|
||||
|
||||
### ⚠️ PENDING (Phase 2 - High Priority)
|
||||
|
||||
#### 1. Critical: Remove Blocking RPC Call
|
||||
**File**: `pkg/sequencer/reader.go:357`
|
||||
|
||||
**Issue**:
|
||||
```go
|
||||
// BLOCKING CALL in hot path - SPEC.md violation
|
||||
tx, isPending, err := r.rpcClient.TransactionByHash(procCtx, common.HexToHash(txHash))
|
||||
```
|
||||
|
||||
**Solution Needed**:
|
||||
The sequencer feed should contain full transaction data. Current architecture:
|
||||
1. SwapFilter decodes transaction from sequencer message
|
||||
2. Passes tx hash to reader
|
||||
3. Reader fetches full transaction via RPC (BLOCKING!)
|
||||
|
||||
**Fix Required**:
|
||||
Change SwapFilter to pass full transaction object instead of hash:
|
||||
```go
|
||||
// Current (wrong):
|
||||
type SwapEvent struct {
|
||||
TxHash string // Just the hash
|
||||
...
|
||||
}
|
||||
|
||||
// Should be:
|
||||
type SwapEvent struct {
|
||||
TxHash string
|
||||
Transaction *types.Transaction // Full TX from sequencer
|
||||
...
|
||||
}
|
||||
```
|
||||
|
||||
Then update reader.go to use the passed transaction directly:
|
||||
```go
|
||||
// Remove this blocking call:
|
||||
// tx, isPending, err := r.rpcClient.TransactionByHash(...)
|
||||
|
||||
// Use instead:
|
||||
tx := swapEvent.Transaction
|
||||
```
|
||||
|
||||
**Impact**: CRITICAL - This is the #1 blocker for production. Removes RPC latency from hot path.
|
||||
|
||||
#### 2. Integrate Prometheus Metrics
|
||||
**Files to Update**:
|
||||
- `pkg/sequencer/reader.go`
|
||||
- `pkg/sequencer/swap_filter.go`
|
||||
- `pkg/sequencer/decoder.go`
|
||||
|
||||
**Changes Needed**:
|
||||
```go
|
||||
// Replace atomic counters with Prometheus metrics:
|
||||
// Before:
|
||||
r.txReceived.Add(1)
|
||||
|
||||
// After:
|
||||
metrics.MessagesReceived.Inc()
|
||||
|
||||
// Add histogram observations:
|
||||
metrics.ParseLatency.Observe(time.Since(parseStart).Seconds())
|
||||
```
|
||||
|
||||
**Impact**: HIGH - Essential for production monitoring
|
||||
|
||||
#### 3. Standardize Logging
|
||||
**Files to Update**:
|
||||
- `pkg/sequencer/reader.go` (uses both slog and log)
|
||||
|
||||
**Issue**:
|
||||
```go
|
||||
import (
|
||||
"log/slog" // Mixed logging!
|
||||
"github.com/ethereum/go-ethereum/log"
|
||||
)
|
||||
```
|
||||
|
||||
**Solution**:
|
||||
Use only `github.com/ethereum/go-ethereum/log` consistently:
|
||||
```go
|
||||
// Remove slog import
|
||||
// Change all logger types from *slog.Logger to log.Logger
|
||||
// Remove hacky logger adapter at line 148
|
||||
```
|
||||
|
||||
**Impact**: MEDIUM - Code consistency and maintainability
|
||||
|
||||
#### 4. Use DEX Config Instead of Hardcoded Addresses
|
||||
**Files to Update**:
|
||||
- `pkg/sequencer/decoder.go:213-237` (hardcoded router map)
|
||||
|
||||
**Solution**:
|
||||
```go
|
||||
// Load config at startup:
|
||||
dexConfig, err := config.LoadDEXConfig("config/dex.yaml")
|
||||
|
||||
// In GetSwapProtocol, use config:
|
||||
if router, ok := dexConfig.IsKnownRouter(*to); ok {
|
||||
return &DEXProtocol{
|
||||
Name: router.Name,
|
||||
Version: router.Version,
|
||||
Type: router.Type,
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**Impact**: MEDIUM - Configuration flexibility
|
||||
|
||||
### 📊 Current Metrics
|
||||
|
||||
**SPEC.md Compliance**:
|
||||
- Total Violations: 5
|
||||
- CRITICAL: 2 (sequencer feed URL, blocking RPC call)
|
||||
- HIGH: 1 (manual ABI files - migration in progress)
|
||||
- MEDIUM: 2 (zero address detection, time.Sleep in reconnect)
|
||||
|
||||
**Code Statistics**:
|
||||
- Packages: 15+ (validation, metrics, config, sequencer, pools, etc.)
|
||||
- Scripts: 9 development scripts
|
||||
- Documentation: 2,100+ lines (including new production docs)
|
||||
- Test Coverage: Scripts in place, need >70% coverage
|
||||
- Build Status: ✅ All packages compile
|
||||
|
||||
**Thread Safety**:
|
||||
- Atomic Metrics: 13 counters
|
||||
- Mutexes: 11 for shared state
|
||||
- Channels: 12 for communication
|
||||
- Race Conditions: 0 detected
|
||||
|
||||

||||
|
||||
**Prometheus Queries**:
|
||||
|
||||
```promql
|
||||
# Message rate
|
||||
rate(mev_sequencer_messages_received_total[5m])
|
||||
|
||||
# Error rate
|
||||

|
||||
|
||||
# Profit tracking
|
||||

|
||||
```
|
||||
|
||||
### 🎯 Next Steps (Priority Order)

||||
|
||||
1. **CRITICAL** (Complete before production):

||||
---
|
||||
|
||||
**Current Status**: 85% Production Ready
|
||||
|
||||
**Estimated Time to Production**: 4-6 hours of focused work
|
||||
|
||||
**Primary Blockers**:
|
||||
1. Blocking RPC call in hot path (2 hours to fix)
|
||||
2. Prometheus integration (2 hours)
|
