Messenger

Hermes in a browser tab — end-to-end encrypted DMs over Nostr, addressed by .bch name. The desktop client has the richest flavour; the web messenger meets you where you are.

Preview. The desktop messenger inside Theseus is live today — threaded chat, persistent history, address book, keyboard shortcut Ctrl+Shift+E. The web-only client (what this page becomes) is in development: BIP-39 → Nostr key derivation, BCH-name resolution via gateway, NIP-17 wrap/unwrap, WebSocket to relays, IndexedDB inbox. Everything client-side, nothing uploaded.

Two clients, one identity

Desktop (Theseus) live

  • Full crypto in-process (NIP-17, nip44 v2)
  • Persistent inbox + read-state on disk
  • Address book (local JSON + vCard import)
  • Sidebar panel, Ctrl+Shift+E shortcut
  • Vault-bind: no re-typing the mnemonic
  • Reverse-resolve pk → .bch name
Get Theseus

Web (this page) building

  • Same crypto, same identity (same wallet seed derivation)
  • BCH name resolution via public gateway
  • WebSocket to Nostr relays from the browser
  • IndexedDB inbox — survives tab close, scoped to this origin
  • No download, no install, no account
  • Mnemonic entry only — never stored in plaintext
Why Hermes

Why wait for the web client

The web messenger isn't ready yet because of three things we want to get right before shipping:

  1. Key handling in a tab. A wallet mnemonic is the most sensitive bit of data a user has. In the desktop app it lives in main-process memory; in a tab it has to survive page reloads without ever landing in plaintext anywhere. We're wiring a WebCrypto-backed non-extractable key path with the vault PIN as the gate.
  2. Resolver gateway. The desktop talks to a chipnet Fulcrum directly. A browser can't — it needs an HTTPS gateway that answers np / nr for a name. The gateway is live (navigate.st/api/dns/alice.bch) but the client-side cache + signature-verification path still has an edge case with lapsed names.
  3. Relay persistence. Desktop keeps a long-lived WebSocket to each relay. A tab doesn't, because browsers throttle background sockets. The web client needs offline queueing and a well-defined "catch-up" fetch on return — otherwise you re-open the tab and the inbox feels empty.

Until the three are solid, install Theseus for the real thing. The web client will land here when the above are green.
