Hosts paying into this wallet
How this is counted
- Sellers are the receiving wallets of every Base USDC route in Coinbase Bazaar's public catalog, re-read several times a day.
- A payment is a USDC transfer on Base into one of those wallets that used the payer's signed EIP-3009 authorization, the way x402 pays. Ordinary transfers and mints into the wallet are totalled apart. Everything is read from public RPC and bucketed by UTC day.
- Each payer gets one class per seller, in this order: seller-linked, paying ten or more sellers, campaign, then repeat or one-payment.
What this cannot tell you
- A payment here is a USDC transfer on Base that used the payer's signed EIP-3009 authorization, the way x402 pays. It is not proof that an HTTP 402 request caused it.
- Ordinary USDC transfers into the wallet are totalled apart and never counted as payments.
- A wallet with no flag is not proof of an independent customer: one operator can use many wallets.
- Funding is checked one hop only: USDC sent directly from the seller's wallet to a payer.
- Only wallets listed in Coinbase Bazaar with a Base USDC price are read.
