Connecting a hardware wallet to web-based cryptocurrency services should be fast, private, and secure — that’s where Trezor Bridge comes in. Trezor Bridge is a lightweight local application that enables safe communication between your Trezor device and web wallets or exchanges via your browser. Unlike browser extensions or direct USB access that can be blocked or outdated, Trezor Bridge runs on your computer and creates a trusted communication channel so web apps can request signatures, read public addresses, and confirm transactions — without exposing your private keys.
