🎓 Quick Start

See QUICKSTART.md for detailed instructions. Summary:

# 1. Start Anvil fork
anvil --fork-url https://arb1.arbitrum.io/rpc \
      --chain-id 42161 --port 8545

# 2. Build and run bot
docker build -t mev-bot-v2 .
docker run --rm --network host --env-file .env \
  -e RPC_URL=http://localhost:8545 \
  -e WS_URL=ws://localhost:8545 \
  mev-bot-v2

# 3. Create test swap (in another terminal)
cast send <ROUTER> "swapExactTokensForTokens(...)" \
  --private-key <KEY> --rpc-url http://localhost:8545

# 4. Monitor metrics
curl http://localhost:9090/metrics

• ✅ Circuit breakers for cascading failures
• ✅ Transaction simulation before execution
• ✅ Input validation at all layers
• ✅ Graceful error handling

To Review

• ⏳ Audit all transaction signing code

💰 Profitability Estimates

Based on planning documents:

Conservative Scenario:

• 20-50 trades/day
• 0.01-0.02 ETH profit/trade
• 70-80% success rate
• Expected: 8.4-21 ETH/month

Optimistic Scenario:

• 100-200 trades/day
• 0.03-0.05 ETH profit/trade
• 80-85% success rate
• Expected: 127-255 ETH/month

Note: Actual profitability depends on:

• Market conditions
• Competition (other MEV bots)
• Gas prices
• Network latency
• Parameter tuning
