Nostr Vault is a native Nostr client that ships with its own relay. Your notes, media and contact list live on a relay you run, on your phone, tablet or Mac, instead of only on someone else's server.

Which platforms does Nostr Vault run on?

iPhone and iPad via TestFlight, macOS from the GitHub releases page, and Android as a direct APK download or through Zapstore.

Is my private key safe?

Your nsec is encrypted at rest with NIP-49 (ncryptsec) and the password lives in the system Keychain. You can also keep the key off the device entirely with a NIP-46 remote signer, paired by scanning its bunker QR code.

What is the difference between the phone relay and the Mac relay?

On iPhone, iPad and Android the embedded relay keeps a full copy of your notes and pushes them out to the relays you choose. A Mac with a domain name runs the same relay 24/7 at a public address, so other people and other clients can read from it directly.

What if your notes lived with you?

Every note you post today lives on somebody else’s relay. Nostr Vault runs one on hardware you hold, mirrors your outbox, inbox, chats and Blossom media to it, and keeps your key encrypted with NIP-49 or out of the app entirely with a NIP-46 bunker. Zaps ride Nostr Wallet Connect, and your on-chain Bitcoin is derived from the same nsec.

The Nostr Vault feed menu on iPhone listing Following, Discover, Global, Popular, Media, Reels, Articles, Recipes, Live, Music and Dashboard

One app. Eleven feeds.

Everything Nostr publishes, one tap away.

Nostr is more than short notes. Nostr Vault reads every kind the network speaks and gives each one a home, so you switch between them from a single menu instead of a single firehose.

Following — the people you chose, threaded or condensed, your call.
Discover & Popular — the second hop of your follow graph, ranked by real people, not reaction spam.
Global — the whole network, behind a Web of Trust filter so it fails closed, not open.
Reels — a full-screen vertical video feed with likes, replies and zaps while you watch.
Articles — long-form posts drawn as articles, with a proper reader.
Recipes, Live & Music — zapcooking recipes, NIP-53 live streams with chat, and trending tracks from Wavlake.
Media — a grid of every photo, GIF and video from your follows, sorted by date.

What’s inside

Built like a relay. Feels like an app.

Your relay, in the app

The same battle-tested Go relay that powers the Haven CLI is compiled into the app as a static library. One process, no helpers, no server to rent. Your notes are stored on your device first and broadcast outward from there.

Keys that never sit in plaintext

Your nsec is encrypted with NIP-49 and the password lives in the system Keychain. Prefer to keep the key off the device entirely? Pair a NIP-46 remote signer by scanning its bunker QR code, on iPhone and Android.

Zaps and a Lightning wallet

Send and receive sats through Nostr Wallet Connect with a live balance, invoice amounts shown before you pay, lightning addresses and a history tab. Zap a note, a reel or a live stream without leaving it.

Your nsec is a Bitcoin wallet

Nostr Vault derives a native Taproot address from your Nostr key and can sweep it on-chain, signed with Schnorr inside the app and broadcast through Mempool. No external wallet, no extra seed.

Web of Trust, on by default

Global feeds are filtered by the trust graph of your follows, so a fresh account starts with a seeded graph instead of the raw firehose. Language filters, mute-list sync and per-account block lists round it out.

Blossom media, hosted by you

A built-in Blossom server stores your photos and videos, mirrors them to the servers you choose and signs each upload once. Paste an image into the composer and it lands on your own storage.

Notifications with no middleman

DMs, mentions, replies, zaps, reactions and reposts are generated on-device from your own relay stream. No push server, no third party, selectable sounds, and taps that open the right note.

Widgets and a real iPad layout

Vault Pulse, Feed Glance, Quick Actions, Sats, Mosaic and Lock Screen widgets on iOS and iPadOS, with home-screen widgets on Android too. On iPad the feed and relay become true columns with a draggable divider.

Native on every platform

SwiftUI on iPhone, iPad and Mac. Jetpack Compose on Android. Six accent themes, one motion vocabulary that honours Reduce Motion, a GIF keyboard in the composer, and a menu-bar status panel on the Mac.

Screens

Dark, dense, and quick.

On-chain

Your nsec is your wallet.

Nostr Vault is the first native Nostr client to derive a real on-chain Bitcoin address directly from your Nostr secp256k1 key, and let you sweep it.

Taproot from your key

Pure BIP-341 key-path Taproot (P2TR) derivation, computed in Go by btcsuite/btcd inside the embedded relay. Same private key, a new address, zero external processes.

Schnorr-signed sweeps

Fetches your UTXOs from a Mempool instance, builds a raw Taproot transaction, signs it with Schnorr via key-path spending and broadcasts it, all inside the app.

Live balance and price

The pre-sweep screen loads your spendable balance live from Mempool with a fiat equivalent from the built-in price service. No surprises before you sign.

Two ways to run it

Pocket relay, or a home on the network.

Every build carries the full relay. What changes is who can reach it.

iPhone, iPad & Android — pocket relay

Your device keeps a complete copy of your notes, media and lists, and pushes everything out to the relays you configure. Nothing on the network can reach in to read from your phone, so it is a private backup and a megaphone rather than a public address. On Android you can even swap in another on-device relay such as Citrine.

Mac + domain — full relay

Run it 24/7 on a Mac with a real URL like relay.yourdomain.com, and anyone can connect to read your notes: your own phone, your friends, other relays. Set the Mac as a relay in the mobile app and it syncs your full history once, then keeps you current. Push and pull.
