Trezor Bridge is a lightweight software component that enables secure communication between your Trezor hardware wallet and supported web browsers. It ensures that your device can interact safely with wallet interfaces while keeping private keys offline at all times.
Trezor Bridge acts as a background service that allows browsers to detect and communicate with a connected Trezor device. It replaces older browser plugins and provides a more stable, secure, and modern connection method.
Trezor Bridge is mainly required when using web-based wallet interfaces. For desktop applications like Trezor Suite Desktop, Trezor Bridge is usually not needed.
Trezor Bridge is available for the following platforms:
Once installed, Trezor Bridge runs automatically and does not require manual startup.
After installation, simply connect your Trezor device and open a supported web wallet interface. The browser will detect your device through Trezor Bridge and prompt you to confirm actions on the hardware wallet screen.
All sensitive operations, including login and transaction signing, must be approved directly on the Trezor device.
Trezor Bridge is designed for browser-based access, while Trezor Suite Desktop includes built-in communication features and does not rely on Trezor Bridge.
Trezor Bridge plays a crucial role in enabling secure browser-based access to Trezor hardware wallets. By acting as a trusted communication layer, it ensures seamless interaction between your device and web interfaces without compromising the safety of your private keys.
For the highest level of security, always use official Trezor software and verify connections directly on your hardware wallet.
