Trezor Bridge

A secure communication layer that connects your Trezor hardware wallet with browsers and web applications—without ever exposing your private keys.

What Is Trezor Bridge?

Trezor Bridge is official software developed by Trezor to enable secure communication between a Trezor hardware wallet and web-based applications. It acts as a background service that allows browsers to detect and interact with the connected Trezor device.

Instead of relying solely on browser extensions or outdated plugins, Trezor Bridge provides a stable and efficient connection channel that maintains the high security standards expected from Trezor products.

Why Trezor Bridge Is Important

Modern web browsers restrict direct access to USB devices for security reasons. Trezor Bridge solves this challenge by safely mediating communication between the browser and your hardware wallet.

Reliable Device Detection

Ensures your Trezor is consistently recognized by supported browsers and web interfaces.

Secure Data Transfer

All communication is encrypted, and private keys never leave the hardware wallet.

Seamless User Experience

Runs silently in the background, eliminating repeated setup and connection errors.

How Trezor Bridge Works

Trezor Bridge operates as a lightweight service installed on your computer. When a supported website or application requests access to the hardware wallet, Bridge securely forwards the request to the Trezor device.

  1. User connects the Trezor device via USB
  2. Browser sends a request through Trezor Bridge
  3. Trezor device displays the request for confirmation
  4. User approves the action on the device screen
Security Note: Trezor Bridge cannot access or store private keys. It only transmits encrypted commands.

Trezor Bridge and Trezor Suite

Trezor Bridge works alongside Trezor Suite to ensure smooth communication across different platforms. While Trezor Suite provides the user interface, Bridge ensures the device connection remains stable and secure.

In many cases, Trezor Suite includes Bridge functionality automatically, reducing the need for separate configuration.

Supported Platforms and Browsers

Keeping your operating system and browser updated ensures the best experience with Trezor Bridge.
