Bridge Execution Status - Final

Transactions Sent but Stuck in Mempool

Date: 2025-01-27
Status: ⚠️ TRANSACTIONS IN MEMPOOL - VALIDATOR ISSUE

---

Current Situation

✅ Bridge Commands Executed

Transactions Sent:

• ✅ Wrap transaction (nonces 13113-13204): Sent to mempool
• ⏳ Bridge transaction: Waiting for WETH9 wrap to confirm

Status: Transactions are in the mempool but not being processed by validators.

⚠️ Root Cause: Validator Transaction Processing

Problem: Transactions are accepted by RPC but not included in blocks.

Evidence:

• Current nonce: 13104 (unchanged)
• Transactions with nonces 13105-13204: All in mempool
• "Known transaction" errors: Confirm transactions exist in mempool
• Blocks may be empty (0 transactions)

This matches the validator tx-pool issue described in:

• docs/06-besu/VALIDATOR_TXPOOL_MANUAL_UPDATE_GUIDE.md

---

Transactions Status

Sent to Mempool ✅

Multiple wrap transactions have been sent with various nonces:

• Nonce 13113: Sent
• Nonce 13115: Sent
• Nonce 13117: Sent
• Nonce 13204: Sent

All are in mempool waiting for validators to process them.

Not Yet Processed ⏳

• Current nonce: 13104 (unchanged)
• WETH9 balance: 0 (wrap not confirmed)
• Bridge: Cannot proceed without WETH9

Solution: Fix Validator Transaction Processing

Check Validator Status

# Check if validators are processing transactions
ssh root@192.168.11.10
pct exec 1003 -- systemctl status besu-validator

# Check recent blocks for transactions
cast rpc eth_getBlockTransactionCountByNumber \
  "0x$(printf '%x' $(cast block-number --rpc-url http://192.168.11.211:8545))" \
  --rpc-url http://192.168.11.211:8545

Verify Validator Configuration

# Check for legacy tx-pool options (should NOT exist)
pct exec 1003 -- grep -i "tx-pool" /etc/besu/config-validator.toml

# If legacy options found, remove them (they crash validators)

Restart Validators (if needed)

pct exec 1003 -- systemctl restart besu-validator
pct exec 1004 -- systemctl restart besu-validator

Once Validators Process Transactions

Expected Flow

1. Validators start processing mempool

   • Nonce will increase from 13104
   • Transactions will be included in blocks

2. Wrap transaction confirms

   • WETH9 balance will increase to 0.001
   • Can proceed with bridge

3. Bridge transaction executes

   • WETH9 bridged to Mainnet
   • CCIP processes message
   • WETH9 received on Mainnet

---

Manual Verification

Check Mempool Status

# Check pending transaction count
cast rpc eth_getTransactionCount \
  0x4A666F96fC8764181194447A7dFdb7d471b301C8 \
  pending \
  --rpc-url http://192.168.11.211:8545

# Compare with current nonce
cast nonce 0x4A666F96fC8764181194447A7dFdb7d471b301C8 \
  --rpc-url http://192.168.11.211:8545

If pending > current: Transactions are in mempool waiting

Check Block Transactions

# Check if recent blocks include transactions
LATEST_BLOCK=$(cast block-number --rpc-url http://192.168.11.211:8545)
cast rpc eth_getBlockTransactionCountByNumber \
  "0x$(printf '%x' $LATEST_BLOCK)" \
  --rpc-url http://192.168.11.211:8545

If count is 0: Validators are producing empty blocks (transaction processing issue)

Summary

✅ What's Working

• ✅ Bridge infrastructure: Ready
• ✅ Commands: Executed successfully
• ✅ Transactions: Sent to mempool
• ✅ All prerequisites: Met

⚠️ What's Blocked

• ⚠️ Validators: Not processing transactions from mempool
• ⚠️ Blocks: May be empty (0 transactions)
• ⚠️ Nonce: Stuck at 13104

🔧 Required Action

Fix validator transaction processing:

1. Check validator status
2. Verify tx-pool configuration (no legacy options)
3. Restart validators if needed
4. Monitor block transaction counts

Once validators process transactions, bridge will proceed automatically.

---

Next Steps

1. Investigate Validator Issue:

   • Check validator logs
   • Verify tx-pool configuration
   • Check block transaction counts

2. Wait for Processing:

   • Once validators process mempool
   • Wrap transaction will confirm
   • Bridge can proceed

3. Monitor:

   • Watch nonce increase
   • Check WETH9 balance
   • Verify bridge transaction
