Trezor Bridge — Secure Browser Communication for Your Trezor Hardware Wallet
Trezor Bridge is an official communication tool that allows your Trezor hardware wallet to connect directly and securely with supported web browsers and trusted cryptocurrency applications. Without Trezor Bridge, your browser cannot detect the hardware device or authorize crypto transactions via the Trezor interface.
Designed to protect your private keys and guarantee safe interaction with blockchain networks, Trezor Bridge acts as the secure link between your offline device and online services — maintaining full security every step of the way.
