Trezor Bridge Guide — Secure. Simple. Transparent.

Trezor Bridge is the invisible layer that connects your Trezor hardware wallet with your browser or desktop app. Learn how it works, why it matters, and how to keep your crypto setup secure and smooth.

What Is Trezor Bridge?

Trezor Bridge is a lightweight application built by SatoshiLabs to enable secure communication between your computer and the Trezor hardware wallet. It acts as a translator between your web browser and your physical device — ensuring smooth data exchange without exposing sensitive keys.

Why It Matters

Modern browsers restrict direct USB access for safety reasons. Without Bridge, your Trezor wallet might not connect properly. Bridge ensures a stable and private communication layer that works across operating systems and browsers — handling data transfers while keeping your private keys inside your Trezor device.

How to Install Trezor Bridge

  1. Visit the official Trezor website.
  2. Download Bridge for your OS (Windows, macOS, or Linux).
  3. Run the installer and follow on-screen steps.
  4. Once installed, reconnect your Trezor and refresh the wallet page.

Security & Best Practices

Always verify prompts Double-check all transaction details on your Trezor screen before confirming.
Download only from Trezor.io Avoid fake download links — only use official Trezor sources.
Keep software updated Regularly update Bridge, firmware, and your OS for the best security.
Stay malware-free Use antivirus tools and avoid installing untrusted applications.

Troubleshooting Tips

Device not detected? Check the USB cable (make sure it’s data-capable), try a new port, or restart Bridge.

Browser can’t connect? Disable blocking extensions and ensure localhost connections are allowed.

Still stuck? Reinstall Bridge or contact official Trezor support — never share your recovery seed.
