How do you reverse that charge in case of accident or fraud?

ACH isn't great and RTP/FedNow are significant improvements, but there are reasons why reconciliation exists.

I’m not sure you can reverse a FedNow payment as it uses a good funds model. The same way you can’t reverse a wire and the only reversible allowable for ACH is for erroneous files/payments and unauthorized debits (not all fraud is applicable there).

Which is what happens when someone in charge loses money big time. Etherium Classic -> Etherium, LUNA->LUNC, etc.
