Connect your Trezor
to your browser
Trezor Bridge is a software application that facilitates communication between your Trezor hardware wallet and your web browser. Download and install it to securely manage your cryptocurrency assets.
What is Trezor Bridge?
Trezor Bridge is a communication interface that allows your Trezor hardware wallet to interact with web-based applications, primarily the Trezor Suite and other cryptocurrency management platforms. It acts as a secure bridge between your device and your browser, ensuring that your private keys never leave the safety of your hardware wallet.
When you connect your Trezor device to your computer via USB, Trezor Bridge establishes a secure connection that enables you to send and receive cryptocurrency, manage your portfolio, and perform other wallet operations directly through your web browser.
Unlike browser extensions, Trezor Bridge runs as a standalone background service on your computer. This architecture provides enhanced security and compatibility across different browsers including Chrome, Firefox, Safari, and Edge.

Installation Guide
Follow these step-by-step instructions to install Trezor Bridge on your system.
Download the Installer
Click the download button for your operating system above. The installer file will be saved to your default downloads folder. Make sure to download from the official Trezor website to ensure authenticity.
Run the Installer
Locate the downloaded file and double-click to run it. On Windows, you may see a security warning - click "Run anyway" as this is expected for new installations. On macOS, you might need to right-click and select "Open" if you see a security message.
Follow Installation Wizard
The installation wizard will guide you through the process. Simply click "Next" or "Continue" through the prompts. The default settings are recommended for most users. The installation typically takes less than a minute to complete.
Restart Your Browser
After installation is complete, close and restart your web browser. This ensures that the browser can properly detect and communicate with Trezor Bridge. You don't need to restart your entire computer.
Connect Your Trezor
Plug your Trezor device into a USB port on your computer. Navigate to Trezor Suite or any compatible web application. The Bridge will automatically detect your device and establish a secure connection.
Verify Installation
To confirm that Trezor Bridge is running correctly, look for your device in Trezor Suite. If your device is recognized and you can access your wallet, the installation was successful. The Bridge will now run automatically in the background whenever needed.
Troubleshooting
Having issues? Here are solutions to common problems you might encounter.
Device Not Detected
First, try using a different USB cable or port. Ensure your Trezor device is properly connected and unlocked. Restart Trezor Bridge by completely closing your browser and reopening it. On Linux, you may need to add udev rules - check the official Trezor documentation for your distribution.
Bridge Not Running
Check your system tray (Windows) or menu bar (macOS) to see if Trezor Bridge is running. If not, manually launch it from your Applications folder or Start menu. You can verify it's running by visiting localhost:21325 in your browser - you should see a "Trezor Bridge" message.
Connection Timeout
This usually indicates a communication issue between the browser and Bridge. Close all browser windows completely and reopen them. Ensure no firewall or antivirus software is blocking Trezor Bridge. Try disabling browser extensions temporarily to rule out conflicts.
Installation Fails
Make sure you have administrator/root privileges on your system. Disable any antivirus software temporarily during installation. On macOS, check System Preferences → Security & Privacy to allow the installation. If problems persist, try downloading the installer again as it may have been corrupted.
Multiple Devices Issue
If you have multiple Trezor devices, make sure only one is connected at a time when trying to access your wallet. The Bridge can handle multiple devices, but some applications may only work with one device at a time. Disconnect other hardware wallets that might interfere.
Updates Not Installing
Manually uninstall the current version of Trezor Bridge before installing the update. On Windows, use "Add or Remove Programs". On macOS, drag Trezor Bridge from Applications to Trash. On Linux, use your package manager. Then download and install the latest version.

Frequently Asked Questions
Is Trezor Bridge required to use my Trezor device?
Yes, Trezor Bridge is required for using Trezor devices with web-based applications like Trezor Suite. It provides the communication layer between your hardware wallet and your browser. Without it, your browser cannot interact with your Trezor device.
Is Trezor Bridge safe to install?
Absolutely. Trezor Bridge is developed by SatoshiLabs, the makers of Trezor hardware wallets. The software is open source, meaning its code is publicly available for review and audit. It has been thoroughly tested and is used by hundreds of thousands of Trezor users worldwide. Always download from the official Trezor website to ensure authenticity.
Does Trezor Bridge work with all browsers?
Yes, Trezor Bridge is designed to work with all modern web browsers including Google Chrome, Mozilla Firefox, Safari, Microsoft Edge, Opera, and Brave. Because it runs as a standalone application rather than a browser extension, it provides consistent functionality across all browsers.
Do I need to keep Trezor Bridge running all the time?
No, you don't need to manually manage Trezor Bridge. It's designed to run automatically in the background when needed. Once installed, it will start automatically when you connect your Trezor device and try to access it through your browser. It uses minimal system resources when idle.
How do I update Trezor Bridge?
Trezor Bridge will notify you when updates are available. You can also check for updates manually by visiting the Trezor website. To update, simply download and run the latest installer - it will automatically replace the old version. You don't need to uninstall the previous version first unless you encounter installation issues.
Can I use Trezor Bridge with multiple Trezor devices?
Yes, Trezor Bridge supports multiple Trezor devices. However, when using web applications, you typically work with one device at a time. You can switch between devices by disconnecting one and connecting another. The Bridge will automatically detect whichever device is currently connected.
Does Trezor Bridge collect any personal data?
No, Trezor Bridge does not collect, store, or transmit any personal information or transaction data. It simply facilitates communication between your Trezor device and your browser. All sensitive operations happen on your Trezor device itself, where your private keys are stored securely and never exposed.
What should I do if my antivirus flags Trezor Bridge?
Some antivirus software may flag Trezor Bridge as suspicious because it's a communication tool that accesses USB devices. This is a false positive. You can safely add Trezor Bridge to your antivirus exceptions list. Always ensure you downloaded the software from the official Trezor website.
Can I use Trezor without installing Bridge?
For most web-based applications, no - Trezor Bridge is required. However, the Trezor Suite desktop application includes Bridge functionality built-in, so if you use the desktop version of Trezor Suite, you don't need to install Bridge separately. The desktop app is a standalone solution.
How do I uninstall Trezor Bridge?
On Windows, go to "Add or Remove Programs" in Settings, find Trezor Bridge, and click Uninstall. On macOS, open the Applications folder, find Trezor Bridge, and drag it to the Trash. On Linux, use your distribution's package manager to remove it. After uninstalling, you may need to restart your computer.
