2.7.5.1 Logging & Audit Trails

• Structured Logs (Winston or Pino)

• Include relevant request metadata: user ID, route, IP, timestamps.

• Maintain logs for critical actions (trade execution, user role changes, wallet links).

• Immutable Audit Records

• For financial compliance, store trade logs (who traded, what, when) in a tamper-resistant format (append-only or cryptographically signed).
