Trezor Bridge is a program that allows your Trezor hardware wallet to communicate
with your browser securely. Download and install it to start using your Trezor device.
Trezor Bridge is a communication interface between your Trezor hardware wallet and your web browser. It enables secure data exchange without compromising your private keys or sensitive information.
When you connect your Trezor device to your computer, Trezor Bridge acts as a secure intermediary that allows web applications like Trezor Suite to communicate with your hardware wallet. This architecture ensures that your private keys never leave the secure environment of your Trezor device.
The Bridge runs as a background service on your computer, automatically detecting when a Trezor device is connected and facilitating the secure transmission of transaction data for signing. All cryptographic operations happen within the isolated environment of your Trezor hardware wallet, making it virtually impossible for malware or attackers to compromise your funds.
Select the version compatible with your operating system. Trezor Bridge is available for Windows, macOS, and Linux.
