Build a Gasless NFT Mint with
summary
A demo called Stamp shows an email sign‑in that auto-creates an embedded wallet in-app, configures a Privy app ID via env, and mints an NFT on Base Sepolia while Privy covers fees via gas sponsorship. The repo wires a Privy provider, exposes auth and wallet state, then calls the React useTransaction hook with the NFT ABI and sponsor: true. Dashboard toggles for guest sponsorship and client transactions must be enabled; the mint succeeds and appears on BaseScan.
