Engineered for Security
The Vector architecture combines off-chain intelligence with hard on-chain enforcement.
1. Risk Assessment
Off-chain TEE-grade risk engine runs 5 analysis layers: allowlist, swap intent, threat intel, on-chain signals, and bytecode analysis, producing a 0-100 risk score.
2. Attestation Signing
Risk score is signed as a cryptographic attestation with a 5-minute TTL. The signature is included in the swap's hookData payload.
3. Hook Enforcement
VectorHook's beforeSwap verifies the attestation on-chain via ECDSA. PolicyEngine evaluates: ALLOW, WARN, or BLOCK. Protected pools use fail-closed enforcement.
4. Cross-Chain Monitoring
Reactive Network RSC monitors SwapBlocked events. Repeat offenders trigger cross-chain alerts via callbacks, enabling multi-chain threat propagation.
