Trezor Bridge — Secure Connection Between Your Trezor Wallet and Browser
When using a hardware wallet, the connection between your device and computer must be both reliable and secure. Trezor Bridge is the communication software that allows your Trezor hardware wallet to interact smoothly with web browsers and supported applications. It acts as a secure background service, enabling safe data exchange without exposing your private keys.
If you use Trezor Suite in a browser or access third-party crypto services, Trezor Bridge plays a key role in maintaining a seamless and protected connection.
What Is Trezor Bridge?
Trezor Bridge is a lightweight software component installed on your computer that allows web-based applications to communicate with your Trezor hardware wallet. Modern browsers limit direct USB device communication for security reasons, and Trezor Bridge solves this by acting as a trusted intermediary.
Instead of your browser interacting directly with the wallet hardware, Trezor Bridge handles communication locally, ensuring secure data transfer while your private keys remain safely stored on the device.
Why Trezor Bridge Is Important
Using a hardware wallet without proper communication software can lead to connection issues or security risks. Trezor Bridge ensures:
🔐 Secure Local Communication
All communication between your wallet and browser happens on your computer, not through remote servers.
🛡 Protection of Private Keys
Sensitive operations are still confirmed on the Trezor device itself, meaning Bridge never has access to your private keys.
⚡ Stable Browser Compatibility
It ensures consistent performance across supported browsers when using web interfaces or online crypto tools.
How Trezor Bridge Works
Installed Locally
Trezor Bridge runs in the background on your computer after installation.
Connects Browser to Device
When you open a supported wallet interface or web app, the browser sends a request to Trezor Bridge.
Bridge Communicates with Wallet
The Bridge software forwards commands securely to your Trezor hardware wallet via USB.
User Confirms on Device
All sensitive operations—such as signing a transaction—must still be approved physically on the Trezor device.
This process ensures convenience without sacrificing security.
