Frequently Asked Questions
What is Web of Trust?
Web of Trust measures social distance—how many 'hops' separate you from another user in the Nostr follow graph. If you follow someone, they're 1 hop away. If they follow someone else, that person is 2 hops from you. This helps filter spam and verify reputation without centralized blocklists.
How does the extension work?
The extension provides NIP-07 signing (window.nostr) so any Nostr client can request event signing and message encryption. It also provides a Web of Trust API (window.nostr.wot) for trust distance queries. Your keys are stored in an AES-256-GCM encrypted vault with auto-lock, and you control which sites can access which features.
Is my data private?
Yes. In Local mode, all calculations happen in your browser using IndexedDB—nothing leaves your device. In Remote mode, queries go to the Oracle API which sees the pubkeys you're checking but doesn't track or log them. You can also self-host the Oracle for complete control.
Which browsers are supported?
The extension works on all major browsers: Chrome, Brave, Edge, Opera, and Firefox.
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.
