About Trezor Bridge
Trezor Bridge is a small background service that allows communication between your hardware wallet and your computer. It ensures Trezor Suite or browser extensions can detect your Trezor without issues, creating a secure and stable communication channel.
Bridge replaces outdated browser plugins and ensures compatibility across modern browsers like Chrome, Firefox, and Edge. It automatically detects your device and provides live connectivity without extra setup steps.
