Take a look at any of the defi providers and you'll see that there is a lot of money floating around in pure crypto payment infrastructure. If you're not in the defi world, you could pick https://curve.fi as a good example because you might have heard of uniswap but probably haven't heard of curve. I see on their website that the weekly volume of deposits and withdrawals to their liquidity pools is $7bn. All done on solidity, no direct payments infrastructure at all. If you looked at any of the others (aave, balancer, yearn) you would mostly see a similar story. People who onramp and offramp to fiat currencies and therefore handle real money are actually in the minority.

As a tangential aside we wanted to be able to handle crypto and real money payments for something so actually used stripe for credit cards and "coinbase commerce" who offer a stripe-like slick checkout experience and api for accepting crypto payments. The only real downside to the coinbase checkout that we've found is that the blockchains take long enough to accept transactions and the price fluctuates enough that you constantly get people under or overpaying by very small amounts that are expensive to deal with. Still not sure what if anything to do to elegantly handle this.
