The essential link for a seamless and protected experience.
Trezor Bridge is a vital application that runs locally on your computer, enabling secure communication between your Trezor hardware wallet and the Trezor Suite web interface. Without it, the browser wouldn't be able to directly communicate with the device. This dedicated layer of software ensures that all critical connection processes are handled outside of the browser, minimizing exposure to potential web-based vulnerabilities.
It acts as a lightweight, persistent daemon that listens for requests from the web wallet, translates them into USB commands for your Trezor, and securely relays the responses back. This architecture is crucial for maintaining the **air-gapped security model** of hardware wallets, ensuring that private keys never leave the device. The connection is authenticated and encrypted end-to-end.
By bypassing the standard, sometimes unreliable or slower, WebUSB API in favor of a dedicated application, the Bridge offers **superior performance and rock-solid reliability**. Every interaction, from checking your balance to signing a complex transaction, benefits from this specialized, secure pipeline. Installation is fast and integration is automatic, providing a truly effortless path to managing your digital assets with the highest standard of security available.
