Get listed.
Get burned.
Nobody applies and nobody pays. Every 15 minutes INDEX screens every coin on pump.fun, StonkFun, Solana and Robinhood Chain. At each review (00:00, 06:00, 12:00, 18:00 UTC) the biggest coins that pass the screens take the seats. From the moment your coin is listed, every trade on its index buys it and burns it.
Liquidity, volume, holders, age, organic volume, a real pool behind the cap, mint and freeze revoked. The exact numbers are on every index page.
Eligible coins are ranked by market cap. Beat the smallest member by enough at a review and you take its seat.
Every hour your index's trading fees are split equally across its coins. Your share buys your coin on chain and burns it.
Members keep their seat while they rank inside the buffer and pass the (looser) maintenance screens.
