Method

Four areas, nine metrics, measured from each coin's full on-chain history. Updated every day at 06:00 UTC with the previous full day.

Conviction, 50%

  • Drawdowns survived. How many past drawdowns today's holders sat through, with bigger falls counting for more.
  • Supply held. How much of the supply stays in the same wallets week to week.
  • Fullported holders. How much of the supply sits with holders who are heavily concentrated in this coin.

Demand, 25%

  • Holder growth. Whether the number of meaningful holders is rising or falling.
  • Whale accumulation. Whether the largest holders are adding or trimming.
  • Dip absorption. How much buying met the selling during recent dips.

Market health, 12.5%

  • Holder concentration. How much of the supply sits with the largest holders. Lower is better.
  • Liquidity for its size. DEX liquidity compared with coins of a similar size.

Attention, 12.5%

  • Attention for its size. Social activity around the coin, relative to its size.

Scoring

Every metric is scored 0 to 100 against a fixed reference, so a score today compares with a score next month, and adding a coin never moves another coin's score. An area is the average of its metrics, and the index weights the areas as shown. A coin without attention data is scored on the other three areas. Memes and infra tokens (launchpads, revenue and utility tokens) are ranked on separate tabs, with the same method and scale.

Young coins

New coins are scored conservatively on the time-based metrics for their first weeks, until their history builds up. Their age is shown next to the name. Missing history never raises a score.

What counts as a holder

Balances are rebuilt from on-chain activity. Pools, contracts, exchanges, burn addresses, locked supply and automated trading wallets are left out.

Every day

At 06:00 UTC the index adds the previous day, recomputes every metric and runs quality checks. If a check fails, nothing is published and the last good day stays up.
