How Rug Pulls Occur
Developers create a cryptocurrency or DeFi project with enticing profit potential for investors. Once sufficient funds are deposited, they abruptly liquidate holdings and abandon the project. These scams often involve low-effort projects designed solely to defraud speculative investors, executed within days or months depending on the scheme's sophistication.
Types of Rug Pulls
1. Liquidity Theft
Developers establish a liquidity pool for their token using paired assets (e.g., ETH). As token value rises:
- Investors lock funds into the pool
- Malicious teams withdraw paired assets (e.g., ETH), leaving worthless tokens
- Example: Squid Game Token (SQUID) collapse in 2021
2. Disabling Sell Functions
Fraudulent code prevents investors from selling tokens while allowing developers to cash out:
- Investors can buy but not sell tokens
- Developers dump holdings at peak prices
- Often involves hidden malicious smart contract code
3. Developer Cash-Outs
Projects launch with inflated promises but:
- Developers allocate themselves large token portions
- Slowly or suddenly sell holdings after price inflation
- Leaves investors with valueless tokens
