Nostr Onchain
Device feature

Bunker Bridge

Remote signing without remote trust. The Pocket Signer serves a bridge page that speaks NIP-46 — copy the bunker link into any bunker-aware client (on your phone, another computer, anywhere) and signing requests travel over Nostr relays to the device, where each one still requires a physical tap.
