Ethereum Contracts

This project is an attempt to create a more efficient implementation of the common interface IERC721 compared to Open Zeppelin's implementation.

What's Inside

• Forge: compile, test, fuzz, format, and deploy smart contracts
• Forge Std: collection of helpful contracts and utilities for testing

Installation

Foundry typically uses git submodules to manage dependencies, but this template uses Node.js packages because submodules don't scale.

This is how to install dependencies:

1. Install the dependency using your preferred package manager, e.g. yarn install dependency-name
   • Use this syntax to install from GitHub: yarn install github:username/repo-name
2. Add a remapping for the dependency in remappings.txt, e.g. dependency-name=node_modules/dependency-name
