, store, log, or reconstruct ephemeral secret keys. - -This is a critical integration responsibility: - -- The API client or SDK environment must store ephemeral secrets securely. -- Secrets must remain available until the ramp is complete and any recovery window has passed. -- Secrets must never be sent to Vortex endpoints, support channels, logs, analytics, or browser-visible code. -- If ephemeral secrets are lost, the partner may be unable to complete recovery for that ramp. Vortex has chain-specific cleanup workers that can sweep some residual funds, but partners should not rely on this as a primary recovery mechanism. - -The SDK can store local backups using `storeEphemeralKeys`, which defaults to `true`. In Node.js environments, the SDK writes `ephemerals_{rampId}.json` to the process's current working directory. The file is not encrypted at rest and the path is not configurable in the current release. - -Treat those backup files as sensitive key material. Encrypt them at rest in production, restrict filesystem permissions, exclude them from source control, and define a retention policy that matches your operational recovery needs. Or, set `storeEphemeralKeys: false` and implement an equivalent secure backup mechanism. - -Direct API integrations must implement equivalent custody behavior. At minimum, they should create fresh ephemerals per ramp, store encrypted backups, associate backups with the ramp ID, and verify that recovery material exists before allowing the user to continue. - ---- - -# 5. Authentication And Partner Keys - -Vortex authenticates partners with two key types and accepts a third principal (Supabase Bearer) for first-party user flows. - -## Public Keys - -Public keys use the `pk_live_*` or `pk_test_*` prefix. They are used for partner attribution, tracking, and partner-specific quote behavior. Public keys may be included in SDK configuration, in request bodies as `apiKey`, or in the `?apiKey=` query string. - -Public keys do not authenticate sensitive partner operations. An invalid or expired public key, however, is rejected with HTTP 401 on routes that validate it — it is not silently ignored. - -## Secret Keys - -Secret keys use the `sk_live_*` or `sk_test_*` prefix. They authenticate partner operations through the `X-API-Key` header. - -Secret keys must be treated as server-side credentials. Do not expose them in browser bundles, mobile app binaries, URLs, screenshots, analytics tools, logs, or support tickets. - -When a request includes `partnerId` (in quote creation), the API requires a matching secret key in `X-API-Key`. `partnerId` may be either the partner's UUID or its name; matching is performed by partner name. If the authenticated partner does not match the requested partner, Vortex rejects the request with HTTP 403. - -Ramp endpoints (`/v1/ramp/register`, `/update`, `/start`, `GET /v1/ramp/{id}`, history, errors) require authentication unconditionally — either an `sk_*` key OR a Supabase Bearer token. Anonymous requests are rejected with HTTP 401. - -Webhook endpoints require `sk_*` and do not accept Supabase Bearer tokens. - -## Supabase Bearer tokens - -Some endpoints — currently `/v1/brla/*` — accept only Supabase Bearer tokens, not `sk_*`. These are intended for first-party flows where the end user has authenticated with Vortex directly. Partner SDK integrations cannot drive BRL KYC through these endpoints with only `sk_*` / `pk_*`; the user must complete onboarding through the Vortex application or hosted widget first. - -## Recommended Handling - -Store secret keys in a secret manager or encrypted environment configuration. Rotate keys if they are exposed, no longer needed, or tied to a retired integration. Use test keys in sandbox and live keys only in production. - ---- - -# 6. Quotes And Pricing - -Quotes are the entry point for ramp execution. A quote defines the route, amount, fees, expected output, payment method, network, and expiry. - -Use `POST /v1/quotes` when you know the route and network. Use `POST /v1/quotes/best` when you want Vortex to compare eligible routes and select the best available quote. `GET /v1/quotes/{id}` is fully public — anyone with a quote ID can read it. Do not treat quote IDs as confidential, but do not expose them in URLs unnecessarily. - -The quote response from `/v1/quotes/best` includes fee fields in fiat and USD terms (network, anchor, Vortex, partner, total, processing). The same fields are available on standard quotes where applicable. - -Quotes should be treated as immutable. After a quote is created, use the quote ID to register a