Trezor Bridge is a small native app that enables communication between your Trezor hardware wallet and web applications or the Trezor Suite. It’s required in some environments to securely forward messages between your browser and the connected device.
Trezor Bridge is an official, lightweight background service that facilitates secure USB/WebUSB/HTTP communication with your Trezor device. It avoids exposing low-level device interfaces to web pages and provides a controlled handshake that requires user confirmation on the hardware device for sensitive actions.
Provides a secure channel between your Trezor and browser or desktop app without exposing low-level ports.
Minimal footprint and auto-start options for convenience.
Available for Windows, macOS, and major Linux distributions.
Keeps the connector up to date to maintain compatibility and security.
Handshakes require device confirmation to prevent unauthorized access from web pages.
Provides stable APIs for integrations and third-party wallets while preserving security boundaries.
Trezor Bridge is developed by the same team behind Trezor hardware wallets and follows the same security-first approach. It is audited, regularly updated, and designed to minimize attack surface by separating web interfaces from device-level communication. Official distribution and signature verification further reduce the risk of tampered installers.
Not always. Some platforms support direct WebUSB communication without Bridge, but Bridge improves compatibility and offers a stable, secure connector for many browsers and environments.
Bridge typically updates automatically or prompts when a new version is available. You can also reinstall the latest installer from the official site.
Check your USB cable, allow permissions in your OS, restart the Bridge service, or reinstall the app. Also ensure the device is unlocked and on the home screen.
Yes. Bridge is a trusted utility that runs locally and only facilitates secure communication between your device and approved applications.
Yes — if you prefer direct WebUSB connections and your environment supports it, you can uninstall Bridge, though some apps may require it.
