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:

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.

📊 Current Bridge Status

Configured Networks (6/7)

• ✅ BSC
• ✅ Polygon
• ✅ Avalanche
• ✅ Base
• ✅ Arbitrum
• ✅ Optimism

Pending Networks (1/7)

• ⚠️ Ethereum Mainnet (blocked by mempool issue)

🎯 Next Steps

1. Wait 10 minutes and check if nonce 24 transaction was successful
2. Verify configuration:

   ./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
