The instant scheme is the retail product (alias + 24/7), not an overlay on SCT Inst. Samples: Pix (BR), UPI (IN).

Scheme Instant A2A scheme (Pix, UPI)

Read the numbered story first. The switches change the situation. When a step is clear, open a technical trace to see the messages banks send.

How it ends

The money arrives, the other bank refuses, nobody answers in time, or a bank later asks to reverse a credit (recall).

Actor labels

Plain names (Payer / Beneficiary), ops shorthand (Orig / Bene), or ISO account sides (Dbtr / Cdtr). On SDD the creditor is Orig.
