Why Trezor Bridge matters

Web browsers and operating systems change—Trezor Bridge provides a controlled, signed, and audited transport layer between modern browser sandboxing and the sensitive operations that must remain on the hardware wallet. When you install Trezor Bridge, you get a secure gateway that protects your keys, supports transaction signing, and provides predictable integration points for developers and end users.
