Secure communication software connecting your Trezor hardware wallet to web browsers

What is Trezor Bridge?

Trezor Bridge is a lightweight background service that enables secure communication between your Trezor hardware wallet and supported web browsers. It acts as a bridge between the Trezor Wallet interface and your physical device, allowing you to manage your cryptocurrencies safely.

Unlike browser extensions, Trezor Bridge runs as a standalone application in the background, providing a more stable and secure connection. It automatically detects when you connect your Trezor device and facilitates the communication needed for transaction signing and account management.

How It Works

Trezor Bridge operates through a straightforward process:

  1. Installation: The Bridge is installed on your computer as a background service.
  2. Connection: When you connect your Trezor device, the Bridge detects it automatically.
  3. Communication: As you interact with web wallets or services, the Bridge facilitates secure communication between the browser and your device.
  4. Transaction Signing: When a transaction needs approval, the request is securely passed to your Trezor device for verification.
  5. Confirmation: You physically confirm the transaction on your Trezor device, keeping your private keys secure.

This process ensures that your sensitive cryptographic operations always occur on the secure element of your Trezor device, never exposing your private keys to your computer or the internet.
