How to Spot a Crypto Rug Pull Before You Buy
A rug pull is when a token's creators deliberately drain value and disappear — by pulling liquidity, dumping a hidden allocation, or coding the contract so buyers can never sell. Unlike a project that simply fails, a rug is designed to steal from the start. The good news: most leave detectable fingerprints.
1. Liquidity — is it locked? If the team can withdraw the trading liquidity at will, they can pull it the moment buyers pile in. Look for liquidity locked in a reputable locker for a meaningful period.
Key takeaways: Unlocked or removable liquidity is the biggest red flag. Mint functions and hidden owner privileges let teams print or freeze tokens. Concentrated holders can dump the entire float at once. If you can buy but can't sell, it's a honeypot.
