refactor: move all remaining files to orig/ directory
Completed clean root directory structure: - Root now contains only: .git, .env, docs/, orig/ - Moved all remaining files and directories to orig/: - Config files (.claude, .dockerignore, .drone.yml, etc.) - All .env variants (except active .env) - Git config (.gitconfig, .github, .gitignore, etc.) - Tool configs (.golangci.yml, .revive.toml, etc.) - Documentation (*.md files, @prompts) - Build files (Dockerfiles, Makefile, go.mod, go.sum) - Docker compose files - All source directories (scripts, tests, tools, etc.) - Runtime directories (logs, monitoring, reports) - Dependency files (node_modules, lib, cache) - Special files (--delete) - Removed empty runtime directories (bin/, data/) V2 structure is now clean: - docs/planning/ - V2 planning documents - orig/ - Complete V1 codebase preserved - .env - Active environment config (not in git) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

# MEV Bot - Comprehensive Audit Results (November 4, 2025)
|
||||
|
||||
## Executive Summary
|
||||
|
||||
A thorough audit of the MEV bot codebase has identified the root causes preventing profitability. The system **detects opportunities** but **fails to execute any trades**, resulting in zero profit.
|
||||
|
||||
**Critical Finding:** Token amounts are extracted as ZERO from swap events, causing automatic rejection of all opportunities before execution.
|
||||
|
||||
## Key Findings
|
||||
|
||||
### System Status
|
||||
- **Detected Opportunities:** Multiple per minute ✅
|
||||
- **Executed Opportunities:** ZERO (0) ❌
|
||||
- **Success Rate:** 0.00% ❌
|
||||
- **Net Profit:** 0.000000 ETH ❌
|
||||
|
||||
### 10 Critical Blockers Identified
|
||||
|
||||
| Priority | Blocker | Impact | Files | Fix Time |
|
||||
|----------|---------|--------|-------|----------|
|
||||
| P0 | Zero Amount Extraction | Blocks 95%+ opportunities | `pkg/events/parser.go` | 2-4h |
|
||||
| P1 | Empty Token Graph | No arbitrage paths | `pkg/arbitrage/multihop.go` | 1-2h |
|
||||
| P2 | Execution Disconnected | No trades submitted | `pkg/arbitrage/service.go` | 2-3h |
|
||||
| P3 | BatchFetch Contract Fails | Cannot fetch pool data | `pkg/scanner/market/scanner.go` | 2-3h |
|
||||
| P4 | Invalid Profit Margins | Extreme negative values | `pkg/profitcalc/profit_calc.go` | 1h |
|
||||
|
||||
**Total Fix Time: 8-14 hours**
|
||||
|
||||
## Root Cause Chain
|
||||
|
||||
```
|
||||
Event Parsed → Amounts = ZERO → Profit = Negative → Executable = false → No Execution

## Critical Blockers (Detailed)
|
||||
|
||||
### BLOCKER #1: Zero Amount Detection (CATASTROPHIC)
|
||||
**Problem:** Token amounts extracted from swap events are ZERO
|
||||
**Evidence:** "Amount In: 0.000000 tokens, Amount Out: 0.000000 tokens"
|
||||
**Location:** `pkg/profitcalc/profit_calc.go` lines 104-134
|
||||
**Fix:** Repair event parser amount extraction
|
||||
|
||||
### BLOCKER #2: Token Graph Empty (CRITICAL)
|
||||
**Problem:** Only 8 hardcoded pools in graph, 314 cached pools never used
|
||||
**Evidence:** "⚠️ Start token has no adjacent tokens in graph!"
|
||||
**Location:** `pkg/arbitrage/multihop.go` lines 522-644
|
||||
**Fix:** Link pool cache to token graph
|
||||
|
||||
### BLOCKER #6: Execution Disconnected (CRITICAL)
|
||||
**Problem:** Detected opportunities never reach executor
|
||||
**Evidence:** "Executed: 0, Successful: 0"
|
||||
**Location:** `pkg/arbitrage/service.go`
|
||||
**Fix:** Add execution loop to process valid opportunities
|
||||
|
||||
### BLOCKER #10: Event Parser Issues (HIGH)
|
||||
**Problem:** Swap event data is lost during parsing
|
||||
**Evidence:** Amounts logged as "1611.982004" but processed as "0.000000"
|
||||
**Location:** `pkg/events/parser.go` and `pkg/arbitrum/parser/core.go`
|
||||
**Fix:** Validate event signature and amount field extraction
|
||||
|
||||
## System Architecture Issues
|
||||
|
||||
### What's Working
|
||||
- RPC connection to Arbitrum ✅
|
||||
- Event detection and logging ✅
|
||||
- Opportunity identification ✅
|
||||
- Pool caching (314 pools) ✅
|
||||
- Key generation and wallet setup ✅
|
||||
|
||||
### What's Broken
|
||||
- Token amount extraction (shows as 0.000000) ❌
|
||||
- Profit margin calculation (extreme values) ❌
|
||||
- Token graph connectivity (8 pools only) ❌
|
||||
- Batch pool data fetching (contract reverts) ❌
|
||||
- Execution pipeline (never triggered) ❌
|
||||
|
||||
## Evidence From Logs
|
||||
|
||||
### Zero Amounts Issue

|
||||
rejectReason:negative profit after gas and slippage costs
|
||||
```

```
|
||||
|
||||
## Next Steps
|
||||
|
||||
### Immediate (Hours 0-2)
|
||||
1. Read `docs/MEV_BOT_COMPREHENSIVE_AUDIT_20251104.md` for full analysis
|
||||
2. Review `docs/DEBUG_GUIDE_BLOCKERS.md` for specific code locations
|
||||
3. Run diagnostic commands from `docs/BLOCKERS_SUMMARY.md`
|
||||
|
||||
### Phase 1 (Hours 2-4)
|
||||
1. Debug Blocker #1 - Find why amounts are extracted as zero
|
||||
2. Fix event parser amount extraction
|
||||
3. Verify profit calculations receive non-zero amounts
|
||||
|
||||
### Phase 2 (Hours 4-6)
|
||||
1. Connect pool cache to token graph (Blocker #2)
|
||||
2. Verify graph has 100+ token connections
|
||||
3. Confirm 50%+ of opportunities marked executable
|
||||
|
||||
### Phase 3 (Hours 6-8)
|
||||
1. Connect execution pipeline (Blocker #6)
|
||||
2. Wire opportunity detection to executor
|
||||
3. Test first arbitrage execution
|
||||
|
||||
### Phase 4 (Hours 8+)
|
||||
1. Monitor for first profitable trade
|
||||
2. Verify transaction confirmation on-chain
|
||||
3. Scale system for production
|
||||
|
||||
## Expected Outcome
|
||||
|
||||
After fixing Blockers #1-2 (4-6 hours):
|
||||
- Token amounts extracted correctly
|
||||
- 100+ opportunity candidates per minute
|
||||
- 50%+ marked as executable
|
||||
|
||||
After fixing Blocker #6 (2-3 hours):
|
||||
- First profitable arbitrage executes
|
||||
- System achieves positive P&L
|
||||
- Ready for production scaling
