🏗 ETHPrague Zupass: SE2 Starter Kit

TLDR: 🎥 watch the intro video here

Get started with Zupass to generate proofs & verify PCDs (Proof-Carrying Data).

In this Starter Kit you'll find an example of how to generate a proof and verify it on the backend.

• Frontend (check packages/nextjs/pages/index.tsx):
  • Using zuauth we generate a popup where you can generate a proof in your Zupass account.
  • It then sends the PCD to the backend.
• Backend (check packages/nextjs/pages/api/verify.ts):
  • Verifies the proof received from the frontend.
  • If the proof is valid, it sends 1 ETH to the connected wallet address.
