Trezor Bridge® | Secure Connection for Your Trezor® Wallet

Introduction to Trezor Bridge

Trezor Bridge is a crucial communication tool that allows your Trezor hardware wallet to interact securely with your computer’s web browser. Developed by SatoshiLabs, Trezor Bridge ensures a safe and seamless connection between your Trezor device (such as the Trezor Model T or Trezor One) and the Trezor Suite web interface.

Unlike browser extensions, Trezor Bridge operates as a background service, providing a more stable and secure connection without requiring additional plugins. It is compatible with major operating systems, including Windows, macOS, and Linux, making it an essential component for managing your cryptocurrencies securely.

Why Do You Need Trezor Bridge?

Trezor Bridge plays a vital role in maintaining the security and functionality of your Trezor wallet. Here’s why it’s necessary:

1. Secure Communication – Trezor Bridge establishes an encrypted connection between your Trezor device and the Trezor Suite, preventing man-in-the-middle attacks.
2. Browser Compatibility – It enables your Trezor wallet to work smoothly with Chrome, Firefox, Edge, and other major browsers without requiring additional extensions.
3. Firmware Updates – Trezor Bridge facilitates firmware updates, ensuring your device has the latest security patches and features.
4. Transaction Signing – It allows you to securely sign transactions directly from your Trezor hardware wallet.
5. No Third-Party Risks – Unlike some browser plugins, Trezor Bridge is an official tool developed by SatoshiLabs, minimizing security risks.

How Trezor Bridge Works

Trezor Bridge acts as a mediator between your Trezor hardware wallet and the Trezor web interface. Here’s a step-by-step breakdown of how it works:

1. Installation – You download and install Trezor Bridge on your computer.
2. Background Service – Once installed, it runs silently in the background, waiting for a connection request.
3. Device Detection – When you connect your Trezor wallet via USB, Trezor Bridge detects it.
4. Secure Handshake – The Bridge establishes a secure communication channel between your Trezor and the browser.
5. Transaction Verification – All transaction requests are sent to your Trezor device for physical confirmation (button press).
6. Data Encryption – All data transmitted is encrypted, ensuring no sensitive information is exposed.
