Relationships
x402 payments on Base · 19 October 2026 – 26 October 2026 · 8 days
No x402 payment reached this seller’s wallet on Base in the window, so it has no buyers to read relationships from.
Relationships are patterns in the x402 payments we observe on Base over the window: a buyer is a wallet that paid this seller’s payTo wallet, and came back means it paid on two or more different days. A wallet is not an agent, and a relationship is a pattern of payments, not a claim about who anyone is or who runs a wallet. Bought alongside and the switches leave out wallets that paid more than 30 sellers in the window: a wallet that pays everyone says nothing about what goes together.
Is this your service? See who your buyers are: every wallet that paid you, day by day, and where the ones that left went, in one report.
