Trezor Bridge enables seamless, secure communication between your Trezor hardware wallet and web browser, allowing you to safely manage your cryptocurrencies through Trezor Suite.
Trezor Bridge acts as a secure communication layer that connects your Trezor hardware wallet to web-based applications like Trezor Suite, ensuring your private keys never leave your device.
By handling all communication between your browser and Trezor device, Bridge prevents potential browser-based attacks and ensures that sensitive operations remain isolated within your hardware wallet.
Once installed, Trezor Bridge works silently in the background, automatically detecting when your Trezor device is connected and establishing a secure channel for communication.
Trezor Bridge is a lightweight background service that facilitates secure communication between your Trezor hardware wallet and web applications like Trezor Suite. It acts as a critical security component in the Trezor ecosystem, ensuring that your private keys remain protected within your hardware wallet while still allowing you to interact with web-based interfaces.
Unlike browser extensions that can be vulnerable to various attacks, Trezor Bridge runs as a separate application on your computer, creating a more secure communication channel. This architecture prevents malicious websites from directly interacting with your Trezor device, significantly reducing the attack surface.
The Bridge application automatically starts when your computer boots up and runs in the background, waiting for connection requests from supported web applications. When you connect your Trezor device and visit Trezor Suite, the Bridge service establishes a secure USB connection that allows the web interface to communicate with your hardware wallet without ever having direct access to your private keys.
This approach combines the convenience of web applications with the security of hardware wallets, creating an optimal user experience without compromising on safety. Trezor Bridge is compatible with all Trezor hardware wallet models and supports all major operating systems including Windows, macOS, and Linux.
Trezor Bridge incorporates several important features that enhance both security and user experience when managing cryptocurrencies with your Trezor hardware wallet.
Trezor Bridge automatically detects when your device is connected and prepares it for secure communication with web applications.
Available for Windows, macOS, and Linux, ensuring consistent security across all major operating systems.
Runs silently in the background without requiring user interaction once installed and configured.
Establishes encrypted communication channels between your browser and Trezor device using advanced cryptographic protocols.
One of the most significant benefits of Trezor Bridge is its ability to work with multiple browsers simultaneously. Once installed, you can use Trezor Suite through Chrome, Firefox, Edge, or other supported browsers without needing to install separate extensions for each one.
The Bridge also handles firmware updates for your Trezor device, ensuring that you always have the latest security enhancements and features. When an update is available, Trezor Suite will notify you and guide you through the secure update process using the Bridge connection.
Trezor Bridge operates on a client-server architecture where the Bridge acts as a local server that mediates communication between web applications and your Trezor device. This creates a secure separation between potentially vulnerable browser environments and your hardware wallet.

All sensitive operations, such as signing transactions or revealing private keys, require physical confirmation on your Trezor device. The Bridge merely facilitates the communication - it never has access to your private keys or recovery seed, which always remain securely stored within your hardware wallet's protected memory.
This architecture ensures that even if your computer is compromised by malware, an attacker cannot access your cryptocurrencies without physical access to your Trezor device and knowledge of your PIN. The Bridge adds an additional layer of protection by preventing browser-based attacks from directly interacting with your hardware wallet.
Setting up Trezor Bridge is a straightforward process designed to get your Trezor device working with web applications quickly and securely. The installation process varies slightly depending on your operating system but follows the same general principles.
For most users, the simplest way to install Trezor Bridge is through the automatic prompt when first connecting your Trezor device. When you connect your Trezor to your computer and visit Trezor Suite for the first time, the application will detect that Bridge is not installed and provide instructions for downloading and installing it.
Alternatively, you can manually download Trezor Bridge from the official Trezor website. It's important to always download software from official sources to avoid malicious versions that could compromise your security. The website will automatically detect your operating system and provide the appropriate installer.
After installation, Trezor Bridge runs as a background service that automatically starts when your computer boots up. You typically won't need to interact with it directly - it works silently to facilitate secure communication between your Trezor device and supported web applications.
If you encounter connection issues, the Trezor Bridge interface (accessible through your system tray or applications folder) provides troubleshooting options and connection status information. Regular updates ensure compatibility with new Trezor device features and security enhancements.
Trezor Bridge is designed to enhance the security of your Trezor hardware wallet when interacting with web applications. However, users must follow security best practices to maintain protection. Always download Trezor Bridge and related software directly from the official Trezor website to avoid malicious versions. Keep your operating system, browsers, and Trezor Bridge updated to the latest versions. Never share your recovery seed with anyone, and store it securely offline. Be cautious of phishing attempts and only use official Trezor websites and applications. Remember that cryptocurrency transactions are irreversible - always verify transaction details on your Trezor device screen before confirming.
