# Ethereum Mainnet Configuration Status

**Date**: $(date)  
**Status**: ⚠️ **BLOCKED BY MEMPOOL ISSUE**

---

## 🔍 Issue Analysis

### Problem
Ethereum Mainnet destination configuration is failing with error:
```
Error: server returned an error response: error code -32000: Replacement transaction underpriced
```

### Root Cause
There appears to be a transaction stuck in the mempool (likely with nonce 23) that has a very high gas price. Any attempt to send a replacement transaction fails because the existing pending transaction has a higher gas price.

### Investigation Results

1. **Nonce Status**:
   - Current nonce: 23
   - Pending nonce: 23 (no visible pending transactions)
   - However, error suggests transaction exists in mempool

2. **Transaction History**:
   - No visible pending transactions via nonce check
   - Error persists even with extremely high gas prices (10,000 gwei)
   - Attempted with nonce 24 - transaction sent but timeout occurred

3. **Network Status**:
   - RPC is responding normally
   - Current block: 83446+
   - Gas price: ~1000 wei (very low for private network)

4. **Allocation Issues**:
   - No memory allocation errors found in logs
   - No out-of-memory issues detected
   - Logs show normal compilation errors (unrelated)

## 🔧 Attempted Solutions

1. ✅ **Cancel Pending Transactions Script**
   - Created `scripts/cancel-pending-transactions.sh`
   - No pending transactions detected via nonce check

2. ✅ **High Gas Price Attempts**
   - Tried gas prices: 50 gwei, 100 gwei, 10,000 gwei
   - All failed with "Replacement transaction underpriced"

3. ✅ **Nonce Skipping**
   - Attempted to use nonce 24 to skip stuck transaction
   - Transaction sent but timed out (may be processing)

4. ✅ **Force Configuration Script**
   - Created `scripts/force-configure-ethereum-mainnet.sh`
   - Uses extreme gas prices but still fails

## 💡 Recommended Solutions

### Option 1: Wait and Retry (Recommended)
The transaction with nonce 24 may be processing. Wait 5-10 minutes and check:
```bash
cast call 0x89dd12025bfCD38A168455A44B400e913ED33BE2 \
  "destinations(uint64)" \
  5009297550715157269 \
  --rpc-url http://192.168.11.250:8545
```

### Option 2: Clear Mempool (If Possible)
If you have access to the node:
- Restart the Besu node to clear mempool
- Or use admin RPC to clear pending transactions

### Option 3: Use Different Account
Deploy bridges using a different account/private key to bypass the stuck transaction.

### Option 4: Manual Configuration via Block Explorer
If the network has a block explorer with transaction builder, configure manually.

## 🎯 Next Steps

1. **Wait 10 minutes** and check if nonce 24 transaction was successful
2. **Verify configuration**:
   ```bash
   ./scripts/test-bridge-all-7-networks.sh weth9
   ```
3. **If still blocked**, consider:
   - Restarting the Besu node
   - Using a different account
   - Manual configuration via admin tools
