Peak day 2026-09-06: 22 payments. Last indexed day 2026-10-04: 1. Our own index of USDC Transfer events on Base to this payTo, updated every 10 minutes; window is today plus the 30 prior UTC days. Base USDC only — a seller settling elsewhere reads as quiet here. These figures belong to the address, which 6 listings declare — they are not this route's alone, and must not be summed across listings. Methodology.
