FedNow, RTP, and the new default for fintech settlement
Instant rails are no longer optional for advance products. How originators should architect around FedNow, RTP, and sponsor-bank cutoffs.

Payments & lending
Same-day ACH was the ceiling for a decade. FedNow and RTP moved the floor to seconds — but availability, limits, and return windows still vary by institution.
Fintech originators need a routing layer that selects rails by cost, speed, and recoverability — not a single hard-coded path. We model each outbound as a state machine with explicit timeout and repair transitions.
Sponsor banks remain the constraint. Treasury teams should negotiate cutoffs, prefunding, and exception queues before marketing instant money movement.
The winners treat payments as product infrastructure, not a vendor checkbox.
