# MEV Bot Production Remediation - Comprehensive Action Plan
|
||||
|
||||
**Date:** November 6, 2025
|
||||
**Status:** IN EXECUTION - Critical Issues Identified and Fixing
|
||||
**Priority:** CRITICAL - Multiple blockers to production deployment
|
||||
|
||||
---
|
||||
|
||||
## EXECUTIVE SUMMARY
|
||||
|
||||
**Current State:**
|
||||
- ✅ Format string compile error FIXED
|
||||
- ⚠️ Tests EXIST (71 files) and RUN but have FAILURES
|
||||
- ❌ CRITICAL packages missing tests (profitcalc, exchanges, tokens, etc.)
|
||||
- ❌ Test coverage and profitability validation PENDING
|
||||
- ⏳ Full bot execution and validation NOT YET DONE
|
||||
|
||||
**Decision:** **DO NOT DEPLOY UNTIL:**
|
||||
1. All failing tests fixed ✅
|
||||
2. Missing tests created for critical packages ✅
|
||||
3. Code coverage ≥ 80% minimum ✅
|
||||
4. Bot execution validates opportunity detection ✅
|
||||
|
||||
---
|
||||
|
||||
## CRITICAL FINDINGS
|
||||
|
||||
### 1. FORMAT STRING ERROR ✅ RESOLVED
|
||||
- **File:** `pkg/profitcalc/profit_calc.go:277`
|
||||
- **Issue:** `(> 1000%)` should be `(> 1000%%)`
|
||||
- **Status:** FIXED - Build now succeeds
|
||||
- **Action:** COMPLETED
|
||||
|
||||
### 2. TEST FAILURES DETECTED 🔴 REQUIRES IMMEDIATE FIX
|
||||
**Failing Tests in pkg/arbitrage:**
|
||||
```
|
||||
FAIL: TestNewMultiHopScanner
|
||||
- Expected 4 paths, got 3
|
||||
- Expected amount 1000000000000000, got 10000000000000
|
||||
- Expected 0.03 fee, got 0.05
|
||||
- Expected 100 confidence, got 200
|
||||
- Expected 500ms timeout, got 2s
|
||||
|
||||
FAIL: TestEstimateHopGasCost
|
||||
- Expected 150000 gas for hop 1, got 70000
|
||||
- Expected 120000 gas for hop 2, got 60000
|
||||
- Expected 120000 gas for hop 3, got 60000
|
||||
```
|
||||
**Action:** Must fix these test assertions or correct the implementation
|
||||
|
||||
### 3. MISSING CRITICAL TEST FILES 🔴 HIGH PRIORITY
|
||||
Packages WITH code but NO tests:
|
||||
- `pkg/profitcalc` (CRITICAL - profit calculations!)
|
||||
- `pkg/exchanges` (DEX interactions)
|
||||
- `pkg/tokens` (token handling)
|
||||
- `pkg/execution` (trade execution)
|
||||
- `pkg/trading`
|
||||
- `pkg/oracle`
|
||||
- `pkg/performance`
|
||||
- `pkg/patterns`
|
||||
- `pkg/dex`
|
||||
- And 10+ more packages
|
||||
|
||||
**Action:** Must create tests for all critical packages
|
||||
|
||||
### 4. ZERO CODE COVERAGE ISSUE 🟡 INVESTIGATION COMPLETE
|
||||
- **Issue:** Earlier runs showed 0.0% coverage despite tests existing
|
||||
- **Root Cause:** Output buffering and tee issues (not a real problem)
|
||||
- **Resolution:** Actual tests ARE running and show coverage
|
||||
- **Status:** In progress - full test run underway
|
||||
|
||||
---
|
||||
|
||||
## IMMEDIATE ACTION PLAN (NEXT 24 HOURS)
|
||||
|
||||
### Phase 1: Analyze Full Test Results (NOW - 30 min)
|
||||
**When full test run completes:**
|
||||
```bash
|
||||
# Check total test status
|
||||
go tool cover -func=coverage-full.out | tail -5
|
||||
|
||||
# List all failing tests
|
||||
grep "FAIL:" full-test-results.log | sort | uniq
|
||||
|
||||
# Get coverage summary
|
||||
grep "coverage:" full-test-results.log | sort | uniq -c
|
||||
```
|
||||
|
||||
**Expected Outcome:** Clear list of failures and coverage percentage
|
||||
|
||||
### Phase 2: Fix Failing Tests (1-2 hours)
|
||||
**For TestNewMultiHopScanner failures:**
|
||||
1. Review test assertions in `pkg/arbitrage/multihop_test.go:60-64`
|
||||
2. Verify if test expectations are wrong OR implementation is wrong
|
||||
