Memecoin Rug Check: Score Any Token's Rug Pull Risk in Seconds
Before you ape, run the address through a rug check. DeFade inspects the token's contract, liquidity, holders and — most importantly — the behavior of its dev and insider wallets, then gives you a single rug risk score. Free, no wallet connection, on Solana, Ethereum and Base.
Rug check a token now →What the rug check inspects
| Signal | Question it answers | Weight |
|---|---|---|
| Dev wallet history | Has the creator sold, transferred or wallet-hopped supply? What happened to their previous launches? | High |
| Launch bundles | Was supply bought by coordinated wallets in the launch block? | High |
| Insider clusters | Are the "top holders" actually one funding wallet fanned out? | High |
| Holder concentration | Can a handful of wallets nuke the chart? | Medium |
| Liquidity health | Is liquidity locked/burned, and is it deep enough to exit? | Medium |
| Contract permissions | Mint authority, freeze authority, upgradability, taxes | Medium |
| Sniper activity | Who got in at block one and are they connected to the deployer? | Medium |
Why contract-only rug checkers miss modern rugs
On launchpads like pump.fun, every token ships from the same audited factory contract — mint revoked, no taxes, liquidity handled by the bonding curve. A contract-only rug check gives almost everything a green light. Yet most of these tokens still die within hours, because the rug isn't in the code: it's the deployer holding 40% through six "unrelated" wallets that all trace back to one funding source.
That's the layer DeFade was built for. Our rug database records confirmed rug pulls together with the wallet patterns that preceded them, and those patterns power the score you see. When the dev of a two-hour-old token shows "TRANSFERRED OUT" or the bundle detector finds 30 wallets buying in the launch block, you're looking at the same setup that preceded thousands of documented rugs.
How to run a rug check (30 seconds)
- Copy the token's mint/contract address from DexScreener, pump.fun or the project page.
- Paste it into the DeFade scanner — it auto-detects the chain.
- Read the rug risk score and open the modules that triggered it.
- Cross-check the Dev Wallet Tracker: Still Holding is neutral, Fully Exited on a fresh token is a warning, Transferred Out is a red alert.
- If bundles + insider clusters + concentrated holders line up together, walk away — the exit is pre-planned.

Frequently asked questions
- What is a rug check?
- An on-chain inspection that estimates how likely a token's creators are to pull liquidity or dump supply. It combines contract permissions, liquidity status, holder concentration and the behavior of dev and insider wallets.
- Can a rug check guarantee a token is safe?
- No. It quantifies known risk factors — a low score means the common rug patterns are absent, not that profit is likely. Treat every memecoin position as money you can lose.
- Does it work on pump.fun tokens?
- Yes — bundle sniping, disguised dev buys and insider clusters are checked from the very first block of a bonding-curve launch.
- Do I need to connect a wallet?
- No. Rug checks are read-only and free. A wallet is only needed if you use the built-in trading features.
