2801 x402-style payments from 99 distinct payers, $52.07 USDC in the last 7 days (Base, exact read)

window ended 2026-10-08

Payments: 2,801
Payers: 99
USDC: 52.07

All USDC received at this payout address: $52.08 (includes payments that are not x402)

Reading: x402-style payments to this payout address on Base, exact read of the 7 days to 2026-10-08, every block of the window: counted when the transaction carries a signed USDC authorization (EIP-3009), the settlement x402's `exact` scheme uses. Some non-x402 gasless sends use it too; Sato Hub's own payer wallets are left out

One seller wallet, each chain read on its own. We never send a payment, so we never observe what a paid call returns. Unknown means we hold no reading, not that anything failed.
