Many crypto wallets struggle to offer both strong security and broad usability. Users often face limitations around platform compatibility, recovery options, or transparency in managing digital assets.
This creates uncertainty, especially when wallets lack features like open source transparency, instant microSD card backup, or clear device authenticity checks. With new models entering the market, expectations around what a hardware wallet should provide are shifting.
In this full BitBox02 review, we’ll examine the long-standing models and the newly released BitBox02 Nova. From compatibility to recovery, we’ll see how these devices position themselves in the current hardware wallet space.
What is BitBox02?
- Type: Hardware (cold) wallet
- Release Year: 2019
- Models: Multi Edition, Bitcoin-only Version, BitBox02 Nova
- App Interface: BitBoxApp (Windows, macOS, Linux, Android, iOS)
The BitBox02 hardware wallet was developed by Shift Crypto AG, a Swiss-based company founded in 2015 by Douglas Bakkum, who also serves as CEO. The company focuses on open-source security products for self-custody and privacy in crypto.
Shift Crypto is privately held and has received early-stage investment, but it operates independently. It is not backed by major exchanges or large corporate entities, which aligns with its focus on user sovereignty and transparent design.
Unlike other hardware wallets emphasizing touchscreen interfaces or cloud-based integrations, the BitBox02 is designed to minimize the attack surface. The wallet’s architecture and design appeal particularly to privacy-focused users and those who prefer a straightforward experience without compromising control or safety.
It supports essential cryptocurrency wallet functions like wallet creation, transaction signing, and encrypted backup, all performed through the BitBoxApp, a companion desktop and mobile application.
BitBox02 works across all major platforms, including Windows, macOS, Linux, Android, and, with the BitBox02 Nova, iOS and iPadOS via Bluetooth and USB-C.
BitBox02 Key Features
Built with a security-first mindset and backed by rigorous engineering, the BitBox02 hardware wallet offers a range of practical features that prioritize privacy, resilience, and ease of use. Those features are:
- Dual-Chip Design: The wallet leverages a dual-chip architecture (a secure chip for storing private keys and performing cryptographic operations, and a separate microcontroller to run open-source firmware). This separation reduces vulnerability and protects against potential supply chain attacks. The BitBox02 Nova’s secure chip is upgraded to an EAL6+ certified OPTIGA™ Trust M V3, offering a higher protection standard.
- microSD Card Backup: BitBox02 includes a microSD card that enables fast, encrypted backups. This feature enhances recovery options and adds redundancy without relying solely on mnemonic seed phrases.
- Invisible Touch Sensors: The device uses capacitive touch sensors embedded along its sides for menu navigation and transaction approval. This avoids mechanical failure points and supports a sleek, futuristic design consistent across all models.
- Anti-Klepto Protocol: To defend against nonce covert channel attacks, BitBox02 implements a protocol that ensures private keys remain uncompromised, even when connected to potentially compromised computers.
- Platform Compatibility & Connectivity: The original BitBox02 uses a USB-C male connector for modern mobile phones and laptops, and includes a USB-A adapter and USB-C extension cable. The BitBox02 Nova expands this with Bluetooth Low Energy for iPhone and iPad, bringing full support to iOS and iPadOS for the first time in the product line.
BitBox02 Security Architecture
The BitBox02 uses a dual-chip design to isolate cryptographic functions from firmware execution. In the standard models, a secure chip (ATECC608B) stores private keys and performs signing, while a separate microcontroller runs the open-source firmware. This separation reduces the risk of firmware compromise and mitigates supply chain attack vectors.
With the BitBox02 Nova, the secure chip has been upgraded to an EAL6+ certified OPTIGA™ Trust M V3, offering stronger physical and cryptographic resistance in line with high-security industry standards.
All sensitive operations (key generation, signing, wallet creation) occur offline within the device. Keys are never exposed to the host computer. The wallet also implements the anti-klepto protocol, preventing compromised hosts from manipulating nonce values to exfiltrate private key material through covert channel attacks.
The firmware is open source, verified for integrity at boot, and continuously audited by independent researchers. Device authenticity is checked during the initial setup process, and all units are shipped in tamper-evident packaging.
While the original BitBox02 models only support direct physical connection via USB-C, the Nova model introduces Bluetooth Low Energy exclusively for iOS and iPadOS support. This adds mobile flexibility while maintaining the principle of explicit, user-confirmed communication.
BitBox02 Review: Supported Assets
BitBox02 is available in two core models: the Multi Edition and the Bitcoin-only Edition, each with a distinct asset focus. Both are now offered in the Nova hardware variant, which includes expanded platform support and updated components without changing core asset compatibility.
Multi Edition
The Multi Edition is designed for users managing a diversified portfolio of crypto assets, with support for widely used coins and token standards:

- Ethereum (ETH);
- Litecoin (LTC);
- Cardano (ADA);
- Chainlink (LINK);
- 1,500+ ERC-20 tokens (accessible via BitBoxApp or external wallets like MyEtherWallet or Rabby).
The Multi Edition also supports WalletConnect, enabling secure interaction with Ethereum-based DeFi platforms and DApps while storing private keys on the device.
Bitcoin-only Edition
The Bitcoin-only Edition is focused solely on Bitcoin (BTC) and is optimized for users who want reduced complexity and a minimized attack surface:
- A smaller codebase means fewer vulnerabilities.

The original and Nova hardware variants offer the same asset support within their respective editions.
BitBox02 User Experience and Interface
Users often describe the BitBox02 experience as minimalist but effective. The wallet avoids visual clutter and unnecessary complexity, focusing on core usability and secure, streamlined interaction.
The BitBoxApp provides a clean, distraction-free interface across desktop and Android, allowing for straightforward account setup, asset management, and firmware updates.
Advanced features such as custom derivation paths, coin control, and full node integration are available but kept behind optional toggles, making the app suitable for entry-level and advanced users.
The device’s navigation is handled through invisible capacitive touch sensors mounted along its edges. While this input method can feel less precise during password entry or transaction confirmation than hardware buttons, it improves physical security by eliminating observable input patterns. Feedback across forums like Reddit often notes that users adapt to the system quickly after initial use.
The desktop app is frequently praised for its consistency, stability, and lack of distractions (no pop-ups, promotions, or token integrations exist). Users particularly appreciate the ease of verifying transactions and managing microSD backups, especially in contrast to more commercialized wallet ecosystems.
