Trezor Bridge is a communication tool developed by SatoshiLabs that enables supported web applications to communicate securely with your Trezor hardware wallet. It acts as a bridge between your web browser and your Trezor device, allowing compatible websites and wallet interfaces to detect and interact with your hardware wallet.
Although many users primarily manage their wallets through Trezor Suite, Trezor Bridge remains important for certain browser-based applications and services that require direct communication with a Trezor device.
Trezor Bridge is lightweight software installed on your computer that allows supported web browsers to communicate with your connected Trezor hardware wallet. It replaces older browser plugin methods and provides a more secure and reliable connection.
The software runs in the background and enables compatible web applications to recognize your Trezor device without exposing your private keys.
Trezor Bridge helps ensure smooth communication between your hardware wallet and supported browser-based services.
Its main purposes include:
Detecting your connected Trezor device
Enabling secure browser communication
Supporting browser-based wallet access
Improving compatibility with supported web applications
Providing reliable device connectivity
Your private keys remain stored securely on the Trezor hardware wallet throughout the process.
Trezor Bridge creates a secure connection between your browser and hardware wallet while ensuring sensitive information never leaves the device.
Once installed, compatible websites can automatically detect your connected Trezor device.
The software runs quietly in the background without requiring constant user interaction.
Trezor Bridge is available for major desktop operating systems, including:
Windows
macOS
Linux
