Trezor Bridge

The Secure Communication Link Between Your Trezor and Browser

What is Trezor Bridge?

Trezor Bridge is a background software that allows your web browser to communicate securely with your Trezor hardware wallet. It acts as a communication layer between your device and web-based applications such as Trezor Suite (web version). Without Trezor Bridge, browsers cannot directly interact with USB hardware wallets due to security restrictions.

This tool ensures encrypted, reliable data transfer so transactions, account data, and confirmations remain secure.

Why Trezor Bridge is Important

Secure Communication

Creates a protected channel between your Trezor and browser interface.

Browser Compatibility

Works with Chrome, Firefox, Edge, and other major browsers.

Background Operation

Runs silently without interrupting your workflow.

Automatic Detection

Recognizes when a Trezor device is connected.

How to Install Trezor Bridge

  1. Visit the official Trezor website.
  2. Navigate to the Trezor Bridge download page.
  3. Select your operating system (Windows, macOS, Linux).
  4. Download and run the installer.
  5. Restart your browser after installation.
Always download Trezor Bridge from official sources to avoid malicious software.

How Trezor Bridge Works

When your Trezor wallet is plugged in, Trezor Bridge detects the device and establishes a secure communication session. When you open Trezor Suite Web, the application sends requests through the Bridge, which then relays commands to the device. Transaction approvals must still be physically confirmed on the Trezor screen, maintaining hardware-level security.
