Trezor Bridge is the essential communication tool that facilitates a secure connection between your Trezor device and your internet browser. Ensure your assets remain safe with the official bridge software.
Bridge is running securely
Understanding the critical layer between your cold storage and the digital world.
Trezor Bridge is a lightweight application designed to run in the background of your computer. Its primary function is to facilitate communication between your Trezor hardware wallet and web browsers. Before the introduction of Trezor Bridge, users relied on browser plugins, which have since become obsolete due to security updates in modern browsers like Chrome and Firefox.
By installing Trezor Bridge, you create a local server that listens for signals from your Trezor device via USB. When you access Trezor Suite for Web or other compatible third-party wallets (like MyEtherWallet or MetaMask), the website sends requests to this local bridge rather than trying to access the USB hardware directly—something modern browsers restrict for security reasons.
This architecture ensures that your private keys never leave the physical device. The Bridge only transmits public data (like addresses) and signed transaction data, maintaining the core security promise of hardware wallets: complete isolation of sensitive cryptographic material from potentially compromised online environments.
Establishes an encrypted communication channel that prevents man-in-the-middle attacks.
Works seamlessly across Chrome, Firefox, Brave, and other major web browsers.
Faster data transmission rates compared to the older WebUSB standard.
Runs entirely on localhost (127.0.0.1), ensuring no external server dependency.
Why millions of users trust Trezor Bridge for their crypto operations.
The bridge minimizes the attack surface by handling USB communication outside the browser environment, protecting against malicious extensions.
Once installed, the Trezor Bridge runs silently in the background. It doesn't require manual launching every time you want to use your wallet.
Engineered to be extremely lightweight, consuming negligible system resources (RAM and CPU) while waiting for device connection.
Acts as a universal driver for all Trezor models (Model One, Model T, Safe 3), eliminating the need for model-specific drivers.

Common queries about Trezor Bridge installation and usage.
This software is provided "as is", without warranty of any kind. Always verify that you are downloading Trezor software from the official domain. Phishing attacks often mimic download pages. Check the URL bar for the correct domain certificate. Never enter your recovery seed phrase on your computer keyboard; it should only ever be entered on the Trezor device itself.
