pyontio 0.0.7

Comprehensive Python library for the Ontology BlockChain.

Ontology Python SDK

Introduction

The Ontology official Python SDK is a comprehensive SDK which is based on Python3.6. Currently, it supports local wallet management, digital identity management, digital asset management, deployment and invoke for smart contract, the calling of OEP4, and communication with the Ontology blockchain. The future will also support more functions and applications.

Preparations

Installation requires a Python 3.7 or later environment.

pip install ontology-python-sdk
