What is a rug pull? How memecoin scams work on Solana

A rug pull is when the people behind a token take the money and leave everyone else holding something worthless. The name comes from the image of a rug being yanked out from under your feet. On Solana, where anyone can launch a token in minutes for a few dollars, rug pulls are common. Knowing how they work won't make you immune, but it will help you spot the most obvious traps.

The main types of rug pull

1. Liquidity pull

Most memecoins trade against a liquidity pool: a pot of the token paired with SOL or a stablecoin. Whoever created the pool holds LP tokens that let them withdraw it. If those LP tokens are not locked or burned, the creator can pull the liquidity at any moment. The price collapses, and there is nothing left to sell into.

2. Honeypot

A honeypot lets you buy but not sell. The contract or its configuration blocks or heavily taxes sells for everyone except the creator. The chart looks great because nobody can exit, right up until the creator sells their own bag.

3. Mint and freeze abuse

Solana tokens have two powerful settings. Mint authority lets the holder create new tokens out of thin air, diluting everyone else. Freeze authority lets the holder freeze any wallet's tokens so they can't be moved. If either is still active, the creator keeps a lever they can pull later.

4. Slow rug or dev dump

Not every rug is a single dramatic event. Often the developer, or a cluster of insider wallets, holds a large share of supply and sells it gradually into buying pressure. The token bleeds out over hours or days. There is no smoking gun, just a chart that keeps going down while insiders cash out.

Warning signs you can check on-chain

None of these require trusting anyone. They are all visible on the blockchain:

• Can you actually sell? A simulated sell transaction reveals most honeypots.
• Is liquidity locked or burned? If most of the LP is unlocked, the pool can disappear.
• Are mint and freeze authority revoked? Revoked means nobody can inflate supply or freeze wallets.
• How concentrated is ownership? If the top ten wallets hold a large share, a few people can crash the price. Exclude the liquidity pool itself when you read this number.
• Has the developer been selling? A creator who has already sold most of their tokens is telling you something.
• How old is the token and how deep is liquidity? Very new tokens with thin liquidity can move 50% on a single trade, in either direction.

How DYOR shows this

Every token page on DYOR has a rug check covering sellability, liquidity lock, mint and freeze authority, top-ten holder share and developer selling. Each item is marked pass, warning or not checked. That last label matters: if we don't have data for a check, we say so rather than showing a reassuring green tick. Missing data is not good news. You can see an example on any token linked from the live feed.

What a rug check can't tell you

A token can pass every automated check and still go to zero. Checks catch mechanical traps, not bad intentions or simple lack of interest. A team can lock liquidity and revoke authorities and still hold a huge bag they sell later through many wallets. Or the hype can simply fade. Most memecoins end up worth a small fraction of their peak even when nobody did anything dishonest.

So treat a passed check as the minimum, not a green light. Size every position as if it could go to zero, because it can. Be especially careful with tokens that are only minutes old, and with anything being pushed hard by accounts you can't verify.

The short version

A rug pull is the creator taking the exit and leaving you without one. Check that you can sell, that liquidity is locked, that mint and freeze are revoked and that supply isn't concentrated. Then remember that passing all of that still isn't a promise of anything. Only trade what you can afford to lose entirely.
