Frequently Asked Questions
What does the extension do?
It is your all-in-one Nostr identity provider: a NIP-07 signer with an encrypted key vault, a built-in Lightning wallet, and a manager for your profile (kind:0), NIP-65 relays, and NIP-51 mute list — with granular per-site permissions. One extension works across every Nostr client.
How does the extension work?
The extension provides NIP-07 signing (window.nostr) so any Nostr client can request event signing and NIP-04/NIP-44 message encryption. Your keys are stored in an AES-256-GCM encrypted vault with auto-lock, and you control which sites can access which methods.
Is my data private?
Yes. Your keys stay in an AES-256-GCM encrypted vault that only you can unlock, and they never leave your device unencrypted. You approve signing access per site and per method, so you always control what each Nostr app can do with your identity.
Which browsers are supported?
The extension works on Chrome, Brave, Edge, Opera, and Firefox. Safari support is scheduled and coming soon.
Do I need a Nostr account?
You can create a new account directly in the extension — it generates a BIP-39 seed phrase and derives your keys. You can also import an existing private key (nsec), add a watch-only account (npub), or connect a remote signer via NIP-46 bunker URL.
Can I send zaps with this extension?
Yes. The extension has a built-in Lightning wallet. You can connect your own wallet via Nostr Wallet Connect (NWC), enter your LNbits credentials, or use the quick setup to create a wallet instantly. The extension also acts as a WebLN provider, so Nostr apps can request payments seamlessly.
Is it free?
Yes, completely free and open source under the MIT license. The extension, Oracle API, and all source code are available on GitHub.
