BitBox02 Nova: A Hardware Wallet Built for Bitcoin Self-Custody
BitBox, a Swiss crypto security company, has unveiled the BitBox02 Nova, a completely redesigned hardware wallet purpose-built for Bitcoin self-custody. The most significant upgrade over the original BitBox02 is native compatibility with iOS devices (iPhones and iPads), solving a long-standing limitation that forced Apple users to rely on software workarounds. To meet Apple's stringent requirements for native support, BitBox developed new hardware components from the ground up.
“Our customers are at the heart of every decision we make,” said Douglas Bakkum, CEO and co-founder of BitBox. “The BitBox02 Nova embodies this, delivering a cold wallet our customers are asking for, all while maintaining the uncompromising security and privacy that people have come to expect from us.”
Whisper Bluetooth: A Trust-Minimized Wireless Architecture
The BitBox02 Nova integrates a Bluetooth system called Whisper, which employs a trust-minimized architecture. Wireless communication is physically isolated on a separate microcontroller and logically segregated from the core wallet firmware. The main chip encrypts all outbound data before it ever touches the Bluetooth stack, and cryptographically verifies all inbound communication. To protect device privacy, Bluetooth uses randomized addresses to prevent tracking.
“Whisper silences potential attack vectors,” Bakkum stated. “It isolates Bluetooth function from the core system, ensures cryptographic integrity at every step, avoids remote tracking, and can be disabled by the user anytime.”
Security and Hardware Design: EAL6+ Certified Secure Chip
Security is paramount for any hardware wallet. The BitBox02 Nova uses an EAL6+ certified secure chip, a certification level that reflects a high standard of resistance to physical attacks. The device also includes a new display and increased internal memory, which are intended to accommodate potential software updates and additional features over time.
Two Versions: Bitcoin-Only vs. Multi-Coin
The BitBox02 Nova is available in two distinct versions. The first is a Bitcoin-only edition that runs a minimal firmware configuration, focusing on maximum security and simplicity. The second supports a selection of altcoins in addition to Bitcoin and includes functionality for universal two-factor authentication (U2F). Both versions retain BitBox's signature clean user interface and open-source ecosystem, managed through the BitBoxApp. Pre-orders are now open on the BitBox website.
