## 🔄 In Progress: ChainID 138 → Mainnet Bridge Configuration

### Issue

ChainID 138 bridge contracts revert when attempting to configure Mainnet destinations via `addDestination()`. Empty revert data (`0x`) suggests either:
1. Destination already configured (most likely)
2. Contract bytecode mismatch
3. Storage/proxy pattern issue

### Resolution Strategies

**Strategy 1: Event Log Verification** (Primary)
- Check for `DestinationAdded` events to verify if already configured
- Script: `check-existing-destinations.sh`

**Strategy 2: Direct Configuration Attempt**
- Attempt `addDestination()` transaction
- Script: `configure-chain138-direct.sh`

**Strategy 3: Storage Inspection**
- Direct storage slot reading
- Verify destination state at storage level

**Strategy 4: Functional Testing**
- Test actual bridge transfer to verify functionality
- May work even if query functions fail

### Scripts Available

1. ✅ `complete-chain138-mainnet-resolution.sh` - Orchestrates all strategies
2. ✅ `diagnose-chain138-bridge-revert.sh` - Comprehensive diagnostics
3. ✅ `check-existing-destinations.sh` - Event log verification
4. ✅ `configure-chain138-direct.sh` - Direct configuration

### Documentation

- ✅ `CHAIN138_MAINNET_CCIP_RESOLUTION.md` - Detailed resolution plan
- ✅ `LINK_TOKEN_STATUS_FINAL.md` - LINK token verification
- ✅ `CCIP_RESOLUTION_SUMMARY.md` - This document

## Next Steps

1. **Execute Resolution Script** (when RPC available):
   ```bash
   ./scripts/configuration/complete-chain138-mainnet-resolution.sh
   ```

2. **Verify Configuration**:
   - Check event logs
   - Test bridge transfer functionality
   - Verify bidirectional flow

3. **Update Documentation**:
   - Mark configuration complete once verified
   - Document final resolution method

---

**Current Priority**: Event log verification to confirm if destinations are already configured
