On-chain payments
Payment shape (6 most recent sampled): 0 x402-signed (EIP-3009 transferWithAuthorization, the exact scheme's on-chain signature) · 0 plain transfers (a wallet paying the ordinary way) · 6 other calldata (facilitator batch, smart wallet, or unrelated — not classified).
Peak day 2026-09-25: 1 payments. Last indexed day 2026-09-25: 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. Methodology.
