If you use PayPal, Venmo, and Cash App, you already know the friction: you need the same app as the person you’re paying, or the money doesn’t move. That’s not a permanent feature of how payments work. It’s a gap that’s closing.
The same problem the early internet had
In the early days of email, you needed an account on the same provider to reach someone: AOL to AOL, Yahoo to Yahoo, Hotmail to Hotmail. There was no protocol that let those systems talk to each other. Email fixed that with a shared standard that let any provider interoperate with any other. Payment apps are stuck at the pre-standard stage right now. At its core, cross-network settlement infrastructure does for payment apps what that shared protocol did for email: it lets fundamentally different providers settle transactions with each other in real time, without either side needing to be on the same platform.
Why “instant” currently costs money
When you get paid through one of these apps, you’re typically given two choices: move the money to your bank instantly for a fee, or wait two to three days for it to settle for free. That delay isn’t arbitrary. It reflects how long it actually takes to settle to a bank account through existing rails. The app pre-funds your instant transfer and charges a fee to cover the risk it’s taking on by fronting you the money before settlement actually clears.
What changes once these networks interoperate
Once payment providers can settle with each other directly and in real time, that two- or three-day wait, and the fee you pay to avoid it, both start to go away. You’d be able to send money from Cash App to Venmo, or Venmo to Zelle, or Zelle to PayPal, with the transfer settling close to instantly and at a small fraction of today’s instant-transfer fees. The practical effect is that money moves faster through the economy: the velocity of money increases when people aren’t waiting days for funds to clear, and that has knock-on effects well beyond just convenience for individual users.
