+ "Optimized C library for cryptographic operations on curve secp256k1.
+
+This library is used for consensus critical cryptographic operations on the
+Bitcoin Cash network.
+
+Features:
+
+@itemize
+@item secp256k1 ECDSA signing/verification and key generation.
+@item secp256k1 Schnorr signing/verification (Bitcoin Cash Schnorr variant).
+@item Additive and multiplicative tweaking of secret/public keys.
+@item Serialization/parsing of secret keys, public keys, signatures.
+@item Constant time, constant memory access signing and pubkey generation.
+@item Derandomized ECDSA (via RFC6979 or with a caller provided function).
+@item Very efficient implementation.
+@item Suitable for embedded systems.
+@item Optional module for public key recovery.
+@item Optional module for ECDH key exchange (experimental).
+@item Optional module for multiset hash (experimental).
