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 - Quick Fix Checklist
|
|
**Date:** October 29, 2025
|
|
**Issue:** RPC Rate Limiting (CRITICAL)
|
|
|
|
---
|
|
|
|
## ⚡ 5-Minute Fix
|
|
|
|
### Step 1: Run the Fix Script (EASIEST)
|
|
|
|
```bash
|
|
cd /home/administrator/projects/mev-beta
|
|
./scripts/fix-rpc-config.sh
|
|
```
|
|
|
|
✅ This automatically:
|
|
- Checks current config
|
|
- Loads correct settings
|
|
- Stops bot if running
|
|
- Verifies configuration
|
|
|
|
---
|
|
|
|
### Step 2: Restart the Bot
|
|
|
|
```bash
|
|
# Start bot with correct configuration
|
|
PROVIDER_CONFIG_PATH=$PWD/config/providers_runtime.yaml ./bin/mev-bot start
|
|
```
|
|
|
|
---
|
|
|
|
### Step 3: Verify (1 minute)
|
|
|
|
```bash
|
|
# Should show NO "429 Too Many Requests" errors
|
|
tail -100 logs/mev_bot.log | grep "429 Too Many Requests"
|
|
|
|
# Should show blocks being processed
|
|
tail -100 logs/mev_bot.log | grep "Processing block"
|
|
|
|
# Should show connection to Chainstack
|
|
tail -100 logs/mev_bot.log | grep -i "connected"
|
|
```
|
|
|

## 🆘 If Fix Doesn't Work
|
|
|
|
### Check 1: Environment Variables
|
|
|
|
```bash
|
|
echo $ARBITRUM_RPC_ENDPOINT
|
|
# Should show: wss://arbitrum-mainnet.core.chainstack.com/YOUR_KEY
|
|
# NOT: https://arb1.arbitrum.io/rpc
|
|
```
|
|
|
|
### Check 2: .env.production File
|
|
|
|
```bash
|
|
cat .env.production | grep ARBITRUM_RPC
|
|
# Should have Chainstack endpoint, NOT public endpoint
|
|
```
|
|
|
|
### Check 3: Provider Config
|
|
|
|
```bash
|
|
cat config/providers_runtime.yaml | grep endpoint
|
|
# Should show Chainstack endpoints with high weight
|
|
```
|
|
|
|
### Still Having Issues?
|
|
|
|
1. Check logs: `docs/LOG_ANALYSIS_20251029.md`
|
|
2. Review deployment guide: `docs/PRODUCTION_DEPLOYMENT_RUNBOOK.md`
|
|
3. Verify Chainstack API key is valid
|
|
4. Check Chainstack dashboard for usage limits
|
