What is Trezor® Bridge?

Trezor Bridge is a dedicated communication tool developed by SatoshiLabs that enables web browsers to securely interact with Trezor® hardware wallets. It acts as a liaison between your browser and your Trezor® device, facilitating a secure connection without compromising the fundamental security principles of hardware wallets.

Unlike browser extensions that might have security vulnerabilities, Trezor Bridge operates as a standalone background application that creates a secure communication channel between web applications like Trezor Suite Web and your hardware wallet. This approach maintains the isolation of your private keys while allowing convenient browser-based access to your cryptocurrency assets.

How Trezor Bridge Works

Secure Communication Channel

Trezor Bridge establishes an encrypted local connection between your web browser and Trezor® device, ensuring that sensitive information never leaves your computer unprotected.

Background Operation

The application runs quietly in the background, automatically activating when you attempt to access your Trezor Wallet through a supported web browser.

Automatic Detection

Trezor Bridge automatically detects when your device is connected and ready for use, streamlining the Trezor Bridge login process.

Browser Compatibility

It supports all major browsers including Chrome, Firefox, Edge, and Brave, ensuring a consistent experience across different browsing environments.
