clvm-rs
Implementation of `clvm` for Chia Network's cryptocurrency
Decision gist · record as of 2026-08-14
Yes, if you are building on Chia Network or need to execute Chia smart contracts from Python. The package is actively maintained, has no vulnerabilities, and offers prebuilt wheels for common platforms. Install friction is moderate due to compilation, but prebuilt binaries mitigate this for standard environments. Not relevant for non-Chia projects.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires a compatible Python version and platform with prebuilt wheels (macOS 15.0+, manylinux_2_28, or Windows); source compilation requires Rust toolchain and maturin.
- Medium install friction due to compiled Rust wheels; prebuilt binaries available for common platforms (macOS arm64/x86_64, Linux x86_64/aarch64, Windows x86_64).
- Active maintenance with recent release 9 days old.

What it is and what it does
clvm-rs is a Rust implementation of CLVM, the virtual machine that executes Chia Network's smart contracts and blockchain logic. It provides Python bindings via compiled wheels, allowing developers to run and validate Chia programs from Python without reimplementing the VM in pure Python. The package has no runtime dependencies and is built as a native extension, making it performant for cryptographic operations.
The package is actively maintained by Chia Network and includes prebuilt wheels for major platforms. It supports optional OpenSSL integration for faster SHA256 operations. Developers typically use it to interact with Chia's blockchain, validate smart contracts, or integrate Chia logic into Python applications.
Use it for
- Execute Chia smart contract code (clvm programs) from Python applications
- Validate and test Chia blockchain transactions and coin spends
- Build Chia wallet or node software that needs to run contract logic
- Integrate Chia cryptocurrency functionality into Python services
