What is Trezor Bridge?
Trezor Bridge is the official SatoshiLabs application that creates a secure communication layer between your Trezor Hardware Wallet and desktop browsers. It enables Trezor Suite and supported web apps to detect your device, request signatures, and send transactions — while ensuring private keys never leave the hardware wallet.
The Bridge runs locally on your machine, handles permissions, and maintains a stable connection across Windows, macOS, and Linux. Because it’s lightweight and maintained by Trezor, it’s the recommended way to connect a Trezor device to browser-based wallet tools.
Step-by-Step: Install & Start with Trezor Bridge
Follow these steps carefully to install Trezor Bridge and ensure a safe, working setup.
- Verify your device — unbox your Trezor hardware wallet and confirm the tamper-evident seal is intact. Only proceed with an unopened device from an authorized seller.
- Download Bridge — open a browser and go to the official Trezor site. Choose “Trezor Bridge” and download the installer that matches your operating system (Windows/macOS/Linux). Avoid third-party sites to prevent fake installers.
- Run the installer — launch the downloaded package and follow the installer prompts. Administrative privileges may be required on some systems. Installation takes a minute and adds a background helper service.
- Connect your Trezor — plug the device into your computer with the supplied USB cable. The Bridge service should automatically detect the hardware and expose it to supported web apps and Trezor Suite.
- Open Trezor Suite or web app — visit the official Trezor Suite or compatible web application. The UI should prompt you to unlock or initialize the device. Complete any PIN or seed steps directly on the hardware device.
- Confirm transactions — when you send or sign a transaction, verify the details on the Trezor screen and confirm physically. This step guarantees your private keys never leave the device.
- Keep Bridge updated — allow automatic updates or periodically check the official site for new Bridge versions to stay protected against compatibility or security issues.
