I want to make a simple mint frame that accepts erc20 payments for mints. Aiming for one click.

IMO the approval step adds confusion for first timers. 

Is there an elegant way to transfer an erc20 to a contract and then check that msg.sender has sent the appropriate amount before minting? 

All roads I've thought through so far lead to the check offchain. I'm ok with that but wondering if someone has done something similar and can help me out!

Daimo Pay solves this using intent addresses. Single transfer > any action.
