That’s not even the best part. For most of those transfer services, you have fuck all for protection. From the bank’s perspective, you authorized transfers between your account and whatever service. The transfer from your bank to the third party middle man is mostly indisputable. Those third parties provide shit protection for consumers since they’re not held to any of the dispute related regulations like Regulation E. Accidentally send the wrong person a transfer through zelle? Get scammed buying a puppy on Cash app? Ripped off on an eBay sale through PayPal? Get fucked, that’s your problem.
