Trezor Bridge is a crucial application that allows the Trezor hardware wallet to communicate with the Trezor web-based interface (Trezor Wallet or older versions of Trezor Suite Web). It acts as the secure intermediary, ensuring seamless connection and secure transaction signing.
Your Trezor device uses a communication protocol (USB HID) that modern web browsers cannot directly access for security reasons. The Bridge serves as a local proxy, facilitating this secure communication without compromising the private keys stored on your device.
By routing the communication through a trusted, signed application installed locally, the Bridge adds a layer of security, ensuring that only authenticated applications can request data from the Trezor.
It ensures compatibility across different operating systems (Windows, macOS, Linux) and browsers, making the Trezor experience consistent and reliable.
