OpenZeppelin SDK
Formerly known as ZeppelinOS
OpenZeppelin is a platform to develop, deploy and operate smart contract projects on Ethereum and every other EVM and eWASM-powered blockchain.
This repository includes the OpenZeppelin Command-Line Interface and Upgrades Library.
Install
First, install Node.js and npm. Then, install the OpenZeppelin SDK running:
npm install --global @openzeppelin/cli
If you get an
EACCESS permission denied
error while installing, please refer to the npm documentation on global installs permission errors. Alternatively, you may runsudo npm install --unsafe-perm --global @openzeppelin/cli
, but this is highly discouraged, and you should rather either use a node version manager or manually change npm's default directory.
Usage
We recommend to use the OpenZeppelin SDK through the openzeppelin sdk
command-line interface.
To start, create a directory for the project and access it:
mkdir my-projectcd my-project
Use npm
to create a package.json
file:
npm init
And initialize the OpenZeppelin SDK project:
openzeppelin init my-project
Now it is possible to use openzeppelin deploy
to create instances for these contracts that
later can be upgraded, and many more things.
Run openzeppelin --help
for more details about thes and all the other functions of the
OpenZeppelin CLI.
The OpenZeppelin SDK documentation explains how to build a project using our platform, how to upgrade contracts, how to share packages for other projects to reuse, how to vouch for the quality of a package, how to use the JavaScript libraries to operate the project, and it explains details of the platform and some advanced topics.
