Trezor Bridge®

Discover how Trezor Bridge® enhances your Trezor Wallet experience by providing a secure connection between your hardware wallet and your computer.

Trezor Bridge is designed to work with a variety of web browsers, allowing you to interact with your Trezor Wallet securely across different platforms. Here's how it functions with different browsers and any compatibility requirements:

How Trezor Bridge Works with Web Browsers

1. Establishing Communication:

   • Background Service: Trezor Bridge operates as a background service on your computer. When you access a web-based application or Trezor Wallet through your browser, Trezor Bridge establishes a secure communication channel between your Trezor device and the browser.

   • API Integration: Trezor Bridge uses an internal API to facilitate the exchange of data and commands between your hardware wallet and the web application. This API is accessed by the Trezor Wallet web interface to perform operations securely.

2. Interfacing with Web Applications:

   • Detection: When you visit the Trezor Wallet website or other compatible web applications, the site detects the presence of Trezor Bridge running on your system. It then communicates with Trezor Bridge to access and manage your wallet.

   • Data Transmission: Trezor Bridge handles the secure transmission of data such as transaction requests and signing commands between the web application and your Trezor device.

3. Transaction Handling:

   • Transaction Requests: When you initiate a transaction or other operations through a web application, the request is sent to Trezor Bridge, which then forwards it to your Trezor device for confirmation.

   • Signing Operations: The actual signing of transactions is performed on the Trezor device itself, ensuring that your private keys remain secure and isolated from the browser environment.

Browser Compatibility Requirements

1. Supported Browsers:

   • Google Chrome: Trezor Bridge is fully compatible with Google Chrome and is often recommended for its reliable performance and broad support for web technologies.

   • Mozilla Firefox: Trezor Bridge also works well with Mozilla Firefox, providing a good user experience and integration.

   • Microsoft Edge: Modern versions of Microsoft Edge (based on Chromium) are compatible with Trezor Bridge, allowing seamless interaction with Trezor Wallet.

   • Safari: While Safari can work with Trezor Bridge, its compatibility may be less consistent compared to Chromium-based browsers like Chrome and Edge. Users may need to ensure they have the latest updates for optimal performance.

2. Compatibility Considerations:

   • Browser Extensions: Make sure to disable any browser extensions that could interfere with Trezor Bridge or compromise security. Some extensions might block or alter the communication between the browser and Trezor Bridge.

   • Browser Updates: Keep your browser up-to-date to ensure compatibility and security. Browser updates often include fixes and improvements that can enhance the performance of Trezor Bridge.

   • Operating System Support: Ensure that your operating system supports Trezor Bridge and the version of the browser you are using. Compatibility issues might arise on older operating systems or browsers.

Summary

Trezor Bridge works by acting as a secure intermediary between your Trezor device and various web browsers. It establishes a communication channel that allows web applications to interact with your Trezor Wallet while keeping sensitive data secure. For optimal performance, it is recommended to use up-to-date versions of Google Chrome, Mozilla Firefox, or Microsoft Edge. Safari is also supported but may have variable performance. Ensuring that your browser and Trezor Bridge are up-to-date and avoiding potentially disruptive extensions will help maintain a smooth and secure user experience.
