Trezor Bridge is a background communication tool developed by Trezor that allows your web browser to securely interact with a Trezor hardware wallet. It acts as a bridge between your device and supported web applications, enabling smooth and secure cryptocurrency operations.
Trezor Bridge is especially useful for users who access their wallet through browser-based interfaces.
Trezor Bridge is a small application installed on your computer that enables communication between:
Your Trezor hardware wallet
Web browsers (Chrome, Firefox, etc.)
Supported crypto applications
It ensures that your browser can safely detect and communicate with your Trezor device.
Modern browsers often block direct hardware communication for security reasons. Trezor Bridge solves this by:
Enabling secure USB communication
Allowing web apps to detect Trezor devices
Ensuring stable wallet connectivity
Improving compatibility with Trezor services
All communication between browser and device is encrypted and secure.
Once installed, it automatically detects connected Trezor wallets.
