Free Rug Pull Checker — Detect Crypto Scams Before You Invest
Paste any contract address to instantly scan for honeypots, hidden mints, ownership exploits, and 20+ other red flags across Ethereum, BSC, Polygon, and more.
How It Works
Three steps to check if a token is safe — no wallet connection required.
Paste the Contract Address
Copy the token's contract address from your wallet, DEX, or block explorer. Paste it into the SkyEye search bar. We support Ethereum, BSC, Polygon, Arbitrum, Base, and 10+ other chains.
AI-Powered Analysis
Our 7-layer AI engine scans the smart contract source code, on-chain behavior, ownership structure, liquidity status, and holder distribution in seconds. No manual review needed.
Get Your Safety Score
Receive a 0–100 security score with a letter grade (A+ to F), plus a detailed breakdown of every risk factor found. Critical findings include exploit evidence from our sandbox environment.
What We Detect
Our scanner checks for 20+ rug pull indicators. Here are the most critical ones.
Hidden Mint Functions
Detects functions that allow the owner to mint unlimited tokens, diluting holders and enabling dump-and-run schemes.
Liquidity Withdrawal Risk
Checks whether liquidity is locked, the lock duration, and whether the owner can remove LP tokens to drain the pool.
Ownership Concentration
Flags contracts where a single wallet or a small group controls a dangerous percentage of the total supply.
Honeypot Mechanisms
Identifies sell-blocking code, dynamic tax manipulation, blacklist functions, and other patterns that prevent holders from selling.
Proxy & Upgrade Risks
Detects upgradeable proxy patterns where the owner can silently change contract logic after deployment.
Suspicious Fee Structures
Analyzes buy/sell taxes, transfer fees, and hidden fee functions that funnel value to the deployer's wallet.
Frequently Asked Questions
What is a rug pull in crypto?
A rug pull is a type of exit scam where developers create a token, attract investment through marketing and liquidity, then withdraw funds or exploit contract backdoors to steal investors' money. Common tactics include removing liquidity, using hidden mint functions, or deploying honeypot contracts that block selling.
Is this rug pull checker really free?
Yes. The SkyEye public scanner provides free security scores and risk assessments for any contract address. You can check unlimited tokens without creating an account or connecting a wallet. For detailed audit reports with full exploit evidence, FinGuard offers professional audit services.
Which blockchains does the checker support?
We support Ethereum, BSC (BNB Chain), Polygon, Arbitrum, Base, Optimism, Avalanche, Fantom, Cronos, and other EVM-compatible chains. New chains are added regularly as our coverage expands.
How accurate is the rug pull detection?
Our AI engine combines static analysis, on-chain behavioral analysis, and sandbox exploit verification. While no tool can guarantee 100% detection of all scam variants, our multi-layer approach catches the vast majority of known rug pull patterns. Always combine tool results with your own research.
What should I do if the checker flags a project?
A low score or critical red flags should be treated as strong warning signs. Review the specific risks identified, check whether the team has addressed them, look for independent audits, and consider the project's overall transparency. When in doubt, do not invest — protecting your capital is more important than FOMO.
