StreamBeam ENS

Problem Statement

This project builds on top of STREAMBEAM - on-chain donation platform for live-streamers that I built on ETH Global Prague. For users who donated more than $10 overall, we gift them a free ENS domain with their Twitch name. And as a prototype, those domains can be used in a leaderboard.

Solution

I'm using existing STREAMBEAM subgraph with donation information. First we check if user is eligible for reward. After using Twitch OAuth and EIP-712 signature we connect Twitch account with an address and generate an off-chain subdomain. Custom Offchain Resolver is deployed on Ethereum Mainnet.
