What is Trezor Bridge?
Trezor Bridge is a background service that enables secure communication between your Trezor hardware wallet and supported web browsers. It acts as a facilitator, allowing your browser to interact with your Trezor device without compromising security.
Trezor Bridge runs locally on your computer and establishes a secure connection between the Trezor Wallet interface in your browser and your physical Trezor device. This ensures that your private keys never leave your hardware wallet, maintaining the highest level of security for your cryptocurrencies.
Unlike browser extensions that might have security vulnerabilities, Trezor Bridge operates as a separate application, providing an additional layer of protection against potential browser-based threats.
How Trezor Bridge Works
Trezor Bridge creates a secure communication channel using the following process:
- Installation: Trezor Bridge is installed on your computer as a background service that starts automatically when your system boots.
- Connection: When you connect your Trezor device to your computer, Trezor Bridge detects it and prepares for communication.
- Browser Interaction: When you visit the Trezor Wallet web interface, it communicates with the locally running Trezor Bridge service.
- Secure Data Transfer: Trezor Bridge facilitates the exchange of information between the browser and your Trezor device, ensuring sensitive operations like transaction signing happen securely on the device itself.
- Verification: All actions requiring private key access must be physically confirmed on your Trezor device, providing an additional layer of security.

Trezor Bridge is compatible with major operating systems including Windows, macOS, and Linux. It works with popular browsers like Chrome, Firefox, and Brave that support the necessary communication protocols.

Security Considerations

- No Private Key Exposure: Your private keys remain securely stored in your Trezor hardware wallet at all times.
- Verified Communication: All communication between the browser and Trezor Bridge is cryptographically verified.
- Minimal Attack Surface: By operating as a separate service rather than a browser extension, Trezor Bridge reduces potential attack vectors.
- Physical Confirmation: Every transaction requires physical confirmation on your Trezor device, preventing unauthorized operations.

- Always download Trezor Bridge from the official Trezor website
- Keep your operating system and Trezor Bridge updated
- Verify the URL of the Trezor Wallet interface before use
