Trezor Bridge is the secure communication layer that enables your Trezor hardware wallet to interact safely with web browsers and cryptocurrency applications.
Trezor Bridge is a background service that facilitates secure communication between your Trezor hardware wallet and web applications. It acts as a crucial security layer, ensuring that your private keys never leave your hardware device while enabling seamless interaction with web-based cryptocurrency services.
Establishes a protected channel between your Trezor device and web browsers, preventing interception or manipulation of sensitive data.
Enables Trezor hardware wallets to work seamlessly with web-based applications and services without compromising security.
Prevents malicious software from intercepting or modifying communications between your device and cryptocurrency applications.
While Trezor Bridge was previously a standalone application, its functionality is now integrated directly into Trezor Suite - the official desktop application for managing Trezor devices. This integration provides a more streamlined and secure user experience.
Trezor Bridge implements a sophisticated security architecture that maintains the fundamental principle of hardware wallet security: private keys never leave the device.
Trezor Bridge runs a local HTTP server that handles communication between web applications and the connected Trezor device, avoiding browser security limitations.
All communication between the browser and Trezor device is encrypted and validated to prevent tampering or eavesdropping by malicious software.
Each message requires physical verification on the Trezor device screen, ensuring users can review and approve every transaction.
Trezor Bridge has evolved significantly since its initial release, with the current implementation offering improved security and user experience.
Originally released as a separate application that needed to be installed alongside web browsers to enable Trezor connectivity.
Bridge functionality was gradually integrated into Trezor Suite while maintaining backward compatibility with the standalone version.
Modern implementation where Bridge is built directly into Trezor Suite, eliminating the need for separate installation and maintenance.
If you have the legacy standalone Trezor Bridge installed, it's recommended to uninstall it and use Trezor Suite instead. The integrated version provides better security, automatic updates, and a more streamlined user experience.
The integrated Trezor Bridge within Trezor Suite maintains broad compatibility across operating systems and Trezor device models.
Full support for Windows 10 and Windows 11 with automatic driver installation and update capabilities.
Compatible with macOS 10.14 (Mojave) and later versions, optimized for both Intel and Apple Silicon architectures.
Available for most popular Linux distributions including Ubuntu, Fedora, and Debian with udev rules configuration.
Full compatibility with the flagship Trezor Model T, including all advanced features and touchscreen interactions.
Complete support for the original Trezor Model One with all its functionality and security features.
Full integration with the latest Trezor Safe 3, including its enhanced security features and modern design.
Getting started with the modern Trezor Bridge implementation is straightforward through Trezor Suite.
Visit the official Trezor website at trezor.io and download Trezor Suite for your operating system. The Bridge functionality is included automatically.
Run the installer and follow the setup wizard. The installation process automatically configures all necessary components including Bridge.
Connect your Trezor hardware wallet via USB. Trezor Suite will automatically detect your device and establish a secure connection.
Confirm that your device is properly recognized and you can access all features through Trezor Suite's intuitive interface.
Always download Trezor Suite exclusively from the official Trezor website to avoid malicious software. Verify the authenticity of the application before installation.
If you encounter connectivity problems between your Trezor device and applications, these solutions may help resolve the issue.
Try different USB ports and cables, ensure Trezor Suite is running, and check if your device needs a firmware update.
Restart Trezor Suite, ensure no other cryptocurrency applications are running that might be interfering with the connection.
Ensure you're using a supported browser (Chrome, Firefox, Brave) and that no extensions are blocking Trezor connectivity.
On Windows, try reinstalling the drivers through Device Manager or use the Zadig tool to install the correct libusb drivers.
For persistent issues, visit the official Trezor Support page or community forums where you can find detailed guides and assistance from both the Trezor team and experienced users.
Trezor Bridge is designed with security as the fundamental principle, implementing multiple layers of protection for your cryptocurrency assets.
All Bridge communication occurs locally between applications on your computer and your Trezor device, with no external network exposure.
Every transaction must be physically verified on your Trezor device screen, preventing malicious software from altering transaction details.
The architecture prevents malware from intercepting or modifying communications, as private keys never leave the secure hardware environment.
Always verify transaction details on your Trezor device screen before confirming. This is your final protection against malicious software that might alter transaction information on your computer.
