This article covers engineering practices, not legal compliance. It makes no claim that following it makes a platform secure or compliant; that depends on assessment, testing and your jurisdictions.
Access control
Apply least privilege everywhere. Back-office roles should be narrow, sensitive actions (balance adjustments, limit changes, market overrides) should need elevated rights, and every such action should be logged with who, what and when.
Wallet integrity
Use a ledger with immutable entries, idempotent operations and constraints that prevent negative balances where they are not allowed. Reconcile regularly.
Secrets and configuration
Keep secrets out of source control and rotate them. Separate credentials per environment and per provider.
Input and API security
Validate inputs on the server, rate-limit public endpoints and protect against common web vulnerabilities. The OWASP ASVS provides a structured checklist of requirements you can adopt level by level.
Dependencies
Track and update dependencies and scan for known vulnerabilities as part of CI.
Logging and monitoring
Log security-relevant events and alert on anomalies such as bursts of failed logins or unusual withdrawal patterns. Avoid logging sensitive data.
Testing
Combine automated checks with periodic independent penetration testing. Fix findings with owners and deadlines.
Incident readiness
Have a documented plan for who does what when something goes wrong, and rehearse it.
Compliance is separate
Regulatory and certification requirements depend on where and how you operate. Work with qualified advisers and your regulator's published requirements.
