Trezor Bridge — Starting Up™ Your Device | Trezor®

Setting up a Trezor hardware wallet requires a secure connection between your device and the software you use to manage it. Trezor Bridge was designed to provide that connection, allowing a Trezor device to communicate with Trezor Suite and supported web browsers. However, users should be aware that standalone Trezor Bridge is now deprecated and Trezor recommends removing the standalone version from computers in favor of the newer connection technology incorporated into Trezor Suite.

What Is Trezor Bridge?

Trezor Bridge was a background application created by Trezor to facilitate communication between a Trezor hardware wallet, a computer, Trezor Suite, and supported browsers. When installed, the Bridge service operated in the background so compatible web applications could communicate with the connected hardware wallet.

Historically, installing Trezor Bridge was an important part of using the browser version of Trezor Suite. Trezor's documentation confirms that Bridge acted as a transport layer between the physical device and browser-based software.

Today, however, the situation has changed. Trezor has officially deprecated the standalone Bridge and recommends uninstalling older standalone installations because they may interfere with newer releases.

Trezor Bridge and Trezor Suite

Trezor Suite is the official software environment for managing supported Trezor hardware wallets. The current desktop application incorporates the necessary device-communication functionality, while supported web browsers can use newer connection methods such as WebUSB.

If you are starting with a new Trezor today, the recommended approach is to visit the official Trezor setup page, download Trezor Suite, and follow the instructions shown for your device.

The official setup process is designed to take users from connecting the hardware wallet through device initialization and wallet setup. Trezor currently recommends the desktop Suite application for the best experience, while a browser-based option is also available.

Do You Still Need to Download Trezor Bridge?

For most users, no. Standalone Trezor Bridge has been deprecated. If you already have it installed, Trezor recommends uninstalling it, particularly if you are moving to a newer version of Trezor Suite.

This is an important distinction for users searching online for a “Trezor Bridge download.” Older tutorials may still instruct users to install Bridge before opening the web version of Trezor Suite. Those instructions may reflect an earlier version of Trezor's software ecosystem.

Instead, start with the official Trezor Suite download guide. Trezor advises downloading software from its official website or its official GitHub releases rather than from third-party download pages.

How to Start Your Trezor Device

If you have just purchased a Trezor device, the simplest route is to use the current official setup process:

1. Visit the Official Trezor Website

Open Trezor.io/Start and follow the instructions for your hardware wallet. Avoid sponsored or unofficial download links that imitate the Trezor website.

2. Install Trezor Suite

Download the current Trezor Suite application for your supported operating system. Trezor Suite is available for Windows, macOS, and Linux.

3. Connect Your Hardware Wallet

Use a suitable USB data cable to connect your Trezor device. A cable that supplies power but does not support data transfer may cause the device to appear connected without actually being detected by the software.

4. Follow the On-Screen Instructions

Trezor Suite guides you through device initialization, security checks, firmware installation, and wallet setup. Do not disconnect your device during firmware installation unless the software specifically tells you to do so.

5. Secure Your Wallet Backup

During setup, pay close attention to your wallet backup instructions. Never provide recovery information to a website, person, or support representative claiming that it is required to activate or unlock your device.

What If Trezor Suite Does Not Detect Your Device?

If your Trezor is connected but does not appear in Trezor Suite, begin with the basics. Trezor recommends checking that you are using a quality data-transfer cable and ensuring your device firmware is current. USB connections, operating-system drivers, VPNs, firewalls, and antivirus software can also affect communication.

If you previously installed standalone Trezor Bridge, check whether it is still running. Because the standalone version is deprecated, an older Bridge installation can interfere with newer software. Trezor provides operating-system-specific instructions for removing it.

For additional assistance, use the official Trezor support resources rather than relying on unofficial download or troubleshooting websites.

Trezor Bridge: An Important Transition

Trezor Bridge played an important role in the earlier Trezor ecosystem, but it is no longer the recommended standalone solution. Modern Trezor users should generally use the latest Trezor Suite and its supported device-communication methods.

If you are researching Trezor Bridge because an older guide told you to install it, first check Trezor's current documentation. The official guidance now states that standalone Bridge is deprecated and recommends removing it where appropriate.

For a new device, begin with Trezor.io/Start, use the official Trezor Suite, and follow the current setup instructions. Keeping your software current and obtaining downloads directly from Trezor are simple but important steps toward maintaining a secure hardware-wallet setup.
