Stablecoin settlement is pretty interchangeable.
Issuers and acquirers can choose among multiple networks. Consumers use whatever is easiest for them. In all cases, you can move money 24/7.
The interesting parts are liquidity, compliance, routing, reconciliation, and distribution. Without those components, settlement doesn't achieve much.
So figuring out how to execute on those aspects on open settlement rails is the actual challenge, and it is only achievable when you welcome all of them, like we've done with the Open Money Stack.
