What you get
Disaster probability
Tree-model estimate that a token loses more than 50% within two minutes of its 10th trade, with the top factors that drive it.
Transparent flags
Wash-like churn, very few distinct buyers, serial creators, copycat names. Each flag comes with evidence and the weights are published.
Similar-history stats
For comparable past tokens: share that lost more than 50%, share that reached +50%, median net return after costs.
Wallet statistics
Trade history from a weekly ledger and whether a wallet's past results persisted. Statistics only, never a recommendation.
How well does it work?
Measured on a later period that was not used to build the score (50,652 tokens, base rate 24.9% lose more than 50%). Model v2 AUC: 0.88.
| Band | Share losing >50% | Median net return |
|---|---|---|
| LOW | 6.2% | -7.5% |
| MEDIUM | 31.2% | -33.6% |
| HIGH | 69.0% | -81.5% |
LOW does not mean safe: about one token in sixteen still lost more than half. The score reduces risk; it does not remove it.

Limits you should know
- Pump.fun only, history covers roughly mid-September to early October 2026, plus live recordings.
- About half of tokens have no observable 2-minute outcome and are excluded from the statistics, so loss rates are probably understated.
- Market regimes change; the score may degrade and is re-validated periodically.
- Live data is refreshed periodically, not in real time. The wash-trade detector is the dominant signal.
- Not financial advice, not a price prediction, not a trading signal or copy-trading service.
