# Bridge Configuration Guide
|
|
|
|
## Overview
|
|
|
|
After deploying CCIP WETH bridges on both Ethereum Mainnet and ChainID 138, you need to configure them to enable cross-chain transfers.
|
|
|
|
## Prerequisites
|
|
|
|
1. **Bridges deployed on both chains:**
|
|
- Mainnet: CCIPWETH9Bridge and CCIPWETH10Bridge
|
|
- ChainID 138: CCIPWETH9Bridge and CCIPWETH10Bridge
|
|
|
|
2. **Chain selectors:**
|
|
- Ethereum Mainnet: `5009297550715157269`
|
|
- ChainID 138: (to be determined from CCIP Router)
|
|
|
|
3. **Admin access** to bridge contracts
|
|
|
|
## Configuration Steps
|
|
|
|
### Step 1: Get Chain Selectors
|
|
|
|
```bash
|
|
# Get ChainID 138 selector from CCIP Router
|
|
cast call $CCIP_ROUTER "getChainSelector()" --rpc-url $RPC_URL
|
|
|
|
# Ethereum Mainnet selector is known: 5009297550715157269
|
|
```
|
|
|
|
### Step 2: Configure Mainnet Bridges
|
|
|
|
On Ethereum Mainnet, configure bridges to send to ChainID 138:
|
|
|
|
```bash
|
|
# Add ChainID 138 as destination for WETH9 bridge
|
|
cast send $MAINNET_WETH9_BRIDGE \
|
|
"addDestination(uint64,address)" \
|
|
$CHAIN138_SELECTOR \
|
|
$CHAIN138_WETH9_BRIDGE \
|
|
--rpc-url $MAINNET_RPC \
|
|
--private-key $MAINNET_PRIVATE_KEY
|
|
|
|
# Add ChainID 138 as destination for WETH10 bridge
|
|
cast send $MAINNET_WETH10_BRIDGE \
|
|
"addDestination(uint64,address)" \
|
|
$CHAIN138_SELECTOR \
|
|
$CHAIN138_WETH10_BRIDGE \
|
|
--rpc-url $MAINNET_RPC \
|
|
--private-key $MAINNET_PRIVATE_KEY
|
|
```
|
|
|
|
### Step 3: Configure ChainID 138 Bridges
|
|
|
|
On ChainID 138, configure bridges to send to Mainnet:
|
|
|
|
```bash
|
|
# Add Mainnet as destination for WETH9 bridge
|
|
cast send $CHAIN138_WETH9_BRIDGE \
|
|
"addDestination(uint64,address)" \
|
|
$MAINNET_SELECTOR \
|
|
$MAINNET_WETH9_BRIDGE \
|
|
--rpc-url $RPC_URL \
|
|
--private-key $PRIVATE_KEY
|
|
|
|
# Add Mainnet as destination for WETH10 bridge
|
|
cast send $CHAIN138_WETH10_BRIDGE \
|
|
"addDestination(uint64,address)" \
|
|
$MAINNET_SELECTOR \
|
|
$MAINNET_WETH10_BRIDGE \
|
|
--rpc-url $RPC_URL \
|
|
--private-key $PRIVATE_KEY
|
|
```
|
|
|
|
### Step 4: Verify Configuration
|
|
|
|
```bash
|
|
# Check destinations on Mainnet bridge
|
|
cast call $MAINNET_WETH9_BRIDGE \
|
|
"destinations(uint64)" \
|
|
$CHAIN138_SELECTOR \
|
|
--rpc-url $MAINNET_RPC
|
|
|
|
# Check destinations on ChainID 138 bridge
|
|
cast call $CHAIN138_WETH9_BRIDGE \
|
|
"destinations(uint64)" \
|
|
$MAINNET_SELECTOR \
|
|
--rpc-url $RPC_URL
|
|
```
|
|
|
|
## Gas Costs
|
|
|
|
Each `addDestination` call costs approximately:
|
|
- **Gas**: ~50,000 gas
|
|
- **Cost at 30 gwei**: ~0.0015 ETH (~$3.75)
|
|
- **Total for 4 calls**: ~0.006 ETH (~$15)
|
|
|
|
## Testing Cross-Chain Transfers
|
|
|
|
After configuration, test a cross-chain transfer:
|
|
|
|
```bash
|
|
# On Mainnet: Send WETH9 to ChainID 138
|
|
cast send $MAINNET_WETH9_BRIDGE \
|
|
"sendCrossChain(uint64,address,uint256)" \
|
|
$CHAIN138_SELECTOR \
|
|
$RECIPIENT_ADDRESS \
|
|
$AMOUNT \
|
|
--rpc-url $MAINNET_RPC \
|
|
--private-key $MAINNET_PRIVATE_KEY
|
|
```
|
|
|
|
## Troubleshooting
|
|
|
|
### Error: "destination not enabled"
|
|
- Ensure `addDestination` was called successfully
|
|
- Verify chain selector is correct
|
|
- Check bridge addresses are correct
|
|
|
|
### Error: "insufficient fee"
|
|
- Ensure LINK token balance is sufficient
|
|
- Check fee calculation: `calculateFee(chainSelector, amount)`
|
|
|
|
### Error: "transfer failed"
|
|
- Ensure WETH balance is sufficient
|
|
- Check WETH approval for bridge contract
