The BitBox02 Multi is the cleanest, fastest hardware wallet to set up and back up.
Engineered in Zurich by Shift Crypto, the BitBox02 eliminates the tedious 24-word handwriting process by writing an encrypted backup instantly onto an included industrial-grade microSD card. Its dual-chip architecture combines an ATECC608B secure element for physical defense with a completely open-source microcontroller. The invisible capacitive touch sensors embedded along the casing make confirming addresses fast and tactile, while BitBoxApp offers clean desktop and Android connectivity.

How BitBox02 Multi scores
Five categories, ten-point scale. Bars animate when they enter view.
What is the BitBox02?
The BitBox02 is a minimalist hardware wallet designed and manufactured in Switzerland by Shift Crypto AG. It is roughly the size of a standard USB thumb drive (weighing just 12 grams) and features a direct USB-C connector on its body.
Rather than using physical click buttons or a fragile glass screen, the BitBox02 embeds invisible capacitive touch sensors along the top and bottom edges of the casing. You interact with the device using intuitive tap, slide, and hold gestures.
Shift Crypto offers two distinct editions: the Multi Edition (which supports Bitcoin, Ethereum, Cardano, Litecoin, and all ERC-20 tokens) and the Bitcoin-only Edition (which has completely stripped firmware dedicated solely to Bitcoin, eliminating unnecessary attack surfaces).
Instant MicroSD setup in under 2 minutes
Setting up the BitBox02 is faster than any other hardware wallet on the market. Setup took exactly 1 minute and 48 seconds on our test bench stopwatch.
You insert the included SanDisk industrial microSD card into the device slot and plug the USB-C plug into your laptop or phone. BitBoxApp prompts you to set a device password using the edge touch sensors.
Instead of forcing you to write down 24 words on paper and verify them one by one, the device generates your cryptographic master seed and saves a heavily encrypted backup file directly to the microSD card in under two seconds.
You eject the microSD card, put it in the included protective case, and store it safely. For users who also want a standard paper backup, you can still view the 24 BIP-39 words anytime in the settings menu.
Security architecture: The Swiss Dual-Chip approach
The BitBox02 solves the traditional open-source dilemma using an innovative dual-chip architecture.
Many hardware wallets face a choice: either use an open-source microcontroller that is vulnerable to physical glitching attacks, or use a closed-source secure element that requires NDA secrecy. Shift Crypto combines both.
The primary controller is an open-source Microchip ATSAMD51J20A running auditable firmware. Alongside it sits an ATECC608B secure element chip. The wallet derives keys using entropy from both chips simultaneously.
Even if an attacker decaps the microcontroller, they cannot access the keys without breaking the secure element. And even if the secure element manufacturer had a backdoor, they cannot compromise the wallet because the microcontroller enforces its own cryptographic checks.
BitBoxApp: Clean, Private, and Custom Node Ready
The BitBoxApp provides a serene, ad-free desktop and Android management experience. There are no banner ads, no popups pushing high-yield yield farms, and no telemetry tracking your transactions.
Privacy-focused users can connect BitBoxApp directly to their own self-hosted Bitcoin Electrum full node (such as Umbrel, RoninDojo, or Start9) with a single paste of an onion URL.
For Ethereum and DeFi users, BitBox02 integrates smoothly with WalletConnect, MetaMask, and Rabby via the WebUSB standard, allowing seamless DeFi swaps while keeping transaction signing strictly on-device.
Daily use bench results after 40 days
Over 40 days, we processed 110 transactions across Bitcoin and Ethereum. The invisible capacitive touch sensors demonstrated zero misfires once muscle memory for the slide gesture was established.
The compact form factor makes it the most discreet cold storage device in pocket carry. The male USB-C connector plugs directly into modern MacBooks and Android phones without carrying an extra cable.
The only minor physical drawback: on computers with tightly spaced USB ports, the BitBox02 body can block an adjacent USB-C port. Shift Crypto thoughtfully includes a short USB-C extension cable in the box to solve this.
Who should buy the BitBox02?
Buy the BitBox02 if you want the highest security without the headache of writing down seed phrases. The microSD card backup is foolproof for beginners and eliminates transcription errors.
Buy the Bitcoin-only Edition if you are a Bitcoin maximalist who wants minimal attack surface firmware.
Skip it if you need iOS wireless Bluetooth compatibility (choose Ledger Nano X) or if you want an expansive color touchscreen (choose Trezor Model T).

Alternatives worth considering
Three places we'd actually send a friend if BitBox02 Multi isn't right for them.
The BitBox02 Multi is the pinnacle of minimalist Swiss cold storage engineering.
After 40 days of bench testing, the BitBox02 impressed us with its rapid setup, tactile touch sensors, and zero-nonsense software. The instant microSD card backup is the single most user-friendly backup mechanism in the hardware wallet industry.
Combined with verifiable open-source code and dual-chip tamper defense, the BitBox02 is an outstanding cold storage choice for Bitcoin and Ethereum holders alike.
Frequently asked questions
Yes. It utilizes a dual-chip architecture combining an ATECC608B secure element with an open-source microcontroller. Its firmware and software are 100% open source and independently audited.
During initial setup, the device encrypts your master seed and writes it to the included industrial microSD card in seconds. If the device is lost, insert the microSD card into a new BitBox02 to restore funds in 10 seconds.
No. BitBox02 works on Android phones via direct USB-C, and on macOS, Windows, and Linux computers. iOS does not support direct USB communication for the BitBoxApp.
The Multi Edition supports Bitcoin, Ethereum, Cardano, Litecoin, and ERC-20 tokens. The Bitcoin-only Edition features stripped firmware containing only Bitcoin code, minimizing attack surface.
