The app offers LNURL addresses, Nostr Wallet Connect, multiple-wallet support, a built-in store, a point-of-sale app, and a standalone Spark recovery tool. Its built-in store integrates The Bitcoin Company, PPQ AI, nadanada, and SMS4Sats for purchases using sats. Current product features include contact-based payments, payment pools, Bitcoin gift links, stablecoin integration, USDB savings, and human-readable payment addresses.
