Aleo SDK


aleo on PyPI

Aleo Python bindings for building zero-knowledge applications.

This project uses PyO3 and Maturin to provide a Python library named aleo that binds to snarkVM Rust functionalities. The resulting aleo library can be easily installed and used within Python. The project is at an early stage. At the moment, only Mac OS 11 or newer on Apple Silicon is supported - support for other operating systems will follow. If you are using another operating system, you may be able to build the library yourself following the instructions below.

Supported functionalities currently include:

  • Private key generation


The aleo Python library is available on PyPI for installation.


Ensure you have Python 3.11 or newer installed. If your operating system is supported, you can install the library from pip:

pip3 install aleo

Alternatively, you can also install from a .whl file, either from the GitHub repository, or by building it yourself. For the installation, use a command like this:

pip3 install aleo-0.0.3-cp311-cp311-macosx_11_0_arm64.whl

Note: On some systems, you may need to use pip instead of pip3.

Example use

You can import the library, generate a private key object, and print it as a string as in the following example:

import aleo
private_key = aleo.PrivateKey()

Build Instructions

To build it, first clone the GitHub repository. Then, run the following command:


After successful building, you will find a new .whl file in the target/wheels directory that you can install using the command from above.

Building Python Apps

Further documentation and tutorials as to how to use the aleo Python library will follow soon.
