Bitcoin hardware wallet manufacturer Coinkite has unveiled the Coldcard Q1, a premium signing device designed for advanced users who demand air-gapped security and ease of use. The new wallet incorporates a full QWERTY keyboard and a built-in QR code scanner with LED illumination, while retaining the same security architecture as the widely trusted Coldcard Mk4.
Key Features of Coldcard Q1
The Coldcard Q1 is a battery-powered, standalone device that operates without a desktop connection. Its 320×240 pixel LCD screen is approximately four times larger than the Mk4’s display, providing clearer transaction details. The QWERTY keyboard simplifies the entry of BIP-39 passphrases, and the QR scanner allows fast, air-gapped data exchange. Two MicroSD slots and near-field communication (NFC) enable flexible data import/export. Notably, USB and NFC data can be irreversibly blocked via a physical switch, eliminating side-channel risks.
Coinkite emphasizes that all Mk4 features are present on the Q1, but many are more accessible due to dedicated keys. For instance, a dedicated 'QR' key instantly displays any value as a scannable QR code, while the 'NFC' key triggers context-aware NFC transfers. The device runs on three AAA batteries, ensuring true offline resilience.
Pricing and Competitive Landscape
The Coldcard Q1 is priced at $199.99 per unit, compared to $147.94 for the Mk4. Customers paying with Bitcoin receive a 5% discount using a promo code displayed on Coinkite’s website. The launch comes amid a wave of new hardware wallets: Ledger introduced the Stax in December 2022, designed by iPod creator Tony Fadell, and in January 2023, 1inch Network announced its own hardware wallet. The race to innovate in self-custody solutions is intensifying, and Coinkite’s Q1 positions itself as a high-end option for Bitcoin maximalists who prioritize security and offline operation. With its unique keyboard and scanner, the Q1 aims to bridge the gap between cold storage and user-friendly transaction signing.
