OpenZeppelin SDK is not being actively developed. We recommend using Upgrades Plugins instead. For more information, see Building for interoperability: why we’re focusing on Upgrades Plugins.

Command Line Interface (CLI)

Develop, deploy and operate upgradeable smart contract projects. Support for Ethereum and every other EVM-powered blockchain.

Interactive commands: Send transactions, query balances, and interact with your contracts directly from the command line, using commands like oz send-tx, oz call, oz balance, and oz transfer.
Deploy & upgrade your contracts: You can develop your smart contracts iteratively, speeding up development locally, or squashing bugs in production. Run oz create to deploy your contracts, followed by oz upgrade any time you want to change their code.
Link Ethereum Packages: Use code from contracts already deployed to the blockchain directly on your project, saving gas on deployments and managing your dependencies securely, just with an oz link command.
Bootstrap your dapp: Jumpstart your dapp by unpacking one of our starter kits, pre-configured with OpenZeppelin Contracts, React, and Infura. Run oz unpack to start!

Overview

$ npm install @openzeppelin/cli

All CLI commands are fully interactive: you can call them with no or incomplete arguments and they will prompt you for options as they proceed.

Below is a short list of the most used commands:

oz init: initialize your OpenZeppelin project
oz compile: compile all Solidity smart contracts in your project
oz create: deploy an upgradeable smart contract
oz send-tx: send a transaction to a contract and execute a function
oz call: read data from the blockchain by calling view and pure functions
oz upgrade: upgrade a deployed contract to a new version without changing the address or state
oz unpack: bootstrap a project with a Starter Kit
oz link: reuse on-chain code by to a linking to Ethereum Packages
