**Date**: 2026-01-24  
**Status**: ✅ **READY TO BRIDGE** (using nonce bypass method)

---

## 🎯 TL;DR - What You Need to Do

```bash
cd /home/intlc/projects/proxmox
export PRIVATE_KEY="0xYourPrivateKeyHere"
./scripts/test-bridge-with-fresh-nonce.sh
```

Then follow the commands it provides to execute the bridge.

## ⚠️ Known Issue: Stuck Transactions

**Problem**: Nonce stuck at 13104 in RPC mempool  
**Solution**: Bypass stuck transactions by using the correct nonce  
**Impact**: None - we can work around this

---

## 🚀 Bridge Now (3 Simple Steps)

### Step 1: Run Test Script

```bash
cd /home/intlc/projects/proxmox
export PRIVATE_KEY="0xYourPrivateKeyHere"
./scripts/test-bridge-with-fresh-nonce.sh
```

**What it does**:
- Wraps ETH to WETH9 (if needed)
- Approves bridge contract (if needed)
- Tells you the exact command to execute the bridge

### Step 2: Execute Bridge Command

The script will output something like:

```bash
cast send 0x89dd12025bfCD38A168455A44B400e913ED33BE2 \
  'sendCrossChain(uint64,address,uint256)' \
  5009297550715157269 \
  0x4A666F96fC8764181194447A7dFdb7d471b301C8 \
  1000000000000000 \
  --private-key $PRIVATE_KEY \
  --rpc-url http://192.168.11.211:8545 \
  --gas-limit 200000 \
  --gas-price 1000000000 \
  --nonce 13104
```

Copy and run it.

### Step 3: Wait for CCIP

- **Time**: 1-5 minutes
- **Monitor**: Use the transaction hash to track progress
- **Result**: WETH9 appears on Ethereum Mainnet

## 📊 Key Addresses

### ChainID 138
- **WETH9**: `0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2`
- **Bridge**: `0x89dd12025bfCD38A168455A44B400e913ED33BE2`
- **RPC**: `http://192.168.11.211:8545`

### Ethereum Mainnet
- **Bridge**: `0x2A0840e5117683b11682ac46f5CF5621E67269E3`
- **Selector**: `5009297550715157269`

## 🔍 Troubleshooting

### "Nonce too low"
Run the test script again - it will find the correct nonce.

### "Insufficient allowance"
The test script will approve automatically. Just run it.

### "Account balance too low"
Your account has 999M+ ETH. This shouldn't happen.

### Transaction not confirming
Check if validators are still running:
```bash
ssh root@192.168.11.10 "pct exec 1003 -- systemctl status besu-validator"
```

---

## 📝 What Was Fixed

### Validator Configuration ✅
- **Issue**: Validators had no TX-pool configuration
- **Fix**: Added layered TX-pool settings to both validators
- **Config**:
  ```toml
  tx-pool-max-future-by-sender=200
  tx-pool-layer-max-capacity=12500000
  tx-pool-max-prioritized=2000
  ```
- **Status**: Complete

### Stuck Transactions ⚠️
- **Issue**: Old transactions stuck at nonce 13104
- **Attempted**: Restarted 7 RPC nodes
- **Result**: RPC at 192.168.11.211 still has stuck transactions
- **Workaround**: Bypass by using correct nonce (automated in script)

---

## 💡 Why This Works

1. **Validators are configured correctly** - They can process transactions
2. **Network is operational** - Blocks are being produced
3. **Stuck transactions are not on-chain** - They're only in RPC mempool
4. **We can bypass them** - By using the next available nonce
5. **New transactions will process** - Validators will include them in blocks

---

## 🎯 Success Indicators

After running the bridge:

1. ✅ Transaction hash returned
2. ✅ Transaction confirms on ChainID 138
3. ✅ CCIP processes the message (1-5 min)
4. ✅ WETH9 appears on Ethereum Mainnet
