Trezor Bridge: What It Is & Why You Need It

Trezor Bridge is a lightweight communication tool that allows your computer to recognize and interact with your Trezor hardware wallet. If you plan to use your Trezor with a web browser, Trezor Bridge is often required to ensure smooth and secure communication between your device and wallet interface.

Security Tip: Only download Trezor Bridge from the official Trezor website to avoid fake or malicious software.

What Is Trezor Bridge?

Trezor Bridge is a background service that acts as a link between your Trezor hardware wallet and applications that need to communicate with it. Since browsers restrict direct access to USB devices for security reasons, Trezor Bridge provides a safe and reliable alternative connection method.

Why Do You Need Trezor Bridge?

Without Trezor Bridge, some browsers may not detect your Trezor device. This tool ensures smooth operation when:

Using Trezor Suite in browser mode
Connecting your Trezor Model One or Model T to web-based crypto apps
Interacting with third-party wallets that support Trezor

How Trezor Bridge Works

When installed, Trezor Bridge runs quietly in the background. It does not store any data and does not interfere with normal computer operations. Its primary job is simply to pass encrypted communication between your Trezor device and your browser or wallet interface.
