AsterPay KYA Hook — ERC-8183 Integration

Know Your Agent (KYA) verification gate for Agentic Commerce jobs.

This hook implements the IACPHook interface to enforce AsterPay's 5-layer Trust Framework before AI agents can participate in ERC-8183 commerce jobs.

How It Works

Client creates job with hook = AsterPayKYAHook

Architecture

ContractPurpose
AsterPayKYAHook.solMain hook — sanctions + trust score gate
IACPHook.solERC-8183 hook interface
IAgenticCommerce.solRead-only ACP job interface
IAgentTrustScore.solAsterPay trust score oracle interface
ISanctionsOracle.solChainalysis oracle interface

Checks Performed

  1. Sanctions screening — Chainalysis Oracle on Base (OFAC, EU, UN). Fail-closed if oracle unreachable.
  2. Trust Score — Agent must have score ≥ minTrustScore (default: 20 = verified tier)
  3. Score freshness — Score must be updated within maxScoreAge seconds (default: 3600)
  4. Tier validation — Agent must not be in "blocked" tier

const sdk = createKYAHookSDK(HOOK_ADDRESS, ACP_ADDRESS, signer);

// Pre-flight check
