Trezor Bridge – Secure Communication for Your Trezor Wallet
Trezor Bridge is a lightweight background application developed by SatoshiLabs. It enables secure, encrypted communication between your Trezor hardware wallet and browser or desktop apps so you can manage transactions, view balances, and use dApps without exposing your private keys.
What Is Trezor Bridge?
Bridge acts as a mediator that translates and forwards requests between your browser or wallet application and your Trezor device. Because browsers differ in USB support, Bridge ensures compatibility and reliability across operating systems and browser environments.
Why Use It?
Ensures reliable device detection across browsers
Maintains stable USB communication without extension dependencies
Works locally and securely — private keys never leave the hardware
Supports firmware updates, passphrase input, hidden wallets, and more
Deprecation & Transition
Trezor is phasing out the standalone Bridge and consolidating its functionality within Trezor Suite. To avoid conflicts, users should uninstall legacy Bridge versions and rely on Suite’s integrated communication layer. :contentReference[oaicite:20]{index=20}
