What is Trezor Bridge?
Trezor Bridge is a small communication software that acts as a secure link between your Trezor hardware wallet and your web browser. It allows web-based applications like Trezor Suite Web or third-party dApps to communicate with your Trezor device through USB — safely and efficiently.
Without Trezor Bridge, your browser cannot detect or interact with the Trezor device, which is essential for signing transactions, viewing wallet data, and performing crypto operations.

Why Do You Need Trezor Bridge?
- Enables USB communication between Trezor and browser apps
- Allows Trezor Suite Web to detect your device
- Works across all major browsers: Chrome, Firefox, Brave, and Edge
- Essential for using Trezor with third-party wallets and Web3 apps
Important: Trezor Bridge is only required for the **web version** of Trezor Suite. If you're using the **desktop app**, Trezor Bridge is not needed.
How Does Trezor Bridge Work?
Trezor Bridge runs as a background service on your computer. When you visit a Trezor-compatible web application, the site requests permission to access your Trezor device via the Bridge. After you authorize the action on your Trezor hardware, the app can perform tasks like sending crypto or verifying account balances — all without exposing private keys.
