Coinkite announces the COLDCARD Mk3, a major hardware upgrade to the Bitcoin-only signing device. The Mk3 introduced a second secure element for additional protection, making it significantly harder to compromise the device's private key storage.
The Mk3 cemented COLDCARD's reputation as the most security-focused Bitcoin hardware wallet on the market. Its air-gapped design, PSBT support, and duress PIN features set the standard that other hardware wallets would try to match.
Disclosure: Coinkite Inc. is the maker of this product and the publisher of this site.
