The essential communication layer that securely connects your Trezor hardware wallet to browser-based and desktop applications.
Trezor Bridge is a lightweight background service developed to enable seamless and secure communication between Trezor hardware wallets and web-based applications such as Trezor Suite. It acts as a trusted intermediary that allows browsers to interact with the hardware device without exposing sensitive cryptographic data.
As modern browsers continue to tighten security restrictions, direct hardware communication has become increasingly complex. Trezor Bridge solves this challenge by providing a standardized and secure connection layer that works reliably across operating systems.
Back to TopThe primary role of Trezor Bridge is to ensure that users can safely interact with their hardware wallet when using browser-based interfaces. Without Trezor Bridge, web applications would face limitations in detecting and communicating with USB-connected devices.
Trezor Bridge ensures:
• Reliable device detection
• Secure message transport
• Compatibility across browsers
• A smooth user experience
This makes Trezor Bridge a critical component of the overall Trezor ecosystem, especially for users who prefer accessing their wallets through web interfaces.
Back to TopTrezor Bridge operates as a background service installed on the user’s computer. Once installed, it listens for requests from supported web applications and forwards them securely to the connected Trezor device.
The software is designed to work consistently across Windows, macOS, and Linux. This cross-platform compatibility ensures that users receive the same reliable experience regardless of their operating system.
Trezor Bridge uses standardized communication protocols that allow authorized applications to interact with the hardware wallet while preventing unauthorized access.
Back to TopSecurity is at the heart of Trezor Bridge’s design. The software never accesses or stores private keys. Instead, it merely transfers messages between the application and the hardware wallet, where all sensitive operations are securely executed.
By isolating cryptographic operations within the hardware device, Trezor Bridge significantly reduces the attack surface and protects users from malware and phishing attempts.
