On-chain payments
Our own index of USDC Transfer events on Base to this payTo, updated every 10 minutes — watching since 2026-09-14; earlier history is still being backfilled, so these figures cover 3 days, not 30. Base USDC only — a seller settling elsewhere reads as quiet here. These figures belong to the address, which 9 listings declare — they are not this route's alone, and must not be summed across listings. Methodology.
