Rug Pull: Definition, Types And Prevention Strategies Of Cryptocurrency Scams
Introduction
In the rapid development of cryptocurrency and decentralized finance (DeFi), investors are constantly seeking high-return opportunities. However, this pursuit is often accompanied by significant risks, among which “Rug Pull” has become one of the most notorious scams. This report will explore the definition, classification, and avoidance methods of Rug Pull in depth, and analyze its impact through cases and data, aiming to provide comprehensive guidance for investors.
Rug Pull: The “Black Hole Trap” in the Cryptocurrency World
The term Rug Pull, derived from the metaphor of “pulling a rug,” is an act in which a developer suddenly abandons a project after raising funds and disappears with the funds, leaving investors holding worthless tokens.
This scam often occurs in the decentralized finance (DeFi) ecosystem, especially on decentralized exchanges (DEX). Scammers create a token and list it on a DEX, then pair it with a mainstream cryptocurrency such as Ethereum. Since DEX allows users to list tokens for free and without audits, and since creating tokens on open source blockchain protocols is easy and free, this provides favorable conditions for criminals.
According to Chainalysis data, the losses caused by cryptocurrency crimes in 2024 are estimated to be as high as $51 billion, of which Rug Pull scams account for 33.2% of the total losses, compared to only 1% in 2020, highlighting the dominance and growing threat of Rug Pull in cryptocurrency scams.

Avoiding Rug Pull requires investors to remain highly vigilant. The following are detailed suggestions:
Investigate the team background: Ensure that the team’s information is transparent, check its past projects and credibility. Anonymous teams are often dangerous signals.
Check smart contract audits: Confirm whether the project has a third-party audit, such as Certik, and review the audit report to find potential vulnerabilities. For example, Aptos is rated AAA, indicating high security.
Verify liquidity lock: Use tools such as Unicrypt or RugDoc to confirm whether liquidity has been locked for at least 6 months to prevent developers from withdrawing at any time.
Be wary of promises of high returns: 10% returns per day are usually scams and should be viewed with suspicion.
Monitor fund flows: Track money in and out through blockchain browsers such as Etherscan or Solscan and watch for unusual activity.
Engage in community interactions: An active and engaged community may indicate a legitimate project, but beware of artificially created fake engagement.
Start with small investments: Invest only what you can afford to lose and diversify your investments to avoid “all-in” risk.
Combined, these measures can significantly reduce the risk of Rug Pulls, but you still need to keep an eye on them.