ramp. Do not assume a quote remains valid indefinitely. If a quote expires, create a fresh quote. - -For partner pricing and attribution, pass the partner public key as `apiKey` in the request body. If the request includes `partnerId`, authenticate with the matching partner secret key in `X-API-Key`. - ---- - -# 7. Webhooks - -Webhooks let partner systems receive transaction lifecycle events without continuously polling the ramp status endpoint. - -Register a webhook against either a quote or a widget session: - -```http -POST /v1/webhook -X-API-Key: sk_live_... -Content-Type: application/json -``` - -```json -{ - "url": "https://partner.example.com/vortex/webhook", - "quoteId": "quote_...", - "events": ["TRANSACTION_CREATED", "STATUS_CHANGE"] -} -``` - -The request body must include exactly one of `quoteId` or `sessionId`. Use `sessionId` when subscribing to events from a widget-hosted ramp instead of a partner-created quote. - -Webhook URLs must use HTTPS. Store the returned webhook ID so that the endpoint can be deleted later. - -Delete a webhook: - -```http -DELETE /v1/webhook/{id} -X-API-Key: sk_live_... -``` - -## Verification - -Verify every webhook before trusting it. Fetch the current public key: - -```http -GET /v1/public-key -``` - -The endpoint returns an RSA-PSS 2048-bit public key in PEM format. Vortex signs every webhook payload with the corresponding private key. Verify the signature on each delivery using `RSA-PSS` with `SHA-256` and the key from this endpoint. Reject requests that fail signature verification, contain malformed payloads, or do not match the expected event structure. - -Polling `GET /v1/ramp/{id}` is still useful for user-facing status screens, but webhooks are preferable for reconciliation, back-office automation, and support workflows. - ---- - -# 8. Widget Integration - -The Vortex Widget provides a hosted checkout experience for buy and sell flows. It is useful when you want Vortex to handle more of the user-facing ramp flow instead of building the complete SDK experience yourself. - -Widget sessions are created via `POST /v1/session/create`, which accepts an `apiKey` (`pk_*`) in the body for attribution. No secret key is required to create a session. - -The widget supports two quote modes. - -## Auto-Refresh Mode - -In auto-refresh mode, the widget creates and refreshes quotes based on the requested direction, amount, fiat currency, crypto asset, network, and payment method. - -Use this when your application wants the user to complete checkout from a route definition rather than from a pre-selected quote. - -## Fixed-Quote Mode - -In fixed-quote mode, your application creates a quote first and passes the `quoteId` to the widget. The widget uses that quote for checkout. - -Fixed quotes do not refresh automatically. If the quote expires, the user must restart from a fresh quote. - -## When To Use The Widget - -Use the Widget when you want a hosted UX and less direct orchestration. Use the SDK when you want to own the UX but still want Vortex to handle transaction signing and ramp update mechanics. Use the raw API only when you need a custom backend integration and can handle ephemeral key custody yourself. - ---- - -# 9. Sandbox - -Use the sandbox environment to test quote creation, ramp registration, signing, updates, webhook handling, and status tracking without touching production funds. - -Vortex UI: - -```text -https://sandbox.vortexfinance.co -``` - -SDK/API base URL: - -```text -https://api-sandbox.vortexfinance.co -``` - -Use test keys (`pk_test_*`, `sk_test_*`) in sandbox. Do not use production API keys, production wallets, production private keys, or production user data. - -For EVM-based test flows, use your own test wallet and fund it from public testnet faucets. Do not publish shared recovery phrases or reuse them in partner applications, CI logs, screenshots, or documentation. - -Sandbox flows may complete faster than production flows and may mock parts of payment or KYC behavior. Production integrations should still handle asynchronous confirmations, delayed status changes, recoverable failures, webhook retries, and user support workflows. - ---- - -# 10. BRL / KYC Notes - -BRL routes require user onboarding with Vortex's local payment partner before ramping. The user's Brazilian tax ID, either CPF for individuals or CNPJ for businesses, is used as the primary identifier. - -Level 1 onboarding collects basic identity information and enables lower-limit BRL flows. Level 2 adds document and liveness verification and may be required for higher limits or stricter compliance rules. - -The SDK ramp flow assumes the user is eligible for the selected corridor. If the user has not completed the required onboarding, the ramp may fail or require additional account-management steps. - -> **Partner integrations cannot drive BRLA KYC directly with `sk_*` / `pk_*` keys.