Trezor Bridge — Secure Communication Between Your Trezor Device and Browser

What Is Trezor Bridge?

Trezor Bridge is a lightweight communication service that allows your computer's web browser to securely communicate with your Trezor hardware wallet. It acts as a background application, enabling compatible websites and web-based wallet interfaces to detect and interact with your connected Trezor device.

Rather than storing your cryptocurrency or private keys, Trezor Bridge simply facilitates secure communication between your hardware wallet and supported applications.

Why Is Trezor Bridge Important?

Modern web browsers have limited direct access to USB hardware devices. Trezor Bridge helps overcome this limitation by creating a secure connection between your browser and your Trezor hardware wallet.

Some key benefits include:

• 🔒 Secure communication with supported web applications

• ⚡ Faster and more reliable device detection

• 🖥️ Cross-platform compatibility for Windows, macOS, and Linux

• 🔄 Automatic communication between supported browser-based services and your Trezor

• 🛡️ Designed to work alongside the Trezor security model

How Trezor Bridge Works

When you connect your Trezor device to your computer:

1. Connect the hardware wallet using a USB cable.

2. Ensure Trezor Bridge is installed and running in the background.

3. Open a supported web application or wallet interface.

4. The browser communicates with Trezor Bridge.

5. Trezor Bridge securely relays requests to your hardware wallet.

6. Every sensitive action, such as signing a transaction, must still be confirmed on the Trezor device itself.

This design helps keep your private keys isolated within the hardware wallet.
