Supported Networks

Deployed contract addresses across all supported blockchain networks

Contract Addresses

All contracts are deployed deterministically with CREATE2 and share the same addresses across supported networks:

Contract	Address
FlashLoanRouter	0x9da8B48441583a2b93e2eF8213aAD0EC0b392C69
AaveBorrower	0x7d9C4DeE56933151Bc5C909cfe09DEf0d315CB4A
ERC3156Borrower	0x47d71b4B3336AB2729436186C216955F3C27cD04

These addresses are identical across all supported networks due to CREATE2 deterministic deployment.

See CIP 66 for details.

Network Summary

The Flash Loan Router is deployed on 12 networks:

• Mainnet: Ethereum, Gnosis Chain
• Testnet: Sepolia
• Layer 2: Arbitrum One, Optimism, Base, Linea
• Sidechains: Polygon, BNB Smart Chain, Avalanche C-Chain, MODE, RSK Mainnet

Adding New Networks

To deploy contracts on a new network, follow the Deployment Guide. The CREATE2 deployment ensures contracts will have the same addresses as existing networks.

Requirements for New Networks

1. Network compatibility

   The network must be EVM-compatible and support:

   • Solidity 0.8.28
   • Cancun EVM version
   • CREATE2 opcode
2. CoW Protocol deployment

   CoW Protocol Settlement contract must be deployed at: 0x9008D19f58AAbD9eD0D60971565AA8510560ab41

3. Flash loan providers

   At least one supported flash loan provider should be available:

   • Aave (for AaveBorrower)
   • ERC-3156 compliant lenders like Maker (for ERC3156Borrower)

Verifying Deployments

To verify a contract deployment on any network:

1. Check the contract address matches the expected deterministic address
2. View the deployment transaction on the network’s block explorer
3. Verify the contract source code (see Contract Verification)
4. Confirm the constructor arguments match expected values

All deployment information is tracked in the networks.json file in the repository root.
