Before you choose

Consider

ERA WalletActivate ERA with Companion on a compatible phone; firmware updates need phone NFC. Ethereum signing needs Multichain firmware.

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.

BitBox02This model cannot sign with an iPhone. BitBox02 Nova is a different model with iPhone support.
