Trezor Bridge is an essential communication tool that allows your Trezor hardware wallet to connect securely with your web browser. It works behind the scenes to ensure smooth, encrypted communication between your Trezor device and supported applications like Trezor Suite and third-party wallet interfaces.

If you use your Trezor wallet on a desktop browser, Trezor Bridge helps your computer recognize and interact with the device safely — without exposing private keys or sensitive information.

What Is Trezor Bridge?

Trezor Bridge is a lightweight background service installed on your computer. It replaces older browser extensions that were previously required to connect hardware wallets. Instead of relying on browser plugins, Trezor Bridge creates a secure communication channel between:

• Your Trezor hardware wallet
• Your web browser
• Trezor Suite or compatible wallet apps

This makes device communication more stable, private, and secure.

Learn how it fits into the ecosystem in our Trezor Suite Guide.

Why Trezor Bridge Is Important

Without Trezor Bridge, many browsers cannot properly detect your Trezor device when using web-based wallet tools. Installing it ensures:

• Your Trezor wallet connects reliably
• Transactions are signed securely on-device
• No sensitive data is exposed to the browser
• Compatibility with modern browser security rules

It improves both performance and safety when interacting with crypto applications.

For setup guidance, see our Trezor Setup Tutorial.

How Trezor Bridge Works

When you plug in your Trezor device, Trezor Bridge acts as a translator between the wallet and your browser. Instead of sending private data, it only transmits necessary, encrypted information required for:

• Account access
• Address verification
• Transaction signing
• Device authentication

All private keys remain securely stored inside your Trezor hardware wallet.
