Trezor Bridge is a lightweight background service that enables secure communication between your Trezor hardware wallet and web browsers. It acts as a crucial security layer that facilitates the interaction between the Trezor Suite web application and your physical device.
Unlike traditional browser extensions, Trezor Bridge operates as a standalone application that runs in the background. This approach provides enhanced security by isolating the communication channel from potential browser-based threats and vulnerabilities.
The bridge handles all USB communication with your Trezor device, processes security protocols, and ensures that sensitive operations like transaction signing occur securely within the hardware wallet environment. Your private keys never leave the Trezor device, maintaining the highest level of security.

Common questions about Trezor Bridge installation and usage
No, the desktop version of Trezor Suite includes built-in communication capabilities and doesn't require Trezor Bridge. Bridge is specifically designed for the web version of Trezor Suite to facilitate secure communication between your browser and Trezor device. The desktop application handles device communication natively without needing an additional bridge service.
Yes, Trezor Bridge is developed and maintained by SatoshiLabs, the company behind Trezor hardware wallets. It's open-source software that undergoes regular security audits. The bridge doesn't handle private keys or sensitive data - it only facilitates communication between your browser and hardware wallet. All cryptographic operations occur securely within your Trezor device, ensuring your keys never leave the hardware wallet.
Web browsers have security restrictions that prevent direct communication with USB devices for security reasons. Trezor Bridge acts as a secure intermediary that bypasses these restrictions while maintaining security. It creates a standardized communication protocol that works across different browsers and operating systems, ensuring consistent and secure access to your Trezor device without compromising browser security models.
Trezor Bridge can be updated in several ways. The application checks for updates automatically and may prompt you when a new version is available. You can also manually download the latest version from this page and install it over the existing version. On some systems, Bridge updates through the standard system update mechanisms. It's recommended to keep Bridge updated to ensure compatibility with the latest Trezor firmware and security improvements.
Trezor Bridge is specifically designed for use with Trezor Suite and the official Trezor web interface. However, some third-party applications and wallets that support Trezor devices may also utilize Bridge for communication. The compatibility depends on whether the third-party application is designed to work with Trezor Bridge. For the best experience and security, we recommend using the official Trezor Suite application with your Trezor device.
