Py-EVM is a Python implementation of the Ethereum Virtual Machine, designed to be readable, flexible, and suitable for research, experimentation, and testing. The repository has been archived and is read-only, with development continuing in the ethereum/execution-specs repo.
Use cases
- run the ethereum virtual machine in python
- experiment with evm opcodes and protocol changes
- test python ethereum tooling against a reference evm
- understand how the evm executes bytecode
- prototype execution layer specification changes
When to choose
- you need a readable, hackable EVM implementation for research or testing
- you want a Python-native EVM for tooling and test suites
When to avoid
- you need a maintained implementation - use ethereum/execution-specs instead
- you need a production node or consensus layer
- you need maximum performance
