How the Rug Pull Checker works
The CleaRank Crypto Rug Checker is a token safety scanner that reads directly from the blockchain. Enter a token address or name, pick the chain, and get an on-chain security audit covering liquidity, holder distribution, contract flags, and activity, flagged in seconds.
What is a rug pull?
A rug pull is a crypto scam where a token’s creators drain the value out of it, typically by removing the liquidity that lets holders sell, minting unlimited new supply, or dumping a concentrated stash of tokens on the market. The warning signs live on-chain, in the token’s contract and holder data, which is exactly where the Rug Checker looks.
What the Rug Checker examines
- Liquidity. Whether the token has real, locked liquidity. Unlocked liquidity means the people who provided it can pull it at any time, which is the classic rug mechanism.
- Holder concentration. How the supply is distributed. If a few wallets hold most of the tokens, a single seller can collapse the price.
- Contract flags. Properties of the token contract itself, such as mint authority (can the creators print more tokens?) and whether the contract is verified.
- On-chain activity. What is actually happening with the token on-chain, which helps separate living projects from abandoned or manipulated ones.
The checks read direct on-chain data, so results reflect the token’s actual current state on the blockchain.
Run a token safety audit
- Enter the token. Paste the token’s contract address (the most reliable option) or search by name, for example WBTC.
- Pick the blockchain. Select the chain the token lives on, such as Ethereum, in the Blockchain field.
- Analyze. Click Analyze Token and review the flagged results of the safety audit.
Reading the results
Treat every flag as a reason to slow down. A single red flag, such as unlocked liquidity or an active mint authority, can be enough to walk away from a small-cap token, because it means the structural conditions for a rug exist regardless of the team’s stated intentions. A clean scan is a good sign, but it is not a guarantee; it means the common on-chain rug mechanisms are not present right now.

Which blockchains are supported?
Pick the chain the token lives on from the Blockchain selector, for example Ethereum. The audit then reads that chain’s data directly.
Does a clean scan mean a token is safe to buy?
No. A clean scan means the common on-chain rug mechanisms, like unlocked liquidity or an active mint authority, are not present at scan time. It says nothing about the project’s merits, price prospects, or off-chain risks.
What is a liquidity lock?
A liquidity lock is a mechanism that prevents a token’s liquidity providers from withdrawing the pooled funds for a set period. Locked liquidity means holders can keep selling; unlocked liquidity can be pulled at any moment, which is how most rug pulls work.
