Use this page when you need to inspect deployed onchain execution contracts directly, verify source code, or confirm a factory address used for low-level signing. The AgreementFactory address is the verifyingContract for deploy permit signatures. Each deployed agreement is an AgreementEngine clone created by the factory. Input permit signatures use the deployed agreement address as the verifyingContract. The TypeScript SDK resolves factory addresses from its protocol deployment registry for the selected chainId. The table below mirrors the current registry deployments.

Contract roles

ContractRole
AgreementFactoryDeploys new agreement instances and verifies deploy permit signatures. Use this address as the factory address for direct deploy signing.
AgreementEngine implementationShared implementation for agreement clone instances. Each deployed agreement clone stores its own document hash, state, inputs, transitions, verifier registrations, initialization values, and optional actions.
For low-level typed data, see EIP-712 Signing Reference. For the execution model, see Onchain execution engine.
