Trezõr® Brïdge® | Secure Crypto Management®

Welcome to the official guide for Trezõr® Brïdge®, the essential connectivity layer between your Trezor hardware wallet and your web browser. Whether you're managing Bitcoin, Ethereum, or any supported cryptocurrency, Trezor Bridge ensures a 🔐 secure and seamless experience.

“Your crypto assets are only as secure as your connection — that’s where Trezõr® Brïdge® comes in.”

What is Trezõr® Brïdge®?

Trezor Bridge is a lightweight background application that facilitates communication between your Trezor hardware wallet and supported browsers like Chrome, Firefox, Brave, and Edge. When you plug in your Trezor device, the Bridge ensures that all requests and transactions made from your browser are securely handled via your device.

Without the Bridge, your browser can’t interact directly with the Trezor device, which is why installing it is a crucial step in secure crypto management. 🛠️

Why is the Bridge Necessary?

Browser environments are sandboxed for security, which means hardware wallets cannot directly communicate with browser tabs. Trezor Bridge serves as a secure and trusted mediator, enabling:

Device Detection: Recognize when your Trezor device is plugged in
Secure Operations: Allow transactions, address verification, and seed handling to pass securely via the hardware device
Universal Compatibility: Bridge works with most modern browsers

Important: Trezor Bridge is required for users who do not use the standalone Trezor Suite desktop application but prefer browser-based wallet management.

Installing Trezõr® Brïdge®

Step 1: Download from the Official Website

To install Trezor Bridge, visit the official download page:

https://trezor.io/bridge/

Select your operating system (Windows, macOS, or Linux) and download the appropriate installer.

Step 2: Run the Installer

Windows: Double-click the `.exe` file and follow the setup instructions.
macOS: Open the `.dmg` file and drag the Bridge app into your Applications folder.
Linux: Follow the terminal instructions provided on the website.

🚫 Never download the Bridge from unofficial websites. This can compromise your device and funds.

Step 3: Reboot Your Browser

Once installed, restart your browser to complete the setup. The Bridge will run in the background automatically whenever your system starts.

Using Trezor Bridge with Web Wallets

Trezor Bridge is primarily used with web-based wallet interfaces such as:

Trezor Suite Web
Third-party integrations like MyEtherWallet (MEW), MetaMask (via Trezor), Electrum, and others

Once connected, your device will display prompts on-screen to confirm sensitive actions like signing, sending, or verifying addresses.

Security Tip 🛡️

Always verify recipient addresses and transaction amounts on the Trezor device screen before confirming. If what’s on the device doesn’t match your computer screen, cancel immediately.

Updating Trezor Bridge

The Trezor Bridge software is regularly updated to patch vulnerabilities, improve compatibility, and enhance performance.

How to Update:

Visit https://trezor.io/bridge/ regularly to check for new versions
Uninstall the old version if prompted and install the new package
Restart your browser after updating

Tip: Enable auto-updates or check monthly to ensure you're protected with the latest version.

Common Troubleshooting

If you run into problems with Trezor Bridge, try the following solutions:

Browser Doesn’t Detect Device: Restart the browser and ensure the Bridge is running in the background.
Device Not Recognized: Try a different USB cable or port. Some USB hubs are incompatible.
Conflicting Software: Close other apps that may interfere (e.g., antivirus, USB managers).
Permissions Issue: Ensure your browser has permissions to access USB devices (in Settings).

Security Considerations

Trezor Bridge is developed by SatoshiLabs® and is 100% open-source. You can view the source code and verify its integrity on GitHub:

What It Doesn’t Do:

Does not store or access your private keys
Does not have access to your funds or seed phrases
Acts only as a communication interface between device and browser

This ensures that you stay in full control of your crypto — always. 🔐
