Centralized Crypto Exchange System Architecture Explained

How do centralized crypto exchanges ensure user security?

Centralized crypto exchanges implement robust, multi-layered security protocols to protect user accounts and digital assets from unauthorized access and cyber threats. This comprehensive approach includes stringent identity verification processes like KYC, alongside strong authentication mechanisms such as 2FA. These measures are crucial for preventing fraud, safeguarding sensitive user data, and maintaining the platform's integrity, thereby building essential trust within the trading community.
