Is it right for you?

Is this the right wallet for you?

A good fit if

You prefer exchanging transactions by QR code and want a large touchscreen. You already have a compatible wallet app in mind.

Consider another model if

You want the same connection to work with every app or asset. Support depends on the app, asset and installed firmware; check the exact route before choosing.

Worth comparing

Phones and computers

Check compatibility with your phone or computer.

Check the app and connection for each device. Setup and transaction signing are confirmed separately.
