In plain English
What Rug pull means
A rug pull usually happens in DeFi or new token launches. The project may look legitimate at first, with a website, social media presence, token, and trading activity. After enough funds enter the project, the operators exit in a way that leaves buyers with little or no value. The term is informal, but it is widely used in crypto fraud analysis.
Why it matters
Rug pulls are a major counterparty and fraud risk in token markets. They can involve smart-contract tricks, hidden admin privileges, misleading marketing, or simple abandonment. For users, the main risk is that apparent liquidity and activity do not prove that a project is credible or sustainable.
Example
A team launches a new token, promotes it heavily, and adds liquidity to a pool so trading starts. Once enough buyers enter, the team removes the liquidity or sells a large insider allocation, causing the price to collapse and trapping late buyers.
