BitBox vs Keystone: USB simplicity or air-gapped QR signing

BitBox is a Swiss-made hardware wallet line from Shift Crypto AG, with BitBox02 and BitBox02 Nova models, Bitcoin-only and Multi editions, and the BitBoxApp. Keystone is an air-gapped hardware wallet from Yanssie HK Limited. Its Keystone 3 Pro uses QR codes and microSD cards for signing, rather than a direct network connection.

The main split is transaction flow. BitBox02 uses USB, while BitBox02 Nova also supports Bluetooth on iPhone and iPad. Keystone uses a 4-inch touchscreen, three secure-element chips and fingerprint verification. Asset coverage differs sharply: BitBox lists Bitcoin and Ethereum, while Keystone's multi-coin firmware supports more than 5,500 assets, with availability varying by wallet integration. Keystone 3 Pro is listed at a $149 sale price and $183.90 regular price.

Quick verdict

The deciding difference is how each device connects to signing software. BitBox keeps the workflow in the BitBoxApp, with USB on both current models and Bluetooth on BitBox02 Nova for iPhone and iPad. Keystone keeps signing air-gapped through QR codes or microSD, which adds transaction steps but keeps the device away from a network connection. Both support self-custody. BitBox has fully open-source firmware and app code, a Census Labs firmware audit, and a dual-chip design. Keystone has three secure elements and a Keylabs audit completed in November 2023. BitBox's July 2026 Multi-edition signing issue required firmware 9.26.3.

Choose BitBox if fully open-source firmware and app code, microSD backups, USB access, a Bitcoin-only edition or native iPhone and iPad support matter more than broad asset coverage. Its BitBoxApp also includes a Lightning wallet. The device line is designed for self-custody, with 12 or 24 recovery words and BIP39 passphrases.

Choose Keystone if air-gapped QR signing, a 4-inch touchscreen, three secure elements or support for more than 5,500 assets are the deciding features. Keystone also supports up to three recovery phrases, multisignature wallets and more than 45 integrated software wallets. Its listed Keystone 3 Pro price is $149 on sale and $183.90 regularly.
