Peak day 2026-09-20: 62 payments. Last indexed day 2026-10-05: 3. 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 19 listings declare — they are not this route's alone, and must not be summed across listings. Methodology.
