This innovative approach maintains the highest security standards while providing users with a seamless experience when accessing their digital assets.
Trezor Bridge ensures your private keys never leave your hardware wallet, providing maximum protection against online threats.
Enjoy smooth, uninterrupted communication between your Trezor device and supported web applications.
Trezor Bridge automatically updates to ensure compatibility with the latest security protocols and features.
The Trezor Bridge application creates a secure communication layer that allows web browsers to interact with your Trezor hardware wallet without compromising security. When you connect your Trezor device to your computer, Trezor Bridge establishes a protected local connection that web applications can use to send signing requests and receive verified responses.
Trezor Suite or web wallet initiates communication
Processes and secures communication between components
Secure physical connection to Trezor device
Hardware wallet processes requests securely
When you interact with a Trezor-compatible web application, the following secure communication process occurs:
The web application (such as Trezor Suite) sends a request to Trezor Bridge through a secure local connection. This request could be for transaction signing, address generation, or any other operation that requires hardware wallet interaction.
Trezor Bridge receives the request, validates its format and origin, and prepares it for transmission to the connected Trezor device. The bridge acts as a security checkpoint, ensuring only legitimate requests reach your hardware wallet.
The processed request is sent to your Trezor device via USB connection. Your device receives the request and displays the relevant information on its screen for your verification and approval.
You physically verify the transaction details on your Trezor device's screen and confirm the operation by pressing the appropriate button. This step ensures that even if your computer is compromised, malicious transactions cannot be executed without your explicit approval.
After you confirm the operation on your device, the signed response is sent back through Trezor Bridge to the web application. The private keys never leave the secure environment of your hardware wallet during this entire process.
Trezor Bridge plays a critical role in maintaining the security integrity of the Trezor ecosystem while providing convenient access to your cryptocurrency assets.
Unlike browser extensions that operate within the browser environment and are susceptible to various attack vectors, Trezor Bridge runs as a separate system service with limited privileges. This isolation significantly reduces the attack surface and prevents browser-based malware from interfering with the communication between your Trezor device and web applications.
Trezor Bridge provides a standardized communication protocol that works consistently across different browsers and operating systems. This eliminates the need for browser-specific implementations and ensures that Trezor devices can interact securely with web applications regardless of the user's browser choice.
The standalone nature of Trezor Bridge allows for seamless automatic updates that don't depend on browser update cycles. This ensures that security enhancements and new features can be deployed quickly without requiring user intervention or browser extension updates.
Trezor Bridge eliminates the need for browser extensions that could potentially be compromised. By operating as a separate application, it creates an isolated environment that significantly reduces attack vectors while maintaining seamless functionality.
Trezor Bridge is designed to work seamlessly across various operating systems and with all current Trezor hardware wallet models.
Compatible with Windows 10 and later versions. Requires administrator privileges for installation but runs with standard user privileges.
