About Trezor Bridge
Trezor Bridge is a small background application that allows communication between Trezor hardware wallets and supported browsers or native desktop apps. It replaces legacy browser plugins and improves compatibility while keeping the device communication secure and explicit.
All traffic is local. Bridge only exposes connection endpoints on localhost and requires explicit user interaction with the device.
Works with current versions of major browsers and Trezor Suite. No browser extension needed.
Official releases and checksums are published by SatoshiLabs. Verify installer signatures before installing.
