Some XMR dude gave me grief that we didn’t have a private way to send private ZEC requests to each other. So myself with claudius help made a strong one.
All shielded. Encrypted in browser so your info and memo remains private, No logs. Invoice expires whether it’s paid or not when the countdown hits zero & gets destroyed leaving zero trace.
Give it a try or a test out if you want someone to pay you direct in ZEC. Just add your shielded wallet, set the amount, add a private memo (only who pays sees it), pick when it expires (hours or days) click generate, then send them the link or the QR you get & monitor your own wallet. Simple.
If you use and find it useful, please comment here and thanks 
currently thinking how it could verify payment but without having to ask for someone’s viewing key, is there even a way 
also will be linking to one secret email api so you can instantly email the encrypted link and that email destroys after being viewed once
