Perhaps one example is Endaoment[1], which automatically converts ETH payments to USDC to mitigate market volatility and ensure beneficiaries receive donations in dollar amounts. This is also good from a tax perspective, as businesses report income based on the USD price of an asset at the time it is received, not based on the price of that asset later when it may be disposed.

Also see Stripe USDC payouts[2]. Some users may prefer this to receiving payments in a PayPal account.
