# MEV Bot Production Readiness - Session Summary
|
|
**Date**: November 3, 2025
|
|
**Status**: 60% Production Ready
|
|
**Blockers**: 4 identified and documented
|
|
|
|
---
|
|
|
|
## 🎯 Mission Accomplished
|
|
|
|
### Primary Goal: Bring MEV Bot to Production Grade
|
|
✅ **PARTIALLY ACHIEVED** - Architecture is production-grade, but 4 critical blockers identified and documented for fixing.
|
|
|
|
---
|
|
|
|
## ✅ Completed Work
|
|
|
|
### 1. **Security Audit Remediation**
|
|
Applied fixes from `reports/security_audit_20251103.md`:
|
|
|
|
| Finding | Status | Action |
|
|
|---------|--------|--------|
|
|
| C-01: Hardcoded RPC Credentials | ✅ FIXED | Removed all hardcoded endpoints |
|
|
| C-02: Exposed Alchemy API Key | ✅ FIXED | Removed from scripts |
|
|
| C-03: Placeholder Authentication | ✅ FIXED | Removed stub auth methods |
|
|
| C-04: Weak Keystore (LightScryptN) | ⏳ IDENTIFIED | Need StandardScryptN for prod |
|
|
| C-05: Unsafe Flash Executor | ✅ FIXED | Using FlashLoanReceiverSecure |
|
|
| C-06: Non-Compilable Contract | ✅ FIXED | Added AccessControlEnumerable import |
|
|
|
|
### 2. **Contract Repository Organization**
|
|
```
|
|
BEFORE: Mixed Solidity + Go code
|
|
/home/administrator/projects/mev-beta/contracts/
|
|
|
|
AFTER: Dedicated Foundry project
|
|
/home/administrator/projects/Mev-Alpha/
|
|
├── contracts/
|
|
│ ├── ProductionArbitrageExecutor.sol ✅ (C-06 fixed)
|
|
│ ├── PoolDetector.sol
|
|
│ ├── DataFetcher.sol (new standalone version)
|
|
│ └── balancer/
|
|
├── foundry.toml
|
|
├── lib/ (dependencies)
|
|
└── out/ (compiled artifacts)
|
|
```
|
|
|
|
### 3. **Infrastructure Setup**
|
|
- **Anvil Fork**: ✅ Running on http://127.0.0.1:8545
|
|
- **Network**: ✅ Forked from Arbitrum mainnet (Chain ID: 42161)
|
|
- **Test Account**: ✅ 0xf39Fd6e51aad88F6F4ce6aB8827279cfffb92266
|
|
- **Buildable**: ✅ Mev-Alpha contracts compile successfully
|
|
|
|
### 4. **Root Cause Analysis**
|
|
|
|
#### **BLOCKER #1: Invalid Pool Addresses (75% of blacklist)**
|
|
```
|
|
Symptom: Error getting pool data for 0xC6962004f452bE9203591991D15f6b388e09E8D0
|
|
Analysis:
|
|
- 684 total blacklisted pools
|
|
- 513 (75%) have NO contract deployed (no bytecode)
|
|
- 171 (25%) are valid contracts mostly working
|
|
|
|
Root Cause: Addresses extracted from wrong positions in swap logs
|
|
Location: pkg/scanner/swap/analyzer.go:161 (GetPoolData call)
|
|
|
|
Solution: Check contract existence BEFORE querying
|
|
```
|
|
|
|
#### **BLOCKER #2: Multi-Hop Scanner Finding 0 Paths**
|
|
```
|
|
Symptom: "found 0 profitable paths out of 0 total paths"
|
|
Analysis:
|
|
- DFS algorithm working correctly
|
|
- createArbitragePath returning nil for all paths
|
|
- calculateSwapOutput failing due to placeholder data
|
|
|
|
Root Cause: Hardcoded 1 ETH placeholder for all pool reserves
|
|
Location: pkg/arbitrage/multihop.go:485 (uint256.NewInt(1000000000000000000))
|
|
|
|
Solution: Fetch real pool reserves before profit calculations
|
|
```
|
|
|
|
#### **BLOCKER #3: Security Manager Disabled**
|
|
```
|
|
Status: Not initialized during startup
|
|
Location: cmd/mev-bot/main.go:141 (commented out)
|
|
|
|
Impact: No transaction validation, no audit logging
|
|
Solution: Re-enable and test with proper configuration
|
|
```
|
|
|
|
#### **BLOCKER #4: Zero Arbitrage Executions**
|
|
```
|
|
Current Log:
|
|
"Detected: 0, Executed: 0, Successful: 0, Success Rate: 0.00%"
|
|
|
|
Root Cause: Cascading failure from Blockers #1-3
|
|
Solution: Fix above issues in sequence
|
|
```
|
|

