Trezor Bridge

The essential tool for connecting your Trezor hardware wallet with your browser

What is Trezor Bridge?

Trezor Bridge is a lightweight communication software developed by SatoshiLabs that allows your Trezor hardware wallet to interact securely with your browser and web-based applications. It acts as a secure bridge between your Trezor device and web interfaces like the Trezor Suite Web or third-party wallet integrations.

Without Trezor Bridge, your browser would not be able to detect or communicate with the Trezor device directly. This makes Trezor Bridge a critical component in ensuring smooth and secure operation of your crypto wallet.

Why Do You Need Trezor Bridge?

While the Trezor Suite desktop app doesn’t require Bridge, web users rely on it for seamless access. It enables:

How Does Trezor Bridge Work?

Trezor Bridge runs silently in the background of your operating system, creating a communication tunnel between your browser and your connected hardware wallet. It listens for secure WebUSB or HID-based communication from trusted apps and relays the messages to the Trezor device.

When you open a web app that supports Trezor, Bridge enables that site to detect the wallet, request permissions, sign transactions, and access public wallet data — all while keeping your private keys safe on your device.

How to Install Trezor Bridge

Step 1: Visit the Official Website

Go to trezor.io/bridge. Always download software directly from the official Trezor site to avoid fake versions.

Step 2: Choose Your Operating System

Select from available versions: Windows, macOS, or Linux. Download the appropriate installer for your system.

Step 3: Install the Software

Run the installer and follow the on-screen instructions. Once installed, Trezor Bridge starts automatically and runs in the background.

Step 4: Connect Your Trezor

Open your browser, plug in your Trezor device, and visit suite.trezor.io/web. Trezor Bridge will enable secure communication between your device and the app.

Compatible Browsers and Apps

Trezor Bridge ensures compatibility with most modern web tools that support crypto hardware wallets. You don’t need to configure anything manually—once installed, it works automatically.

Security Considerations

Trezor Bridge is designed to operate locally. It does not connect to third-party servers, which adds another layer of privacy and security.

Common Issues and Troubleshooting

Bridge Not Detected?

Make sure the Bridge service is running in the background. Restart your computer if the problem persists. Check your browser permissions or try a different USB port.

Device Not Connecting?

Ensure the cable is functional, and try using a different one. Always approve any connection requests on the device screen.

Blocked by Antivirus or Firewall?

Add Trezor Bridge to your system’s whitelist or firewall exceptions. It is a safe, signed application directly from SatoshiLabs.
