Trezor Bridge - Seamless Communication Between Your Trezor and Browser

Trezor Bridge is the secure communication interface that connects your Trezor hardware wallet with your browser. Learn how to install, use, and troubleshoot Trezor Bridge for safe and uninterrupted crypto management.

What is Trezor Bridge?

Trezor Bridge is a lightweight background software that facilitates secure communication between your Trezor hardware wallet and compatible web browsers like Chrome, Firefox, or Edge. Acting as a bridge between your offline wallet and online applications (like Trezor Suite Web or third-party platforms), it ensures seamless data transmission without compromising security.

This essential tool replaces outdated methods like the Trezor Chrome extension or U2F protocol, offering improved compatibility, better performance, and an overall smoother user experience.

Why Do You Need Trezor Bridge?

If you’re using a Trezor Model One or Trezor Model T and prefer to access your wallet through Trezor Suite Web or third-party DApps (decentralized applications), Trezor Bridge is essential. It enables your browser to:

• Detect and communicate with the connected Trezor device
• Verify and sign transactions securely
• Access wallet balances, addresses, and more
• Interact with decentralized exchanges or DeFi apps via WebUSB or Trezor Connect

Without Trezor Bridge, your hardware wallet cannot communicate properly with online interfaces unless you're using the Trezor Suite desktop app, which already contains integrated bridge functionality.

How to Download and Install Trezor Bridge

Setting up Trezor Bridge is simple and fast. Follow these steps:

1. Visit the Official Trezor Bridge Page: Navigate to the official download page: https://trezor.io/bridge
2. Download for Your Operating System: Trezor Bridge is available for Windows, macOS, and Linux. Choose the version that matches your system.
3. Install the Application: Follow the on-screen instructions to complete the installation. The software will run silently in the background and auto-start with your OS.
4. Connect Your Trezor Device: Once Trezor Bridge is installed, connect your Trezor wallet via USB and open Trezor Suite Web. The connection should be automatic.

Trezor Bridge vs. Trezor Suite Desktop

If you're using Trezor Suite Desktop, you don't need to install Trezor Bridge separately—it's already built in. However, for web-based access via a browser or third-party services, Trezor Bridge is mandatory.
