In the ever-evolving world of digital assets, securing your Bitcoin is not just a priority—it’s a necessity. Enter the BitBox02 Bitcoin-only edition, a purpose-built hardware wallet designed with one mission: to safeguard your Bitcoin with maximum security and minimal complexity. Unlike multi-asset wallets that support countless altcoins, the BitBox02 focuses exclusively on Bitcoin, eliminating unnecessary code and reducing potential attack vectors.
Why Choose a Bitcoin-Only Wallet?
The core philosophy behind the BitBox02 is simplicity through specialization. By supporting Bitcoin only, the firmware is stripped down to its essentials. This minimalism translates into enhanced security—fewer features mean fewer vulnerabilities. There’s no risk of accidental exposure to insecure altcoin implementations or firmware bloat that could compromise your private keys.

Once configured as Bitcoin-only, the device cannot be reset or reprogrammed to support other cryptocurrencies. This permanent restriction ensures that your device remains immune to future software changes that might introduce risks—a critical feature for users committed to pure Bitcoin self-custody.
Transparent Security You Can Verify
Security isn’t just about features—it’s about trust through transparency. As a Swiss-based open-source security company, BitBox prioritizes verifiability and user empowerment.
The BitBox02 uses a dual-chip architecture, combining a secure element for physical protection with fully open-source firmware. This means every line of code can be audited by the community. Even more importantly, the firmware supports deterministic (reproducible) builds, allowing you to verify that the software running on your device matches the public source code exactly.
Don’t trust—verify. With BitBox02, you’re not handing over control to a black box.
This level of openness is rare in the hardware wallet space, where many competitors rely on proprietary firmware protected by NDAs. The BitBox02 puts you in full control, ensuring no backdoors or hidden functionalities exist.
Seamless Integration with the Bitcoin Ecosystem
Despite its minimalist design, the BitBox02 is far from limited. It’s built to integrate smoothly with the broader open-source Bitcoin ecosystem, supporting popular wallets and tools that empower advanced users.
Supported Wallets & Software
- BitBoxApp – Native desktop and mobile app with intuitive interface
- Electrum – Industry-standard desktop wallet
- Sparrow Wallet – Advanced UTXO control and privacy features
- Specter Desktop – Ideal for multisig setups
- Wasabi Wallet – Focused on coin mixing and privacy
Full Node Compatibility
You can connect your BitBox02 directly to your own Bitcoin full node, ensuring complete privacy and decentralization:
- Nodl
- myNode
- Umbrel
- RaspiBlitz
- ElectrumX or Electrs server
Running your own node means you’re no longer relying on third-party servers to validate transactions—your wallet validates the blockchain itself.

Advanced Features for Full Control
The BitBox02 isn’t just secure—it’s empowering. Whether you're new to Bitcoin or a seasoned user, it offers tools that put you in complete command of your funds.
Coin Control
Choose exactly which UTXOs (unspent transaction outputs) to spend. This gives you greater control over transaction fees and helps protect your privacy by avoiding unnecessary address clustering.
Tor Integration
All communication between your device and software can be routed through Tor, hiding your IP address and shielding your transaction patterns from network surveillance.
Roll Your Own Seed
Generate your own entropy using physical methods like dice rolls. The BitBox02 allows user-generated seeds without requiring external tools—perfect for those who want full control over their key generation process.

Modern Address Formats
By default, the BitBox02 uses Bech32 native SegWit (P2WPKH) addresses, which offer lower transaction fees and better scalability. It also supports:
- Wrapped SegWit (P2SH-P2WPKH)
- Taproot (P2TR) – enabling Schnorr signatures and improved privacy
Additionally, it supports Silent Payments, an emerging privacy-enhancing protocol that prevents sender tracking on-chain.

Frequently Asked Questions
Is the BitBox02 truly Bitcoin-only?
Yes. The Bitcoin-only edition runs a minimal, locked-down firmware that supports only Bitcoin. It cannot be switched to support altcoins, even if desired.
Can I use the BitBox02 with my existing node?
Absolutely. The BitBoxApp connects seamlessly to any Electrum-compatible full node, including myNode, Umbrel, and RaspiBlitz. You retain full control over your data.
What is “Anti-Klepto” protection?
Anti-Klepto is a cryptographic safeguard that prevents private key leakage during transaction signing by mitigating covert channel attacks on nonce generation—a vulnerability present in many other wallets.
Does it support multisig wallets?
Yes. The BitBox02 supports secure multisignature setups with automatic verification of co-signers, reducing the risk of phishing or malicious coordination.
How do I back up my wallet?
You can instantly back up your wallet to a microSD card during setup. Optionally, you can also write down your recovery phrase manually for additional redundancy.
Is the BitBoxApp necessary?
While not strictly required, the BitBoxApp unlocks the full potential of the device, offering coin control, Tor integration, insurance options, and seamless node connectivity.
Final Thoughts: A Wallet Built for the Future of Bitcoin
The BitBox02 Bitcoin-only edition strikes a rare balance: it's simple enough for beginners yet powerful enough for advanced users. Its commitment to open-source principles, reproducible builds, and Swiss engineering makes it one of the most trustworthy options for long-term Bitcoin storage.
