**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:**
- ✅ API keys loaded from environment variables
- ✅ `.env` file in `.gitignore`
- ✅ `.env.example` provided for reference (no real keys)
- ✅ Key masking in logs and API responses
- ✅ No hardcoded keys in source code

**Optional Hardening (For Internet Deployment):**
- ⚠️ Add JWT/OAuth2 authentication (if exposing dashboards)
- ⚠️ Enable HTTPS (use Nginx + Let's Encrypt)
- ⚠️ Add rate limiting per IP (prevent abuse)
- ⚠️ Implement firewall rules (UFW)

**Verdict**: ✅ **SECURE** - Production-grade security for internal deployment
