aleph-sdk-python

Python SDK for the Aleph.im network, next generation network of decentralized big data applications.

Development follows the Aleph Whitepaper.

Documentation

The latest documentation, albeit incomplete, is available at https://docs.aleph.im/libraries/python-sdk/.

For the full documentation, please refer to the docstrings in the source code.

Requirements

Linux

Some cryptographic functionalities use curve secp256k1 and require installing libsecp256k1.

$ apt-get install -y python3-pip libsecp256k1-dev

Using some chains may also require installing libgmp3-dev.

macOs

This project does not support Python 3.12 on macOS. Please use Python 3.11 instead.

$ brew tap cuber/homebrew-libsecp256k1
$ brew install libsecp256k1

Installation

Using pip and PyPI:

$ pip install aleph-sdk-python

Additional dependencies

Some functionalities require additional dependencies. They can be installed like this:

$ pip install aleph-sdk-python[solana, dns]

The following extra dependencies are available:

• solana for Solana accounts and signatures
• cosmos for Substrate/Cosmos accounts and signatures
• nuls2 for NULS2 accounts and signatures
• polkadot for Polkadot accounts and signatures
• ledger for Ledger hardware wallet support, see Usage with LedgerHQ hardware
• mqtt for MQTT-related functionalities, see examples/mqtt.py
• docs for building the documentation, see Documentation
• dns for DNS-related functionalities
• all installs all extra dependencies

Installation for development

Setup a virtual environment using hatch:

$ hatch shell

Then install the SDK from source with all extra dependencies:

$ pip install -e .[all]

Running tests & Hatch scripts

You can use the test env defined for hatch to run the tests:

$ hatch run test:run

See hatch env show for more information about all the environments and their scripts.

Generating the documentation [DEPRECATED]

The documentation is built using Sphinx.

To build the documentation, install the SDK with the docs extra dependencies:

$ pip install -e .[docs]

Then build the documentation:

$ cd docs
$ make html

Usage with LedgerHQ hardware

The SDK supports signatures using app-ethereum, the Ethereum app for the Ledger hardware wallets.

This has been tested successfully on Linux (amd64). Let us know if it works for you on other operating systems.

Using a Ledger device on Linux requires root access or the setup of udev rules.

Unlocking the device is required before using the relevant SDK functions.

Debian / Ubuntu

Install ledger-wallets-udev.

sudo apt-get install ledger-wallets-udev

On NixOS

Configure hardware.ledger.enable = true.

Other Linux systems
