Nostr WoT

What does the extension do?

The Nostr WoT Extension is an all-in-one browser extension that acts as your Nostr identity provider (NIP-07 signer), Lightning wallet, and Web of Trust engine. It manages your keys in an encrypted vault, signs events for any Nostr client, handles zaps, and calculates trust scores — all from a single extension.

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 Lightning wallet work?

The extension includes a built-in Lightning wallet for sending and receiving zaps. Connect your own wallet via Nostr Wallet Connect (NWC), use an LNbits instance, or create one instantly with the quick setup option. It also provides a WebLN provider so Nostr apps can request payments directly.

Is my data private?

Yes. Your keys are stored in an AES-256-GCM encrypted vault that only you can unlock. For Web of Trust, Local mode keeps all calculations in your browser — nothing leaves your device. Remote mode only sends pubkey lookups to the Oracle (no content data). You can also self-host the Oracle.

Which browsers are supported?

The extension works on Chrome, Brave, Edge, Opera, and Firefox. Safari support is coming soon.

What are trust assertions?

Trust assertions are an upcoming feature that lets you make explicit, typed trust statements about other users — beyond just following them. For example, endorsing someone as a trusted developer or vouching for a merchant. These cryptographically signed statements create richer, contextual reputation on Nostr.

Is it free?

Yes, completely free and open source under the MIT license. The extension, SDK, Oracle, and all source code are available on GitHub.
