Networks and Contracts

Networks & Contracts

This page covers only the public, solver-facing Mainnet V6 deployment surface. Use the linked machine-readable files for current addresses, hashes, network identifiers, release identifiers, and deployment evidence.

Supported networks

Network	Chain ID	Canonical metadata
Base	8453	Network IDs
BNB Smart Chain	56	Network IDs
HyperEVM	999	Network IDs

Public solver-facing components

Component	Public integration role	Canonical source
Discovery Facade	On-chain entry point for the published discovery URI and public bindings.	On-chain fingerprint
Mainnet Registry V6	Establishes the published on-chain network, asset, route, and standards state exposed to integrations.	Public bundle
Mainnet Router V6	Canonical public execution target for a valid Nexa execution path.	Solver-facing ABI
ERC-7683 resolver	Resolves the published Permit payload to the canonical Router call through off-chain eth_call.	Standards manifest
OIF discovery module	Describes the published OIF mandate surface; it is not executable.	Standard IDs

Public relationship

The Discovery Facade provides an on-chain path to the canonical discovery URI and its published identities. The Registry and Router establish protocol identity and on-chain state. Live route terms are separately authorized by the Signed Feed, while execution requires a valid Execution Permit.

This relationship does not make the Wiki, HTTP discovery metadata, or passive indexers an execution authority.

Deterministic deployment evidence

Verify the deterministic component addresses and runtime bytecode for Base, BNB Smart Chain, and HyperEVM using:

• the root README contract table;
• the on-chain discovery fingerprint;
• the on-chain identity record; and
• the Facade deployment evidence.
