# MEV Bot V2 - Production Safety Checklist

⚠️ **DO NOT SKIP ANY ITEMS** - Each one prevents potential losses

---

## Pre-Deployment (MANDATORY)

### Configuration
- [ ] `.env.production.safe` copied and customized
- [ ] `DRY_RUN_MODE=true` initially
- [ ] `ENABLE_EXECUTION=false` initially
- [ ] Archive RPC provider configured (Alchemy/QuickNode)
- [ ] Private key stored securely (hardware wallet recommended)
- [ ] All safety limits set conservatively

### Testing
- [ ] 24+ hours dry-run monitoring completed
- [ ] Profit calculations manually verified
- [ ] Circuit breaker tested (triggers on losses)
- [ ] Emergency stop tested (creates file successfully)
- [ ] Testnet deployment successful (if applicable)

### Infrastructure
- [ ] Monitoring stack deployed (Prometheus + Grafana)
- [ ] Alerting configured (Slack/Discord/Telegram)
- [ ] Server meets minimum specs (4 CPU, 8GB RAM)
- [ ] Low latency RPC connection verified (<100ms)

---

## Deployment Day

### Initial Launch (Dry-Run)
- [ ] Deploy with `DRY_RUN_MODE=true`
- [ ] Monitor logs continuously for 24 hours
- [ ] Verify opportunities detected correctly
- [ ] Check profit estimates look reasonable
- [ ] No errors or warnings in logs

### Switch to Live Trading (If Dry-Run Successful)
- [ ] Start with `MAX_POSITION_SIZE=0.1` ETH
- [ ] Fund wallet with SMALL amount (0.5-1 ETH max)
- [ ] Set `ENABLE_EXECUTION=true`
- [ ] Monitor EVERY trade for first hour
- [ ] Manually calculate profit/loss for first 10 trades

---

## Daily Monitoring (First Week)

- [ ] Check bot still running
- [ ] Review all trades from last 24 hours
- [ ] Calculate net P/L (including gas costs)
- [ ] Check circuit breaker events
- [ ] Review error logs
- [ ] Verify wallet balance matches expectations

**If ANY day shows net loss: STOP and investigate**

---

## Weekly Review

- [ ] Calculate weekly ROI
- [ ] Win rate > 60%?
- [ ] Gas costs < 30% of profits?
- [ ] No unexpected circuit breaker triggers?
- [ ] System stable (no crashes)?
- [ ] Adjust parameters if needed

**If unprofitable: DO NOT increase limits**

---

## Red Flags - STOP IMMEDIATELY If:

🚨 **Circuit breaker triggering frequently** (>3 times/day)
🚨 **Consecutive losing days** (2+ days)
🚨 **Gas costs exceeding profits**
🚨 **Unexpected large losses** (>0.1 ETH single trade)
🚨 **System errors or crashes**
🚨 **RPC connection issues**

---

## Emergency Procedures

### Immediate Stop
```bash
# Method 1: Emergency file
docker exec mev-bot-v2-production touch /tmp/mev-bot-emergency-stop

# Method 2: Container stop
docker stop mev-bot-v2-production

# Method 3: Kill immediately
docker kill mev-bot-v2-production
```

### Post-Stop Actions
1. Export all logs for analysis
2. Calculate total P/L
3. Identify root cause
4. Fix issues before restart
5. Test fixes on testnet
6. Only restart if confident in fix

---

## Capital Scale-Up (ONLY if Profitable)

| Week | Condition | Max Position | Max Daily Volume |
|------|-----------|--------------|------------------|
| 1 | Testing | 0.1 ETH | 0.5 ETH |
| 2 | Profitable Week 1 | 0.25 ETH | 1 ETH |
| 3 | Profitable Week 2 | 0.5 ETH | 2 ETH |
| 4+ | Profitable Week 3 | 1 ETH+ | 5 ETH+ |

**Rules:**
- Each week must be NET profitable before increasing
- ANY losing week = revert to previous limits
- NEVER increase >2x in single week

---

## Safety Limits (NEVER Exceed Without Testing)

| Parameter | Conservative | Moderate | Aggressive |
|-----------|--------------|----------|------------|
| MAX_POSITION_SIZE | 0.1 ETH | 1 ETH | 5 ETH |
| MAX_DAILY_VOLUME | 0.5 ETH | 5 ETH | 20 ETH |
| MIN_PROFIT_WEI | 0.05 ETH | 0.02 ETH | 0.01 ETH |
| MIN_ROI | 5% | 2% | 1% |
| MAX_SLIPPAGE_BPS | 100 (1%) | 200 (2%) | 300 (3%) |
| MAX_GAS_PRICE_GWEI | 25 | 50 | 100 |

**Start conservative, increase gradually ONLY if profitable**

---

## Required Metrics Tracking

### Profitability
- [ ] Gross profit per trade
- [ ] Net profit after gas
- [ ] ROI percentage
- [ ] Win rate
- [ ] Largest win/loss

### Safety
- [ ] Circuit breaker triggers
- [ ] Emergency stops
- [ ] Daily volume used
- [ ] Position size violations

### Performance
- [ ] Trade execution latency
- [ ] Gas cost per trade
- [ ] Failed transaction rate
- [ ] Opportunities detected vs executed

**Remember: It's better to miss opportunities than lose capital**

**Start small, scale slowly, stop quickly if problems occur**