3. Either fix test or fix implementation
|
||||
4. Re-run tests to verify pass
|
||||
|
||||
**For TestEstimateHopGasCost failures:**
|
||||
1. Review gas estimation logic in `pkg/arbitrage/multihop.go`
|
||||
2. Check if hardcoded gas values match actual costs
|
||||
3. Fix either test or implementation
|
||||
4. Re-run and verify
|
||||
|
||||
### Phase 3: Create Missing Tests for Critical Packages (4-8 hours)
|
||||
|
||||
**Priority 1 (MUST HAVE):**
|
||||
- [ ] `pkg/profitcalc/*_test.go` - Profit calculation tests
|
||||
- [ ] `pkg/execution/*_test.go` - Trade execution tests
|
||||
- [ ] `pkg/exchanges/*_test.go` - DEX interaction tests
|
||||
|
||||
**Priority 2 (SHOULD HAVE):**
|
||||
- [ ] `pkg/tokens/*_test.go` - Token handling tests
|
||||
- [ ] `pkg/trading/*_test.go` - Trading logic tests
|
||||
- [ ] `pkg/oracle/*_test.go` - Price oracle tests
|
||||
|
||||
**Priority 3 (NICE TO HAVE):**
|
||||
- [ ] `pkg/dex/*_test.go` - DEX adapter tests
|
||||
- [ ] `pkg/performance/*_test.go` - Performance tracking tests
|
||||
- [ ] `pkg/patterns/*_test.go` - Pattern matching tests
|
||||
|
||||
### Phase 4: Verify Test Coverage (30 min)
|
||||
```bash
|
||||
# Generate coverage report
|
||||
go test -v -coverprofile=coverage-final.out ./pkg/... ./internal/...
|
||||
go tool cover -func=coverage-final.out | tail -1
|
||||
|
||||
# Target: ≥ 80% coverage
|
||||
# Current: TBD (waiting for full test results)
|
||||
```
|
||||
|
||||
### Phase 5: Validate Profitability Configuration (1 hour)
|
||||
**Review and validate:**
|
||||
```go
|
||||
// File: pkg/profitcalc/profit_calc.go
|
||||
minProfitThreshold = 0.001 ETH // ← May be too high!
|
||||
maxSlippage = 3% (0.03)
|
||||
gasLimit = 100,000
|
||||
gasPrice = 0.1 gwei + dynamic
|
||||
```
|
||||
|
||||
**Actions:**
|
||||
1. Check if 0.001 ETH threshold is realistic for Arbitrum
|
||||
2. Verify gas estimation is accurate
|
||||
3. Test with mock market data to validate profitability detection
|
||||
|
||||
### Phase 6: Run Bot and Validate Execution (1-2 hours)
|
||||
```bash
|
||||
# Build release binary
|
||||
make build
|
||||
|
||||
# Run with full logging
|
||||
LOG_LEVEL=debug METRICS_ENABLED=true timeout 300 ./bin/mev-bot start
|
||||
|
||||
# Check logs for:
|
||||
# - Opportunity detections (should see > 0)
|
||||
# - Successful executions
|
||||
# - Error rates (should be low)
|
||||
# - Performance metrics
|
||||
```
|
||||
|
||||

|
||||
|
||||
## DETAILED FIX CHECKLIST
|
||||
|
||||
### Section A: TEST FAILURES
|
||||
|
||||
#### A1. Fix TestNewMultiHopScanner
|
||||
**Location:** `pkg/arbitrage/multihop_test.go:60-64`
|
||||
```
|
||||
❌ FAIL: expected 4, actual 3
|
||||
❌ FAIL: expected "1000000000000000", actual "10000000000000"
|
||||
❌ FAIL: expected 0.03, actual 0.05
|
||||
❌ FAIL: expected 100, actual 200
|
||||
❌ FAIL: expected 500ms, actual 2s
|
||||
```
|
||||
|
||||
**Investigation needed:**
|
||||
1. Is test data outdated?
|
||||
2. Did implementation change?
|
||||
3. Is there a legitimate calculation difference?
|
||||
|
||||
**Options:**
|
||||
- [ ] Update test expectations if implementation is correct
|
||||
- [ ] Fix implementation if test expectations are correct
|
||||
- [ ] Review git history to understand change
|
||||
|
||||
#### A2. Fix TestEstimateHopGasCost
|
||||
**Location:** `pkg/arbitrage/multihop_test.go:252-264`
|
||||
```
|
||||
❌ FAIL: expected 150000, actual 70000 (hop 1)
|
||||
❌ FAIL: expected 120000, actual 60000 (hop 2)
|
||||
❌ FAIL: expected 120000, actual 60000 (hop 3)
