Trezor Bridge — Official Connection Utility

What is Trezor Bridge?

Trezor Bridge is a lightweight communication tool that allows your web browser to securely interact with your Trezor hardware wallet. Developed by SatoshiLabs, it's an essential component for using the Trezor wallet interface, especially in the web version of Trezor Suite.

Without Trezor Bridge, your browser cannot detect or communicate with your Trezor device. It acts as a secure middle layer between your computer and the Trezor web application.

Why Do You Need Trezor Bridge?

Secure USB Communication: It enables the browser to detect your Trezor device via USB.
Browser Compatibility: Works with major browsers like Chrome, Firefox, Brave, and Edge.
Essential for Web Suite: Required when using Trezor Suite Web.
Alternative to WebUSB: It provides greater reliability compared to native browser APIs.

Bridge is preferred when WebUSB is unstable or unsupported. It's especially useful for Linux users and certain corporate environments.
