What is Trezor Bridge?
Trezor Bridge is a lightweight background service that enables secure communication between your Trezor hardware wallet and supported web browsers. It acts as a secure bridge that allows your browser to interact with your Trezor device without compromising security.
Unlike browser extensions, Trezor Bridge runs as a separate application in the background, providing a more stable and secure connection. It automatically starts when needed and ensures that your Trezor device can communicate with web-based wallet interfaces like Trezor Suite.
Key Features
Enhanced Security
Trezor Bridge maintains a secure channel between your hardware wallet and browser, protecting your private keys from potential browser-based threats.
Automatic Operation
The service runs quietly in the background and automatically activates when you connect your Trezor device to access wallet services.
Cross-Platform Compatibility
Available for Windows, macOS, and Linux, ensuring a consistent experience across all major operating systems.
Minimal Resource Usage
Designed to be lightweight with minimal impact on system performance while providing essential connectivity.
Security Benefits
Trezor Bridge enhances security by creating an isolated communication channel that prevents browser extensions and potentially malicious websites from directly accessing your Trezor device. This architecture ensures that:
- Your private keys never leave the Trezor hardware wallet
- All sensitive operations are confirmed directly on the device
- Communication is encrypted end-to-end
- Browser vulnerabilities have minimal impact on wallet security
By separating the communication layer from the browser environment, Trezor Bridge significantly reduces the attack surface and protects against various web-based threats.

How Trezor Bridge Works
When you connect your Trezor device to your computer, Trezor Bridge establishes a secure local connection that web applications can use to communicate with your hardware wallet. The process involves:
- Detection of connected Trezor devices
- Establishment of encrypted communication channels
- Translation of browser requests into device commands
- Relay of device responses back to the browser
- Maintenance of connection integrity throughout your session
This architecture ensures that even if a web application is compromised, it cannot directly access your device or extract sensitive information. All critical operations still require physical confirmation on the Trezor device itself.