** All `/v1/brla/*` endpoints require a Supabase Bearer token representing an authenticated end user. Use the Vortex application or hosted widget to complete onboarding, or design your integration so users complete KYC before your partner backend triggers a ramp. - -KYC endpoints are documented for first-party flows and account-management integrations. They should not be treated as the primary SDK ramp flow. - ---- - -# 11. Production Checklist - -Before going live, verify the following: - -- Use the SDK unless you have a clear reason to integrate directly with the raw API. -- Store secret API keys only in trusted server-side environments. -- Never expose `sk_live_*` or `sk_test_*` keys in browser or mobile code. -- Store ephemeral account secrets securely until ramps complete and recovery is no longer needed. -- If using the SDK's default `storeEphemeralKeys: true`, run the SDK from a directory with restricted filesystem permissions, or set `storeEphemeralKeys: false` and implement encrypted local storage. -- Persist `quoteId`, `rampId`, user/session ID, partner order ID, and webhook IDs. -- Handle quote expiry by creating fresh quotes. -- Use webhooks for transaction lifecycle events and verify every webhook signature against `GET /v1/public-key` (RSA-PSS / SHA-256). -- Poll `GET /v1/ramp/{id}` for user-facing status screens and `GET /v1/ramp/{id}/errors` for support tooling. -- Test failed, delayed, and retried ramp states in sandbox. -- Define a support process for users who close the app before a ramp finishes. -- Rotate partner keys if they are exposed or no longer needed. -- For BRL flows: confirm your user onboarding path produces a Supabase-authenticated user before invoking the ramp. - -Direct API integrations should also verify that their signing implementation only signs the transactions returned by Vortex for the current ramp and phase. Never sign arbitrary transaction payloads without validating their destination, amount, asset, network, and signer.

Overview -Vortex is a cross-chain ramping platform for moving between fiat currencies and crypto assets. It supports buy and sell flows across payment rails such as PIX and blockchain networks such as Base, Polygon, Pendulum, Stellar, Moonbeam, AssetHub, and Hydration. +Vortex is a cross-border payments gateway that moves value between fiat currencies and crypto assets. It coordinates quoting, cross-chain swaps via XCM, anchor settlement, and payout across networks such as Base, Polygon, Ethereum, Arbitrum, BSC, Avalanche, Pendulum, Stellar, Moonbeam, AssetHub, and Hydration. -These docs are intended for partner developers integrating Vortex into an application, backend, wallet, checkout flow, or operations dashboard. The endpoint reference documents the raw API surface, while the guide pages explain the recommended integration sequence and the responsibilities that sit on the API client side. +These docs are written for partner developers integrating Vortex into a backend, wallet, checkout flow, or operations dashboard. The endpoint reference documents the raw API surface; the guide pages explain the recommended integration sequence and the responsibilities that sit on the API client side. -For most integrations, Vortex recommends using `@vortexfi/sdk` instead of calling the ramp endpoints directly. The SDK wraps the quote and ramp lifecycle, creates fresh ephemeral accounts, signs required transactions, submits ramp updates, and can store local backups of ephemeral secrets. Direct API integrations are possible, but they must implement those responsibilities themselves. +## Supported Corridors -The current SDK release is intended for trusted Node.js environments. Browser support is not enabled. SEPA paths are present in parts of the API surface, but the current SDK flow is centered on BRL/PIX support. +The current SDK release is centered on **BRL/PIX** for both buy (onramp) and sell (offramp) flows. EUR onramp endpoints exist on the API surface but the SDK throws `"Euro onramp handler not implemented yet"`; SEPA buy flows are not production-ready today. Other fiat currencies are exposed through reference data endpoints and are added incrementally. -Vortex does not custody user private keys. During a ramp, temporary blockchain accounts called ephemeral accounts may hold funds