● verified · data.other · 0.1 USDC/call · base, solana

Sign-time risk verdict for a destination or spender before value moves. Registry + ScamDB lookups plus at most one RPC call (approve spender code check), so it answers in milliseconds instead of running a full scan. Same verdict as the subscription REST API.

Peak day 2026-09-25: 40 payments. Last indexed day 2026-10-08: 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 10 listings declare — they are not this route's alone, and must not be summed across listings. Methodology.
