This repo is a fork of the OpenZeppelin contracts. The reason for the fork was to have long string support for tokenURI
on ERC721 contracts. This is required to show images on Aspect.
When OpenZeppelin support long strings TokenURIs for ERC721, we will defer the standard to OpenZeppelin and follow their standards.
Deploy /cairo-contracts/openzeppelin/token/erc721/ERC721_Mintable_Burnable_LongTokenURI.cairo
to StarkNet to have the NFTs available for trading on Aspect. Please see the Cairo documentation for more information on deploying contracts.

A library for secure smart contract development written in Cairo for StarkNet, a decentralized ZK Rollup.
This is repo contains highly experimental code. Expect rapid iteration. Do not use in production.
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.
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
nile compile
