We build sovereign signing tools—open hardware + software that keep your keys in dedicated secure elements and let you verify what you sign. Keycard is part of the Institute of Free Technology, alongside projects like Status.
Self-custody on general-purpose devices is convenient but exposed. Dedicated hardware reduces attack surface and gives focused protection.
A contactless smart-card hardware wallet and signer (BIP-32 HD), with keys stored and used inside a secure element. Open-source, NFC-first. Works with Keycard Shell.
Open by default, verifiable, modular. We ship small, auditable parts and improve them in public through docs, forums, and community feedback.
