What is Trezor Bridge?

Trezor Bridge is a software communication interface that enables your Trezor hardware wallet to interact securely with your computer browser. It acts as a middle layer between your Trezor device and supported web applications, such as Trezor Suite or third-party services. This tool is essential for users who want to use their Trezor without relying on browser extensions like Trezor Connect (especially in browsers that don't support extensions well).

Why Trezor Bridge Matters

Security and compatibility are the main reasons for using Trezor Bridge. It ensures direct and secure communication with the Trezor hardware wallet over USB without requiring any browser plugins. Since browser APIs are constantly changing and some browsers restrict direct USB communication, Trezor Bridge fills this gap by maintaining a stable, cross-browser environment.

How It Works

Once installed on your operating system (Windows, macOS, or Linux), Trezor Bridge runs silently in the background. When you connect your Trezor device and launch Trezor Suite or access Trezor-supported web apps, Bridge initiates and maintains a secure session. It handles message passing between your device and the service while ensuring end-to-end encryption.
