Welcome to Trezor Bridge, the essential communication tool that connects your Trezor hardware wallet to your computer and web browser securely.
If you’ve just purchased a Trezor device or are setting it up for the first time, installing Trezor Bridge is one of the most important steps. It ensures your device communicates safely with Trezor Suite and other supported crypto applications — without exposing your sensitive information to the internet.
This guide will help you understand what Trezor Bridge is, why it’s required, how to install it correctly, and how to keep it updated for the best performance and security.
Trezor Bridge is a lightweight software application developed by SatoshiLabs, the creators of Trezor hardware wallets. It acts as a secure “bridge” between your Trezor device and your web browser or desktop app.
Without Trezor Bridge, your browser wouldn’t be able to detect or communicate with your Trezor hardware wallet properly.
Think of it as a private, encrypted tunnel that allows commands and confirmations to flow between your device and Trezor Suite — ensuring every transaction remains under your control.
Trezor Bridge provides security, compatibility, and performance advantages that make it an essential component of the Trezor ecosystem.
Here’s why it matters:
Trezor Bridge ensures that all data exchanged between your hardware wallet and Trezor Suite remains encrypted and protected. Your private keys never leave your device, and no sensitive data is stored online.
The Bridge enables your Trezor device to work flawlessly with browsers like Google Chrome, Mozilla Firefox, and Microsoft Edge, as well as Trezor Suite’s desktop and web versions.
Unlike outdated browser plugins, Trezor Bridge offers a stable, long-term solution that works consistently across operating systems.
Trezor Bridge is available for Windows, macOS, and Linux, ensuring every user can enjoy secure connectivity regardless of their system.
The software automatically checks for updates, helping you stay protected with the latest security enhancements.
Setting up Trezor Bridge takes just a few minutes. Follow the steps below to get started safely.
Always visit the official Trezor website to avoid phishing or fake software downloads:
👉 https://trezor.io/bridge
Never download Trezor Bridge from third-party websites, social media links, or ads.
On the Trezor Bridge page, select your operating system:
Windows (.exe)
macOS (.pkg)
Linux (.tar.gz)
Click “Download” to begin.
Once the file is downloaded:
Windows: Double-click the .exe file and follow the on-screen prompts.
macOS: Open the .pkg installer and follow the setup wizard.
Linux: Extract the archive and follow the included installation instructions.
You may be asked to enter your computer password or grant permission to install the software — this is normal for system-level apps like Trezor Bridge.
After installation, restart your browser or computer.
Then visit https://suite.trezor.io and connect your Trezor hardware wallet.
If Trezor Bridge is installed correctly, Trezor Suite will automatically recognize your device.
Once installed, Trezor Bridge runs silently in the background as a secure service.
When you connect your Trezor to your computer:
Your browser or Trezor Suite sends a connection request.
Trezor Bridge intercepts the request and creates a secure communication channel.
The hardware wallet confirms commands on-screen, ensuring you approve every transaction physically.
This process happens instantly — you won’t even notice it’s running. But behind the scenes, Trezor Bridge ensures every command remains encrypted, verified, and controlled locally.
If your Trezor device is not being recognized, follow these quick troubleshooting steps.
Quit and relaunch the Trezor Bridge process or restart your computer.
Unplug and reconnect your Trezor using the original USB cable.
Go to https://trezor.io/bridge and download the latest version. New releases fix compatibility issues and improve reliability.
Ensure your browser allows communication with local services (especially if using privacy extensions or firewalls).
If the issue persists, reinstall Trezor Suite to ensure full integration with the Bridge.
If the web version fails, try using the Trezor Suite desktop app, which includes the Bridge functionality internally.
If problems continue, visit the official Trezor Support Center for step-by-step help.
Trezor Bridge was designed with security as its top priority. However, good security practices are essential for maintaining your safety:
Always download Bridge updates directly from trezor.io.
Do not install third-party drivers claiming to “fix” connection issues.
Verify that your Trezor device shows the padlock icon and Trezor logo during setup.
Never enter your PIN or recovery seed on your computer — only on your Trezor device.
Trezor regularly releases updates to improve compatibility and patch vulnerabilities.
Disconnect your Trezor device.
Visit https://trezor.io/bridge.
Download and install the newest version for your OS.
The new version will automatically replace your old one. There’s no need to uninstall manually.
Supported operating systems:
Windows 10 and later
macOS 10.11 (El Capitan) and later
Linux (Ubuntu, Debian, Fedora, Arch, etc.)
Browser compatibility:
Google Chrome
Mozilla Firefox
Microsoft Edge
Trezor Suite versions supported:
Both desktop and web versions integrate seamlessly with Trezor Bridge.
You might wonder whether you need both Trezor Bridge and Trezor Suite.
Here’s the difference:
Trezor Bridge: Required for Trezor Suite Web (browser-based). It lets your device talk to your browser securely.
Trezor Suite Desktop: Includes Bridge functionality built-in, so no separate installation is needed.
If you prefer using Trezor Suite Desktop, you can skip installing Trezor Bridge. But if you’re accessing your wallet through your browser, Bridge is mandatory.
Trezor Bridge plays a vital role in the multi-layered security model of Trezor wallets.
Here’s what it protects you from:
🧠 Phishing attacks — Bridge ensures communication only with verified Trezor Suite instances.
🦠 Malware — Your private keys never touch the computer; only signed data passes through the Bridge.
🚫 Fake extensions — Bridge replaces outdated browser plugins that are vulnerable to attacks.
🔒 Unauthorized access — Each connection must be confirmed on your Trezor device.
By using Bridge, you maintain complete control over your digital assets.
Q: Do I need Trezor Bridge if I use Trezor Suite Desktop?
No. Trezor Suite Desktop already includes Bridge functionality.
Q: How do I know if Bridge is running?
It operates silently in the background. You can verify it’s active when Trezor Suite automatically detects your device.
Q: Is Trezor Bridge open-source?
Yes. Trezor Bridge is open-source, just like all Trezor software, allowing independent security verification.
Q: Will Trezor Bridge work on my company laptop?
Yes, but you may need admin rights to install software. Contact your IT administrator if needed.
Q: Is it safe to keep Bridge running?
Absolutely. It uses minimal resources and poses no security risk when installed from the official source.
Your Trezor hardware wallet is only as powerful as the connection that links it to your computer.
Installing Trezor Bridge ensures that connection remains private, verified, and secure — exactly as your crypto deserves.
