What is a rug pull?
A rug pull happens when the creators of a crypto token, or another party with special control over it, suddenly drain the project's value. They usually do this by pulling out the money backing the token, selling off their own holdings, or using code built into the token that stops other users from selling. Users are left holding a token that's worth little or nothing, while the people behind it disappear with the money.
Rug pulls are one of the most common scams tied to new tokens and meme coins, the kind that seem to appear overnight, spike in value, and then collapse within hours or minutes. These schemes rely on social media hype, thin trading activity, and fear of missing out (FOMO), the anxiety that pushes people to buy in fast so they don't miss a rally. Scammers count on that urgency to stop users from checking the token first.
How does a rug pull happen?
Every rug pull looks a little different, but most follow the same basic pattern.
A scammer creates a new token, often with a polished website, a fake team, and heavy social media promotion. They may promise high returns or early access to build excitement fast.
The scammer adds the token to a liquidity pool, a shared pot of crypto that lets users buy and sell it. This makes the token look tradable and legitimate.
As interest builds, the scammer promotes the token further through influencers, giveaways, or viral posts to draw in more users.
Once enough money has flowed into the pool, the scammer strikes. They may pull out the pool's funds, sell their own tokens in bulk, or trigger code that blocks other users from selling. The price collapses instantly.
The token's website and social accounts go dark, and the scammer disappears, often within minutes.
Types of rug pulls
Liquidity rug pulls
In this version, the scammer drains the entire liquidity pool once it's built up enough value.
The scammer creates a token and sets up a liquidity pool for it.
Setting up the pool gives the scammer liquidity pool (LP) tokens or an NFT. These represent ownership of the pool and are the key to the scam.
The scammer holds onto the LP tokens or NFT while users buy in and the pool grows.
Once the pool is large enough, the scammer withdraws everything and burns the LP tokens or NFT.
Users are left with an empty pool and tokens that can't be traded. The scammer often resurfaces under a new address to repeat the scheme.
Pump and dump schemes
Here, the scammer sets up an early advantage, then sells it off once the price rises.
When the scammer creates the token, they keep a large share of it in their own wallet or in other wallets they control.
They fund the liquidity pool and may lock or burn some LP tokens to appear trustworthy.
Once the price rises and enough money is in the pool, the scammer sells their holdings all at once. The price crashes, the pool is drained, and users are left holding a token that's now worth very little.
Hidden code tricks
Some scammers build the scam directly into the token's code. A hidden mint function lets a privileged wallet create new tokens secretly, so the scammer can flood the market at any time without holding tokens upfront. Elevated privileges give developer-controlled wallets unusual powers, like unlimited approvals or the ability to move or reduce other users' balances. High tax rates build in unfair fees on sales, trapping users and sending the proceeds to the scammer. Fake token locks make users believe the liquidity is secured when it isn't. Sell blockers use blacklists or restrictions that stop users from selling while the scammer exits. On some networks, if the scammer keeps control over minting or freezing tokens, they can lock user balances or create unlimited tokens to dump.
Wash trading: faking popularity
Wash trading is when a scammer buys and sells their own token to make it look more active and popular than it is. That fake activity can land the token on trending lists, which draws in real users through FOMO. A single scammer might trade a token between wallets they control, or run bots that execute large numbers of small trades to simulate demand. Coordinated groups of accounts trading with each other can create the same illusion, and in pools with little real liquidity, even small trades can move the price enough to look like genuine demand.
How to protect yourself
Before you buy any new token, do your own research. Watch for contracts that are unverified or hard to read, and check whether the project has been through a credible audit. Look closely at the liquidity pool. If it isn't locked, or holds very little value, that's a warning sign. Check how the token is distributed. If a few wallets hold most of the supply, or many wallets hold the exact same small amount, that can point to wash trading. Be cautious of anonymous teams with no track record and no audits, even if they claim partnerships with well-known companies. Watch for aggressive promotion, like promises of huge returns in a short time, especially from unverified social media accounts. If a price chart moves in a way that doesn't look natural, treat it as a signal that something may be off.
If a project looks too good to be true, especially one that's only been live for a few minutes, that's often exactly what it is. Checking the contract, the liquidity, the token distribution, and the marketing pattern before you buy can help you tell a real opportunity from a scam.
