pump.fun is launch on a bonding curve before graduating to an AMM pool. The window between listing and exit is minutes, not days. This page is about liquidity specifically, written for an automated trader.
Run a free check How we scoreThe number that decides whether a bad outcome is survivable is exit depth: how much supply sits inside a pool you could actually sell into. A chart can look healthy while every position in it is unsellable.
Buys under 1,500 dollars of usable depth are refused, and zero is refused outright, because a buy you cannot sell is not a trade. Sells are never gated.
If liquidity cannot be read the trade is allowed and flagged. Unknown never silently becomes zero.
If a bot is placing the order, the check has to be a single fast call that returns evidence rather than a dashboard. A check that returns a count of red flags, the on-chain reason for each, and an explicit list of what could not be read, is usable in a way that a single opaque score is not.
What these numbers are. CoinCheck's 94.6% aggregate is a bonding-curve graduation predictor over 79,519 resolved calls. It is not a rug-detection accuracy rate, and the bullish bucket scores 1%. Cross-chain wallet clustering and LP-unlock alerts are not built.
Fees. CoinCheck adds no trading fee of its own. The venue still charges its own on-chain trading fee, and we will not call that "no fees".
Independent. No paid promotion anywhere on CoinCheck. No ranking is bought.
