I'd like to help on the UX. I think this is exactly what has been needed for a while. I have time to commit to this effort if you are open to it. I spent a little bit of time helping with the graphene-ui, but I don't think I helped much because the effort was fragmented across a lot of different players. I use the cash app extensively and think that there is a market for people sending bitUSD seamlessly to one another.
