Background communication service connecting Trezor hardware wallets with supported browsers
Trezor Bridge is a lightweight software component that enables communication between Trezor hardware wallets and web browsers. Modern browsers restrict direct USB communication for security reasons, and Trezor Bridge acts as a secure intermediary, allowing web applications like Trezor Suite Web to interact with a connected device safely. It runs silently in the background once installed and ensures seamless device recognition.
The primary role of Trezor Bridge is to replace older browser plugins and provide a stable communication channel. Without it, browsers cannot detect or communicate with the hardware wallet during web-based interactions.
When a Trezor device is connected via USB, Trezor Bridge creates a secure local connection between the device and supported web interfaces. It translates browser requests into device-readable commands while ensuring that sensitive operations, such as private key handling, remain on the hardware wallet.
The service runs in the background using minimal system resources.
Ensures compatibility with new firmware and browser versions.
All communication occurs locally, minimizing exposure to external threats.
Works on major operating systems, providing consistent performance.
Trezor Bridge does not access cryptocurrency funds. Transactions must still be confirmed on the hardware device screen. This design ensures that even if the host computer is compromised, private keys remain protected.
If the device is not detected, restarting the service or reconnecting the device usually resolves the issue.
Trezor Bridge is an essential communication layer for users who access their Trezor hardware wallet through web applications. By maintaining a secure local connection, it ensures safe and reliable device interaction without compromising private key security.
