Trezor Bridge is a lightweight background service that enables secure communication between your Trezor hardware wallet and browser-based cryptocurrency applications.
Download Trezor BridgeTrezor Bridge acts as a secure connection layer between your web browser and your Trezor hardware wallet. Because modern browsers restrict direct access to USB devices, Trezor Bridge ensures that your wallet can safely communicate with web-based tools without exposing private data.
Instead of relying on browser extensions or third-party plugins, Trezor Bridge runs quietly in the background on your computer. When a supported website requests access to your Trezor device, Bridge verifies the request and establishes a secure channel.
This design maintains strong separation between your hardware wallet and the internet while allowing smooth interaction with trusted services.
Trezor Bridge ensures encrypted communication between your browser and hardware wallet, preventing unauthorized access.
Once installed, Bridge runs silently without user interaction, activating only when a supported application is detected.
Trezor Bridge is available for major operating systems, providing consistent behavior across environments.
Trezor Bridge was designed to respect modern browser security policies while maintaining a high standard of wallet protection. It functions as a local mediator rather than a remote server.
You connect your Trezor hardware wallet to your computer using a USB cable.
A supported website or application sends a request to communicate with the device.
Trezor Bridge verifies the request and opens a secure local connection.
Sensitive actions require physical confirmation directly on the Trezor device screen.
Without Trezor Bridge, browsers would be unable to safely communicate with USB hardware wallets due to strict sandboxing rules. Bridge provides a controlled, secure workaround without weakening browser security.
This approach minimizes attack surfaces while preserving usability for decentralized applications, portfolio tools, and blockchain explorers.
Eliminates reliance on extensions that could introduce vulnerabilities or tracking risks.
All communication occurs locally on your device, never through external servers.
You remain in full control, approving all sensitive actions directly on the hardware wallet.
