CRITICAL BUG FIX: - MultiHopScanner.updateTokenGraph() was EMPTY - adding no pools! - Result: Token graph had 0 pools, found 0 arbitrage paths - All opportunities showed estimatedProfitETH: 0.000000 FIX APPLIED: - Populated token graph with 8 high-liquidity Arbitrum pools: * WETH/USDC (0.05% and 0.3% fees) * USDC/USDC.e (0.01% - common arbitrage) * ARB/USDC, WETH/ARB, WETH/USDT * WBTC/WETH, LINK/WETH - These are REAL verified pool addresses with high volume AGGRESSIVE THRESHOLD CHANGES: - Min profit: 0.0001 ETH → 0.00001 ETH (10x lower, ~$0.02) - Min ROI: 0.05% → 0.01% (5x lower) - Gas multiplier: 5x → 1.5x (3.3x lower safety margin) - Max slippage: 3% → 5% (67% higher tolerance) - Max paths: 100 → 200 (more thorough scanning) - Cache expiry: 2min → 30sec (fresher opportunities) EXPECTED RESULTS (24h): - 20-50 opportunities with profit > $0.02 (was 0) - 5-15 execution attempts (was 0) - 1-2 successful executions (was 0) - $0.02-$0.20 net profit (was $0) WARNING: Aggressive settings may result in some losses Monitor closely for first 6 hours and adjust if needed Target: First profitable execution within 24 hours 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>

# MEV Bot Log Analysis - Quick Summary
|
||
**Date:** October 29, 2025 00:45
|
||
**Status:** 🔴 **CRITICAL ISSUE FOUND**
|
||
|
||
---
|
||
|
||
## 🚨 CRITICAL ISSUE: RPC Rate Limiting
|
||
|
||
**The MEV bot is completely blocked by RPC rate limiting.**
|
||
|
||
### The Problem
|
||
|
||
```
|
||
94.4% of all errors are "429 Too Many Requests"
|
||
21,590 rate limit errors out of 22,856 total errors
|
||
Bot cannot process ANY blocks
|
||
```
|
||
|
||
### Root Cause
|
||
|
||
The bot is using the **PUBLIC** Arbitrum RPC endpoint instead of your **PAID** Chainstack endpoint.
|
||
|
||
```
|
||
Current (WRONG): https://arb1.arbitrum.io/rpc ❌
|
||
Expected (RIGHT): wss://arbitrum-mainnet.core.chainstack.com/YOUR_KEY ✅
|
||
```
|
||
|
||
Public endpoints have strict limits (~10 req/sec), but the bot needs ~100 req/sec.
|
||
|
||
---
|
||
|
||
## 🔧 Quick Fix
|
||
|
||
### Option 1: Automated Fix Script (Recommended)
|
||
|
||
```bash
|
||
cd /home/administrator/projects/mev-beta
|
||
./scripts/fix-rpc-config.sh
|
||
```
|
||
|
||
This will:
|
||
1. Check current configuration
|
||
2. Load correct settings from .env.production
|
||
3. Stop the running bot
|
||
4. Verify configuration
|
||
|
||
### Option 2: Manual Fix
|
||
|
||
```bash
|
||
# 1. Export correct endpoints
|
||
export ARBITRUM_RPC_ENDPOINT="wss://arbitrum-mainnet.core.chainstack.com/YOUR_KEY"
|
||
export ARBITRUM_WS_ENDPOINT="wss://arbitrum-mainnet.core.chainstack.com/YOUR_KEY"
|
||
|
||
# 2. Stop bot if running
|
||
pkill mev-bot
|
||
|
||
# 3. Restart with correct config
|
||
PROVIDER_CONFIG_PATH=$PWD/config/providers_runtime.yaml ./bin/mev-bot start
|
||
|
||
# 4. Monitor logs
|
||
tail -f logs/mev_bot.log | grep "429 Too Many Requests"
|
||
# Should show NO results after fix
|
||
```
|
||
|
||
---
|
||
|
||
## 📊 What Else Was Found?
|
||
|
||
### ✅ Working Correctly
|
||
|
||
1. **Opportunity Detection** - Bot is finding potential trades
|
||
2. **Profit Calculation** - Correctly rejecting unprofitable trades (all 4,093 opportunities)
|
||
3. **Pool Blacklisting** - Invalid pools being identified and skipped
|
||
4. **Logging** - Comprehensive logging working perfectly
|
||
5. **Error Handling** - Proper error wrapping and recovery
|
||
|
||
### ⚠️ Minor Issues
|
||
|
||
1. **Pool slot0() Errors** - Some V2 pools causing errors
|
||
- Status: ✅ Fixed in this session with new PoolDetector
|
||
- Impact: Low (blacklist system working as workaround)
|
||
|
||
2. **Connection Resets** - ~300 TCP connection resets
|
||
- Status: ⚠️ Related to rate limiting
|
||
- Impact: Should resolve when RPC issue fixed
|
||
|
||
### ℹ️ Informational
|
||
|
||
1. **Zero Profitable Opportunities**
|
||
- Status: ✅ Expected
|
||
- Reason: All 4,093 detected opportunities are unprofitable after gas costs
|
||
- This is CORRECT behavior - bot is protecting you from losses!

||
## 🎯 Verification Steps
|
||
|
||
After applying the fix, verify:
|
||
|
||
### 1. No More Rate Limit Errors
|
||
```bash
|
||
tail -f logs/mev_bot.log | grep "429 Too Many Requests"
|
||
# Should show NOTHING
|
||
```
|
||
|
||
### 2. Blocks Being Processed
|
||
```bash
|
||
tail -f logs/mev_bot.log | grep "Processing block"
|
||
# Should show continuous output like:
|
||
# [INFO] Processing block 394532850
|
||
# [INFO] Processing block 394532851
|
||
```
|
||
|
||
### 3. Connected to Chainstack
|
||
```bash
|
||
tail -f logs/mev_bot.log | grep -i "connected"
|
||
# Should show:
|
||
# [INFO] Connected to Arbitrum via wss://arbitrum-mainnet.core.chainstack.com
|
||
```

## 🚀 After Fix: Next Steps
|
||
|
||
Once RPC issue is resolved:
|
||
|
||
1. **Monitor for 1 Hour**
|
||
- Verify no rate limiting
|
||
- Check block processing rate
|
||
- Confirm opportunities being detected
|
||
|
||
2. **Run 24-Hour Validation Test** (recommended)
|
||
```bash
|
||
./scripts/24h-validation-test.sh
|
||
```
|
||
|
||
3. **Review Validation Results**
|
||
- Cache performance (target: 75-85% hit rate)
|
||
- System stability
|
||
- Opportunity detection rate
|
||
|
||
4. **Begin Flash Loan Implementation** (if validation passes)
|
||
- Follow architecture document
|
||
- 4-week implementation plan
