📈 Next Steps for You

Immediate (Next Hour)

Start extended monitoring:

# Start bot for production monitoring
PROVIDER_CONFIG_PATH=$PWD/config/providers_runtime.yaml ./mev-bot start

# In another terminal, watch for opportunities
tail -f logs/mev_bot.log | grep -i "arbitrage\|opportunity"

# Monitor parsing health
tail -f logs/mev_bot.log | grep -i "parsing\|success rate"

Short Term (24 Hours)

1. Collect baseline metrics:

   • DEX transaction rate
   • Parsing success rate
   • Opportunity frequency
   • False positive rate

2. Evaluate threshold tuning:

   • If too many false positives → raise thresholds
   • If no opportunities → verify pool/price data
   • If parser issues → check debug logs

Medium Term (Week 1)

Gradual threshold increases:

Current:    0.0001 ETH, 0.05% ROI (testing)
↓
Week 1:     0.0005 ETH, 0.5% ROI  
↓
Week 2:     0.001 ETH, 1.0% ROI
↓
Production: 0.002 ETH, 2.0% ROI

🔍 Monitoring Commands

Essential Monitoring

# Watch for arbitrage opportunities
tail -f logs/mev_bot.log | grep -i "arbitrage\|opportunity"

# Monitor parsing performance  
grep "PARSING PERFORMANCE REPORT" logs/mev_bot.log | tail -10

# Check for any new edge cases (should be 0)
grep "EDGE CASE DETECTED" logs/mev_bot.log | tail -5

# Connection health
grep -i "connection\|dns" logs/mev_bot.log | tail -20

# DEX transaction rate
grep "DEX Transaction detected" logs/mev_bot.log | tail -20

Debug Mode (if needed)

# Enable debug logging for detailed output
LOG_LEVEL=debug PROVIDER_CONFIG_PATH=$PWD/config/providers_runtime.yaml ./mev-bot start

# Watch parser rejections (new logging)
tail -f logs/mev_bot.log | grep "Rejecting"

# Count rejection types
grep "Rejecting" logs/mev_bot.log | awk '{print $6}' | sort | uniq -c

💡 What to Expect

Normal Behavior (First 30-60 Minutes)

• ✅ Bot processing blocks continuously
• ✅ DEX transactions being detected (~1-3 per 10 blocks)
• ✅ No edge case warnings
• ✅ No crashes or errors
• ⏳ No arbitrage opportunities yet (need time to build state)

Success Indicators

After 30-60 minutes, you should see:

• ✅ Parsing success rate > 50%
• ✅ No zero address warnings
• ✅ Stable connection (no reconnects)
• ✅ At least exploration of opportunities

If No Opportunities After 2 Hours

Check these areas:

1. Pool discovery - Are pools being loaded?
2. Price oracle - Are prices being fetched?
3. Arbitrage detection - Is the engine running?
4. Consider lowering thresholds further (0.00005 ETH)

🎓 Key Learnings

Root Cause Analysis

The "perfect storm" of 3 simultaneous bugs:

1. Parser bug: Zero addresses passing validation
2. High thresholds: Too strict for L2 gas costs
3. Network issues: DNS failures causing gaps

Result: Even if parser worked, thresholds prevented detection.

What Fixed It

1. Validation before IsValid=true: Stops corrupted data
2. Lower thresholds: Allows opportunities to be seen
3. More RPC endpoints: Prevents connection gaps
4. Comprehensive logging: Enables debugging

📞 Support & Troubleshooting

If Issues Arise

Parser Problems:

# Check debug logs
LOG_LEVEL=debug ./mev-bot start
grep "Rejecting" logs/mev_bot.log | tail -20

Connection Issues:

# Check RPC health
grep -i "connection\|health" logs/mev_bot.log | tail -20

No Opportunities:

# Verify detection is running
grep "Arbitrage Service Stats" logs/mev_bot.log | tail -10
# Check pool/token loading
grep "Loaded.*from" logs/mev_bot.log | head -10

Rollback Plan

If major issues occur:

# Revert all changes
git checkout pkg/arbitrum/l2_parser.go
git checkout config/arbitrum_production.yaml

# Rebuild
go build -o mev-bot ./cmd/mev-bot

# Restart
./scripts/run.sh
