Secure Connection

Connect Your Trezor
Device Securely

Trezor Bridge is a software component that enables secure communicationbetween your Trezor hardware wallet and your web browser.

What is Trezor Bridge?

Trezor Bridge is a communication tool that allows your Trezor hardware wallet to interact with your browser-based applications. It serves as a secure intermediary that enables Trezor Suite and other web applications to communicate with your Trezor device without requiring browser extensions.

When you connect your Trezor device to your computer, Trezor Bridge detects it and establishes a secure connection. This allows you to manage your cryptocurrency assets, sign transactions, and access all Trezor features directly through your web browser while maintaining the highest security standards.

The Bridge software runs locally on your computer as a background service, ensuring that all communication between your browser and Trezor device remains private and secure. It automatically starts when your computer boots up and requires minimal user interaction once installed.

Unlike browser extensions that can be vulnerable to certain types of attacks, Trezor Bridge provides a more robust and secure connection method. It's compatible with all major operating systems including Windows, macOS, and Linux, and works seamlessly with modern web browsers like Chrome, Firefox, Safari, and Edge.

Troubleshooting

Trezor device is not detected
First, make sure Trezor Bridge is installed and running. Check your system tray or task manager to confirm. Try unplugging and reconnecting your Trezor device. If using Linux, ensure udev rules are properly configured. Try a different USB port or cable. Restart your browser and computer if the issue persists.
Bridge won't install or start
Make sure you have administrator/root privileges when installing. On Windows, try running the installer as administrator. On macOS, check System Preferences → Security & Privacy for any blocks. On Linux, verify you have the correct package for your distribution and that all dependencies are installed. Temporarily disable antivirus software as it may interfere with installation.
Connection drops frequently
This is often caused by a faulty USB cable or port. Try using a different cable and USB port. Ensure your Trezor firmware is up to date. Check if other USB devices are causing conflicts. On laptops, make sure power saving settings aren't turning off USB ports. Disable any USB selective suspend settings in your power options.
Browser doesn't recognize the Bridge
Clear your browser cache and cookies, then restart the browser. Make sure you're using a supported browser (Chrome, Firefox, Safari, or Edge). Check that Trezor Bridge is running by visiting localhost:21325 in your browser - you should see a status page. Try reinstalling Trezor Bridge. Ensure no browser extensions are blocking the connection.
Multiple Trezor devices not working
Trezor Bridge supports multiple devices, but they should be connected one at a time for initial setup. Once initialized, you can connect multiple devices. Make sure each device has the latest firmware. Try connecting devices to different USB controllers/hubs. Check that you're using the latest version of Trezor Bridge.
Getting "Transport missing" error
This error indicates that your browser cannot communicate with Trezor Bridge. First, verify that Trezor Bridge is installed and running. Restart the Bridge service. On Windows, check Task Manager for "trezord.exe". On macOS/Linux, check if the trezord process is running. Reinstall Trezor Bridge if the issue continues. Make sure your firewall isn't blocking local connections to port 21325.

⚠️Still having issues?

If none of these solutions work, visit the official Trezor Support Center or contact Trezor support directly. Make sure to include your operating system, browser version, and Trezor Bridge version when reporting issues.

Frequently Asked Questions

Is Trezor Bridge safe to use?
Yes, Trezor Bridge is completely safe. It's an official software developed by SatoshiLabs, the creators of Trezor hardware wallets. The software is open-source, meaning its code is publicly available for security researchers to audit. It only facilitates communication between your browser and Trezor device - your private keys never leave the hardware wallet.
Do I need Trezor Bridge for Trezor Suite?
Yes, Trezor Bridge is required for the web version of Trezor Suite. However, if you're using the Trezor Suite desktop application, the Bridge functionality is built-in and you don't need to install it separately. For mobile access, use the Trezor Suite mobile app which uses different connection methods.
Can I use Trezor without Bridge?
For web-based access, Trezor Bridge is necessary. However, you can use the Trezor Suite desktop application which doesn't require Bridge as it includes the necessary communication components. Some third-party applications may also support direct USB communication without Bridge.
Does Trezor Bridge work with third-party wallets?
Yes, Trezor Bridge works with many third-party cryptocurrency wallets and applications that support Trezor hardware wallets. This includes popular wallets like MetaMask (with Trezor support enabled), MyEtherWallet, Exodus, and many others. Check with your specific wallet provider for compatibility.
How do I update Trezor Bridge?
Trezor Bridge checks for updates automatically. When a new version is available, you'll typically see a notification in Trezor Suite. You can also manually check for updates by visiting this page and downloading the latest version. Simply install the new version over the old one - no need to uninstall first.
What ports does Trezor Bridge use?
Trezor Bridge runs a local web server on port 21325 (HTTP) and port 21324 (HTTPS). These ports are used for communication between your browser and the Bridge. Make sure your firewall allows local connections on these ports. The Bridge only accepts connections from localhost for security.
Can I use multiple Trezor devices with Bridge?
Yes, Trezor Bridge supports multiple Trezor devices connected simultaneously. You can switch between them in Trezor Suite or compatible applications. Each device maintains its own separate identity and can be used independently.
Does Trezor Bridge collect any data?
No, Trezor Bridge does not collect, store, or transmit any personal data or information about your transactions. All communication happens locally on your computer. The Bridge only facilitates the connection between your browser and Trezor device without any external data collection.
Why does my antivirus flag Trezor Bridge?
Some antivirus software may flag Trezor Bridge as suspicious because it creates a local web server and communicates with USB devices. This is a false positive. Trezor Bridge is safe and digitally signed by SatoshiLabs. You can verify the digital signature and add it to your antivirus exceptions if needed.
How do I uninstall Trezor Bridge?
On Windows, use the standard "Add or Remove Programs" feature in Settings. On macOS, drag the Trezor Bridge application to the Trash and remove the launch agent from ~/Library/LaunchAgents/. On Linux, use your package manager (apt remove, rpm -e, etc.) to uninstall the package.
