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

Top 10 walletsThe share of supply the ten biggest wallets hold. High means someone can dump on you whenever they like. We also show it in dollars, because a percentage hides how much money is actually waiting to sell.
Bag above youDollars held above your entry price. If it is larger than the depth under you, you are exit liquidity, no matter how good the chart looks.
Cost to sell $500What a $500 exit does to the price in the pool. Under about 2.5% is cheap. Over 6% and you are paying a tax to leave.
Curve positionHow far along the bonding curve the coin is, and roughly how long it takes to graduate at today’s pace. A slow curve with a big crowd above you is a trap.
Repeat buyersHow many wallets bought three or more times in the recent trade feed. On this market it is the closest thing to a real signal: people come back when they are making money.
Bot shareThe slice of buying routed through trading terminals and bots. Heavy bot flow means the move was manufactured, and manufactured moves stop the second the bots rotate.

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.

AClean book. Rare on this board. Small top-10 share, real pool depth, and an exit that does not punish you. Still can go to zero, it just does not have an obvious executioner.
BStructurally sound, still crowded. Nothing fatal. Usually one soft spot: a held bag, a thin pool, or a curve that is already 90% done.
CAverage coin, average odds. Mixed supply and thin liquidity. Fine to watch, not where size belongs.
DThin. Either the pool is shallow relative to the market cap, or the top wallets hold enough to erase the last hour in one sell.
EHeavy bag above you. Insiders, bundlers or snipers hold a meaningful share. You are buying their exit.
FExit liquidity. Pool drained, supply concentrated, or the float is so thin that your own buy moves the price more than your sell can recover.

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:

Pool under $5,000Capped at F. There is nobody left to sell to.
Graduated with under $15,000 of liquidityCapped at E. Graduation is not depth.
Pool smaller than 10% of market capCapped at D, and at E under 5%. A big market cap over a shallow pool is a paper number.
Too new to measureNo grade at all rather than a fake one. A coin that is 40 seconds old has no history to read.

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.

How to actually use it

1. Grade before you buyNever after. Most bad entries are decided in the ninety seconds people spend looking for the contract address.
2. Check the exit firstIf the cost to sell $500 is above 6%, the rest of the numbers barely matter. Size down or skip.
3. Watch for driftGrades move. A coin that was B at $30K can be D at $120K when the float thins. Check it again before you add.

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.
