1. Wash trading
The biggest distortion. Because x402 payments are cheap and permissionless, a seller can loop USDC between its own wallets to manufacture volume and climb explorer leaderboards. A late-2025 wave pushed reported volume past $3M in a single day; independent analysis (Artemis) found the large majority of that era’s activity was gamed, and the wallets behind it have gone quiet.
2. Dust
Tens of thousands of wallets receive sub-cent payments — automated spam, testing, and airdrop-style loops. They inflate the “number of sellers” enormously (the median wallet earns cents per month) while adding almost nothing to real revenue. An average-payment floor removes them.
3. Facilitator settlement wallets
Facilitators (the services that verify and settle x402 payments) often route aggregated flows through a single wallet. Raw explorers then rank that wallet as the top “seller” — but its balance is other people’s revenue passing through, not its own. We identify and exclude these (Meridian, RelAI, FluxA today).
What’s left is the real market
Filter all three and you get the organic figure: the volume and seller count that reflect actual businesses being paid by actual buyers. It’s smaller and less exciting than the headline — and it’s the number worth tracking. See it live on the dashboard, the exact rules on the methodology page, and the monthly read in State of x402.
