In the rapidly evolving cryptocurrency landscape, securing digital assets has become paramount. Three leading open-source hardware wallets stand out in 2025: Trezor, BitBox, and OneKey. Each offers unique features while maintaining complete transparency through their open-source approach.

The entire firmware and software are publicly available on GitHub, enabling community review and optimization. Trezor supports over 8,000 cryptocurrencies and provides an intuitive interface through Trezor Suite. While premium models like Safe 5 command higher prices (€169), they offer advanced features such as colored touchscreens and SD card backup options.
BitBox02: Swiss Precision
Developed by Shift Crypto in Switzerland, BitBox02 emphasizes minimalist design and security. Available in two variants:
- Bitcoin-only edition

The wallet features capacitive touch sensors, microSD backup capabilities, and seamless integration with BitBoxApp. Both firmware and companion software maintain complete transparency through open-source development. While supporting fewer cryptocurrencies than competitors, BitBox02 excels in build quality and privacy standards.
