A keychain-sized hardware signer that renders Nostr events and Bitcoin transactions on-device before producing BIP-340 signatures after a physical tap.

Landing page captured for the 2026-08-21 issue.

Why it surfaced

Pocket Signer serves its own local pages over USB-C, supports Taproot PSBT review, and links to its firmware source. The page is unusually candid about its limits: PIN protection is still on the roadmap, and users are told to begin with testnet or small amounts.
