Quick Setup

This guide will teach you how to create a social application where users can create on-chain badges that can be linked to an event. Once users have set up their profiles, they will be able to create badges for an event and attendees will have the ability to collect them by attending that event.

This is a basic example with the sole purpose of going over core features and highlighting how easy to implement them. Later on you can extrapolate and get creative with your project to create different use cases that would truly make your app stand out.
