**Verification Result**: **FALSE ALARM - SECURE**

**Findings:**
```python
# config.py lines 100-112 - ALL keys loaded from environment
ETHERSCAN_KEY_1 = os.getenv('ETHERSCAN_KEY_1', '')
BSCSCAN_KEY = os.getenv('BSCSCAN_KEY', '')
COINMARKETCAP_KEY_1 = os.getenv('COINMARKETCAP_KEY_1', '')
NEWSAPI_KEY = os.getenv('NEWSAPI_KEY', '')
# ... etc
```

**Security Measures In Place:**
