Sepolia (Chain ID: 11155111)

Ethereum’s official testnet for application developers. Core Contracts:
  • GPv2Settlement: 0x9008D19f58AAbD9eD0D60971565AA8510560ab41
  • GPv2AllowListAuthentication: 0x2c4c28DDBdAc9C5E7055b4C863b72eA0149D8aFE
  • GPv2VaultRelayer: 0xC92E8bdf79f0507f65a392b0ab4667716BFE0110

​
Contract Consistency

Notice that the core contracts share the same addresses across all networks. This deterministic deployment approach simplifies integration and reduces the complexity of multi-chain applications.
The following contracts are deployed at identical addresses across all supported networks:
  • GPv2Settlement: 0x9008D19f58AAbD9eD0D60971565AA8510560ab41
  • GPv2AllowListAuthentication: 0x2c4c28DDBdAc9C5E7055b4C863b72eA0149D8aFE
  • GPv2VaultRelayer: 0xC92E8bdf79f0507f65a392b0ab4667716BFE0110
This consistency is achieved through CREATE2 deployment, which allows for deterministic contract addresses based on the deployment bytecode and salt.

Network Information File

All deployment information is maintained in the networks.json file at the root of the repository. This file contains:
  • Contract addresses for each network
  • Deployment transaction hashes
  • Chain IDs
  • Historical deployment data

Integration

When integrating with CoW Protocol:
  1. Select the appropriate network for your use case
  2. Use the contract addresses listed above
  3. Ensure your application can handle the network’s native token (ETH, xDAI, etc.)
  4. Configure appropriate RPC endpoints for your chosen network
Always verify contract addresses through official channels before integrating. Malicious actors may attempt to impersonate official deployments.
