We are a compact crew of cryptographers, hardware engineers, and self-custody advocates united by a shared alarm at how casually the world treats private keys. Every design decision passes through a secure review that asks, “Does this make a bitcoin holder genuinely safer, or just more comfortable?” Our lab in London runs like a watchmaker’s workshop: slow, precise, and allergic to shortcuts that could weaken the hardware wallet barrier. We hire carefully, valuing proven side‑channel research over generic résumés, and we personally test every crypto feature on our own life savings before it reaches you. Team members publish under their real names, because accountability is the only secure foundation for cold storage.
