How to Spot a Rug Pull in Crypto
Common types of rug pull
- Liquidity pull: the creator withdraws the pool, so nobody can sell.
- Supply dump: a hidden group sells a large holding into buyers.
- Minting: new tokens are created and sold, collapsing the price.
- Honeypot: the token lets you buy but blocks selling.
On-chain checks
- Mint authority: if active, the owner can create more tokens. Revoked is better.
- Freeze authority: if active, wallets could be frozen. Revoked is better.
- Holders: see holder distribution for concentration.
- Liquidity: find out who controls it and whether it is locked or burned.
- Token program extensions: check for transfer fees or other controls, as in token standards.
QNT has its mint, freeze and metadata update authorities revoked, as read on-chain on 2026-10-08. That removes some rug mechanisms, but not all. Holders can still sell, and the price can still fall to near zero.
Off-chain warning signs
- Promises of guaranteed returns or urgent deadlines.
- Anonymous accounts pushing you to buy through direct messages.
- Copycat tokens using a real name with a different address.

Be honest about uncertainty. Some rugs look perfectly normal until the moment they happen, and some safe-looking checks can be bypassed. The goal is not certainty but fewer easy mistakes. Size your positions so that a total loss would not hurt you, and walk away from anything that pressures you to act quickly.
A worked example of the numbers behind a liquidity pull
These figures are invented. A pool holds 100 SOL and 100,000,000 tokens. The creator holds 100 percent of the liquidity tokens. If they withdraw, the pool is empty, and every other holder is left with tokens that have nothing to trade against. Now imagine liquidity is burned or locked: the creator cannot withdraw, but they could still sell their own 15 percent holding. Selling 15,000,000 tokens (s = 15 percent of the token side) into that pool would push the price down by 1 / (1.15 squared), about 24 percent, and the seller would receive 100 SOL times 0.15 / 1.15, about 13 SOL. That is the dump scenario, and it is why holder concentration matters even when liquidity is secure. See Holder Concentration and Whale Risk and the price impact calculator.
Which checks catch which attack
| Attack | What helps | What it does not stop |
|---|---|---|
| Minting more tokens | Revoked mint authority | Sales by existing large holders |
| Freezing your wallet | Revoked freeze authority | A permanent delegate extension, if present |
| Pulling liquidity | Burned or locked liquidity tokens | A lock that expires |
| Honeypot or hidden transfer rules | Reading extensions and testing with a tiny sell | Rules added through other mechanisms |
| Dumping a big holding | Spread-out holders | Holders who control many wallets |
Solana's Token-2022 extensions such as a permanent delegate, a transfer fee or a transfer hook can give an account power over holders' tokens or change transfers. See Token-2022 Extensions Explained for Holders.
Common mistakes
- Treating "authorities revoked" as "cannot lose money".
- Believing a famous name in a thread. Impostors copy names and logos.
- Skipping the test sell on a new token.
- Paying "recovery agents", which are usually a second scam. See Phishing, Fake Airdrops and Fake Support.

Frequently asked questions
What does rug pull mean?
It means the people behind a token pull value out, such as by draining liquidity or dumping supply, leaving other holders with tokens they cannot sell for value.
Can I tell for sure if a token is a rug?
No. Checks reduce risk but cannot remove it. Even a token with revoked authorities can lose nearly all its value.
Do revoked authorities mean QNT cannot be rugged?
They remove the ability to mint more, freeze wallets or change metadata, but they do not guarantee price or liquidity.
What should I do if I think I was rugged?
Stop interacting with the token, never pay anyone who offers recovery, and keep records. Be wary of recovery scams.
Is every price crash a rug pull?
No. Markets can fall without any deception, which is a risk of memecoins. A rug pull involves insiders removing value or exploiting hidden powers.
What is a honeypot?
A token that lets you buy but blocks or heavily taxes selling, through hidden code or settings.
Are rug pulls illegal?
Often they involve fraud, but enforcement is hard across borders. A 2025 SEC staff statement on meme coins noted that fraud can still be pursued. Do not rely on legal recovery.
Can I test a token safely?
A very small buy and sell can reveal obvious blocks, but it cannot prove the token is safe later.
