Unstoppable Domains Technical Demo

" summary

A live demo shows Unstoppable Domains’ Twitter verification wiring Chainlink oracles to an Ethereum twitter verification operator smart contract that writes only the social.twitter.username field on an ERC‑721 domain record. Flow uses the Twitter API, a Chainlink external adapter, LINK via ERC‑677 transferAndCall, and oracle signatures that clients verify locally. The build posts a tweet with a verification hash, Chainlink confirms it, signs an attestation, and the contract updates the domain record — a working, permissioned on‑chain social verification.
