faster-eth-utils
A faster fork of eth-utils: Common utility functions for python code that interacts with Ethereum. Implemented in C.
Decision gist · record as of 2026-08-14
Yes, if you already use eth-utils and want faster execution without rewriting code. The C compilation, active maintenance, and exception compatibility make it a low-risk swap. Install friction is moderate due to compiled wheels, but prebuilt binaries cover common platforms. No known vulnerabilities and permissive MIT license. Not worth installing if you don't use eth-utils or if your bottleneck is elsewhere.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.10 or later; precompiled wheels available for common platforms but may require compilation on unsupported architectures.
- Medium install friction due to compiled wheels across many platforms (CPython 3.10–3.14, macOS, Linux, Windows, ARM).
- Active maintenance with a release 34 days ago; repo shows recent commits and is not archived.

What it is and what it does
faster-eth-utils is a C-compiled fork of eth-utils that provides common utility functions for Ethereum development. It maintains API compatibility with eth-utils while trading compilation overhead for runtime speed. The package depends on eth-utils, eth-typing, eth-hash, pydantic, toolz, cytoolz, cchecksum, and mypy-extensions.
The fork is kept in sync with upstream eth-utils releases and exception classes inherit from their eth-utils counterparts, so existing exception handlers continue to work without modification. It supports Python 3.10 through 3.14 on CPython and ships precompiled wheels for macOS, Linux (multiple architectures), Windows, and ARM platforms, reducing installation friction on common systems.
Use it for
- Use as a drop-in replacement for eth-utils in existing Ethereum projects to gain performance without code changes.
- Accelerate utility-heavy Ethereum tooling where address validation or encoding is a performance bottleneck.
- Support modern Python versions (3.10–3.14) in Ethereum projects that need current language features.
- Maintain existing exception handling when migrating from eth-utils due to inherited exception class compatibility.
- Deploy on diverse platforms (macOS, Linux, Windows, ARM) using precompiled wheels to avoid build overhead.
