Trezor Bridge & Download Guide

Introduction

The Trezor Bridge is a communication tool that allows your Trezor Hardware Wallet to connect securely with applications like Trezor Suite or supported third-party wallets. Without the Bridge, your device may not be recognized on desktop operating systems. Installing the latest version ensures stable connections, smooth firmware updates, and secure transaction signing.

What is Trezor Bridge?

Trezor Bridge is lightweight background software that acts as a translator between your Trezor device (Model One or Model T) and your operating system. It ensures:

Seamless USB communication between device and desktop app.
Secure signing of crypto transactions.
Compatibility with Chrome, Firefox, and other browsers.
Automatic updates for best performance.

Why Do You Need Trezor Bridge?

While modern browsers support WebUSB (direct device communication), Trezor Bridge provides more reliable connectivity across platforms. It is especially important if:

You use Linux or macOS with strict USB permissions.
Your browser lacks native WebUSB support.
You prefer using Trezor Suite Desktop App for maximum security.

Select the installer for your operating system (Windows, macOS, Linux).
Download the file and verify it matches the version listed on the official website.
