Trezor Bridge is a small application that allows your Trezor hardware wallet to communicate with your browser. Without it, you wouldn't be able to connect to popular online crypto exchanges or wallets. Think of it as the translator between your physical device and the digital world of your browser. It provides a **secure channel** for your Trezor to sign transactions and manage your cryptocurrency assets.
The process is quite straightforward. First, you install the Trezor Bridge software on your computer. It runs in the background, consuming minimal resources. When you visit a website like MyEtherWallet or Trezor Suite, the site will detect the bridge and prompt you to connect your Trezor device. The bridge then facilitates the communication, allowing you to securely manage your cryptocurrencies. This seamless integration is a key part of the Trezor security model, which is designed to protect users from phishing attacks and other online threats.
One of the most important aspects of the Trezor Bridge is its **cross-platform compatibility**. It works on Windows, macOS, and Linux, ensuring that a wide range of users can benefit from its security features. The bridge also **updates automatically**, which is crucial for maintaining security and compatibility with new browser versions and cryptocurrency protocols. These updates are non-intrusive and usually happen without you even noticing. By using the bridge, Trezor ensures that your assets are protected and that you're always using the most up-to-date software.
