# bisq2 contains a separate Java app which is used to scan Bitcoin Lightning QR codes.

# bisq2 communicates with the webcam app via a local TCP connection using a simple one-way protocol.

# Since the webcam app dynamically loads native code, this package is for maintainers to test QR code scanning without having to spend bitcoin to execute a trade.

# This package is exposed as an attribute of the bisq2 package; bisq2.webcam-app.
