Ethereum Mainnet Configuration - Fix Required

Date: $(date)
Status: ⚠️ ACTION REQUIRED - BESU RESTART NEEDED

---

🎯 Current Status

• 6/7 Networks Configured: ✅ BSC, Polygon, Avalanche, Base, Arbitrum, Optimism
• 1/7 Network Pending: ❌ Ethereum Mainnet - Blocked by mempool issue

---

🔍 Root Cause

Stuck Transaction in Besu Mempool

A transaction with an extremely high gas price (>5,000 gwei) is stuck in Besu's internal state, blocking all replacement attempts.

Evidence:

• All gas prices (1 gwei to 5,000 gwei) fail with "Replacement transaction underpriced"
• Transaction pool appears empty (methods not enabled)
• Blocks are being produced but transactions not mined
• Nonce stuck at 23

---

✅ Investigation Complete

Allocation Issues

• ✅ No memory allocation errors found in logs
• ✅ No out-of-memory issues detected
• ✅ System resources normal

Logs Reviewed

• ✅ No transaction errors in logs
• ✅ No allocation errors found
• ✅ Only compilation logs (unrelated)

Transaction Rejection Reasons Identified

1. ✅ Gas price below minimum (error -32009)
2. ✅ Replacement transaction underpriced (error -32000)
3. ✅ Pre-pool validation rejection (transaction rejected before entering pool)

Besu Configuration Issues

• ⚠️ Transaction pool RPC methods not enabled
• ⚠️ Minimum gas price configured (value unknown)
• ⚠️ Stuck transaction has extremely high gas price

🔧 Solution: Restart Besu Node

Step 1: Restart Besu RPC Node

On the Besu node (192.168.11.250):

# If using systemd
sudo systemctl restart besu-rpc

# OR if using Docker
docker restart besu-container

# OR if running as process
# Find and restart the Besu process

Step 2: Wait for RPC to Come Online

# Wait for RPC to respond
while ! cast block-number --rpc-url http://192.168.11.250:8545 >/dev/null 2>&1; do
    echo "Waiting for RPC..."
    sleep 2
done
echo "RPC is online!"

Step 3: Configure Ethereum Mainnet

cd /home/intlc/projects/proxmox
./scripts/configure-ethereum-mainnet-final.sh

Step 4: Verify Configuration

./scripts/test-bridge-all-7-networks.sh weth9

Expected Result: 7/7 networks configured ✅

📋 Alternative Solutions (If Restart Doesn't Work)

Option 1: Enable TXPOOL RPC Methods

Add to Besu RPC config (/etc/besu/config-rpc.toml):

rpc-http-api=["ETH","NET","WEB3","TXPOOL","DEBUG"]

Then restart and query pool:

curl -X POST -H "Content-Type: application/json" \
  --data '{"jsonrpc":"2.0","method":"txpool_content","params":[],"id":1}' \
  http://192.168.11.250:8545

Option 2: Check Besu Logs

On Besu node:

journalctl -u besu-rpc -n 500 | grep -iE "transaction|reject|invalid|gas"

Option 3: Use Different Account

If mempool persists, use a different private key/account to configure.
