Coinkite launched the Coldcard MK5 on March 10, 2026, marking the company's first hardware revision to the MK line since the MK4 arrived in 2022. According to reports from Coinkite, the device features a 1.54-inch Gorilla Glass display that is roughly 30 percent larger than the previous MK4 panel, providing enhanced visibility and legibility. The wallet retains the MK4's dual secure element architecture from two different chip vendors, keeping private keys fully air-gapped while maintaining the same security standards that have been relied upon for years. The device also introduces a removable button-and-screen cover that snaps in from the rear, exposing the USB-C power input and adding an optional protective layer for users who carry the wallet between locations rather than leaving it in fixed storage.
The MK5 introduces redesigned tactile buttons that are nearly flush with the chassis, replacing the indented buttons of the MK4 that required users to press into recesses. As reported by Coinkite, these new keys deliver firm tactile click feedback without the awkward finger positioning of the previous model. The device features a re-engineered chassis that flattens the screen and keyboard into a single rounded rectangle, creating a more streamlined design. The wallet's transparent case allows users to visually inspect the device's internals for hardware implants, a feature Coinkite emphasizes as a physical security advantage over opaque designs. These design improvements work together to provide a smoother and more intuitive user experience, making it easier to navigate and reducing the risk of errors during transactions.
The MK5 introduces refined near-field communication support that targets smoother air-gapped transaction signing workflows on the underlying blockchain. The new NFC stack complements existing microSD and QR-based PSBT flows, while interface elements borrowed from the Coldcard Q give the MK5 a more polished navigation feel. According to NVK, co-founder of Coinkite, the MK5 represents a reimagining of the user experience while preserving rock-solid security standards. The device continues to run the same open-source firmware that has been audited by the Bitcoin community for years and remains designed exclusively for Bitcoin, aligning with Coinkite's Bitcoin-only product philosophy. The enhanced security features include dual secure element security that provides an additional layer of protection for users' Bitcoin holdings, giving them peace of mind in the face of potential threats.
The Coldcard MK5 is available through Coinkite's official store in multiple colours, including limited orange and glow-in-the-dark variants, with pricing at $167 plus shipping. The device is shipping across multiple color and finish options, including the recognizable transparent cypherpunk aesthetic that has made the Coldcard family a recognizable fixture in self-custody circles for nearly a decade. For users debating cold-storage tooling during market drawdowns, the launch underscores how hardware-wallet competition continues to evolve around security primitives rather than convenience trade-offs alone, positioning the MK5 as a self-custody upgrade path aimed squarely at long-term holders rather than active traders. The packaging includes tamper-proof security bags with unique device numbers and flash memory codes, adding an extra layer of security verification for users.
