Syntx — Shielded Cross-Venue Perp Execution on Solana

Built for the Solana Frontier Hackathon (Apr 6 – May 11, 2026)

Your perp trade is encrypted. The solver routes it across Jupiter Perps, Percolator, and Drift for best execution. No one sees your order until it fills.

The same VenueAdapter infrastructure powers structured product vaults — a principal-protected SOL vault (delta hedge + Kamino lending) and a funding rate harvest vault.

What Syntx Does

1. Shielded Perp Intents

Submit an encrypted trading intent. The solver decrypts, scores venues, splits the order, and fills at the best blended price. NaCl box encryption (Curve25519-XSalsa20-Poly1305). On-chain privacy matcher. Real TradeCpi execution.

2. Structured Product Vaults

• Principal Protected SOL — Kamino lending (yield for protection) + delta-hedged Jupiter Perps position (Black-Scholes option replication). After 30 days, you get back at least your deposit.
• SOL Funding Rate — Collects perpetual funding rate payments across any venue.

3. Composable Vault Layer

VenueAdapter interface — implement 6 methods to add any DEX. The strategy and routing code stays unchanged. Five adapters: Percolator, Jupiter Perps, Phoenix, Kamino, VenueRouter.

Architecture

User Intent (encrypted)
  → Solver (decrypt + validate)
    → IntentRouter (score venues + split order)
      → VenueAdapter (execute on each venue)
        ├── Percolator (slab-based risk engine)
        ├── Jupiter Perps (oracle-based AMM)
        ├── Phoenix (CLOB orderbook)
        ├── Kamino (USDC lending)
        └── + any new venue

Structured Product Vault
  → Keeper (strategy loop)
    ├── KaminoAdapter → deposit USDC (lending yield)
    └── JupiterPerpsAdapter → delta hedge (Black-Scholes)

Running Locally

# 1. Start local validator with all programs
solana-test-validator \
  --bpf-program AHS7CyMJwSbt6P2oRJxxuG3f2rKETbJjgsiWXCchpkrL percolator-prog/target/deploy/percolator_prog.so \

  --reset

# 2. Setup intent pipeline (creates slab, LP, user, matcher, oracle)
cd keeper && SOLANA_RPC_URL=http://localhost:8899 npx ts-node src/setup-intent.ts

# 3. Start frontend
cd app && npm run dev

# 4. Open http://localhost:3000/vaults/trade and submit an intent

Why This Exists

Cross-venue spot routing exists (Jupiter, 1inch). Cross-venue perp routing with privacy does not exist anywhere.

We run funding rate vaults on Drift (Yogi, mainnet) and Hyperliquid (Kodiak, mainnet). When Drift was exploited, single-venue vaults lost everything overnight. Syntx is the architecture we wished existed.
