# MEV Bot L2 Deployment Guide
|
||||
|
||||
## 🚀 Production Deployment - Arbitrum L2 Optimized
|
||||
|
||||
This guide covers deploying the MEV bot with full L2 message processing capabilities for maximum competitive advantage on Arbitrum.
|
||||
|
||||
## Prerequisites
|
||||
|
||||
### System Requirements
|
||||
- **CPU**: 8+ cores (16+ recommended for high-frequency L2 processing)
|
||||
- **RAM**: 16GB minimum (32GB+ recommended)
|
||||
- **Storage**: 100GB SSD (fast I/O for L2 message processing)
|
||||
- **Network**: High-bandwidth, low-latency connection to Arbitrum nodes
|
||||
|
||||
### Required Services
|
||||
- **Arbitrum RPC Provider**: Alchemy, Infura, or QuickNode (WebSocket support required)
|
||||
- **Monitoring**: Prometheus + Grafana (optional but recommended)
|
||||
- **Alerting**: Slack/Discord webhooks for real-time alerts
|
||||
|
||||
## Quick Start
|
||||
|
||||
### 1. Clone and Build
|
||||
```bash
|
||||
git clone https://github.com/your-org/mev-beta.git
|
||||
cd mev-beta
|
||||
go build -o mev-bot ./cmd/mev-bot/main.go
|
||||
```
|
||||
|
||||
### 2. Environment Setup
|
||||
```bash
|
||||
# Create environment file
|
||||
cat > .env << EOF
|
||||
# Arbitrum L2 Configuration
|
||||
ARBITRUM_RPC_ENDPOINT="wss://arb-mainnet.g.alchemy.com/v2/YOUR_ALCHEMY_KEY"
|
||||
ARBITRUM_WS_ENDPOINT="wss://arb-mainnet.g.alchemy.com/v2/YOUR_ALCHEMY_KEY"
|
||||
|
||||
# Performance Tuning
|
||||
BOT_MAX_WORKERS=25
|
||||
BOT_CHANNEL_BUFFER_SIZE=1000
|
||||
BOT_POLLING_INTERVAL=0.25
|
||||
|
||||
# Monitoring
|
||||
METRICS_ENABLED=true
|
||||
METRICS_PORT=9090
|
||||
|
||||
# Alerting
|
||||
SLACK_WEBHOOK="https://hooks.slack.com/services/YOUR/SLACK/WEBHOOK"

||||
DISCORD_WEBHOOK="https://discord.com/api/webhooks/YOUR/DISCORD/WEBHOOK"
|
||||
EOF
|
||||
```
|
||||
|
||||
### 3. Production Configuration
|
||||
```bash
|
||||
# Copy production config
|
||||
cp config/config.production.yaml config/config.yaml
|
||||
|
||||
# Update with your API keys
|
||||
sed -i 's/YOUR_ALCHEMY_KEY/your-actual-key/g' config/config.yaml
|
||||
sed -i 's/YOUR_INFURA_KEY/your-actual-key/g' config/config.yaml
|
||||
```
|
||||
|
||||
### 4. Start the Bot
|
||||
```bash
|
||||
# With environment variables
|
||||
source .env && ./mev-bot start
|
||||
|
||||
# Or with direct flags
|
||||
METRICS_ENABLED=true ./mev-bot start
|
||||
```
|
||||
|
||||

### Monitoring Setup
|
||||
|
||||
#### Prometheus Configuration
|
||||
```yaml
|
||||
# monitoring/prometheus.yml
|
||||
global:
|
||||
scrape_interval: 15s
|
||||
|
||||
scrape_configs:
|
||||
- job_name: 'mev-bot'
|
||||
static_configs:
|
||||
- targets: ['mev-bot:9090']
|
||||
scrape_interval: 5s
|
||||
metrics_path: '/metrics/prometheus'
|
||||
```
|
||||
|
||||
#### Grafana Dashboard
|
||||
```json
|
||||
{
|
||||
"dashboard": {
|
||||
"title": "MEV Bot L2 Monitoring",
|
||||
"panels": [
|
||||
{
|
||||
"title": "L2 Messages/Second",
|
||||
"type": "graph",
|
||||
"targets": [
|
||||
{
|
||||
"expr": "mev_bot_l2_messages_per_second"
|
||||
}
|
||||
]
|
||||
},
|
||||
{
|
||||
"title": "Net Profit (ETH)",
|
||||
"type": "singlestat",
|
||||
"targets": [
|
||||
{
|
||||
"expr": "mev_bot_net_profit_eth"
|
||||
}
|
||||
]
|
||||

|
||||
{
|
||||
"title": "Error Rate",
|
||||
"type": "graph",
|
||||
"targets": [
|

|
||||
}
|
||||
]
|
||||
}
|
||||
]
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Performance Optimization
|
||||
|
||||
### L2 Message Processing Tuning
|
||||
|
||||
#### High-Frequency Settings
|
||||
```yaml
|
||||
# config/config.yaml
|
||||
bot:
|
||||
polling_interval: 0.1 # 100ms polling
|
||||
max_workers: 50 # High worker count
|
||||
channel_buffer_size: 2000 # Large buffers
|
||||
|
||||
arbitrum:
|
||||
rate_limit:
|
||||
requests_per_second: 100 # Aggressive rate limits
|
||||
max_concurrent: 50
|
||||
burst: 200
|
||||
```
|
||||
|
||||
#### Memory Optimization
|
||||
```bash
|
||||
# System tuning
|
||||
echo 'vm.swappiness=1' >> /etc/sysctl.conf
|
||||
echo 'net.core.rmem_max=134217728' >> /etc/sysctl.conf
|
||||
echo 'net.core.wmem_max=134217728' >> /etc/sysctl.conf
|
||||
sysctl -p
|
||||
```
|
||||
|
||||
### Database Optimization
|
||||
```yaml
|
||||
database:
|
||||
max_open_connections: 100
|
||||
max_idle_connections: 50
|
||||
connection_max_lifetime: "1h"
|
||||
```
|
||||
|
||||
## Security Configuration
|
||||
|
||||
### Network Security
|
||||
```bash
|
||||
# Firewall rules
|
||||
ufw allow 22/tcp # SSH
|
||||
ufw allow 9090/tcp # Metrics (restrict to monitoring IPs)
|
||||
ufw allow 8080/tcp # Health checks (restrict to load balancer)
|
||||
ufw deny 5432/tcp # Block database access
|
||||
ufw enable
|
||||
```
|
||||
|
||||
### API Key Security
|
||||
```bash
|
||||
# Use environment variables, never hardcode
|
||||
export ARBITRUM_RPC_ENDPOINT="wss://..."
