Payment shape (25 most recent sampled): 23 x402-signed (EIP-3009 transferWithAuthorization, the exact scheme's on-chain signature) · 2 plain transfers (a wallet paying the ordinary way) · 0 other calldata (facilitator batch, smart wallet, or unrelated — not classified).

Peak day 2026-09-04: 58 payments. Last indexed day 2026-09-05: 10. Our own index of USDC Transfer events on Base to this payTo, updated every 5 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 11 listings declare — they are not this route's alone, and must not be summed across listings. Methodology.
