## Critical Issues Blocking Bridging
|
|
|
|
### 🔴 **Issue 1: App-Level Destination Routing Table Not Configured**
|
|
|
|
**Problem**:
|
|
- Bridge contracts maintain their own `destinations[selector]` mapping
|
|
- Ethereum Mainnet destination (selector: 5009297550715157269) is **NOT configured**
|
|
- Configuration transaction stuck in mempool (nonce 36/37)
|
|
|
|
**Impact**:
|
|
- **CRITICAL** - Cannot bridge to Ethereum Mainnet
|
|
- Error: `CCIPWETH9Bridge: destination not enabled`
|
|
|
|
**Status**: ❌ **BLOCKING**
|
|
|
|
**Resolution Required**:
|
|
1. Clear stuck transaction from mempool, OR
|
|
2. Wait for transaction to timeout/expire, OR
|
|
3. Use different account to configure destination
|
|
|
|

|
|
|
|
### 🟡 **Issue 2: CCIP Fee Calculation Failing**
|
|
|
|
**Problem**:
|
|
- Scripts cannot calculate CCIP fees
|
|
- `calculateFee()` calls fail or return 0
|
|
- May require LINK tokens for fee payment
|
|
|
|
**Impact**:
|
|
- **WARNING** - Cannot estimate total bridge cost
|
|
- May fail at execution if fees not available
|
|
|
|
**Status**: ⚠️ **NON-BLOCKING** (but concerning)
|
|
|
|
**Resolution Required**:
|
|
1. Verify LINK token balance
|
|
2. Check FeeQuoter contract accessibility
|
|
3. Verify fee payment mechanism
|
|
|
|

|
|
|
|
### 🟡 **Issue 3: CCIP Lane Configuration Not Verifiable**
|
|
|
|
**Problem**:
|
|
- Cannot verify Router → OnRamp mappings
|
|
- Cannot verify OnRamp destination allowlists
|
|
- Cannot verify OffRamp source allowlists (from source chain)
|
|
|
|
**Impact**:
|
|
- **WARNING** - Unknown if CCIP lanes are properly configured
|
|
- May fail at CCIP level even if app-level routing is fixed
|
|
|
|
**Status**: ⚠️ **POTENTIALLY BLOCKING**
|
|
|
|
**Resolution Required**:
|
|
1. Contract verification on Blockscout
|
|
2. Admin access to verify Router/OnRamp/OffRamp configs
|
|
3. Test with small amount once destination routing is fixed

## Recommendations
|
|
|
|
### Immediate Actions (Critical)
|
|
|
|
1. **Resolve Stuck Transaction**:
|
|
- Clear mempool for address 0x4A666F96fC8764181194447A7dFdb7d471b301C8
|
|
- OR wait for transaction timeout
|
|
- OR use different account to configure destination
|
|
|
|
2. **Configure Ethereum Mainnet Destination**:
|
|
```bash
|
|
./scripts/fix-bridge-errors.sh [private_key] 0x2a0840e5117683b11682ac46f5cf5621e67269e3
|
|
```
|
|
|
|
3. **Verify Configuration**:
|
|
```bash
|
|
./scripts/check-bridge-config.sh
|
|
```
|
|
|
|
### Short-Term Actions (Important)
|
|
|
|
4. **Verify CCIP Lane Configuration**:
|
|
- Contract verification on Blockscout
|
|
- Query Router/OnRamp/OffRamp configs
|
|
- Verify destination allowlists
|
|
|
|
5. **Verify Token Pool Configuration**:
|
|
- Query TokenAdminRegistry
|
|
- Verify token → pool mappings
|
|
- Check pool permissions
|
|
|
|
6. **Test Fee Calculation**:
|
|
- Verify LINK token balance
|
|
- Test FeeQuoter accessibility
|
|
- Document fee payment mechanism
|
|
|
|
### Long-Term Actions (Nice to Have)
|
|
|
|
7. **Comprehensive Verification Script**:
|
|
- Check all CCIP components
|
|
- Verify all destination chains
|
|
- Generate complete status report
|
|
|
|
8. **Monitoring Setup**:
|
|
- Monitor CCIP message lifecycle
|
|
- Track bridge transaction success rates
|
|
- Alert on configuration changes
|
|
|

|

|
|
## Conclusion
|
|
|
|
**Current State**: The CCIP infrastructure is **deployed and partially configured**, but **critical app-level routing is incomplete** due to a stuck transaction. Once the destination routing table is configured, the system should be functional, but **CCIP lane configuration and token pool mappings need verification** to ensure end-to-end functionality.
|
|
|
|
**Blocking Issue**: App-level destination routing table (your bridge's `destinations[selector]` mapping) is the immediate blocker. CCIP's internal routing (Router/OnRamp/OffRamp) may be configured, but cannot be verified from the source chain.
|
|
|
|
**Next Steps**:
|
|
1. Resolve stuck transaction
|
|
2. Configure Ethereum Mainnet destination
|
|
3. Test with small amount (0.001 ETH)
|
|
4. Verify CCIP lane configuration
|
|
5. Verify token pool configuration
|
