Welcome to the official guide on Trezor Bridge — the secure communication tool that connects your Trezor hardware wallet with your web browser and desktop applications.
If you use a Trezor Model One or Trezor Model T, Trezor Bridge is an essential piece of software that allows your computer to recognize and interact with your hardware wallet. It ensures a seamless, encrypted, and safe connection between your Trezor device and Trezor Suite — the official platform for managing your cryptocurrencies.
Let’s explore what Trezor Bridge is, why it’s important, and how to install and use it safely.
Trezor Bridge is a lightweight background application developed by SatoshiLabs, the creators of Trezor hardware wallets.
Its purpose is simple: it enables communication between your Trezor device and your browser or desktop software.
Without Trezor Bridge, your computer and web browser cannot detect or communicate with your Trezor hardware wallet properly.
Think of Trezor Bridge as a secure translator — it allows data to flow between your hardware wallet and your computer in a protected, encrypted manner, without ever exposing your private keys or recovery seed to the internet.
While hardware wallets are designed for offline security, they still need a way to interact with software — like Trezor Suite or third-party apps that support Trezor devices.
Trezor Bridge provides this secure channel. Here’s why it’s so critical:
Secure Device Communication
Trezor Bridge ensures your computer and wallet communicate safely without relying on browser extensions or plug-ins that could be insecure.
Cross-Browser Compatibility
It supports major browsers like Chrome, Firefox, Brave, and Edge, ensuring a smooth experience across platforms.
Local Connection (Not Cloud-Based)
Communication happens locally between your device and computer — not through online servers. Your private data never leaves your system.
Automatic Device Recognition
Once installed, Trezor Bridge automatically detects when your Trezor wallet is connected and communicates with the Trezor Suite app.
Improved Performance
Compared to older browser plug-ins like the deprecated “Trezor Chrome Extension,” Trezor Bridge provides faster, more reliable, and safer performance.
In short, Trezor Bridge is the foundation of your hardware wallet’s connection — without it, your browser or Trezor Suite won’t be able to interact with your device properly.
The official and only safe place to download Trezor Bridge is directly from Trezor’s website:
⚠️ Security Warning:
Never download Trezor Bridge or any Trezor-related software from unofficial or third-party websites. Fake download links are a common phishing tactic used by scammers to steal recovery seeds and private keys.
Always double-check the website address — it must start with https://trezor.io and include a secure padlock icon in your browser.
Follow these steps to safely install Trezor Bridge on your computer:
Visit https://trezor.io/bridge and select your operating system (Windows, macOS, or Linux).
Click “Download” to get the latest version of the Trezor Bridge installer.
On Windows, open the .exe file and follow the installation prompts.
On macOS, open the .dmg file and drag Trezor Bridge into your Applications folder.
On Linux, follow the command-line instructions provided on the Trezor website.
Your operating system may ask for permission to install or run the software — approve the request to continue.
Once installed, Trezor Bridge runs silently in the background. You can verify it’s working by opening Trezor Suite or going to suite.trezor.io — your device should now be detected automatically.
That’s it! No configuration or manual setup is required.
After installation, Trezor Bridge starts automatically every time you plug in your Trezor device.
Here’s how it works during a typical session:
Connect Your Trezor Wallet to your computer via USB.
Open Trezor Suite (desktop or web version).
Trezor Bridge establishes a local, encrypted communication channel between your device and the app.
You can now log in, manage your crypto, sign transactions, or update firmware securely.
Trezor Bridge doesn’t need to be opened manually or adjusted — it runs quietly in the background to maintain a safe, encrypted connection.
Trezor regularly releases updates to improve Bridge’s performance and security.
Visit https://trezor.io/bridge.
Download the latest version for your system.
Install it — it will replace the older version automatically.
Keeping Trezor Bridge updated ensures you always have the latest security patches and compatibility with new browser versions or firmware updates.
Occasionally, users may encounter connection issues. Here are common problems and solutions:
Ensure Trezor Bridge is installed and running.
Restart your browser and computer.
Reconnect your Trezor device.
Try a different USB port or cable.
If your browser still asks you to install Trezor Bridge even though it’s already installed:
Refresh the page in suite.trezor.io.
Clear your browser cache.
Ensure you’re not using privacy extensions that block local connections.
If the issue persists, uninstall Trezor Bridge completely and reinstall the latest version from trezor.io/bridge.
Sometimes, security software can block local communication. Add Trezor Bridge to your antivirus or firewall exceptions list.
Make sure you’ve configured udev rules properly as outlined in Trezor’s Linux installation guide.
If you still face issues, visit the Trezor Support Center at trezor.io/support for detailed troubleshooting steps.
Trezor Bridge is built with security and privacy as top priorities.
Here’s how your data stays protected:
End-to-End Encryption: Communication between your device and browser is encrypted and authenticated.
Local Processing: All interactions happen on your computer — no cloud or remote data transmission.
No Data Collection: Trezor Bridge doesn’t store or send personal data, recovery seeds, or wallet information.
Open-Source Code: Its source code is fully transparent and publicly available for independent security audits.
With these protections, you can use your Trezor wallet knowing that no one — not even Trezor — can access your private information or crypto assets.
