It handles ECDSA signing and verification, ECDH key exchange, and Schnorr signatures\u2014the cryptographic primitives underlying blockchain systems.\n\nThe package is used by major projects including Ethereum, LBRY, and libp2p. It supports Python 3.9 through 3.13 and both CPython and PyPy implementations. Installation is straightforward on common platforms thanks to prebuilt wheels; on less common architectures, you may need a C compiler and libsecp256k1 development headers.","worth_installing":"Yes. coincurve is production-stable, actively maintained, widely adopted in blockchain infrastructure, has no known vulnerabilities, and offers fast Python bindings to secp256k1. Install it if you need secp256k1 operations; the medium install friction is justified by the performance and correctness guarantees of the underlying C library."},"id":"coincurve","links":{"html":"https://skillfed.io/packages/coincurve","md":"https://skillfed.io/packages/coincurve.md","pypi":"https://pypi.org/project/coincurve/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2025-03-08","license_spdx":"MIT OR Apache-2.0","license_treatment":"permissive","name":"coincurve","python_support":"supports_current","summary":"Safest and fastest Python library for secp256k1 elliptic curve operations"},"popularity":{"monthly_downloads":3254947,"position":2683,"tier":"top_5000"},"security":{"n_vulnerabilities":0},"version":"21.0.0"}
