It executes Ethereum bytecode and processes transactions according to the protocol specification, with a focus on clarity and modifiability over raw speed.\n\nThe package is built on a stack of Ethereum-specific cryptographic and data-structure libraries (eth-bloom, eth-keys, eth-typing, eth-utils, py-ecc, rlp, trie, and ckzg) and provides chainable interfaces for constructing and simulating Ethereum execution. It is intended as a reference implementation and testing tool rather than a production execution client, and is suitable for developers building Python-based Ethereum applications, running protocol experiments, or validating smart contract behavior in isolation.","worth_installing":"No, not for new projects. While py-evm is well-designed and has low install friction, the repository is archived and abandoned\u2014no maintenance, security patches, or bug fixes will be provided. Its 10 dependencies may themselves become stale. Install only if you are maintaining an existing codebase that already depends on it, or if you are conducting time-limited research where you accept the stability and security risks."},"id":"py-evm","links":{"html":"https://skillfed.io/packages/py-evm","md":"https://skillfed.io/packages/py-evm.md","pypi":"https://pypi.org/project/py-evm/"},"maintenance":{"status":"abandoned"},"meta":{"latest_release":"2025-05-14","license_spdx":null,"license_treatment":"permissive","name":"py-evm","python_support":"supports_current","summary":"Python implementation of the Ethereum Virtual Machine"},"popularity":{"monthly_downloads":280173,"position":8114,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"0.12.1b1"}
