They will create a token and attract investors to buy in, while the investors have distributed certain amounts of capital, the creators will withdraw capital from the liquidity pool which makes the token price approximately zero. Generally, there are 3 types of rug pull:

• Stealing liquidity. In this type of rug pull, the scammers will create a liquidity pool with their token and pair it with top cryptocurrencies such as ETH or BNB. They will provide a large number of tokens to the pool and attract people to swift the tokens with their ETH or BNB, which will be locked up in the liquidity pool for a period of time. The more investors swift the token, the price of the token increase, which results in more ETH or BNB added to the pool. At last, the creator will "pull" all the ETH or BNB from the liquidity pool, leaving worthless tokens to the investors.

• Manipulate with technical. The developer can write a few lines of code to make the investors unable to sell or spend the tokens. How can it happen? Because the developers can modify the ERC20 tokens' "approve" function that the buyers cannot sell or spend the tokens except the developers. So when the price of the token goes up, people try to sell them to earn a profit, they realized it is unable to sell. Then the developers can sell all the tokens and run away.
• Developers drain out shares. A lot of projects' teams claim their projects are worth to invest. However, some of the projects mean nothing but only aims to get investors money and run away. This kind of developer creates a project with a high-value proposition. They make a wonderful roadmap and promise the token features or platform will be released soon. In fact, there is nothing behind the project and the token is worthless. They will keep a huge part of these tokens for themselves. When investors believe in the projects' potential and buy-in, the price goes up. The developers will sell out their shares(do it at once or in a period of time). At last, the investors just hold worthless tokens.
