Library for secure smart contract development written in Cairo

Project description

OpenZeppelin Cairo Contracts

Tests and linter

A library for secure smart contract development written in Cairo for StarkNet, a decentralized ZK Rollup.

⚠️ WARNING! ⚠️

This is repo contains highly experimental code. Expect rapid iteration. Do not use in production.

Installation

First time?

Before installing Cairo on your machine, you need to install gmp:

sudo apt install -y libgmp3-dev # linux
brew install gmp # mac

If you have any troubles installing gmp on your Apple M1 computer, here’s a list of potential solutions.

Set up the project

Clone the repository

git clone git@github.com:OpenZeppelin/cairo-contracts.git

cd into it and create a Python virtual environment:

cd cairo-contracts
python3 -m venv env
source env/bin/activate

Install the Nile dev environment and then run install to get the Cairo language, a local network, and a testing framework.

pip install cairo-nile
nile install

Usage

Compile the contracts

nile compile --directory openzeppelin
