Yes, if you are developing on the Chia blockchain and need access to the standard puzzle definitions and their compiled forms. No, if you are not working with Chia or do not need to reference these specific puzzles. Caveat: verify the license terms before use, as they are not clearly stated in the package metadata; also note that the package is aging (304 days since last release) and may not receive updates for new puzzle deployments.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.8 or later.
- Depends on clvm-rs and clvm-tools-rs, which may require a Rust toolchain or prebuilt binaries for your platform.
- Low install friction; pure Python wheel with three runtime dependencies (clvm-rs, clvm-tools-rs, pytest).

What it is and what it does
chia-puzzles-py is a Python library that exposes the standard Chia puzzles—the immutable ChiaLisp programs deployed on the Chia blockchain—as Python constants and bindings. It tracks the source code (.clsp files), compiled hex representations (.clsp.hex files), and cryptographic hashes to ensure integrity and continuity of these critical blockchain components. The puzzles are generated from a source repository and cannot change once deployed on chain, so this library serves as a stable reference implementation.
The package is primarily used by Chia ecosystem developers who need to interact with or verify these standard puzzles programmatically. It depends on clvm-rs and clvm-tools-rs for ChiaLisp compilation and execution, and pytest for testing. The library is maintained as a pure Python wheel with no compiled extensions of its own, making installation straightforward on supported Python versions (3.8 through 3.14).
Use it for
- Reference the compiled hex and hash of standard Chia puzzles in blockchain transaction validation or wallet software.
- Verify puzzle integrity by comparing computed hashes against the bundled constants.
- Develop Chia smart contracts or dApps that need to interact with or call standard puzzles.
- Test ChiaLisp puzzle implementations against the canonical on-chain versions.
