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:
- β API keys loaded from environment variables
- β
.envfile in.gitignore - β
.env.exampleprovided for reference (no real keys) - β Key masking in logs and API responses
- β No hardcoded keys in source code
- β SQLAlchemy ORM (SQL injection protection)
- β Pydantic validation (input sanitization)
Optional Hardening (For Internet Deployment):
- β οΈ Add JWT/OAuth2 authentication (if exposing dashboards)
