ZeppelinOS Command Line Interface

This package provides a unified command line interface to ZeppelinOS.

ZeppelinOS is a platform to develop, manage and operate smart contract applications in Ethereum. It can be used to create smart contract systems that can be fixed and improved over time, enabling developers to opt-in to mutability for their deployed code through upgradeability patterns. zos also provides an interface to connect your application code to already deployed standard libraries.

If you're looking for a lower-level development experience, see zos-lib.

Getting Started

Install

To install zos simply run:

npm install --global zos

Basic usage

Before you begin

mkdir myproject && cd myproject
npm init

Setup your project

Initialize your project with ZeppelinOS. The next command will create a new zos.json file:

zos init <name> [version]

Where <name> is your project's name, and [version] an optional initial version name. For example:

zos init my-project 0.1.0
