-The secp256r1 curve (also known as NIST P-256) is commonly used in traditional PKI and secure communications.
+Various systems calls for computations over the secp256r1 curve (also known as NIST P-256).
+
+These system calls are particularly useful when implementing traditional PKI or secure communication functionality, as secp256r1 is widely used in TLS, secure messaging, and government standards.
 
 [IMPORTANT]
-Note that instead of using these syscalls directly, it is recommended to use the traits and implementations provided in the https://docs.swmansion.com/scarb/corelib/core-starknet-secp256r1.html[`secp256_module`^] which provide a more convenient interface and handle the syscalls under the hood.
