# 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"
```

---

## ✅ Success Criteria

After fix, you should see:

| Check | Expected | Command |
|-------|----------|---------|
| **No 429 errors** | 0 occurrences | `grep "429" logs/mev_bot.log \| tail -10` |
| **Blocks processing** | Continuous | `grep "Processing block" logs/mev_bot.log \| tail -10` |
| **Chainstack connection** | Connected | `grep "chainstack" logs/mev_bot.log \| tail -10` |

## 🆘 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

## 📞 Quick Reference

**Current Status:** 🔴 Rate Limited (94.4% of operations failing)

**Root Cause:** Using public RPC instead of paid Chainstack endpoint

**Fix Time:** 5 minutes

**Risk:** None (configuration-only change)

**Impact:** Fixes 94.4% of all errors immediately
