BitBox02 Review 2024: The Best Open Source Wallet?

Launched in 2019, the BitBox02 has a reputation as a top-tier solution, a balance between robust security and user-friendly functionality. This review delves into these claims, providing insights to help you determine if it's the ideal hardware wallet for your needs.

I have a profound appreciation for companies that adhere unwaveringly to their principles, and Bitbox exemplifies this commitment with its BitBox02. This signing device (also called: hardware wallet), the subject of our in-depth review, stands out in its refusal to compromise.

Distinguished by its complete open-source nature, the BitBox02 not only features a vendor client (also called: companion app) but also extends support to third-party wallets such as Sparrow Wallet, Electrum, and many others.

There are two versions of the BitBox02: one exclusively designed for Bitcoin and another that accommodates a broader spectrum of altcoins. For those focused solely on BTC storage, the Bitcoin-only variant proves superior. The rationale is simple – fewer cryptocurrency types mean reduced code complexity and a smaller attack surface. Therefore, your choice between the two versions should align with your specific cryptocurrency storage preferences.

The BitBox team has meticulously considered this detail to spare you from any additional import expenses. However, for those residing in the United States, Canada, or other countries outside Europe, there's a possibility of incurring import taxes. While these taxes are a minor fraction of the total value, it's essential to factor them into your considerations.

Upon opening the package, I was pleasantly surprised to find the device enclosed in a sealed vacuum bag. This packaging not only shields the BitBox02 from moisture but also safeguards against tampering. This attention to detail sets BitBox apart, making this review an intriguing journey of discovery.

Bitbox has been quite generous with the items included in the box:

  • x1 Bitbox02
  • x1 MicroSD card (8GB, by SanDisk)
  • x1 USB-C extension cable
  • x1 USB-A to USB-C adapter
  • x1 Rubber pulls
  • x1 Stickers

However, a notable exclusion is the absence of paper recovery sheets, commonly found with other brands. This is because BitBox promotes digital storage of the seed phrase using MicroSD card, facilitated by the BitBox software.

Their caution stems from a deep concern about the security risks associated with paper, where the seed might be visible to others, and the vulnerability of paper to wear and tear. Of course, from the Bitbox hardware wallet options you can still show the BIP39 mnemonic and write it down.

Shameless plug: if you still prefer a tangible backup, consider alternatives like metal seed plates. Notably, the Black Seed Ink solution stands out, offering resistance to fire, water, explosions, and the ability to discreetly stack plates for added concealment of the seed phrase.

How Does The BitBox02 Work?

BitBox02 Design 1
BitBox02 Design 1

The BitBox02 works by connecting it to the computer, just like an USB stick. It communicates with the companion app called BitBox App, which is officially mantained by BitBox and supports most of operating systems and even Android. It let's you receive, store and send Bitcoin and other supported cryptos.

However, if you still prefer not using the client vendor, the BitBox02 supports 3rd part software wallet like Sparrow Wallet, Electrum, Specter and even MyEtherwallet.

The seed (your private key) never leaves the secure element chip. For example, imagine using your BitBox on a compromised computer, let's say with a keylogger. The BitBox's threat model acknowledges the potential compromise of your computer, emphasizing a lack of trust. Consequently, all transactions, address verifications, and critical actions are securely conducted on the device's built-in screen, incorporating touch confirmation (tap, slide, and hold). Crucial inputs such as passwords and PINs are entered directly on the device, circumventing reliance on the BitBoxApp (or whatever 3rd party apps your are using) for enhanced security.

This hardware wallet employs a dual-chip security architecture, featuring a microcontroller and a secure ATECC608B chip. The microcontroller enables the execution of open-source security code, sourced from reputable repositories, while the ATECC608B enhances wallet access security.

Wallet seed storage involves three secrets, distributed between the microcontroller and the secure chip, necessitating multiple factors for access. The BitBox02 embraces open-source principles, transparently sharing firmware, BitBoxApp, and hardware details. A secure bootloader enforces firmware integrity, accepting only signed firmware from Shift Crypto. An authenticity check ensures the device's genuineness, further fortified by physical protection measures like epoxy potting and breaking pins.

