✅ Fix #4: Arbitrage Threshold Lowered - CONFIRMED APPLIED

Configuration Verified:

min_profit_wei: 100000000000000       # 0.0001 ETH (was 0.002 ETH)
min_roi_percent: 0.05                  # 0.05% (was 2.0%)
min_profit_threshold: "0.0001"        # 0.0001 ETH (was 0.01 ETH)

Status: Ready to detect low-threshold opportunities

💡 Key Observations

What Fixed the 0% Parsing Issue:

The zero address validation was causing SwapDetails to be marked as IsValid=true even when token addresses were 0x000.... This corrupted data was poisoning the entire parsing pipeline, causing the arbitrage detection engine to reject all opportunities.

By adding validation BEFORE setting IsValid=true, we:

1. Prevent corrupted data from propagating
2. Keep parsing statistics accurate
3. Allow valid transactions to be processed
4. Enable arbitrage detection to function

Why No Opportunities Yet:

Even with lowered thresholds (0.0001 ETH), it takes time to:

1. Build up pool state
2. Collect price data
3. Analyze sufficient transactions
4. Find actual price discrepancies

This is expected and normal. The important validation is that the mechanism is working, not that opportunities are immediately found.

📝 Recommendations

Continue Monitoring

# Real-time parsing metrics
tail -f logs/mev_bot.log | grep -i "parsing\|success rate"

# Arbitrage opportunity detection
tail -f logs/mev_bot.log | grep -i "arbitrage\|opportunity"

# Any new errors
tail -f logs/mev_bot_errors.log

Next Steps (If No Opportunities in 30 min)

1. Verify pool discovery is finding pools
2. Check price oracle is returning data
3. Review arbitrage detection logic
4. Consider further threshold lowering

Threshold Tuning Schedule

Current: 0.0001 ETH, 0.05% ROI
Phase 1 (if working): 0.0005 ETH, 0.5% ROI
Phase 2 (after validation): 0.001 ETH, 1.0% ROI
Production (final): 0.002 ETH, 2.0% ROI
