Python SDK for the Cosmos Ecosystem

_{(Unfamiliar with Cosmos? Check out the Cosmos Network Docs)}

This (SDK) in Python is a simple library toolkit for building software that can interact with the supported Cosmos blockchains and provides simple abstractions over core data structures, serialization, key management, and API request generation.

Note - This is currently a W.I.P.

Features

• This SDK follows a module specific approach, and new Cosmos Modules will be added to the SDK on a priority basis.
• Written in Python with extensive support libraries
• Versatile support for key management solutions

❗ This SDK currently does not support Terra Classic. If you want to communicate with Terra Classic, use terra-sdk==2.x

Requirements

Cosmos.py SDK requires Python v3.7+.

Installation

_{NOTE: All code starting with a $ is meant to run on your terminal (a bash prompt). All code starting with a >>> is meant to run in a python interpreter, like ipython.}

Cosmos SDK can be installed (preferably in a virtual environment from PyPI using pip) as follows:

$ pip install -U cosmos_SDK

_{You might have pip3 installed instead of pip; proceed according to your own setup.}

Usage Examples

from cosmos_sdk.client.lcd import LCDClient
from cosmos_sdk.key.mnemonic import MnemonicKey

mnemonic = <MNEMONIC_PHRASE>

# Terra client
terra_client = LCDClient(chain_id="phoenix-1", url="https://phoenix-lcd.terra.dev")
mk = MnemonicKey(mnemonic,"terra")
terra_wallet = terra_client.wallet(mk)

# Persistence client
persistence_client = LCDClient(chain_id="core-1", url="http://rest.core.persistence.one")
mk = MnemonicKey(mnemonic,"persistence")
persistence_wallet = persistence_client.wallet(mk)

Dependencies

Cosmos SDK uses Poetry to manage dependencies. To get set up with all the required dependencies, run:

$ pip install poetry
$ poetry install

If you encounter "version solving failed." error, try poetry add <package_name>, followed by poetry lock and then poetry install
