Grade any coin before you buy it
Paste an address or a pump.fun link. In a couple of seconds you get the six things that decide whether a coin can actually pay you out: who holds the supply, what your exit costs, how much sits above you, how far the curve still has to run, whether the same wallets keep buying, and how much of the volume is machines.
What the six numbers mean
How to read a grade
One letter, A to F, plus a score out of 100. It is a dump-risk read, not a price prediction: it tells you how badly the supply is stacked against you right now.
How the grade is built
The score comes from the pool’s own risk block: top-10 share, dev holdings, bundler wallets, insider wallets, sniper wallets, holders, age and the ratio of pool liquidity to market cap. Then hard caps override the score, because some things should never be averaged away:
What PumpCheck will not tell you
It will not tell you a coin is going up. It cannot see a callout from an account with a million followers, and it cannot see the intent behind a wallet. A coin can grade A and still go to zero because the deployer is patient. Grade is one filter, and it is the filter almost nobody else runs before they buy. It is not a reason on its own to put money in.

Questions
Is PumpCheck free?
Yes, and it stays free. The site earns from trading referral links when you choose to trade. The tools do not ask for a login, an email or a wallet connection, and they never have access to your funds.
Where does the data come from?
Live pool and trade data from SolanaTracker: holders, risk wallets, liquidity, market cap and the recent trade feed. Nothing is hand-entered and nothing is adjusted after the fact.
Why did a coin grade badly when it is clearly pumping?
Because pumping and being safe to enter are different questions. Coins that are being bought by bots and insiders pump hardest right before they dump. The grade is designed to be uncomfortable exactly at that moment.
Do you publish how your own calls did?
Yes. Every coin that appears on the Top 10 board is logged at the market cap it had at that second and tracked for 24 hours, and the record is shown on the homepage. Wins and disasters stay up.
Can I check a coin that already graduated?
Yes, any Solana token works, on the curve or on PumpSwap. Off-curve coins get graded on pool depth and supply instead of curve position.
PumpCheck is a risk read on a live data feed, not financial advice. Memecoins are extremely volatile and most go to zero. Never trade more than you can afford to lose. Some links on this site are referral links that support it.
