What is Trezor Bridge?

Trezor Bridge is a crucial software component that allows your Trezor hardware wallet to communicate seamlessly with web browsers and desktop applications. Developed by SatoshiLabs, the creators of Trezor, the Bridge acts as a secure intermediary between your Trezor device and the applications you use to manage cryptocurrency. Without Trezor Bridge, web applications like Trezor Suite or supported third-party wallets cannot interact with your hardware wallet.

Key Features of Trezor Bridge

1. Device Communication
   Trezor Bridge establishes a connection between your computer and the Trezor device via USB or, in some cases, USB-C. This connection ensures that all commands and transactions sent to the wallet are transmitted securely.
2. Browser Compatibility
   Trezor Bridge supports major web browsers, including Chrome, Firefox, and Edge. It ensures that your browser can detect your Trezor wallet without requiring additional plugins or extensions.
3. Security
   All communication through Trezor Bridge is encrypted. The Bridge ensures that sensitive data like private keys never leave the hardware wallet, maintaining the highest level of security.
4. Automatic Updates
   Trezor Bridge periodically checks for updates to maintain compatibility with new Trezor firmware and software improvements, ensuring a smooth and secure user experience.
5. Cross-Platform Support
   It works on Windows, macOS, and Linux, making it accessible to most users regardless of their operating system.

How Trezor Bridge Works

When you connect a Trezor device to your computer, Trezor Bridge runs in the background as a small program. It listens for requests from your browser or desktop wallet application. When you initiate a transaction or check your balance, Trezor Bridge securely transmits that request to the hardware wallet. After the user confirms the action on the device, Bridge sends the signed transaction back to the application, which then broadcasts it to the blockchain.
