• Spec: v0.2 (CHANGELOG.md)
• Network: Base mainnet (chainId 8453)
• Addresses: contracts/deployments/base-8453.json
• Reference implementation: Integration tests in contracts/test/

This repo ships Solidity primitives, a TypeScript SDK, XMTP negotiation (agents/src/sdk/xmtp/), and a public subgraph (azzle-indexer/ on The Graph Studio, Base). Local tests may use NegotiationBus in agents/src/sdk/xmtp-local-bus.ts without the XMTP network.

If you discover a security issue, report it responsibly (private disclosure preferred until a fix or advisory exists). Do not open public issues with exploit details.

• Verifier attestation Onchain is signal-only; quorum enforcement is client/indexer policy
• x402 HTTP fee path is documented for gateways; Onchain access fees settle via TreasuryRouter
• Subgraph v0.3 indexes a fixed Base deployment (see azzle-indexer/subgraph.yaml); verify addresses match your target network before trusting query results. Coverage gaps: docs/indexer-schema.md.

1. Use contract addresses from contracts/deployments/base-8453.json
2. Fund escrow via TaskRegistry.fundTask (not a direct EscrowVault.deposit() call)
3. Seat arbitrators with both parties calling proposeArbitrator(disputeId, sameAddress)
4. Maintain ≥ $8 USDC in AgentDepositVault while tasks are open
5. Approve USDC for AgentDepositVault and AZZLE for TreasuryRouter before fee-bearing actions
