AI translates the explanation and quiz text while preserving code and answer scoring.

A robust dApp interface models explicit states: disconnected, wrong network, ready, and transaction pending/confirmed, with reactive UI updates.

js
const APP_STATES = { DISCONNECTED: 0, WRONG_NETWORK: 1, READY: 2, PENDING: 3 };
