What is a rug pull? A plain definition and how to spot one early
What a rug pull actually is, the forms it takes on Solana, the on-chain signals that appear before one, and what creators should avoid doing accidentally.
A rug pull is when the people behind a token deliberately take value from the people who bought it.
Not a coin that failed. Not a chart that went down. Something specific and intentional, and the distinction matters because these words get used interchangeably by people who lost money either way.
The forms it takes
Three shapes cover almost everything you'll encounter.
Liquidity removal. The classic version. Creators provide liquidity, buyers arrive, then the creators withdraw that liquidity and the token becomes unsellable for everybody holding it, which on a token where a team controls the pool directly takes one transaction and about 4 seconds.
The dump. Creator holds a large share, buyers arrive, creator sells everything into them. Price collapses, the creator has the SOL, and technically nothing was withdrawn from anywhere.
The honeypot. Contract mechanics prevent selling. Buys work, sells fail, and the trap is baked into the code before anybody arrives.
What's possible on Pump.fun specifically
Precision matters here, because the bonding curve changes the picture.
Liquidity removal mostly isn't available. The curve holds SOL programmatically and nobody withdraws it manually, so the classic version doesn't apply while a coin sits pre-graduation. The bonding curve guide covers why.
What remains available is the dump. A creator who took a large share at launch can sell it into whoever arrives, and the effect on buyers is identical to any other rug even though the mechanism differs.
After graduation the picture widens again, since a pool exists and pool mechanics reintroduce some of the older patterns.
Signals that appear beforehand
Can you see one coming? Usually. Most of these show up in about 3 minutes, and buyers who bother to check are checking exactly these.
Concentration. How much sits in the top 10 wallets? One address holding 30% is one decision away from being the entire chart.
Creator behaviour. What has the creator wallet done? Any selling at all, at any point, is the loudest signal available and it never goes away.
Connected holders. Do the top wallets trace back to a common funder? Bubblemaps and holder analysis covers what those clusters look like.
History. What else has this creator wallet launched, and how did those end? A wallet with 6 previous coins that all went to 0 is telling you something.
Sell testing. Can people actually sell? A coin where sells fail while buys succeed is a honeypot regardless of what anybody says.
What creators do accidentally
Now the part most guides skip, and it matters if you're launching rather than buying.
You can produce every signal of a rug without intending any of it. Take too large a dev buy and your wallet sits in the top 3 holders permanently. Sell some of it during a dip because you needed the money, and you've now sold into your own launch, permanently, with a timestamp. Fund a few wallets to make the coin look alive and they draw as a star on a clustering map.
None of that requires bad intent, and every bit of it reads identically to somebody checking your coin at 2am with a clustering tool open in the next tab. The chain records actions, never motives.
Which means the practical advice is behavioural: decide before minting what your dev buy will be and whether you'll ever sell it, and then don't improvise at 3am. How much should a dev buy covers the trade-off.
The unfair version
Plenty of creators get accused of rugging when what actually happened is that nobody ever found the coin.
A flat chart with 6 holders isn't extraction. It's a launch that never entered the surfaces where people browse, which is a distribution failure rather than a moral one. Reading a stalled launch covers how to tell them apart, and the difference is worth insisting on.
Three checks before buying anything
- Top 10 holder concentration, and whether they're connected
- What the creator wallet holds and has ever done with it
- Whether sells actually execute
Three minutes. It won't catch everything, and it catches most of what's worth catching.
Frequently asked
No, and the conflation is unfair to a lot of people. Most coins fail because nobody found them. A rug involves the creator deliberately extracting value from buyers, which is a different thing entirely.
Not by pulling liquidity, since the curve holds it programmatically. What a creator can do is dump a large holding into buyers, which produces the same outcome for them.
Look at holder concentration, whether the top wallets are connected, and what the creator wallet has done. Three checks, about 3 minutes, and they catch most of it.
Everything in this guide describes mechanics that settle on Solana mainnet, so you can check any of it yourself. Mint addresses, swap signatures, curve progress and wallet counts are all public, and an explorer will disagree with us if we are wrong.
Curvegrad sells a volume service, and guides that touch on what a campaign does say so in the text rather than in a footnote.
