Contract Addresses

All CoW Protocol smart contract addresses deployed across supported networks.

Core Contracts

All core contracts are deployed at identical addresses across all supported networks using CREATE2 deterministic deployment.

GPv2Settlement:
GPv2VaultRelayer:
GPv2AllowListAuthentication (Proxy):

The GPv2AllowListAuthentication implementation is at 0x9E7Ae8Bdba9AA346739792d219a808884996Db67.

Supported Networks

CoW Protocol is deployed on the following networks:

Network	Chain ID	Type
Ethereum	1	Mainnet
Gnosis Chain	100	Mainnet
Arbitrum One	42161	Layer 2
Base	8453	Layer 2
Polygon	137	Sidechain
Avalanche C-Chain	43114	Sidechain
BNB Smart Chain	56	Sidechain
Optimism	10	Layer 2
Linea	59144	Layer 2
Plasma	9745	Layer 2
Ink	57073	Layer 2
Sepolia	11155111	Testnet

Deprecated Networks

Network	Status

Goerli	Deprecated - not recommended for new integrations

Integration Example

import { domain } from "@cowprotocol/contracts";

// Ethereum Mainnet
const mainnetDomain = domain(1, "0x9008D19f58AAbD9eD0D60971565AA8510560ab41");

// Gnosis Chain
const gnosisDomain = domain(100, "0x9008D19f58AAbD9eD0D60971565AA8510560ab41");

// Arbitrum One
const arbitrumDomain = domain(42161, "0x9008D19f58AAbD9eD0D60971565AA8510560ab41");

Best Practices

Store addresses in configuration files rather than hardcoding them
Use environment variables for different networks
Validate addresses before executing transactions
Always verify contract addresses through official channels before integrating
