68 x402-style payments from 2 distinct payers, $1.57 USDC in the last 7 days (Base, exact read)

Payments: 68
Payers: 2
USDC: 1.57

All USDC received at this payout address: $1.57 (includes payments that are not x402)

Reading: x402-style payments to this payout address on Base, exact read of the 7 days to 2026-10-19, 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.
