The FraudCoins dataset

We publish a daily, automated measurement of how concentrated each crypto asset’s supply is among its largest holders — the signal that makes single-hand price control possible. It is free to use with attribution.

Field definitions

top10Pct number (0–100): Share of total supply held by the ten largest holding addresses, after excluding burn/null addresses and wallets labelled as exchange, staking, bridge, treasury or liquidity-pool contracts. Unlabelled contracts are retained, because team and vesting multisigs are contracts.
flagged boolean: True when top10Pct ≥ 50% and the asset is not on the manually-reviewed exclusion list. A flag is an automated, opinion-based risk indicator — not an allegation of wrongdoing.
riskScore integer (0–100): Composite score from weighted factors: ATH drawdown, volume/market-cap ratio, market-cap size, supply structure (free float), 24h volatility, verified holder concentration, and transparency gaps.
holdersSampled integer: Number of holder records examined for that measurement. Readings below 50 do not update stored peaks.
asOf / measured date ISO 8601 date: The UTC date the measurement was taken. Every published figure is tied to the date it was measured; we do not carry values forward.
pageState enum: currently-flagged · recovered (previously exceeded the threshold, no longer does) · monitored · dormant · gone (delisted upstream).

Limitations you should quote alongside the data

Concentration is a risk signal, not proof of wrongdoing. A young legitimate project and a manipulation token can show identical numbers.
We only measure EVM-compatible tokens on seven chains. Native assets (e.g. Bitcoin) are not holder-scanned.
On-chain wallet labels are imperfect; an unlabelled exchange wallet may be counted as a private holder.
Absence of a flag is not a safety guarantee.
