Download the Latest Trezor BridgeThe **Trezor Bridge** is a lightweight background application designed to solve a fundamental technical challenge: allowing web browsers and desktop applications (like Trezor Suite) to communicate with a **USB device**—your Trezor. Because browsers are sandboxed for security, they cannot directly access low-level USB drivers.
The **Bridge** acts as a localized, trusted communication hub. It runs as a small server on your machine, listening for requests only from the **Trezor Suite** (or the deprecated Trezor Wallet web interface). When Trezor Suite needs to talk to your hardware wallet, it sends the request to the Bridge, which then handles the direct USB communication. This entire process happens locally, ensuring no sensitive data is transmitted over the network.
Without the **Trezor Bridge**, managing your **cryptocurrency** would be difficult or impossible on many operating systems. It standardizes the connection, ensuring reliable device recognition and stable transaction signing. It ensures that the critical signing and confirmation processes can reliably and instantly pass information between the **Trezor device** and the software interface, maintaining the strict **cold storage security** protocol.
For users prioritizing **crypto security** and a frictionless experience with their **hardware wallet**, the Bridge is an indispensable utility.
