Trezor Bridge® | Secure Connectivity for Your Trezor Wallet

Trezor Bridge® is the secure communication tool that connects your Trezor hardware wallet to supported web browsers. Learn how it works, its benefits, and how to install it safely.

What is Trezor Bridge?

Trezor Bridge is a software application developed by SatoshiLabs that enables direct communication between your Trezor hardware wallet and your computer’s web browser. Acting as a secure middleware, Trezor Bridge allows you to use web-based interfaces—like the Trezor Suite or third-party wallet integrations—seamlessly and safely, without requiring browser extensions.

Unlike browser plugins that may become deprecated or blocked, Trezor Bridge offers stable and secure performance, supporting modern browsers like Chrome, Firefox, and Edge. Whether you're sending crypto, verifying transactions, or managing your portfolio, Trezor Bridge ensures every interaction between your device and browser remains encrypted and authentic.

Why Use Trezor Bridge?

Trezor Bridge was created to replace the older Chrome Extension previously used by Trezor devices. It provides a more secure and consistent experience across multiple platforms. Here are some key reasons to use it:

• Enhanced Security: Trezor Bridge ensures encrypted, direct device-to-browser communication.
• Cross-Browser Compatibility: Unlike browser extensions, it works across all major browsers.
• Regular Updates: Maintained by SatoshiLabs, it receives regular improvements and patches.
• User-Friendly Experience: No more worrying about outdated extensions—just install it once, and it runs in the background.

How Trezor Bridge Works

When you connect your Trezor hardware wallet to your PC via USB and access a Trezor-supported web interface, the browser communicates with your device using Trezor Bridge as the intermediary. This process happens locally on your computer, keeping your private keys isolated and never exposed to the internet.

Trezor Bridge uses WebSocket-based communication to link the browser to the hardware wallet. Once installed, it runs in the background automatically every time your computer starts up.

Installing Trezor Bridge

Setting up Trezor Bridge is quick and simple:

1. Visit the Official Website: Go to Trezor.io/Bridge.
2. Download the Installer: Choose the appropriate version for your OS (Windows, macOS, Linux).
3. Install the Application: Follow the on-screen instructions.
4. Restart Your Browser: Once installed, restart your browser and connect your Trezor.

You’ll now be able to use Trezor Suite or any supported third-party service with full functionality.

Is Trezor Bridge Safe to Use?

Absolutely. Trezor Bridge is developed and signed by SatoshiLabs, the creators of Trezor, one of the most trusted names in the crypto security space. It uses strong encryption protocols and ensures your private keys never leave your Trezor device.

Always make sure to download the software from the official Trezor website to avoid phishing or tampered versions.
