Crate cow_chains 

cow-chains — Layer 0 chain configuration for the CoW Protocol SDK.

Centralises all deployment-specific knowledge: which chains are supported, where the protocol contracts live, what the native/wrapped tokens are, and how to reach the orderbook API.

This crate sits at Layer 0 of the workspace DAG and has no dependencies on any other internal crate.

Submodules

Module	Purpose
chain	SupportedChainId, Env, API base URLs, explorer links
chains	Extended chain enums (EvmChains, NonEvmChains), rich ChainInfo metadata, classification helpers
contracts	Protocol contract addresses (SETTLEMENT_CONTRACT, VAULT_RELAYER, …), CREATE2 helpers, EIP-1967 proxy slots
tokens	Native/wrapped currency constants and per-chain TokenInfo
params	CowSwapConfig executor configuration and TokenRegistry
