## TLS Certificate Pinning

TLS Certificate Pinning is a security technique used in mobile and desktop applications to ensure that the application only communicates with a specific, pre-defined server certificate. By hardcoding the server's public key or certificate within the application code, developers prevent attackers from using fraudulent certificates to intercept traffic.

In financial applications, this is a vital defense against Man-in-the-Middle attacks where an attacker might attempt to present a fake certificate to decrypt and view private user data. Unlike standard browser-based validation, which relies on a wide list of trusted authorities, pinning restricts the trust to a specific entity.

This reduces the attack surface significantly by ensuring that the connection is exclusively between the trusted client and the legitimate server. It provides an extra layer of protection for users accessing high-value derivative platforms or exchange interfaces.

If a connection is attempted with a certificate that does not match the pinned one, the application will terminate the session immediately.
