# Ethereum Mainnet Configuration - Persistent Blocking Issue

**Date**: $(date)  
**Status**: ⚠️ **PERSISTENT MEMPOOL BLOCK - DEEPER INVESTIGATION NEEDED**

---

## 🔍 Issue Summary

Ethereum Mainnet configuration is **persistently blocked** by a stuck transaction in the mempool, even after:
- ✅ Restarting all validators (1000-1004)
- ✅ Restarting all RPC nodes (2500-2502)
- ✅ Restarting all sentries
- ✅ Using extremely high gas prices (up to 100,000 gwei)
- ✅ Trying nonce skipping (rejected by Besu)

**Error**: `Replacement transaction underpriced` (error code -32000)

| BSC | ✅ CONFIGURED |
| Polygon | ✅ CONFIGURED |
| Avalanche | ✅ CONFIGURED |
| Base | ✅ CONFIGURED |
| Arbitrum | ✅ CONFIGURED |
| Optimism | ✅ CONFIGURED |
| **Ethereum Mainnet** | ❌ **BLOCKED** |

### Test Results
- Total Tests: 33
- Passed: 24
- Failed: 1 (Ethereum Mainnet)
- Success Rate: 72.72%

## 🔍 Root Cause Analysis

### Possible Causes

1. **Transaction Persisted in Database**
   - Besu may have persisted the transaction in its database
   - Restarting services doesn't clear persisted transactions
   - Requires database-level clearing

2. **Transaction in Validator Mempool**
   - Transaction may be in a validator's mempool, not RPC
   - Validators don't expose RPC, so can't query directly
   - May need to check validator logs

3. **Transaction Already Mined but Failed**
   - Transaction with nonce 23 may have been mined but failed
   - Nonce stuck because transaction failed
   - Need to check transaction receipt

4. **Besu Configuration Issue**
   - Minimum gas price may be preventing replacement
   - Transaction pool settings may be blocking
   - Account permissioning may be blocking

## 🔧 Investigation Steps Needed

### Step 1: Check Transaction History

```bash
# Check if transaction with nonce 23 was mined
cast tx --rpc-url http://192.168.11.250:8545 <tx_hash>
cast receipt --rpc-url http://192.168.11.250:8545 <tx_hash>
```

### Step 2: Check Validator Logs

On ML110, check validator logs for transaction rejection:

```bash
# On ML110
for vmid in 1000 1001 1002 1003 1004; do
    echo "=== VMID $vmid ==="
    pct exec $vmid -- journalctl -u besu-validator -n 100 | grep -iE "transaction|reject|nonce|23"
done
```

### Step 3: Check Besu Database

The transaction may be persisted. Check if we can clear it:

```bash
# On ML110, check Besu data directory
pct exec 2500 -- ls -la /data/besu/
```

### Step 4: Try Different Account

If mempool persists, try using a different account:

```bash
# Generate new account
cast wallet new

# Fund with ETH
# Then use for configuration
```

---

## 💡 Alternative Solutions

### Solution 1: Clear Besu Database (Nuclear Option)

**WARNING**: This will require re-syncing the node

```bash
# On ML110
pct exec 2500 -- systemctl stop besu-rpc
pct exec 2500 -- rm -rf /data/besu/caches/
pct exec 2500 -- systemctl start besu-rpc
```

### Solution 2: Use Different Deployer Account

Create a new account and use it for configuration:

```bash
# Create new account
NEW_ACCOUNT=$(cast wallet new)
echo "New account: $NEW_ACCOUNT"

# Fund with ETH
# Use for configuration
```

### Solution 3: Check if Transaction Actually Succeeded

The transaction may have succeeded but the nonce didn't advance:

```bash
# Check if Ethereum Mainnet is actually configured
cast call 0x89dd12025bfCD38A168455A44B400e913ED33BE2 \
  "destinations(uint64)" \
  5009297550715157269 \
  --rpc-url http://192.168.11.250:8545
```

## 📋 Next Steps

1. **Investigate transaction history** - Check if nonce 23 transaction was mined
2. **Check validator logs** - Look for transaction rejection reasons
3. **Try different account** - Use a new account to bypass stuck transaction
4. **Check Besu configuration** - Verify minimum gas price and pool settings
5. **Consider database clearing** - If all else fails, clear Besu caches

---

## 🎯 Priority

**HIGH** - Ethereum Mainnet is the only network not configured. All other networks (6/7) are working correctly.
