### **Step 4: Configure Encrypted Keystore** ✅ **[AUTOMATED]**

Once wallet is funded and verified, run:

```bash
./scripts/setup-keystore.sh
```

**What This Does:**
- ✅ Derives wallet address from private key
- ✅ Generates secure encryption key (MEV_BOT_ENCRYPTION_KEY)
- ✅ Creates encrypted keystore JSON file
- ✅ Verifies encryption/decryption integrity
- ✅ Sets proper file permissions (600)
- ✅ Saves to `keystore/production/executor_wallet.json`

**Expected Output:**
```
═══════════════════════════════════════════════════════════
🔐 MEV Bot Keystore Configuration
═══════════════════════════════════════════════════════════

✅ Generated and saved encryption key to .env.production
✅ Wallet Address: 0x...
✅ Encrypted keystore created: keystore/production/executor_wallet.json
✅ Keystore verification successful!

═══════════════════════════════════════════════════════════
✅ Keystore Configuration Complete!
═══════════════════════════════════════════════════════════

📋 Summary:
  • Wallet Address: 0x...
  • Keystore File: keystore/production/executor_wallet.json
  • Encryption: AES-256-CBC
  • Network: Arbitrum One

🔒 Security:
  • Private key encrypted with MEV_BOT_ENCRYPTION_KEY
  • Keystore file permissions: 600 (owner read/write only)
```

**Keystore Structure:**
```json
{
  "version": 1,
  "address": "0x...",
  "crypto": {
    "cipher": "aes-256-cbc",
    "ciphertext": "[encrypted-private-key]"
  },
  "metadata": {
    "created": "2025-10-29T...",
    "purpose": "MEV Bot Executor Wallet",
    "network": "Arbitrum One (Chain ID: 42161)"
  }
}
```

---

### **Step 5: Enable Execution Mode** ✅ **[AUTOMATED]**

Enable live trading by running:

```bash
./scripts/enable-execution-mode.sh
```

**What This Does:**
- ✅ Verifies keystore is configured
- ✅ Checks wallet balance
- ✅ Backs up current configuration
- ✅ Updates `config/bot_config.yaml` with execution settings
- ✅ Configures flash loan settings (Balancer + Uniswap)
- ✅ Sets safety limits (gas, slippage, profit thresholds)

**Configuration Changes:**
```yaml
# Key Changes Made:
mode: "execution"                    # Changed from "monitoring"
execution:
  enabled: true                      # Live trading enabled
  dry_run: false                     # Real transactions
  min_profit_usd: 10.0               # $10 minimum profit
  min_profit_percentage: 0.1         # 0.1% minimum
  max_gas_price_gwei: 0.5            # Max gas willing to pay
  flash_loan_enabled: true           # Capital-free trading
  preferred_flash_loan_provider: "balancer"  # 0% fee
  keystore_path: "keystore/production/executor_wallet.json"
```

**Safety Features:**
- ✅ Slippage protection (max 1%)
- ✅ Gas cost limits (max $1 per trade)
- ✅ Front-run protection
- ✅ Position size limits (max 10 ETH flash loan)
- ✅ Rate limiting (5 trades/min, 200 trades/day)
- ✅ Confidence scoring (min 70%)

### **Step 6: Restart Bot** 🚀 **[FINAL STEP]**

Start the bot in execution mode:

```bash
# Kill existing bot (if running)
pkill -f mev-beta

# Start with production configuration
cd /home/administrator/projects/mev-beta
GO_ENV=production nohup ./bin/mev-beta start > logs/mev_bot_production.log 2>&1 &

# Get process ID
echo "Bot started with PID: $(pgrep -f mev-beta)"
```

**Alternative (foreground with live logs):**
```bash
pkill -f mev-beta
GO_ENV=production ./bin/mev-beta start
```

**Verify Startup:**
```bash
# Check bot is running
ps aux | grep mev-beta

# Watch startup logs
tail -f logs/mev_bot.log | grep "Starting\|Execution mode\|Keystore"
```

**Expected Startup Messages:**
```
[INFO] Starting MEV Bot v1.0.0
[INFO] Mode: execution (live trading enabled)
[INFO] Keystore loaded: keystore/production/executor_wallet.json
[INFO] Wallet address: 0x...
[INFO] Flash loans enabled: Balancer (0% fee)
[INFO] Connected to Arbitrum One (Chain ID: 42161)
[INFO] Multi-hop scanner initialized
[INFO] Monitoring for arbitrage opportunities...
```

---

## 📊 Monitoring Execution

### **Real-Time Log Monitoring**

```bash
# Watch all execution activity
tail -f logs/mev_bot.log | grep "EXECUTION\|Executing\|Profit"

# Watch for opportunities detected
tail -f logs/mev_bot.log | grep "Opportunity detected"

# Watch for successful trades
tail -f logs/mev_bot.log | grep "Transaction submitted\|Trade confirmed"

# Watch for errors
tail -f logs/mev_bot.log | grep "ERROR\|Failed"
```

### **What to Look For:**

**Successful Execution Example:**
```
[INFO] Opportunity detected: WETH → USDC → ARB → WETH
[INFO] Expected profit: $45.30 (2.3%), Confidence: 95%
[INFO] Flash loan initiated: 5.0 ETH from Balancer
[INFO] Executing arbitrage on-chain...
[INFO] Transaction submitted: 0x1234...
[INFO] ✅ Trade confirmed! Profit: $43.80 (after gas: $1.50)
[INFO] Wallet balance: 0.0297 ETH (profit added)
```

