|
|
|
|

|
|
|
|
**Verification**:

|
### Expected Configuration
|
|
|
|
For bidirectional bridging between ChainID 138 ↔ Ethereum Mainnet, bridges should be configured with:
|
|
|
|
**Ethereum Mainnet → ChainID 138**:
|
|
- Destination Chain Selector: ChainID 138 selector (to be obtained from CCIP Directory)
|
|
- Receiver Bridge: `0x3304b747E565a97ec8AC220b0B6A1f6ffDB837e6` (CCIPWETH9Bridge on ChainID 138)
|
|
- Receiver Bridge: `0xe0E93247376aa097dB308B92e6Ba36bA015535D0` (CCIPWETH10Bridge on ChainID 138)
|
|
|
|
**ChainID 138 → Ethereum Mainnet**:
|
|
- Destination Chain Selector: `5009297550715157269` (Ethereum Mainnet CCIP selector)
|
|
- Receiver Bridge: `0x3304b747E565a97ec8AC220b0B6A1f6ffDB837e6` (CCIPWETH9Bridge on Mainnet)
|
|
- Receiver Bridge: `0xe0E93247376aa097dB308B92e6Ba36bA015535D0` (CCIPWETH10Bridge on Mainnet)
|
|
|
|
### ChainID 138 Bridge Verification
|
|
|
|
**ChainID 138 RPC**: `http://192.168.11.211:8545`
|
|
|
|
**CCIPWETH9Bridge (ChainID 138)**: `0x3304b747E565a97ec8AC220b0B6A1f6ffDB837e6`
|
|
- Status: ✅ Deployed (verified in Task 1)
|
|
- Destination chains: Not checked (function calls reverted - proxy pattern)
|
|
|

|
### Action Required
|
|
|
|
**Configuration Needed**:
|
|
|
|
1. **Configure Mainnet Bridges** to accept ChainID 138 as destination:
|
|
- Add ChainID 138 chain selector to destination chains
|
|
- Set receiver bridge addresses on ChainID 138
|
|
|
|
2. **Configure ChainID 138 Bridges** to accept Mainnet as destination:
|
|
- Add Mainnet chain selector (`5009297550715157269`) to destination chains
|
|
- Set receiver bridge addresses on Mainnet
|
|
|
|
3. **Obtain ChainID 138 CCIP Selector**:
|
|
- Query Chainlink CCIP Directory for ChainID 138
|
|
- Use official selector for configuration
|
|
|
|
### Configuration Commands
|
|
|
|
**To configure a destination chain on a bridge**:
|
|
|
|
```bash
|
|
# On Mainnet bridge, add ChainID 138 destination
|
|
cast send 0x3304b747E565a97ec8AC220b0B6A1f6ffDB837e6 \
|
|
"addDestination(uint64,address)" \
|
|
<CHAINID_138_SELECTOR> \
|
|
0x3304b747E565a97ec8AC220b0B6A1f6ffDB837e6 \
|
|
--rpc-url https://eth.llamarpc.com \
|
|
--private-key $PRIVATE_KEY
|
|
```
|
|
|
|
**Note**: Requires admin access (`onlyAdmin` modifier).
|
|
|
|
## Conclusion
|
|
|
|
✅ **Verification Complete**
|
|
|
|
**Findings**:
|
|
- Mainnet bridges are deployed but not configured with destination chains
|
|
- ChainID 138 bridges are deployed but configuration status unknown (proxy pattern)
|
|
- Bridges require configuration to enable cross-chain transfers
|
|
|
|
**Recommendation**: Configure destination chains on all bridges before enabling cross-chain transfers.
