v0.5.0
8beb59f

The first real customer-facing x402 settlement went through the self-serve proxy flow on 2026-05-31. A live third-party API (CoinGecko BTC/ETH price feed) is now wrapped behind suverse-pay's /v1/proxy/... endpoint, paid per call in USDC on Base mainnet, with on-chain settlement verified end-to-end.

This release marks the transition from "wired up against documented spec" to "settling real money for real callers."

Milestone — first customer settle

  • 7 successful on-chain settlements on Base mainnet through the CoinGecko proxy.
  • First settled tx hash: 0xded439c578f10c3b606264e7eec2ff691684d2c0a939b3d02cc86e0826394009 — block 46709549.
  • End-to-end demonstrated using the published @suverselabs/x402-client@0.1.0 buyer SDK, not a workspace-symlinked dev build.
  • Settled via the coinbase-cdp adapter; CDP facilitator integration verified.
  • Payer balance moved $2.7465 → $2.6765 (−$0.07 over 7 settles), platform fee 30 bps withheld per row.
  • Live endpoint: https://proxy.suverse.io/v1/proxy/reskey_1166628d/prices

What shipped since v0.4.0

Self-serve proxy flow (the headline path)

  • feat(proxy) — wrap any HTTPS API behind a paid endpoint, the core proxy app.
  • fix(proxy) — header hygiene on upstream call + downstream response. Strips x-forwarded-* / x-real-ip / nginx infra headers on the upstream call (Cloudflare-fronted APIs like CoinGecko 403'd otherwise) and strips content-encoding + content-length from upstream responses (undici was double-gunzipping and aborting the socket).
  • fix(coinbase-cdp) — persist EIP-712 domain extras for EVM USDC capabilities. CDP's /supported often omits extra for EVM kinds; static EVM_USDC_EIP712_DOMAINS floor now backs the adapter so 402 challenges always carry the EIP-712 domain.
  • feat(proxy) — upstream health-probe pipeline (HC1–HC8): probe before 402 challenge, return 503 upstream_unavailable on failure, HEALTH_CHECK_TIMEOUT_MS env override, full test coverage.
  • fix(proxy) — per-VM scheme in 402 challenges so Cosmos challenges accept on the buyer side.

Buyer SDK + MCP

  • feat(packages) — @suverselabs/x402-client@0.1.0 published. Unified fetch-shaped buyer SDK covering 21 EVM chains, Solana, Cosmos Noble, and TRON gasfree (TIP-712 PermitTransfer). 165 tests; Cosmos + Solana mainnet settles proven on the wire-format probe.
  • feat(mcp) — @suverselabs/x402-mcp@0.0.1 published. stdio MCP server for Claude Desktop / Cursor with catalog_search, catalog_compare, buy_and_call, list_recent_purchases.

Dashboard, catalog, buyer-mode

  • feat(dashboard) — buyer-mode foundation (Seller/Buyer mode toggle, separate landing shell), agent API keys (sup_agent_<32>), per-chain wallet registration with on-chain validation, spending-limits accounting model, paginated payments table + CSV export, spend overview cards.
  • feat(catalog) — auto-create listing on proxy creation, slug-based detail routes with How-to-use code snippets, admin moderation queue gated by ADMIN_EMAILS, sitemap.xml + robots.txt + /.well-known/x402 for ecosystem crawlers.
  • feat(mobile) — PWA manifest + icons, hamburger drawer + responsive header, bottom-nav tab bar in PWA standalone mode, responsive Settles table, iOS safe-area + tap polish (Tasks M1–M5).
  • feat(dashboard) — welcome tour + 3-step onboarding tracker, OAuth profile capture, in-app Help page, inline tooltips on high-value form fields, success banner on proxy detail, empty-state CTAs.

Protocol surface

  • feat(adapter-mpp) — Tempo Moderato direct-RPC verify+settle, MPP POST /mpp/charge route, payments.protocol + mpp_method/intent columns. Stripe's Machine Payments Protocol now alongside x402 in the same gateway.
  • feat(signer) — SKALE Base mainnet + Sepolia chain entries (Bridged USDC v2, EIP-3009 typehash verified on-chain), routing config + facilitator wiring for SKALE Base via PayAI. Mainnet smoke still pending.

Stability

  • fix(mobile) — drawer panel createPortal out of backdrop-blur containing block; stop dragging pg into client bundle via the async header.
  • fix(dashboard) — qualify proxy SELECT columns to avoid 42702 in JOIN; admin bypass for key + probe rate limits.
