FAQ
What is zostr?
zostr is a public social application for the Zcash community built on the open Nostr network. It allows users to post, follow others, and send shielded ZEC payments using their .zcash name as their identity.
How does zostr handle privacy?
While posts, profiles, and follows are public, direct messages are end-to-end encrypted using NIP-17. Payments are shielded and handled by your own Zcash wallet, ensuring your funds are private. The app also states it has no ads, trackers, or analytics.
Is zostr free to use?
Yes, zostr is available for free. The application does not have ads, in-app purchases, or a token, and is developed independently.
How is my identity managed on zostr?
Your identity on zostr is your .zcash name, such as alice.zcash, which is verified across the Nostr network (NIP-05). This name serves as your recovery root, and your signing key is generated and encrypted on your device.
Can I send Zcash through zostr?
