Stablecoins and FedNow instant payments are options. Walmart is about to offer Pay by Bank using FedNow instant payments rails to avoid credit card interchange fees, for example. Does Coinbase offer payment processing yet? Could be the next Superapp competing against PayPal’s global digital wallet.
Visa and Mastercard are for profit companies. Harder for commercial banks and the Federal Reserve to block payments unless you’re straight up breaking the law or KYC/AML.
(payments are adjacent to my day gig, and I have to talk to FiServ and other FIs occasionally on the topic of moving money at a fintech)
