Rug Pull

A rug pull is a type of exit scam where cryptocurrency project developers or promoters abandon a project and steal investor funds, typically by removing liquidity from decentralized exchanges or blocking token transfers. Developers create hype around a new token or DeFi protocol, attracting investments and liquidity from retail investors, then abruptly drain the smart contract or wallet containing assets and disappear. The term originates from the metaphor of literally pulling a rug out from under someone. Rug pulls are particularly prevalent in early-stage tokens and unaudited DeFi projects where developer identities are anonymous and contract code contains hidden backdoors. Example: The Squid Game token (SQUID) in 2021 promised blockchain-based gaming returns but locked investors' tokens while developers withdrew $3.36 million in liquidity, preventing victims from selling and leaving them with worthless holdings. Why it matters for DeFi: Rug pulls represent one of the highest-risk vectors in DeFi, destroying millions in retail capital. Investors must conduct thorough audits, verify developer identities, check liquidity lock periods, and analyze contract code to distinguish legitimate protocols from potential scams before committing funds.
