Security Report

4.2
Use Caution4.2High Risk

SaturnZap is a well-architected Lightning Network wallet for AI agents with sound security fundamentals. Authentication is properly handled through passphrase-protected seed storage and LDK node key management. Permissions are appropriately scoped for a financial application (network HTTP, file I/O, environment variables). Minor code quality concerns around broad exception handling and incomplete input validation exist but do not constitute significant security vulnerabilities. Supply chain analysis found 8 known vulnerabilities in dependencies (0 critical, 7 high severity). Package verification found 1 issue.