|
||||
export ALCHEMY_API_KEY="..."
|
||||
|
||||
# Or use secrets management
|
||||
kubectl create secret generic mev-bot-secrets \
|
||||
--from-literal=rpc-endpoint="wss://..." \
|
||||
--from-literal=api-key="..."
|
||||
```
|
||||
|
||||
### Process Security
|
||||
```bash
|
||||
# Run as non-root user
|
||||
useradd -r -s /bin/false mevbot
|
||||
chown -R mevbot:mevbot /app
|
||||
sudo -u mevbot ./mev-bot start
|
||||
```
|
||||
|
||||
## Monitoring and Alerting
|
||||
|
||||
### Health Checks
|
||||
```bash
|
||||
# Simple health check
|
||||
curl http://localhost:8080/health
|
||||
|
||||
# Detailed metrics
|
||||
curl http://localhost:9090/metrics | grep mev_bot
|
||||
```
|
||||
|
||||
### Alert Rules
|
||||
```yaml
|
||||
# alertmanager.yml
|
||||
groups:
|
||||
- name: mev-bot-alerts
|
||||
rules:
|
||||
- alert: HighErrorRate
|
||||
expr: mev_bot_error_rate > 0.05
|
||||
for: 5m
|
||||
labels:
|
||||
severity: critical
|
||||
annotations:
|
||||
summary: "MEV Bot error rate is high"
|
||||
|
||||
- alert: L2MessageLag
|
||||
expr: mev_bot_l2_message_lag_ms > 1000
|
||||
for: 2m
|
||||
labels:
|
||||
severity: critical
|
||||
annotations:
|
||||
summary: "L2 message processing lag detected"
|
||||
|
||||
- alert: LowProfitability
|
||||
expr: mev_bot_net_profit_eth < 0
|
||||
for: 10m
|
||||
labels:
|
||||
severity: warning
|
||||
annotations:
|
||||
summary: "Bot is losing money"
|
||||
```
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Common Issues
|
||||
|
||||
#### L2 Message Subscription Failures
|
||||
```bash
|
||||
# Check WebSocket connectivity
|
||||
wscat -c wss://arb-mainnet.g.alchemy.com/v2/YOUR_KEY
|
||||
|
||||
# Verify endpoints
|
||||
curl -X POST -H "Content-Type: application/json" \
|
||||
--data '{"jsonrpc":"2.0","method":"eth_chainId","params":[],"id":1}' \
|
||||
https://arb-mainnet.g.alchemy.com/v2/YOUR_KEY
|
||||
```
|
||||
|
||||
#### High Memory Usage
|
||||
```bash
|
||||
# Monitor memory
|
||||
htop
|
||||
# Check for memory leaks
|
||||
pprof http://localhost:9090/debug/pprof/heap
|
||||
```
|
||||
|
||||
#### Rate Limiting Issues
|
||||
```bash
|
||||
# Check rate limit status
|
||||
grep "rate limit" /var/log/mev-bot/mev-bot.log
|
||||
# Adjust rate limits in config
|
||||
```
|
||||
|
||||
### Logs Analysis
|
||||
```bash
|
||||
# Real-time log monitoring
|
||||
tail -f /var/log/mev-bot/mev-bot.log | grep "L2 message"
|
||||
|
||||
# Error analysis
|
||||
grep "ERROR" /var/log/mev-bot/mev-bot.log | tail -20
|
||||
|
||||
# Performance metrics
|
||||
grep "processing_latency" /var/log/mev-bot/mev-bot.log
|
||||
```
|
||||
|
||||
## Backup and Recovery
|
||||
|
||||
### Data Backup
|
||||
```bash
|
||||
# Backup database
|
||||
cp /data/mev-bot-production.db /backup/mev-bot-$(date +%Y%m%d).db
|
||||
|
||||
# Backup configuration
|
||||
tar -czf /backup/mev-bot-config-$(date +%Y%m%d).tar.gz config/
|
||||
```
|
||||
|
||||
### Disaster Recovery
|
||||
```bash
|
||||
# Quick recovery
|
||||
systemctl stop mev-bot
|
||||
cp /backup/mev-bot-YYYYMMDD.db /data/mev-bot-production.db
|
||||
systemctl start mev-bot
|
||||
```
|
||||
|
||||
