Contract Addresses
All smart contracts deployed for Execution Market. Many use CREATE2 for deterministic addresses across networks.
ERC-8004 Identity Contracts
| Contract | Network | Address |
|---|---|---|
| Identity Registry | All Mainnets (CREATE2) | 0x8004A169FB4a3325136EB29fA0ceB6D2e539a432 |
| Identity Registry | All Testnets (CREATE2) | 0x8004A818BFB912233c491871b3d84c89A494BD9e |
| Reputation Registry | All Mainnets (CREATE2) | 0x8004BAa17C55a88189AE136b182e5fdA19dE9b63 |
Same address on: Base, Ethereum, Polygon, Arbitrum, Avalanche, Optimism, Celo, Monad (and more) via CREATE2.
AuthCaptureEscrow Contracts
| Network | Address |
|---|---|
| Base | 0xb9488351E48b23D798f24e8174514F28B741Eb4f |
| Ethereum | 0x9D4146EF898c8E60B3e865AE254ef438E7cEd2A0 |
| Polygon | 0x32d6AC59BCe8DFB3026F10BcaDB8D00AB218f5b6 |
| Arbitrum | 0x320a3c35F131E5D2Fb36af56345726B298936037 |
| Avalanche | 0x320a3c35F131E5D2Fb36af56345726B298936037 |
| Celo | 0x320a3c35F131E5D2Fb36af56345726B298936037 |
| Monad | 0x320a3c35F131E5D2Fb36af56345726B298936037 |
| Optimism | 0x320a3c35F131E5D2Fb36af56345726B298936037 |
| Arc | 0xBdEA0D1bcC5966192B070Fdf62aB4EF5b4420cff |
The same address on Arbitrum, Avalanche, Celo, Monad, and Optimism is due to CREATE2 deterministic deployment. Arc does not share it: its escrow is x402r generation D, a separate deployment, whose operator ABI is capture/void and where a refund voids the whole capturable amount.
PaymentOperator Contracts (Fase 5 — Trustless Fee Split)
| Network | Address |
|---|---|
| Base | 0x271f9fa7f8907aCf178CCFB470076D9129D8F0Eb |
| Ethereum | 0x69B67962ffb7c5C7078ff348a87DF604dfA8001b |
| Polygon | 0xB87F1ECC85f074e50df3DD16A1F40e4e1EC4102e |
| Arbitrum | 0xC2377a9Db1de2520BD6b2756eD012f4E82F7938e |
| Avalanche | 0xC2377a9Db1de2520BD6b2756eD012f4E82F7938e |
| Celo | 0xC2377a9Db1de2520BD6b2756eD012f4E82F7938e |
| Monad | 0x9620Dbe2BB549E1d080Dc8e7982623A9e1Df8cC3 |
| Optimism | 0xC2377a9Db1de2520BD6b2756eD012f4E82F7938e |
| Arc | 0x0258472A1410Ac3Ad720f1BC83f22B3c0af1Fd9D |
Arc's operator is generation D. Arc takes payments once terraform apply puts arc in the live EM_ENABLED_NETWORKS; the signal is that GET /api/v1/h2a/payment-config lists it.
Fee Calculator
| Contract | Network | Address |
|---|---|---|
| StaticFeeCalculator (1300 BPS = 13%) | Base | 0xd643DB63028Cd1852AAFe62A0E3d2A5238d7465A |
Facilitator EOA
| Role | Address |
|---|---|
| Facilitator EOA (pays gas for all TXs) | 0x103040545AC5031A11E8C03dd11324C7333a13C7 |
Agent Identity
| Property | Value |
|---|---|
| Execution Market Agent ID | 2106 (Base Mainnet) |
| Legacy Agent ID | 469 (Sepolia — deprecated) |