The device facilitates instant microSD card backup, allowing secure seed storage without vulnerability to visual surveillance. Security audits by Census Labs and third-party bug bounty programs fortify the firmware's resilience. Privacy features include encrypted USB end-to-end communication and non-storage of transaction data on servers.

Other advanced features include secure multisig, displaying firmware hash before boot, and user-driven entropy for seed generation. The BitBox02 has also an anti-klepto protection against covert channel attacks, reducing attack surfaces.

You may safely remove it now. Should you wish to note down the seed phrase later, you can easily do so through the available options within the BitBox app.

Sending/Receiving Bitcoin with the BitBox02

Upon completing the backup process, you'll gain access to the BitBox app dashboard. Although its design is straightforward, it contains all the essential features for self-custody.

You can effortlessly manage receiving and sending funds, and there's even an option to purchase BTC through third-party applications (we'll delve into this in more detail later).

For customers in the United States, options like Moonpay are available for topping up the BitBox, but I advise against such fiat onramps due to their high fees. There are more cost-effective solutions in the US, such as Swan Bitcoin or Kraken.

On the other hand, in Europe, there's a noteworthy service for purchasing BTC directly from the BitBox App, which we've previously reviewed on blockdyor and found quite useful: Pocket Bitcoin.

Pocket Bitcoin is a bitcoin-only exchange that automatically converts your bank transfers into bitcoin and sends them directly to your BitBox02. It has a native integration with this hardware wallet. Further details can be found in our Pocket Bitcoin Review.

Design, Build Quality & Hardware

BitBox02 Length Measurement in cm

The BitBox02 stands out with its distinctive port, opting for a male USB Type-C, a departure from the more common female USB Type-C found in other vendors. This design choice, reminiscent of early Ledger designs, may pose a challenge for those lacking the latest Mac with this port. However, inclusivity is ensured through the provision of extenders and adapters in the box, accommodating even older desktops with Type-A ports.

BitBox02 Dimensions Comparison With A USB Stick

Regarding the device's form factor, initial impressions of its small size and the absence of physical push buttons might give it a somewhat unwieldy feel. However, upon usage, the rationale behind Bitbox's decision to exclusively incorporate capacitive sensors beneath the chassis becomes apparent. This design not only aims to make it resemble more like a USB stick but also serves the dual purpose of enhancing inconspicuousness and security. Over time, physical buttons tend to wear out after a substantial number of presses.

The integration of capacitive sensors/buttons in the BitBox02 is crucial for ensuring durability and faster usage while deterring theft or seizure. In fact, the unobtrusive design makes it unlikely for anyone to recognize it as a hardware wallet; it may be easily mistaken for a simple USB stick.

BitBox02 Weight

Concerning build quality, the solid feel of the polycarbonate chassis, slightly tinted transparent for a visually appealing touch, imparts a premium sensation to this compact and super-light device. Notably, the absence of visible screws indicates a challenge in self-repair, aligning with the device's design to discourage unauthorized attempts to open it.

The true "wow effect" lies in the capacitive buttons. These buttons transcend simple touch functionality, allowing sliding gestures for actions like confirming a transaction or sliding the finger for verifying a receiving address. The touch response is remarkably smooth and responsive, a milestone achievement for a device of its compact size.

Security & Privacy

The BitBox is definitely special when it comes to security. It encrypts the communication over USB end to end and even has a unique protection against the nonce covert channel attack, by supporting a protocol called anti-klepto.

MicroSD Backups

BitBox02 distinguishes itself by eschewing the traditional paper backup sheet in favor of using the included Micro SD card. While you still have the option to back up on paper by displaying the BIP39 mnemonic during or after setup, is this method safer than the conventional paper backup? Yes, because words on paper (or metal) can be seen by others, are more challenging to conceal, and susceptible to damage through burning or ruin.

However, a Micro SD card (Sandisk 8GB, included in the box), while easy to hide, is also prone to being lost due to its small size. While not a flawless solution, BitBox's approach demonstrates creativity and a departure from the norm.

Open Source Code & Reproducibility

The fundamental basis of the BitBox02's security lies in its open-source nature, granting users with coding proficiency the ability to examine both the open-source software on GitHub and the hardware. This transparency extends to the bill of materials, circuit board schematics, and datasheets, all accessible on the official BitBox's GitHub page.

