OpenZeppelin SDK Command-Line Interface (@openzeppelin/cli)

standard-readme compliant NPM Package CircleCI

Command-line interface for the OpenZeppelin smart contract platform.

OpenZeppelin SDK is a platform to develop, deploy and operate smart contract projects on Ethereum and every other EVM and eWASM-powered blockchain.

This is the repository for the OpenZeppelin commmand-line interface, the recommended way to use the OpenZeppelin SDK.


First, install Node.js and npm. Then, install the OpenZeppelin SDK running:

npm install --global @openzeppelin/cli


To start, create a directory for the project and access it:

mkdir my-project
cd 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 add contracts to the project with the openzeppelin add command, push these contracts to a blockchain network with openzeppelin push, use openzeppelin create to create instances for these contracts that later can be upgraded, and many more things.

Run openzeppelin --help for more details about this and all the other functions of the OpenZeppelin CLI.

The OpenZeppelin SDK documentation explains how to use the openzeppelin command-line interface to build a project, to upgrade contracts and to share packages for other projects to reuse. It also explains how to operate the project with the OpenZeppelin JavaScript libraries instead of this openzeppelin command.


If you find a security issue, please contact us at We give rewards for reported issues, according to impact and severity.
