Who buyers come back to

Every x402 seller on Base, ranked by payer wallets that come back on another day, not by money. 13 October 2026 to 19 October 2026.

Money can be made by one payer, or by a wallet paying a seller again and again. So this list counts payer wallets that come back on another day, not dollars. A wallet is not a customer you can see: one operator can run many wallets, and this list cannot tell. Read it as a lead, not a verdict.

Payer wallets: wallets that paid the seller this week. A wallet that paid 20 or more different sellers is a robot and is not counted (18 this week); its money still counts.
Came back: payer wallets that paid on 2 or more days.
Top payer: the share of the seller's USDC from its largest payer. Over half, and the row is marked one payer is most of it and placed after every seller that is not.
Shape of the money a day: flat every day within 10% of the middle day; spike one day over half the week; gone quiet the last two days near nothing after a $20 day; ramping up on each of the last 3 days; uneven anything else.
A wallet is not a person, and nothing here says who holds or runs one.

What kind of seller is each one? Free seller profiles: the type, read from its own payments, and its three priorities.

For agents: board.json holds the same numbers for every ranked seller, with its category and what it sells.
