Trezor Bridge — Secure Connection for Your Trezor
Introduction to Trezor Bridge
Trezor Bridge is essential software developed by SatoshiLabs to enable secure communication between your Trezor hardware wallet and desktop or web applications. Acting as a secure USB-to-web bridge, it ensures all commands and transaction data processed through your wallet remain safe and trustworthy.
Designed for enhanced security and user-friendliness, Trezor Bridge replaces legacy connection methods by offering automatic device detection and cryptographically verified communications.
