How to Spot a Rug Pull in Crypto (2026 Checklist)
Most rug pulls follow the same handful of patterns. If you can read a chart and a block explorer for five minutes, you can filter out 90% of them before you ever hit buy. Here's the checklist.
What is a rug pull?
A rug pull is when the people behind a token drain its liquidity or dump their bag on holders, tanking the price to near zero. It can be a "hard rug" (the deployer pulls LP or mints infinite supply) or a "soft rug" (team sells everything and abandons the project). Both leave holders with a chart that looks like a cliff.
The 8-point pre-buy checklist
1. Is the LP burned or locked?
If the deployer still holds the LP tokens, they can withdraw all the liquidity in one transaction. On a launchpad like Memez.wtf, LP is auto-burned at graduation — check the block explorer to confirm.
2. What does the top-10 holder concentration look like?
If one wallet holds more than ~5% (outside the LP), that wallet can crash the chart alone. Bonding-curve launches often show high concentration early — wait for it to spread out.
3. Can the contract mint more tokens?
Look for an unrenounced mint authority (Solana) or a mint() function callable by the deployer (EVM). Both let the team print supply and dump it.
4. Are transfers freezable or blacklistable?
Some contracts let the deployer block wallets from selling. If you see freeze_authority set or a blacklist mapping in the code, walk.
5. Is there a hidden sell tax?
A 5% buy tax and a 50% sell tax means you're the exit liquidity. Simulate a sell on a small amount before committing.
6. Does the team have unlocks coming?
Cliffs and unlocks are on-chain. Check for large tranches unlocking soon — that's when soft rugs usually happen.
7. Is the community real?
Telegram with 20k members and three messages an hour is bought. Real communities argue, meme, and post charts unprompted.
8. Has the deployer done this before?
Paste the deployer address into a block explorer. If they've launched five tokens that all went to zero, this is #6.
Red flags to walk from immediately
- Unrenounced mint authority on Solana or an owner() that can call mint() on EVM.
- LP tokens held by an EOA, not a burn address or lock contract.
- One wallet holds > 10% outside the LP.
- Contract source not verified and no audit.
- Sell tax higher than buy tax.
- Team demands DMs before you can "get in".
How Memez.wtf reduces rug risk
Fixed, audited contracts
Every Memez token uses the same audited contract per chain. There is no per-token Solidity for a team to sneak a mint() into.
LP burned at graduation
When the bonding curve fills, liquidity migrates to a DEX and the LP tokens are burned. Nobody — including the team — can pull it.
No team allocation
100% of supply is on the bonding curve. There is no hidden team wallet with a cliff to unlock.
Transparent holders
Every token page shows top holders in real time. Concentration risk is one glance away, not buried in a scanner.
What to do if you got rugged
Sell the residual bag if the pool still has anything, log the deployer address, and report the token. Don't average down. Don't wait for a "recovery" — rugged tokens almost never come back. Treat it as a tuition payment for the checklist above.
