How to Build a Shielded Address Zcash Mobile App
summary
A step‑by‑step demo shows a React Native app built with react-native-zcash that derives a spending key, derives a view key, creates a shielded z‑address, and boots a background synchronizer (requires a checkpoint to avoid full chain sync). The app queries shielded balance and transactions, renders them, and sends a shielded tx with memo; a live send of 500000 satoshis succeeds and returns a txid. Caveats: wait for full sync before querying or sending and current ECC sync performance can be slow.
