Woah, neat! It seems like we had pretty similar thinking for the kinds of workflows you'd want.

It looks like you have an Venmo integration ("Sent to Venmo" in screenshots) which I haven't quite cracked yet - curious if you're willing to talk about how it works. Tender has venmo via plaid, but it only supports importing tx, not initiating payments/requests.

I thought about either: integrating unofficially (https://github.com/mmohades/VenmoApiDocumentation) or just doing links to venmo payment (i.e. venmo.com/user?pay=500) and having some way to import venmo contacts

Neither seems great from a UX or security perspective.
