## ⚠️ Important Notes

### Predeployed Contracts (No Deployment Needed)
- **WETH9**: `0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2` (canonical Mainnet address)
- **WETH10**: `0xf4BB2e28688e89fCcE3c0580D37d36A7672E8A9f` (canonical Mainnet address)

### CCIPRouter Requirement
- Bridge contracts require CCIPRouter to be deployed/configured
- Using Chainlink's official router: `0x80226fc0Ee2b096224EeAc085Bb9a8cba1146f7D`
- Verify router is accessible before deploying bridges

## 📝 Next Steps

1. **Compile Contracts**:
   ```bash
   ./scripts/deployment/compile-test-mainnet-contracts.sh
   ```

2. **Check Gas Prices**:
   ```bash
   ./scripts/deployment/get-mainnet-gas-prices.sh
   ```

3. **Calculate Costs**:
   ```bash
   ./scripts/deployment/calculate-accurate-deployment-costs.sh
   ```

4. **Deploy in Priority Order**:
   ```bash
   # 1. Deploy CCIPLogger
   npx hardhat run scripts/ccip-deployment/deploy-ccip-logger.js --network mainnet
   
   # 2. Deploy CCIPWETH9Bridge (after CCIPRouter configured)
   forge script script/DeployCCIPWETH9Bridge.s.sol --rpc-url $ETHEREUM_MAINNET_RPC --broadcast --private-key $PRIVATE_KEY
   
   # 3. Deploy CCIPWETH10Bridge (after CCIPRouter configured)
   forge script script/DeployCCIPWETH10Bridge.s.sol --rpc-url $ETHEREUM_MAINNET_RPC --broadcast --private-key $PRIVATE_KEY
   ```
