Trezor Bridge — Browser to Device Connector

Securely connect your web browser to your Trezor hardware wallet for transactions, account management, and device operations.

Overview

Trezor Bridge serves as the essential communication layer between your browser and Trezor hardware wallet. It ensures encrypted and authenticated interactions for signing transactions, accessing accounts, and performing device management without exposing private keys.

1. Installation

Download Trezor Bridge from the official Trezor site. Install on Windows, macOS, or Linux following platform-specific instructions. Once installed, Trezor Bridge runs in the background and enables browsers to detect your Trezor device.

2. Connecting via Browser

  1. Ensure Trezor Bridge is running.
  2. Plug in your Trezor hardware wallet.
  3. Open a supported web wallet or Trezor web app.

3. Security Measures

  • Use only official downloads from the Trezor website.
