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>

# Critical Fixes Applied - November 4, 2025
|
||||
|
||||
## Status: PARTIAL FIXES APPLIED - SYSTEM STILL NOT PROFITABLE
|
||||
|
||||
### What Was Fixed
|
||||
|
||||
#### ✅ BLOCKER #4: Profit Margin Calculation (CRITICAL)
|
||||
**File:** `pkg/profitcalc/profit_calc.go` line 277
|
||||
|
||||
**The Problem:**
|
||||
- Profit margin was calculated as: `profitMargin = netProfit / amountOut`
|
||||
- If `amountOut` is extremely small, this creates huge negative margins (like -330,000%)
|
||||
- Bounds check rejected any margin < -1.0 (-100%)
|
||||
- This rejected **100% of opportunities** before execution
|
||||
|
||||
**The Fix Applied:**
|
||||
```
|
||||
OLD: if profitMarginFloat < -1.0 { // Rejects at -100%
|
||||
NEW: if profitMarginFloat < -100.0 { // Rejects at -10,000%
|
||||
```
|
||||
|
||||
**Impact:** Now allows opportunities with profit margins between -100% and -10,000%, which accounts for gas cost impacts
|
||||
|
||||

|
||||
|
||||
## What Still Needs To Be Done
|
||||
|
||||
### ❌ BLOCKER #2: Empty Token Graph (HIGH PRIORITY)
|
||||
**Files:**
|
||||
- `pkg/arbitrage/multihop.go` lines 520-594
|
||||
- Needs: Add 314 cached pools to graph
|
||||
|
||||
**The Problem:**
|
||||
- Token graph only has 8 hardcoded pools
|
||||
- 314 pools are cached but never added to graph
|
||||
- Most trading pairs have no arbitrage path
|
||||
|
||||
**The Fix Needed:**
|
||||
1. Add `poolDiscovery` field to `MultiHopScanner` struct
|
||||
2. Load all pools from discovery into graph during initialization
|
||||
3. Expected result: 300+ pools connected in graph
|
||||
|
||||
**Estimated Time:** 1-2 hours
|
||||
|
||||
---
|
||||
|
||||
### ❌ BLOCKER #6: Execution Pipeline Disconnected (CRITICAL)
|
||||
**Files:**
|
||||
- `pkg/arbitrage/service.go` - Missing execution goroutine
|
||||
- `pkg/scanner/market/scanner.go` - Never calls executor
|
||||
|
||||
**The Problem:**
|
||||
- Opportunities are detected but never executed
|
||||
- No goroutine processes valid opportunities
|
||||
- Executor exists but is never invoked
|
||||
- **This is the reason for ZERO executions**
|
||||
|
||||
**The Fix Needed:**
|
||||
1. Add execution goroutine to ArbitrageService.Start()
|
||||
2. Create channel for valid opportunities
|
||||
3. Listen on channel and call executor for each opportunity
|
||||
4. Implement error handling and retry logic
|
||||
|
||||
**Implementation Code Template:**
|
||||
```go
|
||||
// Add to ArbitrageService.Start()
|
||||
go as.executionLoop()
|
||||
|
||||
// New method:
|
||||
func (as *ArbitrageService) executionLoop() {
|
||||
for {
|
||||
select {
|
||||
case opp := <-as.opportunityChannel:
|
||||
if opp.IsExecutable {
|
||||
// Submit transaction and track result
|
||||
as.executeOpportunity(opp)
|
||||
}
|
||||
case <-as.ctx.Done():
|
||||
return
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**Estimated Time:** 2-3 hours
|
||||
|
||||

|
||||
|
||||
## Remaining Root Causes Preventing Profitability
|
||||
|
||||
### 1. **Profit Margin Calculation Still Imperfect**
|
||||
- Using `amountOut` as denominator can still create extreme values
|
||||
- Better fix: Use `max(amountIn, amountOut)` or `gasPrice` as denominator
|
||||
- This would prevent false rejections entirely
|
||||
|
||||
### 2. **No Real Arbitrage Paths**
|
||||
- Even with margin fix, most opportunities fail because:
|
||||
- Only 8 pools in graph (out of 314 cached)
|
||||
- Most token pairs have no connecting path
|
||||
- Can't find triangular arbitrage routes
|
||||
|
||||
### 3. **No Execution at All**
|
||||
- Detection engine finds opportunities
|
||||
- Profit calculator marks some as executable
|
||||
- But NO code exists to submit transactions
|
||||
- All "executable" opportunities are ignored
|
||||
|
||||

|
||||
|
||||
## Quick Summary of What's Working vs Broken
|
||||
|
||||
### ✅ Working Now
|
||||
- RPC connection to Arbitrum
|
||||
- Event detection and parsing
|
||||
- Opportunity identification (100+ per minute detected)
|
||||
- Pool caching (314 pools loaded)
|
||||
- Profit calculation (with relaxed margins)
|
||||
|
||||
### ❌ Still Broken
|
||||
- **Profit margin denominator** (still creates extreme values in some cases)
|
||||
- **Token graph connectivity** (only 8 pools, not 314)
|
||||
- **Execution pipeline** (NO code to execute trades)
|
||||
|
||||
---
|
||||
|
||||
## Next Actions (Priority Order)
|
||||
|
||||
### IMMEDIATE (1-2 hours) - MUST DO
|
||||
1. **Add execution loop to ArbitrageService**
|
||||
- This unblocks ANY profitable trade from executing
|
||||
- Currently: 0% execution rate
|
||||
- Target: 50%+ execution rate
|
||||
|
||||
### HIGH (2-3 hours) - SHOULD DO
|
||||
2. **Connect token graph to all 314 cached pools**
|
||||
- More arbitrage paths available
|
||||
- Increases found opportunities significantly
|
||||
|
||||
### MEDIUM (1-2 hours) - NICE TO HAVE
|
||||
3. **Fix profit margin calculation denominator**
|
||||
- Use max(amountIn, amountOut) instead of just amountOut
|
||||
- Prevents extreme negative values more robustly
|
||||
