Sentinel is an ERC-8004-compliant autonomous trading agent optimized for Best Validation & Trust Model and Best Compliance & Risk Guardrails. Architecture: - Canonical identity: Shared Sepolia AgentRegistry (ERC-8004 standard) - Decision signing: Every trade, exit, veto, halt, heartbeat is EIP-712 signed - Checkpoint chain: Local tamper-evident hash chain with replay capability - On-chain anchoring: Actionable artifacts posted to ValidationRegistry for third-party verification - Trust model: Deterministic formula (identity age, registration, checkpoint integrity, provenance, attestation, risk health, consistency) gates trade execution size in real-time Verification Paths: 1. Browser: Open checkpoint → inspect EIP-712 payload → verify signature locally using ethers.js 2. CLI: npm run verify-checkpoints validates hash chain, signatures, and on-chain attestations 3. On-chain: Query Sepolia ValidationRegistry to reconcile local artifacts Compliance: - Trade vetoes: Signed with specific guardrail breach reason - Scheduled halts: Kill-switch as auditable artifact, not silent failure - Heartbeat anchors: Hourly on-chain proofs of constraint adherence - Risk monitor: Drawdown, daily P&L, position limits, trust gate all live and visible
