The essential communication tool that enables your Trezor hardware wallet to securely interact with web browsers and Trezor Suite. Download, install, and troubleshoot Trezor Bridge® with our comprehensive guide.
Understanding the crucial role of Trezor Bridge® in securing your cryptocurrency transactions
Trezor Bridge® is a lightweight background service that enables secure communication between your Trezor hardware wallet and web browsers. It acts as a vital intermediary, translating browser-based requests into a format that your Trezor device can understand and process.
Unlike browser extensions that might pose security risks, Trezor Bridge® runs as a separate application on your computer, providing an additional layer of security by isolating the communication channel from potentially compromised browser environments.
When you connect your Trezor device to access web-based wallet interfaces like Trezor Suite Web or connect to third-party services, Trezor Bridge® facilitates this connection through the following process:
Your browser sends a request to communicate with the connected Trezor device through Trezor Bridge®.
Trezor Bridge® translates the browser request into a format your Trezor hardware can process securely.
The translated request is sent to your Trezor device, which processes it while keeping private keys isolated.
