## ⚠️ Technical Limitation: Chain 138 Selector

### Issue

The Chain 138 selector (`866240039685049171407962509760789466724431933144813155647626`) exceeds the maximum value for `uint64` (18,446,744,073,709,551,615), preventing direct configuration via `cast send`.

### Impact

- **Chain 138 → Ethereum Mainnet**: ✅ Fully functional (configured from Chain 138 side)
- **Ethereum Mainnet → Chain 138**: ⚠️ Cannot be configured via standard `cast send` command

### Workaround

The Chain 138 bridges are fully configured to receive from Ethereum Mainnet. For Ethereum Mainnet → Chain 138 transfers, the configuration would need to be done via:
1. Direct contract interaction (not via cast)
2. Custom script using lower-level ABI encoding
3. Manual transaction construction

**Note**: This limitation does not affect the functionality of the bridges for all other routes (6/7 destinations on Ethereum Mainnet are fully functional).
