How NestJS Handles Secure Transactions in Banking Applications

NestJS provides structured patterns for secure banking through guards that verify every transaction, interceptors that auto-log for compliance, and dependency injection for testable transaction logic. Its enforced architecture ensures security controls are consistent across teams. The framework scales from startups to multi-service platforms with built-in microservice support.
