A rug often shows before it hits.
A rug pull is when a coin's creators (or wallets linked to them) dump their tokens all at once and crash the price. On pump.fun there's no liquidity to pull on the curve: the rug happens through massive sells. You can't dodge them all, but you can spot many and limit the damage on the rest.

How a rug happens on pump.fun
- The dev sells: they bought big at creation and dump once others are in.
- The wallet group: the dev buys through several fresh wallets funded from the same source to hide their share. These « ruggers » sell together.
- Fake hype: coordinated buys pump the coin to lure buyers, then everything gets sold.
Warning signs
| Sign | Why it should worry you |
|---|---|
| Very high dev buy | The dev can dump a big share at once. |
| Fresh wallets funded by the same address | A classic sign of a group hiding behind several wallets. |
| A few wallets hold most of it | Two or three sells are enough to crash it. |
| Name copied from a hit coin | Copies are often bait. |
| Dev who rugged other coins before | Ruggers do it again with new coins. |
Settings that limit the damage
No tool catches every rug. What really protects you is rules applied on every trade. With Scope:
- Sell when the dev sells: you're out as soon as the creator sells, often before most of the drop.
- Stop loss: a max loss per position.
- Sell after X blocks: you don't stay long enough to be someone's exit.
- Dev buy filter: skip coins where the dev bought too much (or nothing).
- Banned words: skip copies and names you know are traps.
- Small amounts: a rug on a small position isn't a disaster.
Copying the ruggers?
Some traders flip it: they spot rugger groups and copy their buys on the next block, getting out very fast (sell after a few blocks). It's a risky strategy that needs a very tight exit. Scope's « fresh wallet » filter is made precisely to follow these groups' throwaway wallets.
FAQ
Can you detect a rug pull 100%?
No. Signs help, but ruggers adapt. Only automatic exits truly protect your capital.
Is a rug pull checker enough?
A checker gives a snapshot of the coin at one moment. It doesn't always see linked wallets, and it doesn't get you out when the selling starts.
What's a rugger?
A wallet (or group of wallets) that creates or buys coins to dump them on the next buyers. See the glossary.
