Secure Your Crypto Journey with Trezor Bridge
The essential background application that establishes a secure, encrypted link between your Trezor hardware wallet and your web browser. Experience seamless management of your digital assets.
What is Trezor Bridge?
Trezor Bridge is a lightweight, background application designed by SatoshiLabs to facilitate communication between your Trezor hardware wallet and supported web browsers. It acts as a driver, creating a local bridge that allows your browser to detect and interact with your device securely.
In the past, users relied on browser extensions or plugins to manage their devices. However, as browser security standards evolved, these plugins became obsolete. Trezor Bridge was developed as a robust, standalone solution that runs independently of the browser's internal processes, ensuring a more stable and secure connection.
When you visit Trezor Suite for Web or use third-party wallets like MetaMask or MyEtherWallet, the website sends requests to a local port (typically 21325) on your computer. Trezor Bridge listens to this port, verifies the request, and passes it to your hardware wallet for authorization, ensuring your private keys never leave the device.
Secure Pathway: The Bridge filters all traffic, ensuring only authorized commands reach your device.
Why You Need Trezor Bridge
Optimized for security, speed, and reliability, the Bridge is the backbone of your hardware wallet experience.
Enhanced Security
By running as a standalone process, the Bridge minimizes the attack surface compared to browser extensions. It verifies the origin of requests, preventing malicious websites from communicating with your device without your consent.
Superior Performance
Direct communication via USB ensures faster data transmission. Signing transactions, loading accounts, and verifying addresses happens almost instantly, providing a smooth user experience.
Broad Compatibility
Whether you use Chrome, Firefox, Brave, or Edge, Trezor Bridge provides a universal standard. It also enables compatibility with a wide range of third-party DeFi apps and wallets.
Background Operation
Once installed, it runs silently in the background. You don't need to open it every time you want to use your wallet. It automatically starts with your system and is ready when you are.
How to Install Trezor Bridge
Follow these simple steps to get your device connected in minutes.
Download the Installer
Navigate to the official Trezor website. Select your operating system (Windows, macOS, or Linux) from the dropdown menu. Always verify the URL to ensure you are on the genuine site.
Run the Installation
Locate the downloaded file (usually trezor-bridge-x.x.x.exe or .dmg). Double-click to run it. Follow the on-screen prompts. You may need to grant administrative privileges to allow the software to install the necessary USB drivers.
Connect Your Device
Once installation is complete, connect your Trezor device to your computer using the USB cable. The Bridge should automatically detect the device. You don't need to launch the Bridge application manually; it runs as a service.
Verify Connection
Open your browser and go to Trezor Suite for Web. If the Bridge is working correctly, you will see your device listed. If prompted, allow the browser to communicate with the Bridge.
Windows
Supported on Windows 10 and later. Requires admin rights for driver installation.
macOS
Supported on macOS 10.15 and later. Supports both Intel and Apple Silicon chips.
Linux
Available as DEB and RPM packages. Udev rules may need manual configuration on some distros.
Troubleshooting Common Issues
Device Not Detected
If your device isn't showing up, try using a different USB cable or port. Ensure you are not using a USB hub, as they can sometimes cause connection drops. Restarting the Bridge process via Task Manager (Windows) or Activity Monitor (macOS) often resolves this.
"Trezor Bridge is not running" Error
This error appears if the background service stopped. You can manually start it by searching for "Trezor Bridge" in your applications. Also, check if your antivirus or firewall is blocking the connection to 127.0.0.1:21325.
Browser Compatibility
Ensure your browser is up to date. Clear your browser cache and cookies if the connection persists. Incognito mode can sometimes help isolate extension conflicts that might be interfering with the Bridge.
Reinstalling Drivers
On Windows, you may need to reinstall the USB drivers. Go to Device Manager, find the Trezor device, uninstall it, and then unplug and replug the device to trigger a fresh driver installation.
