Description:

alephsdkpython 1.0.1

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 testing: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
