---

## Phase 4: Verification

### Contract Verification
- [ ] Verify CCIPRouter on explorer
- [ ] Verify CCIPWETH9Bridge on explorer

### Configuration Verification
- [ ] Run verification script: `./scripts/deployment/verify-ccip-deployment.sh`
- [ ] Verify router supports Ethereum Mainnet
- [ ] Verify bridges have destinations configured
- [ ] Verify chain selector is correct

### Functional Testing
- [ ] Test router message sending
