### Expected Test Flow
```
1. Start Anvil fork (forked from Arbitrum mainnet)

↓
4. Bot connects to WebSocket (sequencer reader)
↓
5. Create test swap on forked chain
↓
6. Bot detects swap in pending transactions
↓
7. Bot parses swap event
↓
8. Bot detects arbitrage opportunity
↓
9. Bot calculates profitability
↓
10. Bot executes front-run transaction (if profitable)

11. Verify execution in logs and metrics
```
### Success Criteria
1. ✅ Bot starts without compilation errors

3. ⏳ WebSocket connected (connected to sequencer)
4. ⏳ Test swaps detected (tx_processed increases)
5. ⏳ Opportunities found (opportunities_found > 0)
6. ⏳ Executions attempted (executions_attempted > 0)
7. ⏳ Metrics accessible (http://localhost:9090/metrics)

```bash
# 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
```

## 💰 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
