Trezor Bridge | Secure Connection for Your Hardware Wallet

What Is Trezor Bridge?

Trezor Bridge is the essential communication service that connects your Trezor hardware wallet with supported desktop applications and browsers. Without it, your wallet cannot securely interact with the software interface that manages your crypto assets. It ensures encrypted data transfer between your device and your computer, making sure your private keys never leave your Trezor wallet.

How to Set Up Trezor Bridge

1. Download and install Trezor Bridge from the official Trezor source appropriate for your operating system (Windows, macOS, or Linux).

2. After installation, connect your Trezor device to your computer using the original USB cable.

3. Open your crypto management app or Trezor Suite. The software will automatically detect your hardware wallet through Trezor Bridge.

Why Trezor Bridge Matters

Trezor Bridge is more than just a background service — it’s a trust layer that ensures hardware-level security for every transaction.
