# Nonce 23 Stuck Transaction - Resolution Guide

**Date**: $(date)  
**Status**: ⚠️ **NONCE 23 STUCK WITH EXTREMELY HIGH GAS PRICE**

---

## 🔍 Root Cause Identified

### Issue
- **Nonce 22**: Was incomplete (now resolved)
- **Nonce 23**: Stuck with extremely high gas price (>1,000,000 gwei)
- Cannot replace even with maximum gas prices

### Evidence
- Current nonce: 23
- Attempted replacement with: 1,000,000 gwei
- Error: "Replacement transaction underpriced"
- Transaction NOT found in mined blocks

---

## 📊 Current Status

- **Nonce**: 23 (stuck)
- **Networks Configured**: 6/7 ✅
  - ✅ BSC, Polygon, Avalanche, Base, Arbitrum, Optimism
  - ❌ Ethereum Mainnet (blocked by nonce 23)

---

## 💡 Solution Options

### Option 1: Wait for Transaction Expiration (If Configured)

Some Besu configurations have transaction pool retention periods:
- Check Besu config for `tx-pool-retention-hours`
- Wait for retention period to expire
- Transaction will be automatically removed

**Check retention period**:
```bash
# On ML110
pct exec 2500 -- grep -i "retention" /etc/besu/config-rpc.toml
```

### Option 2: Use Different Deployer Account (RECOMMENDED)

**Advantages**:
- Completely bypasses stuck nonce
- Fast and reliable
- No node restarts needed

**Steps**:
1. Create new account (already created: `0xC13EfAe66708C7541d2D66A2527bcBF9992e7186`)
2. Fund with ETH
3. Use for Ethereum Mainnet configuration

### Option 3: Clear Transaction Pool Database

**WARNING**: Requires stopping nodes

```bash
# On ML110
# Stop RPC node
pct exec 2500 -- systemctl stop besu-rpc

# Clear transaction pool (if accessible)
# Location may vary by Besu version
pct exec 2500 -- find /data/besu -name "*pool*" -type d

# Restart
pct exec 2500 -- systemctl start besu-rpc
```

### Option 4: Wait for Transaction to Mine

If the transaction eventually gets mined (even if it fails), the nonce will advance:
- Monitor nonce: `cast nonce <address> --rpc-url <rpc>`
- Once nonce advances, retry configuration

## 🎯 Recommended Action

**Use Option 2 (Different Account)** - Fastest and most reliable:

1. Fund new account with ETH:
   ```bash
   cast send 0xC13EfAe66708C7541d2D66A2527bcBF9992e7186 \
     --value 10ether \
     --rpc-url http://192.168.11.250:8545 \
     --private-key <ORIGINAL_PRIVATE_KEY> \
     --gas-price 10000000000
   ```

2. Configure Ethereum Mainnet with new account:
   ```bash
   cast send 0x89dd12025bfCD38A168455A44B400e913ED33BE2 \
     "addDestination(uint64,address)" \
     5009297550715157269 \
     0x8078a09637e47fa5ed34f626046ea2094a5cde5e \
     --rpc-url http://192.168.11.250:8545 \
     --private-key <NEW_ACCOUNT_PRIVATE_KEY> \
     --gas-price 10000000000
   ```

## 📋 Investigation Summary

### Completed
- ✅ Nonce 22 identified and resolved
- ✅ Nonce 23 identified as stuck
- ✅ Attempted replacement with 1,000,000 gwei (failed)
- ✅ Validator logs checked (7 pending transactions)
- ✅ Transaction history checked (not mined)
- ✅ Besu caches cleared
- ✅ New account created

### Findings
- Transaction with nonce 23 has gas price >1,000,000 gwei
- Transaction is in validator mempools (not just RPC)
- Transaction persists after cache clearing
- Cannot be replaced with standard methods
