Contract Addresses

Comprehensive reference of all CoW Protocol smart contract addresses across supported networks

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.

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