in transit. Their public addresses are sent to Vortex, but their secret keys stay with the SDK or API client. This design keeps the signing boundary outside the Vortex API, but it also means the client must store the ephemeral secrets securely until the ramp has completed and any recovery window has passed. +For crypto, Vortex supports USDC and USDT across the listed EVM networks plus USDC on AssetHub. Stablecoin pegs and routes are subject to liquidity on the Nabla AMM and the wider Pendulum/Hydration corridor. + +## How A Ramp Flows + +Every Vortex ramp follows the same shape: + +1. **Quote** — your application requests pricing for a route. +2. **Register** — your application creates per-chain ephemeral accounts and submits their public addresses with the quote ID. Vortex returns one or more **unsigned** transactions that move funds through the ramp. +3. **Sign and update** — your application signs each unsigned transaction with the correct key (ephemeral key for SDK-controlled accounts, user wallet for the user's funds) and submits the signed payloads back to Vortex. +4. **Settle fiat** — for BRL buys, the user pays a PIX QR; for BRL sells, Vortex pays out to the user's PIX key after settlement. +5. **Start** — your application calls start once signatures and fiat payment are in place. +6. **Track** — Vortex drives the on-chain phase machine. Your application listens via webhooks or polls the ramp status endpoint. + +The SDK wraps steps 2, 3, and parts of 5 for supported flows. Direct API integrations must implement them explicitly. ## Recommended Integration Paths -Use the SDK when your application can run a trusted Node.js environment and wants Vortex to handle transaction signing and ramp update mechanics. +| Stack / use case | Recommended path | +|---|---| +| Trusted Node.js backend | `@vortexfi/sdk` | +| Python backend | `vortex-sdk-python` (process-bridge wrapper around the Node SDK) | +| Browser / mobile / hosted checkout | Vortex Widget | +| Any other language or runtime | Direct API integration following the SDK's behavior | + +The SDK is intended for **trusted server-side Node.js** only. Browser support is not enabled. For browser-driven UX, embed the Widget instead of calling the API directly from the browser. + +## Custody Model + +Vortex does not custody user private keys. During a ramp, short-lived blockchain accounts called **ephemeral accounts** hold funds in transit. Vortex receives their public addresses; their secret keys never leave the SDK or your API client. + +This boundary is non-negotiable: if ephemeral secrets are lost while a ramp is in flight, recovery may be impossible for that ramp.

Retries must not produce duplicate ramps. +4. **Retries with backoff.** The Vortex SDK does not retry, time out, or poll on your behalf. Add a retry policy with jittered exponential backoff for transient failures (5xx, network) and surface 4xx errors as terminal. +5. **Quote-expiry handling.** Catch expiry errors on `register`. Create a fresh quote and re-prompt the user. +6. **Webhook signature verification.** Reject any webhook that fails RSA-PSS verification or whose `X-Vortex-Timestamp` is outside an acceptable window (300s is a reasonable default). +7. **HTTPS-only webhook endpoints.** Plain HTTP is rejected. +8. **Persistent state.** Persist `quoteId`, `rampId`, `sessionId`, partner order ID, user identifier, webhook IDs, and a reference to the ephemeral-key backup. Without these you cannot support users or reconcile. +9. **Type safety on amounts.** All monetary fields are decimal strings. Do not parse to float; use a decimal library (e.g. `BigDecimal`, `decimal.Decimal`). +10. **WebSocket lifecycle (if applicable).** If you mirror the SDK's chain-side behavior, expect to maintain Pendulum, Moonbeam, and Hydration WebSocket connections. Reuse one client per process; do not open a new connection per request. +11. **Sandbox / production isolation.** Use `pk_test_*` / `sk_test_*` against `api-sandbox.vortexfinance.co`. Never mix test keys with the live base URL or vice versa. + +## F. Things The SDK Does Not Do (And Neither Should A Custom Client Pretend To) + +- It does not retry failed HTTP requests. +- It does not poll ramp status; you must poll or use webhooks. +- It does not encrypt ephemeral backups at rest. +- It does not delete ephemeral backups after success. +- It does not drive BRLA KYC; the user must be onboarded through the Vortex app or Widget before a BRL ramp. +- It does not support EUR onramp today (throws `"Euro onramp handler not implemented yet"`). + +Mirror those gaps deliberately.

