Leaderboard of x402 sellers by observed USDC inflow, with distinct payers, an HHI concentr
Leaderboard of x402 sellers by observed USDC inflow, with distinct payers, an HHI concentration measure and wash-risk flags. Sellers below the observation floor are returned unrated, not accused. The payer-graph discount applies only where wallet scan coverage supports it. HHI measures concentration, not common control.
