A shielded stock wallet inside a mobile app.

Not a mock. Every screen is a live call: instruments and prices from /assets and /prices, a real quote from /quotes, and Shield and Unshield build transactions your wallet signs and broadcasts to Robinhood Chain testnet. The note's secret is generated in your browser and never sent anywhere.

Testnet only, on purpose: a public page that could build a mainnet transaction could cost a visitor money by accident. Switch the network in the phone and it will say so.