## 📊 System Health
|
|
|
|
### ✅ Working Components
|
|
- ✅ Event-driven transaction parsing (~90% success rate)
|
|
- ✅ Real-time Arbitrum block monitoring (sub-second latency)
|
|
- ✅ Multi-DEX protocol support (Uniswap V2/V3, SushiSwap, Curve, Balancer, Algebra)
|
|
- ✅ Production logging system (health score: 97.97/100)
|
|
- ✅ RPC failover and rate limiting (6-provider multi-fallback)
|
|
- ✅ Transaction pipeline (handles 50,000+ tx buffer)
|
|
|
|
### ⏳ Partially Working
|
|
- ⏳ Pool discovery (caches 314 pools, background task disabled)
|
|
- ⏳ KeyManager (works independently, security manager commented out)
|
|
|
|
### ❌ Not Working
|
|
- ❌ Multi-hop arbitrage scanner (0 paths found)
|
|
- ❌ Pool data fetching (invalid address validation missing)
|
|
- ❌ Arbitrage execution (no opportunities to execute)
|
|

## 🔧 Next Steps (Priority Order)
|
|
|
|
### Immediate Actions (Next Session)
|
|
1. **Implement pool validation** (HIGH IMPACT)
|
|
- Add contract existence check: `if extcodesize(pool) == 0, skip`
|
|
- Location: `pkg/scanner/swap/analyzer.go:161`
|
|
- Est. time: 30 minutes
|
|
|
|
2. **Replace placeholder liquidity** (HIGH IMPACT)
|
|
- Fetch actual reserves from pool contracts
|
|
- Location: `pkg/arbitrage/multihop.go:238-260`
|
|
- Est. time: 1-2 hours
|
|
|
|
3. **Test multi-hop scanner** (VALIDATION)
|
|
- Deploy on Anvil fork
|
|
- Test with known Uniswap V3 pools
|
|
- Est. time: 1 hour
|
|
|
|
4. **Re-enable security manager** (SAFETY)
|
|
- Uncomment in main.go:141
|
|
- Test with safe mode
|
|
- Est. time: 30 minutes
|
|
|
|
### Short-term (Production Path)
|
|
1. Clear invalid pools from blacklist (`logs/pool_blacklist.json`)
|
|
2. Deploy contracts on Anvil fork
|
|
3. End-to-end pipeline testing
|
|
4. Set up monitoring and alerts
|
|
|
|
### Medium-term (Weeks 2-4)
|
|
1. Production wallet setup with gas management
|
|
2. Execution safety checks validation
|
|
3. Profit calculation verification
|
|
4. Live testing with small capital
|

## 💡 Key Insights
|
|
|
|
### What's Working Well
|
|
1. **Architecture**: Modular, testable, production-grade design
|
|
2. **Monitoring**: Advanced logging system with health scoring
|
|
3. **RPC Management**: Intelligent failover with 6 providers
|
|
4. **Event Processing**: High-throughput transaction pipeline
|
|
|
|
### What Needs Immediate Attention
|
|
1. **Pool Validation**: Need strict address validation before RPC calls
|
|
2. **Data Fetching**: Must use real pool data, not placeholders
|
|
3. **Execution Pipeline**: Needs end-to-end testing
|
|
4. **Security**: Needs all components re-enabled and tested
|
|
|
|
### What Can Wait (But Important)
|
|
1. Database persistence (currently in-memory)
|
|
2. MEV protection (Flashbots integration)
|
|
3. Multi-chain support (currently Arbitrum only)
|
|
4. ML-based opportunity prediction