This implies that, if you possess the skills and desire, you can even assemble your BitBox02 from scratch. All the components used for the hardware are publicly available, along with the open-source software, empowering users with the option to build their own BitBox02.

BitBox02 X-Ray
BitBox02 X-Ray

If that wasn't enough, BitBox has even released x-rays of the board powering the device.

Seed Generation

The entropy, crucial for generating random seed keys, is derived from five distinct components within the BitBox02: manufacturing, device password, host computer, microcontroller, and secure chip. Each source can only contribute randomness, not diminish it.

The fully open-source and reproducibly built firmware enables users to verify its functionality. For the most security-conscious users, a dice roll method is available, generating entropy by rolling dice according to the BitBox02 Diceware instructions provided on their website.

Seed Storage

BitBox02 Security Architecture
BitBox02 Security Architecture (Source:

The seed is initially stored in the flash memory of the BitBox02. When the device is unlocked, the seed is decrypted from the flash memory and temporarily stored in the working memory (RAM) for operational purposes.

The flash memory serves as the more persistent storage, while RAM is used for temporary operations. The secure element is involved in managing the encryption and decryption keys, adding an extra layer of security to the process.

Air gap: the great "forgotten" feature

A notable missing feature of the BitBox02 is that it does not support airgapped configurations, despite accommodating PSBTs (partially signed bitcoin transactions). This is one of the few aspects I find lacking in this device.

While the attack surface on SD cards is arguably smaller than the USB stack, the BitBox team may have a different perspective on this, and I respect their decision.

Interface & Ease Of Use

The BitBox team has taken a streamlined approach with the BitBox02 hardware wallet, shifting most settings to the accompanying app and reserving the hardware wallet for crucial actions like confirming transactions or verifying receiving addresses. This design choice empowers users to perform more tasks within the app, positioning the device as more of an extension of the application.

Compatibility & Connectivity

The BitBox02 comes in two versions: the "Universal" variant, designed to support over 1500 cryptocurrencies and ERC-20 tokens, and the "Bitcoin-only" version. We'll delve deeper into these distinctions later.

The BitBox App is compatible with Windows, Mac, Linux, and Android. You can connect it to your desktop, laptop and even your mobile Android phone. However, there is currently no iOS version due to restrictions imposed by Apple on their App Store.

BitBox02 USB Type C Port
BitBox02 USB Type C Port

The BitBox02 exclusively connects via USB cable, lacking any wireless connectivity options such as NFC or Bluetooth (and notably, it doesn't include a battery). The only additional expansion port it features is the microSD, primarily used for backup purposes or managing Partially Signed Bitcoin Transactions.

BitBox App

BitBox App Advanced Settings

The app itself is very user-friendly, presenting only essential features while allowing users to delve deeper by connecting to their own node or just using public nodes provided by BitBox for convenient plug-and-play functionality.

Despite its very small size, using the BitBox02 device is surprisingly straightforward. Reading characters on the small screen is made easy, thanks in part to the touch-sensitive buttons that facilitate verification and actions with simple taps or gestures.

The bright OLED display enhances visibility, setting it apart from other hardware wallets equipped with more clunky click buttons (yuck!). The tactile advantages provided by the touch sensors contribute to the overall usability of the device.

BitBox02 Review: Supported Coins

BitBox02 Supported Coins
BitBox02 Supported Coins

If you think there is no second best, you are probably interested in the Bitcoin-only BitBox02, which supports obviously BTC on the main chain only (Bitcoin on the Lightning Network is coming soon, too). But if you believe in other projects than the Satoshi Nakamoto one, there is a BitBox that supports altcoins too.

You need to make this choice in advance however, because there aren't two different firmwares, but two differente devices: BitBox02 Bitcoin Only Edition and BitBox 02 Multi Edition. They have the same price. The coins supported in the BitBox02 Multi Edition are:

  • Bitcoin (BTC)
  • Litecoin (LTC)
  • Cardano (ADA)
  • Ethereum (ETH)
  • ERC20 tokens on the Ethereum Network
When making your selection, take into account that the Multi Edition also includes support for FIDO U2F, a two-factor authentication method (2FA) developed by the FIDO Alliance. This feature enhances the security of your online accounts. It's important to note that the Bitcoin-only version does not support FIDO U2F.