**Failed Execution (Common, Expected):**
```
[WARN] Opportunity detected but rejected: profit below threshold ($8.50 < $10.00)
[WARN] Trade simulation failed: insufficient liquidity
[INFO] Opportunity expired: price moved before execution
```

### **Metrics Dashboard**

```bash
# Prometheus metrics endpoint
curl http://localhost:9090/metrics

# Key Metrics:
# - mev_opportunities_detected_total
# - mev_trades_executed_total
# - mev_profit_usd_total
# - mev_gas_spent_eth_total
# - mev_execution_latency_seconds
```

### **Wallet Monitoring**

```bash
# Check wallet balance
./scripts/check-wallet-balance.sh

# View on Arbiscan (replace with your address)
open "https://arbiscan.io/address/0xYourWalletAddress"

# Set up balance alerts (refill when low)
watch -n 60 './scripts/check-wallet-balance.sh | grep Balance'
```

---

## 🛑 Emergency Stop

If you need to stop execution immediately:

```bash
# Method 1: Kill bot process
pkill -f mev-beta

# Method 2: Disable execution in config
sed -i 's/enabled: true/enabled: false/g' config/bot_config.yaml

# Method 3: Move keystore (bot can't execute without it)
mv keystore/production/executor_wallet.json keystore/production/executor_wallet.json.disabled
```

**Restart in Monitoring-Only Mode:**
```bash
# Edit config
sed -i 's/mode: "execution"/mode: "monitoring"/g' config/bot_config.yaml

# Restart bot
pkill -f mev-beta
GO_ENV=production nohup ./bin/mev-beta start > logs/mev_bot_production.log 2>&1 &
```

---

## 📈 Expected Performance

### **Conservative Estimates** (0.03 ETH gas budget)

- **Opportunities/Day:** 50-200 detected
- **Executed Trades/Day:** 5-20 (only most profitable)
- **Avg Profit/Trade:** $15-50 (after gas)
- **Daily Profit:** $75-400
- **Weekly ROI:** 10-50x gas investment
- **Gas Refill Needed:** Every 1-2 weeks

### **Aggressive Estimates** (0.05 ETH gas budget, optimal conditions)

- **Opportunities/Day:** 100-500 detected
- **Executed Trades/Day:** 20-50
- **Avg Profit/Trade:** $20-100
- **Daily Profit:** $200-1000+
- **Weekly ROI:** 20-100x gas investment
- **Gas Refill Needed:** Every 2-4 weeks

**Note:** Actual performance varies based on:
- Market volatility (higher = more opportunities)
- Network congestion (lower = cheaper gas)
- Competition (other MEV bots)
- DEX liquidity depth
- Flash loan availability

## 🔒 Security Best Practices

### **Wallet Security**
- ✅ **Dedicated Wallet**: Never use your main wallet for bot execution
- ✅ **Minimal Funding**: Start with 0.01-0.02 ETH, add more as needed
- ✅ **Regular Monitoring**: Check balance and transactions daily
- ✅ **Backup Private Key**: Store encrypted backup in password manager
- ✅ **Never Share**: Private key and encryption key are secrets

### **Operational Security**
- ✅ **Monitor Logs**: Watch for suspicious activity or failed trades
- ✅ **Set Alerts**: Get notified of low balance or errors
- ✅ **Regular Restarts**: Restart bot weekly to clear memory
- ✅ **Update Configs**: Review and adjust thresholds based on performance
- ✅ **Withdraw Profits**: Periodically move profits to main wallet

### **Files to Protect**
```bash
# NEVER commit to git:
keystore/                          # Contains encrypted wallet
.env.production                    # Contains encryption key
/tmp/wallet_key.txt                # Contains plaintext private key

# Already in .gitignore:
keystore/
.env*
*.key
*.pem
```

## ❓ Troubleshooting

### **Problem: Bot won't start**
```bash
# Check logs for errors
tail -100 logs/mev_bot.log

# Common issues:
# 1. Keystore path incorrect
# 2. Encryption key not set
# 3. Wallet not funded
# 4. RPC endpoints unreachable

# Verify config
cat config/bot_config.yaml | grep -A 5 "execution:"
cat .env.production | grep MEV_BOT_ENCRYPTION_KEY
```

### **Problem: No trades executing**
```bash
# Check if opportunities are being detected
tail -f logs/mev_bot.log | grep "Opportunity detected"

# Possible reasons:
# 1. Market conditions not favorable
# 2. Profit threshold too high (try lowering min_profit_usd)
# 3. Gas price too high
# 4. All opportunities below confidence threshold

# Adjust thresholds (edit config/bot_config.yaml)
min_profit_usd: 5.0                # Lower from 10.0
min_confidence_score: 0.6          # Lower from 0.7
```

### **Problem: Trades failing**
```bash
# Check for failed transactions
tail -f logs/mev_bot.log | grep "Failed\|Reverted\|ERROR"

# Common failures:
# 1. Insufficient gas (increase max_gas_price_gwei)
# 2. Slippage too high (opportunity expired)
# 3. Flash loan failed (provider unavailable)
# 4. Front-run by another bot (expected, normal)

# Check wallet has gas
./scripts/check-wallet-balance.sh
```

### **Problem: Low balance**
```bash
# Check current balance
./scripts/check-wallet-balance.sh

# Refill instructions shown in output
# Send more ETH to your wallet address on Arbitrum One

# Temporary: Reduce trade frequency
# Edit config/bot_config.yaml:
max_trades_per_minute: 2           # Lower from 5
```
