Trezor Bridge

A secure communication layer that connects your Trezor hardware wallet to web-based applications, enabling safe and seamless crypto management without exposing private keys.

What Is Trezor Bridge?

Trezor Bridge is an official background service developed by SatoshiLabs that allows web browsers to communicate securely with Trezor hardware wallets. It acts as a trusted link between your device and supported web applications.

Why Trezor Bridge Is Needed

Modern browsers limit direct access to USB devices for security reasons. Trezor Bridge solves this challenge by providing a stable and secure connection layer that ensures reliable device detection and interaction.

Stable Connectivity

Reduces connection errors and improves communication reliability between Trezor devices and supported browsers.

Background Operation

Runs quietly in the background, activating only when a Trezor device is connected and needed.

Browser Compatibility

Works with major browsers and web-based wallet interfaces that support Trezor hardware wallets.

How Trezor Bridge Works

  1. Install Trezor Bridge on your computer
  2. Connect your Trezor hardware wallet via USB
  3. Open a supported web application
  4. Trezor Bridge establishes a secure communication channel
  5. Confirm actions directly on your device
Security Note: Trezor Bridge never accesses or stores your private keys. All sensitive operations are handled exclusively on the hardware wallet.
