If you're using a Trezor hardware wallet, one tool is absolutely essential for a smooth, secure experience on your computer: Trezor Bridge. Acting as a trusted communication layer between your browser and your Trezor device, this lightweight utility ensures you can manage your cryptocurrency with ease—without ever compromising your private keys.
Whether you're setting up a new device through Trezor.io/Start®, interacting with dApps, or accessing your wallet via Trezor Suite Web, Trezor Bridge keeps everything running safely behind the scenes.
Trezor Bridge is a background application developed by SatoshiLabs, the creators of the Trezor hardware wallet. It enables your web browser to recognize and securely communicate with your Trezor Model T or Trezor Model One via USB.
Before Trezor Bridge existed, users relied on browser extensions like the Chrome Trezor plugin. But those are now outdated. Trezor Bridge is the modern, more secure alternative that’s fully compatible with all major browsers and operating systems.
Without Trezor Bridge, your browser won’t detect your wallet, and many features in Trezor Suite Web, Trezor.io/Start®, and third-party tools like MetaMask won’t work. Here’s why installing Trezor Bridge is non-negotiable:
Your private keys never leave your device. Trezor Bridge ensures that your device communicates only with trusted software, enabling offline transaction signing from the browser.
Trezor Bridge is available for Windows, macOS, and Linux, and works across all major browsers including Chrome, Firefox, Edge, and Brave.
Using MetaMask with Trezor? Signing Ethereum smart contracts or accessing DeFi platforms? Trezor Bridge makes it possible—safely and reliably.
Once installed, Trezor Bridge runs silently in the background. You don’t need to launch it manually—it auto-activates when a Trezor-supported site or app is in use.
Installing Trezor Bridge is easy and takes less than 2 minutes:
⚠️ Important: Only download Trezor Bridge from the official Trezor website to avoid phishing attacks or malware.
Trezor Bridge acts as a secure relay between your connected hardware wallet and your browser-based interfaces. When you use a web tool like Trezor Suite Web or MetaMask, your browser sends a signal to Trezor Bridge. The bridge then facilitates that communication, ensuring that:
In essence, Trezor Bridge is the invisible protector ensuring safe operation of your wallet over USB and browser.
