BitBox02 Bitcoin-only

Overview

The BitBox02 Bitcoin-only edition is a minimalist Swiss hardware wallet built by BitBox (formerly Shift Crypto) with a clear philosophy: strip out everything you don't need. By running firmware that supports only Bitcoin, it shrinks the codebase and attack surface compared with multi-coin devices, which is a genuine security benefit as well as a statement of focus. It's a favorite daily driver for Bitcoiners who want something simple and trustworthy.

The device is a slim USB-C stick with a touch-slider interface and a small OLED screen. Keys are held on-device behind a PIN, backed by a secure element, and transactions are confirmed on the screen. A nice touch is the included microSD-based backup: you can back up your seed straight to a card during setup, which many newcomers find less error-prone than hand-writing 24 words. The firmware is open-source, and the companion BitBoxApp is clean and approachable.

Honest caveats: it's a wired device, not air-gapped, so you connect it to a computer or phone. The touch-slider takes a little getting used to, and being Bitcoin-only means no altcoins — if you want those, choose the BitBox02 Multi edition instead. But for a buyer who wants an open-source, reduced-surface, genuinely pleasant Bitcoin wallet from a reputable Swiss maker, the BitBox02 Bitcoin-only is one of the easiest recommendations in the category.
