#webxdc is a shared spec and joint impelemntation with eg #cheogram and #monocles ... It has nothing to do with proton. Webxdc apps are shared in a chat and run inside the messenger. Proton does not have a messenger. Webxdc apps work on all platforms that #webxdc messengers are released for, including @deltatouch , an Ubuntu based phone. DeltaTouch runs all webxdc apps including the realtime p2p ones. @lk108 is doing an incredible job :)
