Coldcard MK4 vs Blockstream Jade Plus
Key differences
- Coldcard MK4 prioritizes maximum offline security with dual secure elements and air-gapped microSD usage, while Jade Plus uses a virtual secure element with broader connectivity.
- Blockstream Jade Plus has a larger full-color display and Bluetooth + SD card support, making it more user-friendly for mobile users; Coldcard is better suited for air-gapped workflows and technical users.
- Both cost about the same (~$169), but Coldcard is Bitcoin-only with deep multisig and PIN tricks, while Jade Plus supports Bitcoin and Liquid with a more modern, beginner-accessible design.