|
||||
```
|
||||
|
||||
**Investigation needed:**
|
||||
1. Are gas estimations too low?
|
||||
2. Are test expectations outdated from earlier audits?
|
||||
3. Is Arbitrum gas model different from expected?
|
||||
|
||||
**Actions:**
|
||||
- [ ] Verify Arbitrum L2 gas prices vs assumptions
|
||||
- [ ] Check if gas can be estimated more accurately
|
||||
- [ ] Update test or implementation
|
||||
|
||||
### Section B: MISSING TESTS
|
||||
|
||||
#### B1. Create profitcalc_test.go (CRITICAL)
|
||||
```go
|
||||
// pkg/profitcalc/profitcalc_test.go
|
||||
// Test coverage needed for:
|
||||
// - ProfitCalculator initialization
|
||||
// - CalculateOpportunity function
|
||||
// - Profit margin calculations
|
||||
// - Slippage validation
|

// Test coverage needed for:
|
||||
// - DEX adapter initialization
|
||||
// - Price fetch operations
|
||||
// - Liquidity pool interactions
|
||||
// - Fee calculations
|
||||
```
|
||||
|
||||
#### B3. Create execution_test.go (CRITICAL)
|
||||
```go
|
||||
// pkg/execution/execution_test.go
|
||||
// Test coverage needed for:
|
||||
// - Transaction building
|
||||
// - Execution strategy selection
|
||||
// - Flash loan integration
|
||||
// - Success/failure handling
|
||||
```
|
||||
|
||||
#### B4. Create tokens_test.go (HIGH)
|
||||
```go
|
||||
// pkg/tokens/tokens_test.go
|
||||
// Test coverage needed for:
|
||||
// - Token metadata caching
|
||||
// - Decimal handling
|
||||
// - Symbol/address resolution
|
||||
```
|
||||
|
||||
### Section C: PROFITABILITY VALIDATION
|
||||
|
||||
#### C1. Verify Min Profit Threshold
|
||||
**Current:** 0.001 ETH = $2.00 at $2000/ETH
|
||||
**Question:** Is this realistic for MEV opportunities?
|
||||
|
||||
**Steps:**
|
||||
1. Research typical Arbitrum arbitrage spreads
|
||||
2. Check if threshold filters out viable trades
|
||||
3. Consider lowering to 0.0001 ETH if needed
|
||||
|
||||
#### C2. Verify Gas Estimation
|
||||
**Current:** Hardcoded 100k gas limit
|
||||
**Question:** Accurate for all transaction types?
|
||||
|
||||
**Steps:**
|
||||
1. Test with real Arbitrum transactions
|
||||
2. Verify actual gas costs vs estimated
|
||||
3. Implement adaptive gas estimation if needed
|
||||
|
||||
#### C3. Validate against market data
|
||||
1. Test profit calculation with real price feeds
|
||||
2. Verify slippage protection
|
||||
3. Check flash loan handling
|
||||
|
||||
### Section D: MAKEFILE OPTIMIZATION FOR PODMAN
|
||||
|
||||
#### D1. Audit Makefile targets
|
||||
```bash
|
||||
# Check which commands use Docker vs Podman
|
||||
grep -r "docker\|Docker" Makefile
|
||||
grep -r "podman\|Podman" Makefile
|
||||
|
||||
# Expected: All commands should be Podman-first
|
||||
```
|
||||
|
||||
#### D2. Update commands
|
||||
- [ ] Build targets - use Podman
|
||||
- [ ] Test targets - use Podman Compose
|
||||
- [ ] CI targets - use Podman
|
||||
- [ ] Deploy targets - use Podman
|
||||

### HIGH RISK: Test failures persist
|
||||
**Mitigation:** Review git history, understand why tests fail, fix root cause
|
||||
|
||||
### MEDIUM RISK: Coverage stays below 80%
|
||||
**Mitigation:** Prioritize critical packages, implement coverage-driven testing
|
||||
|
||||

1. **WAIT:** For full test run to complete (currently running - bash ddf0fe)
|
||||
2. **ANALYZE:** Check full test results and coverage report
|
||||
3. **PRIORITIZE:** List failures by severity
|
||||
4. **FIX:** Address high-severity failures first
|
||||
5. **ITERATE:** Run tests after each fix, verify progress
|
||||
6. **VALIDATE:** Ensure 80%+ coverage before moving to Phase 5
|
||||
|
||||
---
|
||||
|
||||
## DECISION FRAMEWORK
|
||||
|
||||
**If coverage < 50% after fixes:**
|

|
||||
→ Targeted testing for uncovered packages (2-4 hours)
|
||||
|
||||
**If coverage > 80% after fixes:**
|
||||
→ Proceed to profitability validation and bot testing (2-3 hours)
