What is Trezor Bridge? 🧩

Trezor Bridge is a small background application that acts as a communication layer (a bridge) between a Trezor device connected to your computer via USB and the web-based Trezor Wallet interface. It handles low-level USB communications and provides a secure channel so that the browser can talk to the hardware device.

In short: it translates browser requests into USB instructions and relays responses back to the browser. Without Bridge (or another supported communication method), browsers can’t directly access USB-connected hardware securely in all environments.

Key responsibilities

  • Detect Trezor devices attached to the system.
  • Establish secure communication with the Trezor device.
  • Forward requests from the browser (like signing a transaction) to the device.
  • Manage updates and compatibility between device firmware and web wallet.

🛠️ Installation & Setup

Follow these high-level steps to install and set up Trezor Bridge. The specifics may vary by operating system (Windows, macOS, Linux).

Step 1 — Download

Obtain the Bridge installer from the official source. Always ensure you download from the official vendor site to avoid tampered installers. 🛡️

Step 2 — Install

Run the downloaded installer with administrative privileges if requested. On Windows, accept the UAC prompt; on macOS, allow the installer to run in System Preferences if macOS Gatekeeper blocks it.

Step 3 — Start & Verify

Once installed, Bridge usually runs in the background and may add an icon to the system tray or menu bar. Verify it’s running and open your web wallet in the browser to confirm it can detect your device.

Common CLI hints

If you prefer command-line interactions (Linux power users), you may check Bridge logs or run it from terminal to see verbose output. Example commands and paths depend on your distribution and installation method.

⚠️ Installing software that communicates with hardware wallets is sensitive—always verify signatures and download sources.
