Coinkite introduces the COLDCARD Mk5, the latest generation of the most trusted Bitcoin signing device. Building on the Mk4's security foundation, the Mk5 continues Coinkite's tradition of iterating on hardware security for Bitcoin self-custody.
Since the original COLDCARD debuted in December 2017, Coinkite has shipped five generations of the device — each one raising the bar for what a Bitcoin hardware wallet should be.
