## Contract Addresses

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

* `FlashLoanRouter`: <InlineResource value="0x9da8B48441583a2b93e2eF8213aAD0EC0b392C69" chain="ethereum" showExplorer />
* `AaveBorrower`: <InlineResource value="0x7d9C4DeE56933151Bc5C909cfe09DEf0d315CB4A" chain="ethereum" showExplorer />
* `ERC3156Borrower`: <InlineResource value="0x47d71b4B3336AB2729436186C216955F3C27cD04" chain="ethereum" showExplorer />

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

## 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](/flash-loan-router/operations/deployment-guide). The CREATE2 deployment ensures contracts will have the same addresses as existing networks.

### Requirements for New Networks

<Steps>
  <Step title="Network compatibility">
    The network must be EVM-compatible and support:

    * Solidity 0.8.28
    * Cancun EVM version
    * CREATE2 opcode
  </Step>

  <Step title="CoW Protocol deployment">
    CoW Protocol Settlement contract must be deployed at:
    `0x9008D19f58AAbD9eD0D60971565AA8510560ab41`
  </Step>

  <Step title="Flash loan providers">
    At least one supported flash loan provider should be available:

    * Aave (for AaveBorrower)
    * ERC-3156 compliant lenders like Maker (for ERC3156Borrower)
  </Step>
</Steps>

## 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](/flash-loan-router/operations/verification))
4. Confirm the constructor arguments match expected values

<Tip>
  All deployment information is tracked in the `networks.json` file in the repository root.
