Trezor Bridge — Secure Connection for Your Trezor

What is Trezor Bridge?

Trezor Bridge is a background service that securely links your Trezor hardware wallet to supported web browsers and apps. It ensures every crypto transaction is processed with the highest security: your private keys never leave your device, and all communications are encrypted.

Encrypted Communications

All data between wallet and browser is encrypted—keys never leave your device, only signed data is sent.

Automatic Recognition

Bridge detects your connected Trezor instantly for seamless browser wallet management.

Cross-Platform

Works on Windows, Mac, Linux, Chrome, Edge, and Firefox browsers.

Third-Party Integration

Enables Trezor to connect with apps like MetaMask, Exodus, MyEtherWallet, and dApps.

How Does it Work?

Bridge listens for requests from your web app or wallet in the browser.
When an operation (sign/send) is requested, Bridge passes it to Trezor for secure physical confirmation.
Trezor signs or approves, then Bridge safely relays the result back to your browser, never exposing your private keys.

Why is Trezor Bridge Secure?

Encryption: No unprotected messages travel between device and browser.
No Exposed Keys: Critical keys stay inside Trezor—never on your computer or online.
Local Service: Reduces vulnerabilities compared to browser extensions.
Regular Updates: Latest security features and compatibility fixes.

When Should You Use Bridge?

Connecting Trezor to web wallet apps that lack native USB/WebUSB support.
Using browsers like Firefox, or legacy setups where WebUSB is not available.
Interacting with platforms that support Trezor through Bridge (MetaMask, Exodus, dApps).
