Security cannot be an afterthought; it's the make-or-break factor. Crypto exchanges are prime targets for hackers, as seen in past breaches like Mt. Gox. Employ HTTPS everywhere, rate limiting with express-rate-limit, and input validation using Joi or Zod. Store the bulk of funds in cold storage—offline wallets—using multi-signature schemes for withdrawals requiring multiple approvals. Hot wallets for immediate trades should hold minimal balances, automated via cron jobs. Implement two-factor authentication with TOTP and IP whitelisting. Audit your code for vulnerabilities like reentrancy in smart contract interactions or SQL injection. Regularly rotate API keys and use hardware security modules (HSMs) for production-grade key management.
