About this tool
A Carfax report for NFT collections, read directly from the chain: mint supply, unique holders, ownership concentration with a plain-verdict, wash-trading heuristics computed from actual transfer patterns, and whether activity is increasing or dying. Everything an agent needs before its human spends money on an NFT.
Frequently asked questions
Does a low wash score guarantee genuine trading?
No — the heuristics detect common wash patterns (self-transfers, back-and-forth flows) in recent history. Sophisticated wash trading across many fresh wallets can evade them.
Does it include floor price and marketplace listings?
No — floor data requires marketplace APIs. This report is deliberately chain-only: ownership, concentration and activity are the parts that can't be manipulated by listing prices.
