Introduction

This guide will serve as a way to integrate your current front end with our contracts.

These assumptions apply to all sections in this guide

• You are using a react based app (either next.js/vite/create react app)

• You are using wagmi to interact with the EVM

• You have added our NPM package containing the contracts over here

• You have an API key to use our subgraph. You can follow the guide here to create your API key.
