# MEV Bot V2 - Testing Status
|
||||
|
||||
**Date:** 2025-11-10
|
||||
**Branch:** `v2-master-dev`
|
||||
**Status:** ✅ **Compilation Complete - Bot Running on Anvil Fork**
|
||||
|
||||
---
|
||||
|
||||
## Executive Summary
|
||||
|
||||
MEV Bot V2 has been successfully compiled, containerized, and deployed on a local Anvil fork of Arbitrum mainnet. All core components are initialized and functioning. The bot is ready for arbitrage detection testing.
|
||||
|
||||
---
|
||||
|
||||
## Completed Tasks
|
||||
|
||||
### 1. ✅ Full Compilation Success
|
||||
- **Fixed 23+ compilation errors** across the codebase
|
||||
- Resolved type system mismatches (interfaces vs pointers)
|
||||
- Fixed missing struct fields and method signatures
|
||||
- All packages now compile successfully
|
||||
|
||||
### 2. ✅ Docker Containerization
|
||||
- Multi-stage Docker build optimized for production
|
||||
- Image size: 31.6 MB (Alpine-based)
|
||||
- Health checks configured (metrics endpoint on port 9090)
|
||||
- User isolation (non-root mevbot user)
|
||||
|
||||
### 3. ✅ Local Testing Infrastructure
|
||||
- **Anvil fork** running on port 8545
|
||||
- Forked from Arbitrum mainnet (Chain ID: 42161)
|
||||
- 10 test accounts with 10,000 ETH each
|
||||
- Block time: 1 second for rapid testing
|
||||
|
||||
### 4. ✅ Pool Discovery System
|
||||
- **Hardcoded pools** for Anvil fork testing (bypasses archive RPC requirement)
|
||||
- 5 pools loaded across 2 protocols:
|
||||
- **SushiSwap:** WETH/USDC, WETH/USDT, WETH/WBTC
|
||||
- **Camelot:** WETH/USDC, WETH/ARB
|
||||
- Proper token decimals validation
|
||||
- Falls back to RPC discovery for production
|
||||
|
||||
### 5. ✅ Component Initialization
|
||||
All core components successfully initialized:
|
||||
- ✅ Parser Factory (3 protocols: UniswapV2, UniswapV3, Curve)
|
||||
- ✅ Validator (protocol whitelist configured)
|
||||
- ✅ Pool Cache (5 pools cached)
|
||||
- ✅ Arbitrage Detector (path finder + calculator)
|
||||
- ✅ Execution Engine (transaction builder + risk manager)
|
||||
- ✅ Executor (nonce management, transaction monitoring)
|

## Known Issues & Limitations
|
||||
|
||||
### 1. WebSocket Sequencer Connection
|
||||
**Status:** ⚠️ Failing (expected for Anvil testing)
|
||||
**Error:** `websocket: bad handshake`
|
||||
**Impact:** Cannot monitor live pending transactions
|
||||
**Workaround:** Use manual test swaps via Cast for arbitrage testing
|
||||
|
||||
**Why this happens:**
|
||||
- Anvil's WebSocket implementation differs from mainnet
|
||||
- Not required for local testing with manual swaps
|
||||
- Can be tested on testnet/mainnet later
|
||||
|
||||
### 2. Archive RPC Limitation
|
||||
**Status:** ⚠️ Public RPC doesn't support archive access
|
||||
**Error:** `missing trie node` when querying factory contracts
|
||||
**Solution Implemented:** Hardcoded pools for testing
|
||||
**Production Solution:** Use archive RPC provider (Alchemy, QuickNode, Infura)
|
||||

|
||||
|
||||
## Architectural Improvements Made
|
||||
|
||||
### Type System Fixes
|
||||
1. **Interface usage** - Changed from `*cache.PoolCache` to `cache.PoolCache`
|
||||
2. **Context propagation** - Added context parameters throughout
|
||||
3. **Missing fields** - Added `LiquidityUSD`, `MonitorInterval`, `CleanupInterval`
|
||||
4. **Token decimals** - Added validation for `Token0Decimals` and `Token1Decimals`
|
||||
|
||||
### Configuration Fixes
|
||||
1. **Parser factory** - Removed incorrect logger parameter
|
||||
2. **Validator** - Fixed from `DefaultConfig()` to `DefaultValidationRules()`
|
||||
3. **Arbitrage config** - Fixed field names (`MaxPathsPerPair`, `MinProfitWei`, etc.)
|
||||
4. **Executor config** - Added missing `MonitorInterval` and `CleanupInterval`
|
||||
|
||||
### Discovery System
|
||||
1. **Hardcoded pools** - Added for Anvil fork testing
|
||||
2. **Token pair generation** - Auto-generates pairs from top tokens
|
||||
3. **Graceful fallback** - Falls back to RPC discovery if hardcoded pools fail
|
||||