From 9bf1f338e3ef5265f115601add97c7cf75423c6e Mon Sep 17 00:00:00 2001 From: Marcel Ebert Date: Tue, 19 May 2026 20:07:13 +0200 Subject: [PATCH 81/90] Reject user-wallet presigned txs and verify SELL squid hashes on-chain User-wallet phases (moneriumOnrampMint, SELL squidRouterApprove/Swap, squidRouterNoPermit{Approve,Swap,Transfer}) previously fell through validatePresignedTxs via 'continue', which allowed a malicious client to attach an unrelated presigned tx labeled with one of these phase names without any content validation. Flip the skip to a BAD_REQUEST reject and direct integrators to submit only the on-chain tx hash via additionalData. Add verifyUserSubmittedTxByHash helper that resolves the receipt and transaction by hash, then binds receipt.from, tx.to, tx.input, tx.value to the server-issued unsigned payload (blueprint.signer + blueprint.txData). Refactor squidrouter-permit-execution-handler.waitForUserHash to delegate to the helper, and add verifyUserSubmittedSquidHashes at the top of FundEphemeralPhaseHandler.executePhase so SELL standard EVM offramps verify squidRouterApprove + squidRouterSwap on-chain before any ephemeral funding occurs. This closes the F-041 gap where SELL squid hashes were neither validated as presigned txs nor verified at runtime. Update validation.test.ts: replace 3 skip-tests with 5 reject-tests covering each user-wallet phase, plus a positive test confirming BUY squidRouterSwap still validates as ephemeral-signed. All 50 validation tests pass. Update docs/security-spec/03-ramp-engine/transaction-validation.md to document the two-layer model (reject + by-hash verification), mark F-041 as MITIGATED, and add a threat row for user-wallet phase presigned-tx smuggling. --- .../phases/handlers/fund-ephemeral-handler.ts | 32 ++++++++ .../squidrouter-permit-execution-handler.ts | 46 ++---------- .../phases/helpers/user-tx-verifier.ts | 73 +++++++++++++++++++ .../services/transactions/validation.test.ts | 51 +++++++++++-- .../api/services/transactions/validation.ts | 14 +++- .../03-ramp-engine/transaction-validation.md | 22 ++++-- 6 files changed, 180 insertions(+), 58 deletions(-) create mode 100644 apps/api/src/api/services/phases/helpers/user-tx-verifier.ts diff --git a/apps/api/src/api/services/phases/handlers/fund-ephemeral-handler.ts b/apps/api/src/api/services/phases/handlers/fund-ephemeral-handler.ts index 88f2225e1..fd39d4a9b 100644 --- a/apps/api/src/api/services/phases/handlers/fund-ephemeral-handler.ts +++ b/apps/api/src/api/services/phases/handlers/fund-ephemeral-handler.ts @@ -27,6 +27,7 @@ import { fundEphemeralAccount } from "../../pendulum/pendulum.service"; import { BasePhaseHandler } from "../base-phase-handler"; import { getEvmFundingAccount } from "../evm-funding"; import { validateStellarPaymentSequenceNumber } from "../helpers/stellar-sequence-validator"; +import { verifyUserSubmittedTxByHash } from "../helpers/user-tx-verifier"; import { StateMetadata } from "../meta-state-types"; import { DESTINATION_EVM_FUNDING_AMOUNTS, @@ -110,12 +111,43 @@ export class FundEphemeralPhaseHandler extends BasePhaseHandler { return false; } + // SELL ramps where the user broadcasts squidRouterApprove + squidRouterSwap from their own + // wallet only report tx hashes back via /v1/ramp/update.
