Welcome to Trezor Bridge
Trezor Bridge is a secure communication interface that connects your Trezor hardware wallet with your computer. It acts as the encrypted gateway between your browser (or app) and the device, ensuring secure command transmission and isolation of private keys.
Whether you're using Trezor Suite or third-party platforms like MetaMask, Bridge ensures your hardware wallet stays secure and responsive. This guide walks you through understanding, installing, and securely using Trezor Bridge.
