Keycard Shell is a modular hardware wallet in two parts. The Keycard is a smartcard with a certified EAL6+ secure element: it generates your private keys, stores them, and signs transactions on the chip itself — the keys never leave the card. The Shell is the open companion device, with a screen, keypad, and camera, that lets you read every transaction and approve it fully air-gapped, by scanning QR codes.
