faster-eth-utils
A faster fork of eth-utils: Common utility functions for python code that interacts with Ethereum. Implemented in C.
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.
Worth the install?
AI-flagged interpretation of the facts on this page — verify before relying
Provides Ethereum utility functions for address validation, type conversions, and encoding operations, implemented in C for faster execution than the original eth-utils.
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.
Install

Before you install
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.
License in practice
MIT license permits commercial and private use with minimal restrictions; you may use, modify, and distribute this package freely provided you retain the license notice.
Quickstart
pip install faster-eth-utils
from faster_eth_utils import is_address
result = is_address('0xabcdef')
Requires Python 3.10 or later; precompiled wheels available for common platforms but may require compilation on unsupported architectures.
Verify before relying
- Specific performance improvement margins over eth-utils (description mentions benchmarks but does not quantify them in the excerpt).
- Whether exception compatibility with eth-utils (claimed since v5.3.11) is maintained in version 5.3.29.
- Full API surface coverage relative to the upstream eth-utils package.
- Which specific utility functions are provided (address validation, encoding, type conversion, etc.).
