Reseña
Bitcoin-only hardware wallet that signs PSBTs via SD card — never plugs into a network-connected machine. Open-source firmware, secure element (Microchip ATECC608A). 'Mk4' model is current; supports BIP39/BIP85, taproot, multisig. The signer pattern of choice when paired with Sparrow/Specter for multi-vendor multisig setups.
