What Is Trezor Bridge?

Trezor Bridge is a secure middleware component that enables your browser or Trezor UI (like Suite) to communicate with your Trezor hardware wallet over USB. Instead of using legacy browser plugins, Bridge runs locally and acts as a safe interface—so private keys stay on the device and can’t be accessed by malicious scripts.

Why Trezor Bridge Matters

Modern browsers and security models have deprecated old extension methods. Bridge ensures compatibility and strong security. It isolates the communication channel, shielding the device from direct browser access. Users of trezor.io or custom Trezor interfaces often need Bridge installed first to fully access wallet functions.

How Trezor Bridge Works

When a Trezor-compatible UI attempts to connect, it checks whether Bridge is installed. If not, the user is prompted to install it. Once running, Bridge listens on a local port. Commands from the UI—such as “connect device”, “get public key”, or “sign transaction”—are forwarded by the Bridge to the Trezor device over USB. Users then confirm actions on the device, ensuring the browser never directly touches private keys.

Download & Setup Trezor Bridge

Follow these steps to get started:

  1. Visit the official link or your interface page (Trezor.io).
  2. Select the Bridge installer for your OS: Windows, macOS, or Linux.
  3. Install Bridge and restart your browser if required.
  4. Reconnect your Trezor hardware wallet via USB.
  5. Authorize the connection via Bridge, then proceed to your UI (wallet, Suite, etc.).
