It wraps the CPU-intensive checksum computation in C code, delivering roughly 18x faster execution while keeping the same function signature, return values, and exception behavior. The package is designed as a drop-in replacement: you install it, import from cchecksum instead of eth_utils, and your existing code runs faster without modification.\n\nThe package depends on eth-hash, eth-typing, pysha3, and safe-pysha3 for cryptographic operations and type definitions. It targets CPython 3.9 through 3.14 and ships pre-compiled wheels for multiple architectures, reducing installation friction on standard platforms. With no known vulnerabilities and active maintenance, it is suitable for production use in Ethereum tooling and applications where address validation throughput matters.","worth_installing":"Yes, if you use Ethereum address checksum validation in a performance-sensitive context. The identical API and exception behavior make it a true drop-in replacement with no code changes required. Active maintenance, no vulnerabilities, and broad platform coverage make it low-risk. Install if the stated speedup justifies the medium wheel-installation friction on your target platforms."},"id":"cchecksum","links":{"html":"https://skillfed.io/packages/cchecksum","md":"https://skillfed.io/packages/cchecksum.md","pypi":"https://pypi.org/project/cchecksum/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-07-10","license_spdx":null,"license_treatment":"permissive","name":"cchecksum","python_support":"supports_current","summary":"An ~18x faster drop-in replacement for eth_utils.to_checksum_address.
