# Bidirectional Bridge Configuration Guide
|
|
|
|
**Date**: 2025-01-18
|
|
**Purpose**: Complete guide for configuring full bidirectional bridge between ChainID 138 and Ethereum Mainnet
|
|
|
|
## Overview
|
|
|
|
This guide provides step-by-step instructions for configuring both directions of the cross-chain bridge:
|
|
- ChainID 138 → Ethereum Mainnet
|
|
- Ethereum Mainnet → ChainID 138
|
|
|
|
---
|
|
|
|
## Prerequisites
|
|
|
|
### Required
|
|
|
|
1. **Admin Private Key**: Must have access to bridge admin accounts
|
|
2. **RPC Access**:
|
|
- Mainnet RPC: `https://eth.llamarpc.com` or similar
|
|
- ChainID 138 RPC: `http://192.168.11.211:8545` (VMID 2101)
|
|
3. **Chain Selectors**:
|
|
- Mainnet: `5009297550715157269` ✅ (Known)
|
|
- ChainID 138: See selector determination below
|
|
|
|
---
|
|
|
|
## Step 1: Determine ChainID 138 Selector
|
|
|
|
### Option A: Use networks.json Value
|
|
|
|
**From `networks.json`**:
|
|
```json
|
|
"chainSelector": "5009297550715157269"
|
|
```
|
|
|
|
**Note**: This is the same as Mainnet. Verify if correct for your CCIP implementation.
|
|
|
|
**To use**:
|
|
```bash
|
|
export CHAIN138_SELECTOR="5009297550715157269"
|
|
# Or add to .env:
|
|
echo "CHAIN138_SELECTOR=5009297550715157269" >> .env
|
|
```
|
|
|
|
### Option B: Use Chain ID Directly (Custom CCIP)
|
|
|
|
**For custom CCIP implementations**, the selector may be the chain ID:
|
|
```bash
|
|
export CHAIN138_SELECTOR="138"
|
|
# Or add to .env:
|
|
echo "CHAIN138_SELECTOR=138" >> .env
|
|
```
|
|
|
|
### Option C: Official Chainlink CCIP Selector
|
|
|
|
If using official Chainlink CCIP:
|
|
1. Query Chainlink CCIP Directory
|
|
2. Contact Chainlink for ChainID 138 registration
|
|
3. Use official selector provided
|
|
|
|
### Helper Script
|
|
|
|
Run the helper script to check sources:
|
|
```bash
|
|
./scripts/configuration/find-chain-selector.sh
|
|
```
|
|
|
|
---
|
|
|
|
## Step 2: Configure ChainID 138 → Mainnet (Direction 1)
|
|
|
|
**Status**: ✅ **Ready to execute** (doesn't require ChainID 138 selector)
|
|
|
|
```bash
|
|
./scripts/configuration/configure-chain138-to-mainnet.sh
|
|
```
|
|
|
|
**What it does**:
|
|
- Configures WETH9 Bridge on ChainID 138 to send to Mainnet
|
|
- Configures WETH10 Bridge on ChainID 138 to send to Mainnet
|
|
- Uses Mainnet selector (`5009297550715157269`) which is known
|
|
|
|
**Expected Output**:
|
|
```
|
|
✓ WETH9 Bridge configured (ChainID 138 → Mainnet)
|
|
✓ WETH10 Bridge configured (ChainID 138 → Mainnet)
|
|
```
|
|
|
|
---
|
|
|
|
## Step 3: Configure Mainnet → ChainID 138 (Direction 2)
|
|
|
|
**Status**: ⚠️ **Requires ChainID 138 selector**
|
|
|
|
```bash
|
|
# Ensure CHAIN138_SELECTOR is set in .env or environment
|
|
./scripts/configuration/configure-mainnet-to-chain138.sh
|
|
```
|
|
|
|
**What it does**:
|
|
- Configures WETH9 Bridge on Mainnet to send to ChainID 138
|
|
- Configures WETH10 Bridge on Mainnet to send to ChainID 138
|
|
- Uses ChainID 138 selector (from environment)
|
|
|
|
**Expected Output**:
|
|
```
|
|
✓ WETH9 Bridge configured (Mainnet → ChainID 138)
|
|
✓ WETH10 Bridge configured (Mainnet → ChainID 138)
|
|
```
|
|
|
|
---
|
|
|
|
## Step 4: Full Bidirectional Configuration (Alternative)
|
|
|
|
**Use the full configuration script** (if selector is set):
|
|
|
|
```bash
|
|
# Ensure CHAIN138_SELECTOR is in .env
|
|
./scripts/configuration/configure-bridge-destinations.sh
|
|
```
|
|
|
|
This script configures both directions in one run.
|
|
|
|
---
|
|
|
|
## Step 5: Verify Configuration
|
|
|
|
**Verify all bridge configurations**:
|
|
|
|
```bash
|
|
./scripts/configuration/verify-bridge-configuration.sh
|
|
```
|
|
|
|
**Expected Output**:
|
|
- Mainnet bridges should show ChainID 138 selector in destinations
|
|
- ChainID 138 bridges should show Mainnet selector in destinations
|
|
|

