How a rug pull works
A memecoin trades against a pool, for example TOKEN/SOL. The pool is what lets buyers sell. A typical memecoin rug looks like this: a dev launches a coin, hype on X and Telegram pulls in buyers, and the price climbs. Then the dev either removes the pool's liquidity or sells a large supply that insiders held from the start. With no buyers left on the other side, the chart drops in one candle.
A third method sits in the token's code or permissions. If the dev keeps the mint authority, the dev can print new tokens and sell them. If the dev keeps the freeze authority, the token can become a honeypot that you can buy but not sell.
