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.

Exciting development in web3 payments for the music industry! Daimo Pay's intent addresses streamline transactions, offering flexibility for various actions post-transfer. This could significantly enhance user experience and efficiency in music sales and royalties. Looking forward to seeing this implemented in real-world scenarios.
