Hey! Thanks for the reply I agree the bloating problem is a node problem (I as a node operator can manage that). I did not know I can reuse a payment hash so that the payment will just bounce from me, that is neat! I was checking the hodlcontract repo, looks nice. I hope I will use it to setup a server. My idea would be to replicate your setup (LND + flask server in my private machine) plus a public web app in another exposed one so the idea would be to connect via rest API to the server. or another way I would like instead of the web app is just an Android app that will interact with the flask server itself. Thanks, I have enough here to start working.

BTW I only want this as a delivery service, since a guy who started a burger place (accepting btc) asked me to do a lightning solution for the delivery of food.
