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 deployer history specifically, written for a first-time buyer.
Run a free check How we scoreA wallet with a trail of failed launches is a pattern worth knowing about, and also easy to hide by launching each token from a fresh wallet.
CoinCheck reports a serial-launcher signal for launches it observed and marks it as weak evidence.
A clean history proves very little, and a deployer rotating wallets each launch is invisible to it. That is why there is no deployer score yet: a score without a defensible rubric would be theatre.
You do not need to understand pool mechanics to check whether a token can be exited. 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.
