### ⚠️ REMAINING ISSUE (Partial Fix)
|
||||
|
||||
#### Zero Address in Liquidity Events ⚠️
|
||||
**Status**: **PARTIALLY RESOLVED** - Needs additional fix
|
||||
|
||||
**Current Situation**:
|
||||
- **Analysis reports**: 0 zero address issues
|
||||
- **Actual reality**: 64 zero addresses in today's liquidity events (32 events with 2 addresses each)
|
||||
- **Swap events**: Validating correctly (0 bytes = new session)
|
||||
|
||||
**Evidence**:
|
||||
```bash
|
||||
# Count zero addresses in liquidity events
|
||||
jq -r '.token0Address, .token1Address' logs/liquidity_events_2025-10-30.jsonl | \
|
||||
grep "0x0000000000000000000000000000000000000000" | wc -l
|
||||
# Result: 64 (out of 129 total events = 32 events with zero addresses)
|
||||
|
||||
# Sample liquidity event
|
||||
{"token0Address":"0x0000000000000000000000000000000000000000",
|
||||
"token1Address":"0x0000000000000000000000000000000000000000",
|
||||
"factory":"0x0000000000000000000000000000000000000000",
|
||||
"protocol":"UniswapV3"}
|
||||
```
|
||||
|
||||
**Root Cause Analysis**:
|
||||
1. Liquidity events are logged **before** validation runs
|
||||
2. Validation utilities created (`pkg/utils/address_validation.go`) but **not integrated** into liquidity event logging path
|
||||
3. Swap events likely use different code path with validation
|
||||
|
||||
**Impact**:
|
||||
- **LOW** - Liquidity events are for monitoring only
|
||||
- **Does not affect** core arbitrage detection
|
||||
- **Does not affect** swap event processing (working correctly)
|
||||
- **Does not affect** block processing or DEX transaction detection
|
||||
|
||||
**Required Fix** (Priority: MEDIUM):
|
||||
```go
|
||||
// File: pkg/marketdata/logger.go or equivalent liquidity event logger
|
||||
|
||||
import "github.com/fraktal/mev-beta/pkg/utils"
|
||||
|
||||
func LogLiquidityEvent(event *LiquidityEvent) error {
|
||||
// ADD VALIDATION BEFORE LOGGING
|
||||
if err := utils.ValidateAddresses(map[string]common.Address{
|
||||
"token0": event.Token0Address,
|
||||
"token1": event.Token1Address,
|
||||
"factory": event.Factory,
|
||||
}); err != nil {
|
||||
return fmt.Errorf("invalid liquidity event addresses: %w", err)
|
||||
}
|
||||
|
||||
// Proceed with logging only if validation passes
|
||||
return writeToJSONL(event)
|
||||
}
|
||||
```
|
||||
|
||||
**Workaround** (Immediate):
|
||||
- Filter zero addresses when reading liquidity events
|
||||
- Use swap events as primary data source (they validate correctly)
|
||||
- Liquidity events supplementary only
