|
||||
|
||||
### Step 1: Check Network Health
|
||||
```bash
|
||||
# Check current block
|
||||
cast block-number --rpc-url http://192.168.11.211:8545
|
||||
|
||||
# Check if blocks are recent (should be within last 10 seconds)
|
||||
cast block latest --rpc-url http://192.168.11.211:8545 | grep timestamp
|
||||
```
|
||||
|
||||
### Step 2: Wrap ETH to WETH9
|
||||
```bash
|
||||
AMOUNT_WEI="1000000000000000" # 0.001 ETH
|
||||
PRIVATE_KEY="your_private_key_here"
|
||||
|
||||
cast send 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2 \
|
||||
"deposit()" \
|
||||
--value $AMOUNT_WEI \
|
||||
--private-key $PRIVATE_KEY \
|
||||
--rpc-url http://192.168.11.211:8545 \
|
||||
--gas-price 1000000
|
||||
```
|
||||
|
||||
### Step 3: Approve WETH9 (One-time)
|
||||
```bash
|
||||
BRIDGE="0xBd5F698E6490A6126E0F3DF6Ce4E83856092e239"
|
||||
MAX_UINT256="115792089237316195423570985008687907853269984665640564039457584007913129639935"
|
||||
|
||||
cast send 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2 \
|
||||
"approve(address,uint256)" \
|
||||
$BRIDGE \
|
||||
$MAX_UINT256 \
|
||||
--private-key $PRIVATE_KEY \
|
||||
--rpc-url http://192.168.11.211:8545 \
|
||||
--gas-price 1000000
|
||||
```
|
||||
|
||||
### Step 4: Approve LINK (One-time)
|
||||
```bash
|
||||
cast send 0x362E9a45Ef6e554760f9671938235Cbc9b6E80Ed \
|
||||
"approve(address,uint256)" \
|
||||
$BRIDGE \
|
||||
$MAX_UINT256 \
|
||||
--private-key $PRIVATE_KEY \
|
||||
--rpc-url http://192.168.11.211:8545 \
|
||||
--gas-price 1000000
|
||||
```
|
||||
|
||||
### Step 5: Execute Bridge Transfer
|
||||
```bash
|
||||
DEST_CHAIN="5009297550715157269" # Ethereum Mainnet
|
||||
RECIPIENT="0x4A666F96fC8764181194447A7dFdb7d471b301C8" # Your address
|
||||
AMOUNT="1000000000000000" # 0.001 WETH9
|
||||
|
||||
cast send $BRIDGE \
|
||||
"sendCrossChain(uint64,address,uint256)" \
|
||||
$DEST_CHAIN \
|
||||
$RECIPIENT \
|
||||
$AMOUNT \
|
||||
--private-key $PRIVATE_KEY \
|
||||
--rpc-url http://192.168.11.211:8545 \
|
||||
--gas-limit 500000 \
|
||||
--gas-price 1000000
|
||||
```
|
||||
|
||||
### Step 6: Verify Transaction
|
||||
```bash
|
||||
# Check transaction receipt
|
||||
TX_HASH="your_tx_hash_here"
|
||||
cast receipt $TX_HASH --rpc-url http://192.168.11.211:8545
|
||||
|
||||
# Verify nonce incremented
|
||||
cast call $BRIDGE \
|
||||
"getUserNonce(address)(uint256)" \
|
||||
$RECIPIENT \
|
||||
--rpc-url http://192.168.11.211:8545
|
||||
|
||||
# Check bridge balance (should have locked WETH9)
|
||||
cast call 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2 \
|
||||
"balanceOf(address)(uint256)" \
|
||||
$BRIDGE \
|
||||
--rpc-url http://192.168.11.211:8545
|
||||
```

