What it is and what it does
eth-typing is a library that defines common type annotations used across Ethereum Python packages. It provides standardized type hints for Ethereum-specific concepts, allowing developers to write type-safe code when working with Ethereum in Python.
The package is maintained as part of the Ethereum ecosystem and serves as a foundational layer for type consistency across related libraries. It has a single runtime dependency (typing_extensions) and supports Python 3.10 through 3.14, making it lightweight and easy to integrate into existing projects.
Use it for
- Define type-safe function signatures when building Ethereum smart contract interaction libraries.
- Ensure consistent type annotations across multiple Ethereum-related Python packages in a project.
- Reduce boilerplate by importing pre-defined Ethereum types instead of defining them locally.
- Enable IDE autocompletion and static type checking for Ethereum-specific data structures.
