Trézor Bridge | Official Tool for Wallet Access

Welcome to the definitive, official guide for Trézor Bridge®, the trusted software that securely connects your Trézor hardware wallet to supported browsers and applications. This guide explains what Bridge is, how it works, how to install it safely, and tips for troubleshooting and secure use.

1. What Is Trézor Bridge?

Trézor Bridge® is an official background application that establishes a secure communication channel between your Trézor hardware wallet and internet applications (including the official web wallet and suite). This “bridge” is necessary because most browsers cannot directly access USB devices due to security restrictions. :contentReference[oaicite:0]{index=0}

1.1 Why You Need Trézor Bridge

• Enables secure communication via USB between your device and your browser. :contentReference[oaicite:1]{index=1}
• Improves compatibility with browsers like Chrome, Firefox, Edge, and Brave. :contentReference[oaicite:2]{index=2}
• Acts as a secure local server, preventing unauthorized applications from accessing your device. :contentReference[oaicite:3]{index=3}

3. How Trézor Bridge Works

3.1 Communication Flow

When your browser needs to interact with your Trezor wallet, it sends a request to the local Bridge service. Bridge then securely relays that request through USB to your device. Once the device processes it (for example, signing a transaction), Bridge forwards the response back to the browser. :contentReference[oaicite:4]{index=4}

Typical Sequence:

1. Your browser or app contacts Bridge on localhost.
2. Bridge authenticates the request and relays it over USB.
3. Your Trezor device processes the command.
4. Bridge returns the signed data or status back to the app/browser.
