Choose the Bitcoin-only edition if you want to use your hardware wallet only for Bitcoin. Choose the Multi edition if you need other supported cryptocurrencies or want to use the device as a security key for compatible online services.
Both BitBox and BitBox Nova are available in either edition. The firmware edition is set at the factory and cannot be changed later, so make this choice before buying.
Compare the editions
| What matters to you | Bitcoin-only | Multi |
|---|---|---|
| Bitcoin | Supported | Supported |
| Other cryptocurrencies | Not supported | Selected coins and tokens, including Litecoin, Ethereum and Cardano. Some require a compatible external wallet. |
| Security-key functionality | Not available | FIDO U2F authentication for compatible online services |
| Firmware scope | Focused on Bitcoin, with fewer features and less code | Includes support for additional assets and FIDO U2F |
FIDO U2F lets you use your BitBox as an additional security key when signing in to a service that supports it. This is separate from managing cryptocurrency.
Multi does not mean that every asset is supported or that every supported asset appears in the BitBoxApp. For example, Cardano uses a compatible external wallet such as AdaLite or NuFi. Before choosing Multi for a particular asset, check which coins, tokens and networks BitBox supports and which application you need.
The Bitcoin-only edition removes features unrelated to Bitcoin, reducing the firmware's attack surface. This does not make it immune to vulnerabilities. With either edition, you still need to verify transaction details on the device and protect your wallet backup.
Model and edition are separate choices
The model determines hardware features and device compatibility; the edition determines which firmware features are available. Within the same model, the Multi and Bitcoin-only editions share the same hardware. BitBox and BitBox Nova are different hardware models.
For example, using the BitBoxApp on an iPhone or iPad requires BitBox Nova, whether you choose Multi or Bitcoin-only. Compare the models on the official BitBox Nova product page, and check the current BitBoxApp device and operating-system requirements before buying.
Can I change editions later?
No. You cannot convert a Multi device to Bitcoin-only or a Bitcoin-only device to Multi. Updating the firmware or resetting the device does not change its edition. If you later need another edition, you need a different device.
If you already own a BitBox and want a different edition, read what to consider when moving to a different firmware edition. A Bitcoin-only device cannot manage non-Bitcoin assets from an existing wallet.
