What's the best crypto + fiat checkout out there?

So want users to be able to choose if they want to pay with their credit card or connect wallet and do a crypto tx.

Tested Coinbase Commerce but it seems limited.

Try https://3cities.xyz/#/pay-link

It's decentralized and free, with no fees, no API keys, no sign ups, and no tracking.

It supports multiple currencies including ETH and USD, and 6 tokens and 7 chains, with many more coming soon.

The app searches the buyer's wallet for the best token and chain to pay.
