It provides encoding and decoding for a range of data types\u2014from basic integers and booleans to complex aggregates like vectors and bit sequences\u2014using little-endian fixed-width and compact integer formats to minimize network overhead.\n\nThe package is typically used by developers building tools, wallets, or indexers that interact with Substrate chains, where they need to serialize Python objects into SCALE format for on-chain calls or deserialize chain data back into Python types. It depends on more-itertools, base58, and requests, and targets Python 3.6 and later.","worth_installing":"Yes, if you are building on Substrate or Polkadot. The package is stable, permissively licensed, and has low install friction. Maintenance is aging but the repository is not archived and the package remains in active use. No known vulnerabilities. Not relevant for non-blockchain Python projects."},"id":"scalecodec","links":{"html":"https://skillfed.io/packages/scalecodec","md":"https://skillfed.io/packages/scalecodec.md","pypi":"https://pypi.org/project/scalecodec/"},"maintenance":{"status":"aging"},"meta":{"latest_release":"2025-10-16","license_spdx":null,"license_treatment":"permissive","name":"scalecodec","python_support":"supports_current","summary":"Python SCALE Codec Library"},"popularity":{"monthly_downloads":345396,"position":7363,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"1.2.12"}
