🔐 Official Site | Trezor Bridge | Getting Started

Welcome to the official guide for Trezor Bridge®. This powerful tool connects your Trezor hardware wallet to your web browser or desktop app securely and seamlessly. If you're setting up for the first time or troubleshooting connectivity, this guide is for you. 🚀

What Is Trezor Bridge?

Trezor Bridge is a background application that securely links your Trezor device to supported browsers and web apps. It functions as a middleware layer, managing encrypted communications between your computer and your hardware wallet. Think of it as the digital bridge between your crypto and your screen. 🌉

Why You Need It

🛡️ Secure Communication: Bridge encrypts and isolates communication between your browser and Trezor hardware.
⚙️ Cross-Platform Functionality: Compatible with Windows, macOS, and Linux.
🚀 Improved Stability: Reduces disconnects or unsupported browser issues.
🔄 Future-Proof: WebUSB and other tech updates don’t affect Bridge-based systems.

💡 Note: If you're using the Trezor Suite Desktop app, Bridge may not be necessary. However, it is essential when using web-based Suite or third-party applications.

📦 How to Install Trezor Bridge

Step 1: Download from the Official Source

Visit trezor.io/start and select the correct version for your operating system.

Step 2: Install the Software

Run the installer. Approve any security warnings (e.g., Gatekeeper on macOS or UAC on Windows).

Step 3: Launch and Verify

After installation, the Bridge service should run in the background. You can verify it's running by opening your browser and going to 127.0.0.1:21325. You should see a confirmation message.

Step 4: Connect Your Trezor

Plug in your Trezor device and open the Trezor Suite Web. Your device should now be detected instantly.

⚠️ Troubleshooting

“I installed Bridge, but my device still isn’t detected.”

Try restarting your computer.
Use a different USB cable (ensure it supports data).
Avoid USB hubs or docks — connect directly to the machine.
Temporarily disable antivirus or firewall blocking localhost (127.0.0.1).
Ensure no old Bridge versions or drivers conflict with the new one.

🔄 Keeping Bridge Up-to-Date

Bridge updates are critical for compatibility and security. Visit the official site regularly and reinstall if prompted in Suite.

🔐 Security Reminders

✅ Only use Bridge from trezor.io.
🚫 Never download from third-party sources.
🔑 Bridge does NOT store your seed or keys.
🧠 Always confirm all transactions on your Trezor screen.
