What Nostr WoT does
Nostr WoT is an open-source software project building trust, identity, and payment infrastructure for the Nostr decentralized social protocol. Founded in 2026 and operated as a private, MIT-licensed project under founder Leon Acosta, the company distributes a browser extension that combines three previously fragmented functions into a single product: a NIP-07 identity provider with AES-256-GCM encrypted key storage, a Web of Trust scoring engine that filters content by social-graph distance, and a built-in Lightning wallet supporting NWC, LNbits, WebLN, and Lightning Addresses. Supporting infrastructure includes the WoT Oracle, a Rust-based backend that indexes the Nostr follow graph (1.25M+ pubkeys, 8.5M+ relationships) and serves trust queries at sub-millisecond cached latency and 10,000+ req/s throughput via bidirectional BFS pathfinding, plus a TypeScript/React SDK on npm for developers integrating WoT into Nostr applications.
The product suite is targeted at three horizontal segments: Nostr end-users (identity, signing, spam filtering), Bitcoin/Lightning users (zaps, Lightning Address), and Nostr app developers (SDK, headless UI, trust module). Distribution is fully product-led and community-led via browser extension stores (Chrome, Brave, Edge, Opera, Firefox), npm, GitHub, Docker self-hosting, and embeddable Nostr Widgets for SEO-driven inbound.
The business model is non-commercial: all products are free under the MIT License, the Oracle public instance is rate-limited but free, and no paid tiers or licensing fees exist. The project is not venture-backed and is funded through community contributions. Named integration references include Mapping Bitcoin (24,000+ merchant venues using WoT for trust-based reviews) and Obelisk (community-focused Nostr client). Planned roadmap items — Trust Assertions (typed endorsements) and Services Integration (trusted merchant discovery) — signal expansion of the trust layer beyond follow-graph distance into verifiable reputation and real-world commerce.

Nostr WoT competitors and assessment
Company assessmentBroad incumbents
- Coracle: Coracle is a Nostr web client with WebLN and trust badge support; comparable to Nostr WoT as a downstream integration point and as a peer that also exposes trust-based filtering.
- Primal: Primal is a cross-platform Nostr client supporting WebLN payments and trust badges; it overlaps with Nostr WoT's wallet and trust surfaces while serving a much broader consumer audience.
- Snort (Pleb Lab): Snort is a web-based Nostr client supporting WebLN and trust badges; it is a comparable broad incumbent that consumes signer/wallet functionality similar to what Nostr WoT exposes.
- Damus: Damus is a leading iOS Nostr client that integrates NIP-07 and Lightning payments; it is a broad incumbent in the Nostr ecosystem and a downstream consumer/partner of signer and wallet functionality that Nostr WoT provides.
- Amethyst (Vitor Pamplona): Amethyst is a major Android Nostr client that handles signing and Lightning natively; it is a comparable broad incumbent that integrates wallet and identity flows alongside its own social product.
Emerging players
- Mutiny Wallet: Mutiny is a self-custodial Lightning wallet supporting Nostr Wallet Connect; it overlaps with Nostr WoT's wallet layer as an emerging player that users can plug into the extension via NWC.
- KeyChat / Another.chat (Nostr DM clients): KeyChat and similar NIP-04/NIP-44 encrypted DM clients consume the same identity and encryption stack Nostr WoT provides, making them adjacent emerging players in the Nostr identity and messaging layer.
Direct peers
- nos2x (fiatjaf): nos2x is one of the original NIP-07 Nostr browser extensions for event signing; it competes head-to-head with Nostr WoT on the identity/signer layer and historically defined the category Nostr WoT is trying to expand.
- Alby (getalby.com): Alby's browser extension provides NIP-07 signing, a WebLN provider and a built-in Lightning wallet, directly overlapping with Nostr WoT's identity + wallet + Lightning bundle and competing for the same Nostr user install base.
Others
- LNbits: LNbits is open-source Lightning wallet infrastructure that Nostr WoT integrates; it is an ecosystem enabler/provider rather than a direct competitor, but its custodial capabilities overlap with Nostr WoT's Quick Setup wallet flow.
