How are remittance platforms enabling 24/7 settlement when US banks are still closed on weekends???

This keeps coming up when we discuss how to enable 24/7 remittance for our product and I can never get a clean answer. On the surface "24/7 transfers" sounds like a simple marketing promise but the mechanics are genuinely complicated when your on-ramp depends on ach or fednow and your banking partner has weekend cut-off windows

From what I can tell the platforms that actually deliver on this are the ones where the stablecoin settlement layer handles the "always on" part and the fiat on-ramp batches or queues intelligently so users don't feel the gap. But if you're holding customer funds over a weekend while waiting for the next bank window that creates its own compliance and float questions depending on your licensing setup. How are teams actually solving this in production? Is it purely an infrastructure choice or is there a licensing and banking relationship piece that most articles skip over?
