Rug pulls are the most common DeFi exit scam. Learn to read the on-chain signals before the developer disappears with your funds.
A rug pull happens when a token’s developers deliberately drain the liquidity pool or dump their token allocation, crashing the price to zero and leaving buyers with worthless tokens. It is the most common form of exit scam in DeFi.
Rug pulls account for the majority of crypto losses in DeFi. Unlike honeypots, they can sometimes happen weeks or months after launch — after trust has been built.
A rug pull occurs when a development team creates a token, attracts investment, then suddenly removes all liquidity or dumps their holdings — leaving the community with tokens that cannot be sold for any meaningful value. The term comes from the phrase “pulling the rug out” from under investors.
These signals are visible on-chain before a rug pull happens. Check them before buying any new token:
Unlocked liquidity is the single biggest rug pull indicator. If LP tokens are not locked for at least 6 months, the developer can drain the pool in one transaction.
Not all rug pulls are instant. Understanding the difference helps you recognize them earlier:
DexScanr scans liquidity lock status, holder concentration, ownership, and deployer history automatically.
DexScanr performs automated on-chain analysis that covers every major rug pull vector. When you paste a token contract address, DexScanr checks:
DexScanr supports ETH, BNB Chain, Base, Polygon, and Arbitrum. Scan any token on any of these chains instantly.