|
||||
## 🔧 Troubleshooting Guide
|
||||
|
||||
### Issue: "Gas price below configured minimum"
|
||||
**Symptom**: Transaction fails with error code -32009
|
||||
**Cause**: RPC node requires minimum gas price
|
||||
**Solution**: Add `--gas-price 1000000` (1,000,000 wei = 0.000001 gwei)
|
||||
|
||||
```bash
|
||||
# Always use explicit gas price
|
||||
--gas-price 1000000
|
||||
```
|
||||
|
||||
### Issue: "Replacement transaction underpriced"
|
||||
**Symptom**: Transaction fails with nonce conflict
|
||||
**Cause**: Transaction with same nonce already in mempool
|
||||
**Solution**: Wait for previous transaction to confirm or increase gas price
|
||||
|
||||
```bash
|
||||
# Check pending nonce
|
||||
cast nonce $YOUR_ADDRESS --rpc-url http://192.168.11.211:8545
|
||||
|
||||
# Wait 5 seconds and retry
|
||||
sleep 5
|
||||
```
|
||||
|
||||
### Issue: "Destination not enabled"
|
||||
**Symptom**: Bridge transaction reverts
|
||||
**Cause**: Destination chain not configured on bridge
|
||||
**Solution**: Check destination status
|
||||
|
||||
```bash
|
||||
# Verify destination enabled
|
||||
cast call $BRIDGE \
|
||||
"getDestination(uint64)(address,bool)" \
|
||||
5009297550715157269 \
|
||||
--rpc-url http://192.168.11.211:8545
|
||||
|
||||
# Should return: (0x2A0840e5117683b11682ac46f5CF5621E67269E3, true)
|
||||
```
|
||||
|
||||
### Issue: "Insufficient allowance"
|
||||
**Symptom**: Transaction reverts during token transfer
|
||||
**Cause**: Approval not set or consumed
|
||||
**Solution**: Check and reset approvals
|
||||
|
||||
```bash
|
||||
# Check WETH9 allowance
|
||||
cast call 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2 \
|
||||
"allowance(address,address)(uint256)" \
|
||||
$YOUR_ADDRESS \
|
||||
$BRIDGE \
|
||||
--rpc-url http://192.168.11.211:8545
|
||||
|
||||
# If zero, re-approve (see Step 3 above)
|
||||
```
|
||||
|
||||
### Issue: Network Not Producing Blocks
|
||||
**Symptom**: Block number not incrementing
|
||||
**Cause**: Validator quorum lost or mining disabled
|
||||
**Solution**: Check validator status and restart if needed
|
||||
|
||||
```bash
|
||||
# Check latest block age
|
||||
cast block latest --rpc-url http://192.168.11.211:8545 | grep timestamp
|
||||
|
||||
# If > 30 seconds old, validators may need attention
|
||||
# Contact system administrator to check:
|
||||
# - Validator 1000-1002 on r630-01 (192.168.11.11)
|
||||
# - Validator 1003-1004 on ml110 (192.168.11.10)
|
||||
```
|
||||
|
||||
### Issue: Empty Blocks Produced
|
||||
**Symptom**: Blocks produced but transactions not included
|
||||
**Cause**: min-gas-price not set to 0 on validators
|
||||
**Solution**: Already fixed in current configuration
|
||||
|
||||
**Validators must have**:
|
||||
```toml
|
||||
min-gas-price=0
|
||||
permissions-accounts-config-file-enabled=false
|
||||
miner-enabled=true
|
||||
```

|
||||
|
||||
## 🔐 Security Considerations
|
||||
|
||||
### Private Key Management
|
||||
- ⚠️ **NEVER** commit private keys to git
|
||||
- ⚠️ **NEVER** share private keys in plain text
|
||||
- ✅ Use environment variables: `export PRIVATE_KEY="0x..."`
|
||||
- ✅ Use hardware wallets for production
|
||||
- ✅ Rotate keys periodically
|
||||
|
||||
### Admin Functions
|
||||
The bridge admin can:
|
||||
- Add/remove destinations
|
||||
- Pause/unpause the bridge
|
||||
- Update configuration
|
||||
|
||||
**Admin address**: `0x4A666F96fC8764181194447A7dFdb7d471b301C8`
|
||||
|
||||
### Access Control
|
||||
- Only admin can modify bridge configuration
|
||||
- Any user can bridge tokens (no whitelist)
|
||||
- All transactions are transparent on-chain
|
||||
|
||||

|
||||
|
||||
## 🎯 Performance Metrics
|
||||
|
||||
### Expected Performance
|
||||
| Metric | Target | Current |
|
||||
|--------|--------|---------|
|
||||
| Block Time | 2 seconds | ✅ ~2 seconds |
|
||||
| Transaction Confirmation | 1-2 blocks | ✅ <5 seconds |
|
||||
| Bridge Transaction Gas | <200k gas | ✅ ~172k gas |
|
||||
| Network Uptime | >99% | ✅ Stable |
|
||||
|
||||
### Known Limitations
|
||||
|
||||
#### Mock CCIP Environment
|
||||
- ✅ Message emission: Works
|
||||
- ✅ Token locking: Works
|
||||
- ✅ Fee payment: Works
|
||||
- ⚠️ Cross-chain relay: **Not implemented** (mock only)
|
||||
- ⚠️ Message delivery: **Not implemented** (mock only)
|
||||
|
||||
**What this means**:
|
||||
- Tokens are locked in bridge contract ✅
|
||||
- CCIP message is emitted ✅
|
||||
- No actual delivery to real Ethereum Mainnet ⚠️
|
||||
- For production: Connect to real Chainlink CCIP
|
||||
|
||||
#### Gas Price Requirements
|
||||
- Validators accept gas-price=0
|
||||
- RPC node requires gas-price ≥ 1,000,000 wei
|
||||
- Always specify `--gas-price 1000000` when using RPC
|
||||

|
||||
```
|
||||
|
||||
### Emergency Procedures
|
||||
|
||||
#### Network Stopped
|
||||
1. Check all 5 validators are running
|
||||
2. Verify QBFT quorum (need 4/5)
|
||||
3. Check validator logs for errors
|
||||
4. Restart validators if needed
|
||||
5. Wait for network recovery (~5-10 minutes)
|
||||
|
||||
#### Bridge Malfunction
|
||||
1. Check destination configuration
|
||||
2. Verify router has code
|
||||
3. Check token approvals
|
||||
4. Review recent transaction logs
|
||||
5. Contact bridge admin if needed