|
### Bridge Addresses
|
|
|
|
| Bridge | Mainnet Address | ChainID 138 Address |
|
|
|--------|----------------|---------------------|
|
|
| CCIPWETH9Bridge | `0x3304b747E565a97ec8AC220b0B6A1f6ffDB837e6` | `0x3304b747E565a97ec8AC220b0B6A1f6ffDB837e6` |
|
|
| CCIPWETH10Bridge | `0x8078A09637e47Fa5Ed34F626046Ea2094a5CDE5e` | `0x8078A09637e47Fa5Ed34F626046Ea2094a5CDE5e` |
|
|
|
|
### Chain Selectors
|
|
|
|
| Chain | Selector | Status |
|
|
|-------|----------|--------|
|
|
| Ethereum Mainnet | `5009297550715157269` | ✅ Known |
|
|
| ChainID 138 | See Step 1 | ⚠️ To be determined |
|
|
|
|
### Destination Configuration
|
|
|
|
**ChainID 138 Bridges → Mainnet**:
|
|
- Destination Selector: `5009297550715157269`
|
|
- Receiver WETH9 Bridge: `0x3304b747E565a97ec8AC220b0B6A1f6ffDB837e6`
|
|
- Receiver WETH10 Bridge: `0x8078A09637e47Fa5Ed34F626046Ea2094a5CDE5e`
|
|
|
|
**Mainnet Bridges → ChainID 138**:
|
|
- Destination Selector: `<CHAIN138_SELECTOR>` (from Step 1)
|
|
- Receiver WETH9 Bridge: `0x3304b747E565a97ec8AC220b0B6A1f6ffDB837e6`
|
|
- Receiver WETH10 Bridge: `0x8078A09637e47Fa5Ed34F626046Ea2094a5CDE5e`
|
|
|
|

|
|
|
|
## Troubleshooting
|
|
|
|
### Configuration Fails
|
|
|
|
**Check**:
|
|
- `PRIVATE_KEY` is set and correct
|
|
- Private key has admin access to bridges
|
|
- RPC endpoints are accessible
|
|
- ChainID 138 selector is correct
|
|
|
|
**Error: "destination already exists"**:
|
|
- Destination may already be configured
|
|
- Verify with `verify-bridge-configuration.sh`
|
|
|
|
**Error: "only admin"**:
|
|
- Private key doesn't have admin access
|
|
- Verify admin address: `cast call <BRIDGE> "admin()" --rpc-url <RPC>`
|
|
|
|
### Selector Issues
|
|
|
|
**If selector is incorrect**:
|
|
1. Bridges can be reconfigured with correct selector
|
|
2. Use `removeDestination()` to remove incorrect entry
|
|
3. Use `addDestination()` with correct selector
|
|
|
|
**To check current destinations**:
|
|
```bash
|
|
cast call <BRIDGE_ADDRESS> "getDestinationChains()(uint64[])" --rpc-url <RPC>
|
|
```
|
|
|
|

|
|
|
|
## Testing After Configuration
|
|
|
|
### Test ChainID 138 → Mainnet
|
|
|
|
1. Approve WETH9 on ChainID 138 for bridge
|
|
2. Send small amount via bridge
|
|
3. Verify receipt on Mainnet
|
|
|
|
### Test Mainnet → ChainID 138
|
|
|
|
1. Approve WETH9 on Mainnet for bridge
|
|
2. Send small amount via bridge
|
|
3. Verify receipt on ChainID 138
|
|
|

|
|
|
|
## Quick Start (If Selector Known)
|
|
|
|
```bash
|
|
# 1. Set selector in .env
|
|
echo "CHAIN138_SELECTOR=5009297550715157269" >> .env # Or appropriate value
|
|
|
|
# 2. Configure ChainID 138 → Mainnet
|
|
./scripts/configuration/configure-chain138-to-mainnet.sh
|
|
|
|
# 3. Configure Mainnet → ChainID 138
|
|
./scripts/configuration/configure-mainnet-to-chain138.sh
|
|
|
|
# 4. Verify
|
|
./scripts/configuration/verify-bridge-configuration.sh
|
|
```
|
|

|
## Status
|
|
|
|
✅ **Configuration scripts ready**
|
|
- ChainID 138 → Mainnet: Ready to execute
|
|
- Mainnet → ChainID 138: Ready to execute (requires selector)
|
|
|
|
⚠️ **Selector determination needed**
|
|
- See Step 1 for selector options
|
|
- Use helper script: `find-chain-selector.sh`
|
|
|

|
|
|
|
**Next Steps**: Determine ChainID 138 selector and run configuration scripts for full bidirectional setup.
