@looksrare/contracts-libs

This repository contains a set of Solidity contracts that can be used across contracts for purposes such as verifying signatures, protecting contracts against reentrancy attacks, and a library for managing the ownership of a contract.

It also contains generic contract interfaces (for EIP/ERC) that can be used.

About this repo

Structure

It is a hybrid Hardhat repo that also requires Foundry to run Solidity tests powered by the ds-test library.

To install Foundry, please follow the instructions here.

Run tests

• Solidity tests are included in the foundry folder in the test folder.
