Install Trezor Bridge: Connect Your Device in Minutes

What is Trezor Bridge?

Trezor Bridge is a lightweight background service that enables communication between your Trezor device and supported web browsers like Chrome, Firefox, and Brave. It acts as a bridge between your Trezor hardware wallet and web-based applications such as the Trezor Suite.

Unlike the older Trezor Chrome extension, Trezor Bridge works across multiple browsers and doesn't require any browser plugins. It runs as a standalone application in the background and facilitates secure communication with your Trezor device.

Note for Advanced Users

If you prefer not to install Trezor Bridge, you can use the Trezor Suite desktop application which has built-in communication capabilities. Alternatively, advanced users can run Trezor Bridge from source or use the command-line interface.

Why is Trezor Bridge Needed?

Web browsers have security restrictions that prevent websites from directly accessing USB devices. This is an important security feature that protects users from malicious websites trying to access connected devices without permission.

Trezor Bridge solves this problem by:

Enabling Secure Communication
It creates a secure communication channel between your browser and Trezor device, allowing authorized websites to interact with your hardware wallet.
Providing Cross-Browser Support
It works with multiple browsers without requiring browser-specific extensions.
Maintaining Security
It ensures that only authorized applications can communicate with your Trezor device, protecting you from malicious websites.
Running in Background
It operates as a background service, so you don't need to manually launch it each time you want to use your Trezor.
