Trezor Bridge® | Securely Connect Your Hardware Wallet to the Web

Trezor Bridge is a communication tool that links your Trezor hardware wallet to your browser, enabling secure access to Trezor Suite. Learn how it works, how to install it, and how to troubleshoot common issues.

What is Trezor Bridge?

Trezor Bridge is a lightweight software that acts as a communication layer between your Trezor hardware wallet and your web browser. Developed by SatoshiLabs, the creators of the Trezor Model One and Trezor Model T, this bridge replaces older browser plugins and allows secure interactions with Trezor Suite, the official interface for managing crypto assets.

Whether you're checking balances, sending crypto, or interacting with decentralized apps (dApps), Trezor Bridge ensures your hardware wallet can communicate safely and seamlessly with your computer.

Why You Need Trezor Bridge

In modern browsers like Google Chrome, Mozilla Firefox, or Brave, traditional plugins and extensions face limitations due to heightened security protocols. Trezor Bridge bypasses these restrictions by enabling direct communication over a secure channel between the browser and the Trezor device.

Here’s why Trezor Bridge is essential:

• ✅ Secure Communication: Prevents man-in-the-middle (MITM) attacks or phishing attempts.
• ✅ No Browser Extension Required: You don’t need a browser plugin or WebUSB—Bridge handles everything.
• ✅ Compatible with Trezor Suite: Enables full functionality of your hardware wallet via the desktop application or web interface.
• ✅ Cross-Platform: Works on Windows, macOS, and Linux.

How to Install Trezor Bridge

Setting up Trezor Bridge is a simple process. Follow the steps below to get started:

Step 2: Download the Installer

Choose the correct installer for your operating system:

• Windows (.exe)
• macOS (.pkg)
• Linux (.deb or .tar.gz)

Step 3: Install and Restart

Step 4: Connect Your Trezor Device

Plug in your Trezor device and open Trezor Suite. You should now be able to interact securely with your wallet.

Troubleshooting Common Issues

If Trezor Bridge isn’t working, here are some tips:

1. "Trezor Not Found" Error

• Ensure your device is properly connected.
• Restart the browser or the Bridge process.
• Try a different USB port.

2. Bridge Not Recognized

3. Conflicts with Antivirus

Some antivirus or firewall tools may block the Bridge. Add it to the allowlist or temporarily disable your security software during use.

4. Browser Issues

Is Trezor Bridge Safe?

Yes, Trezor Bridge is completely safe—as long as you download it from the official Trezor website. It is an open-source utility, and its source code is publicly available for audit. Trezor never stores your private keys; everything is handled inside the device, and Bridge merely facilitates communication.

Advanced Usage for Developers

Trezor Bridge opens up APIs for developers interested in integrating Trezor into their own platforms or wallets. This allows dApps or custom scripts to communicate with Trezor devices via localhost ports, ensuring flexibility for advanced crypto users.
