Before you choose

Consider

Block BitkeyTwo of three keys are needed. Recovery involves your phone, cloud storage and the service, rather than a conventional recovery phrase.

Blockstream Jade PlusThe standard firmware supports Bitcoin and Liquid. Bitcoin-only firmware is a separate option.

BitBox02 NovaOn iPhone and iPad, Bluetooth carries the data but the wallet still needs a physical power connection. You control it by touching its edges, not the screen. BitBoxApp on iPhone and iPad guides firmware updates when a compatible version is offered.