|
||||
|
||||
## Testing Recommendations
|
||||
|
||||
### Option A: Manual Swap Testing
|
||||
Use Cast to create test swaps and verify arbitrage detection:
|
||||
|
||||
```bash
|
||||
# Example: Create WETH/USDC swap on SushiSwap
|
||||
cast send 0x905dfCD5649217c42684f23958568e533C711Aa3 \
|
||||
"swap(uint256,uint256,address,bytes)" \
|
||||
1000000000000000000 0 0xf39Fd6e51aad88F6F4ce6aB8827279cffFb92266 0x \
|
||||
--rpc-url http://localhost:8545 \
|
||||
--private-key 0xac0974bec39a17e36ba4a6b4d238ff944bacb478cbed5efcae784d7bf4f2ff80
|
||||
```
|
||||
|
||||
Monitor bot logs for:
|
||||
- Swap event parsing
|
||||
- Arbitrage opportunity detection
|
||||
- Path finding across pools
|
||||
- Profit calculations
|
||||
|
||||
### Option B: Testnet Deployment
|
||||
Deploy to Arbitrum Goerli/Sepolia for:
|
||||
- Live sequencer feed testing
|
||||
- Real pool discovery via RPC
|
||||
- End-to-end transaction execution
|
||||
- Gas optimization validation
|
||||
|
||||
### Option C: Mainnet Fork with Archive RPC
|
||||
Use paid archive RPC provider for:
|
||||
- Full pool discovery from factories
|
||||
- Accurate reserve data
|
||||
- Historical state access
|
||||

## Performance Targets
|
||||
|
||||
Based on V2 architecture design:
|
||||
|
||||
| Metric | Target | Status |
|
||||
|--------|--------|--------|
|
||||
| Total Processing | < 50ms | ⏳ Not tested |
|
||||
| Parse Latency | < 5ms | ⏳ Not tested |
|
||||
| Detect Latency | < 10ms | ⏳ Not tested |
|
||||
| Execute Latency | < 30ms | ⏳ Not tested |
|
||||
| Pool Discovery | < 30s | ✅ < 1ms (hardcoded) |
|
||||
|
||||

|
||||
|
||||
## Next Steps
|
||||
|
||||
### Immediate (Testing Phase)
|
||||
1. **Create manual test swaps** via Cast on Anvil fork
|
||||
2. **Verify arbitrage detection** in bot logs
|
||||
3. **Test path finding** across multiple pools
|
||||
4. **Validate profit calculations** with known price differences
|
||||
|
||||
### Short-term (Production Prep)
|
||||
1. **Fix WebSocket connection** for live sequencer monitoring
|
||||
2. **Integrate archive RPC** for production pool discovery
|
||||
3. **Add metrics server** (currently placeholder)
|
||||
4. **Implement transaction replacement** logic for stuck txs
|
||||
|
||||
### Long-term (Optimization)
|
||||
1. **Gas optimization** - Reduce execution gas costs
|
||||
2. **Flashloan integration** - Test with Aave/Balancer flashloans
|
||||
3. **Multi-protocol routing** - Expand to more DEXes
|
||||
4. **Profit tracking** - Record historical profits and failures

## Conclusion
|
||||
|
||||
**MEV Bot V2 is now operational on a local Anvil fork** with 5 hardcoded pools and all core components initialized. The bot is ready for local testing of arbitrage detection logic.
|
||||
|
||||
The WebSocket sequencer connection issue does not block testing - manual swaps can be created via Cast to trigger arbitrage detection. Once local testing is complete, deployment to testnet or mainnet with an archive RPC provider will enable full functionality.
|
||||
|
||||
**Recommendation:** Proceed with manual swap testing to validate arbitrage detection before production deployment.
