Installation

First time?

Further installation instructions provided in the cairo-lang docs

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.

For VSCode support:

Download cairo-0.6.2.vsix from https://github.com/starkware-libs/cairo-lang/releases/tag/v0.6.2

And run:

code --install-extension cairo-0.6.2.vsix

Set up the project

Clone the repository

git clone [email protected]:a5f9t4/cairomate.git

cd into it and create a Python virtual environment:

cd cairomate
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.

pip3 install cairo-nile
nile install

Usage

Compile the contracts

nile compile

Run tests

pytest

Extending Cairo contracts

There’s no clear contract extensibility pattern for Cairo smart contracts yet. In the meantime the best way to extend our contracts is copypasting and modifying them at your own risk. Remember this contracts are still under development and they have not gone through any audit or security review whatsoever.
