Rug Pulls
A rug pull is when a token's creators drain or abandon liquidity so the price collapses. Warning signs cluster: concentrated supply, unlocked liquidity, risky authorities, and fake hype.
Quick answer
A rug pull crashes a token when insiders remove liquidity or dump supply. It is rarely one signal: concentrated holders, unlocked liquidity, dangerous token authorities, unverifiable claims, and coordinated hype tend to appear together.
What it means
A hard rug removes or drains liquidity suddenly. A slow rug is a gradual insider sell-off. Both leave later buyers holding tokens they cannot sell at a fair price.
Why it matters
Learning to weigh several warning signs together protects you better than reacting to any one metric. The exercise below asks you to review a fictional token and identify the risks.
What happens if you ignore this
A rug pull is not a bad trade you can recover from — it is a total loss. When the creator pulls liquidity, there is no one left to sell to at any price, and the chain won't reverse it. The whole defense is spotting the warning signs before you buy, because there is no after.
Common mistakes
Relying on a single 'green flag' (like a nice website) while ignoring unlocked liquidity or a wallet that controls most of the supply.
Story
Elena finds a token with a slick website, a busy chat, and a chart that's straight up. Everyone says it's the next big thing, so she buys.
She expects to ride the momentum for a quick multiple.
The liquidity was never locked and one wallet held most of the supply. Overnight the creator pulls the liquidity — the price goes to near zero and her sell button does nothing.
A polished website and loud hype are marketing, not safety. On-chain facts — locked liquidity, holder spread, revoked authorities — are what actually protect you.
Beginner tips
- Hype and a nice website prove nothing — check liquidity locks, holders, and authorities.
- If liquidity isn't locked or burned, the creator can remove it at any time.
- No single green flag outweighs several red ones. Weigh the signals together.
- When something feels too good and too urgent, that's the feeling scammers engineer.
Common mistakes
- Trusting hype and social proof over on-chain facts.
- Assuming a single safe signal outweighs several risky ones.
