Trezor Bridge — Secure Connection for Your Trezor

What is Trezor Bridge?

Trezor Bridge is a lightweight background service that allows your Trezor hardware wallet to interact with supported web applications such as Trezor Suite Web and third-party integrations.

Without Trezor Bridge, your browser may be unable to detect or communicate securely with your Trezor device, especially on desktop operating systems.

Why Trezor Bridge is Important

Web browsers have strict security restrictions that prevent direct USB communication. Trezor Bridge solves this problem by acting as a secure intermediary between your hardware wallet and your browser.

✅ Enables communication via USB between your Trezor and browser
✅ Runs in the background securely and silently
✅ Automatically detects and connects your Trezor device
✅ Keeps your private keys safe by working only with authorized apps

Alternatives to Trezor Bridge

If you prefer not to install software on your machine, you can use the WebUSB connection method (available in some browsers like Chrome). However, WebUSB has limitations and may not support all features or platforms.

For the best experience, especially on desktop, Trezor Bridge is the recommended option.
