Trezor Bridge® | Connect Your Trezor to Web Browsers Securely
Trezor Bridge® is the official connectivity tool that enables communication between your Trezor hardware wallet and supported web browsers. Without Trezor Bridge, your browser cannot properly detect your Trezor device, meaning that secure crypto transactions, wallet setup, and app integrations would not function correctly.
Whether you use Trezor Model T or Trezor Safe 3, Trezor Bridge plays a crucial role in accessing Trezor Suite Web, decentralized applications, and secure browser-based services — all while keeping your private keys completely offline and protected by the hardware wallet.

Trezor Bridge runs silently in the background, ensuring secure and transparent connectivity without requiring browser plugins or extensions.
