Types of Crypto Scams We Detect
Every token analysis screens for these common crypto scam patterns across 31 chains.
Honeypot Tokens
Malicious contracts that let you buy but block selling. Your funds get permanently trapped the moment you purchase.
Rug Pulls
Developers yank all liquidity from the DEX pool, leaving the token worthless overnight. We verify whether liquidity is locked.
Wash Trading
Bots trade the same token back and forth to fake volume and lure in buyers. We flag suspicious volume-to-liquidity ratios.
Clone Farms
Scammers deploy dozens of identical tokens with the same name and logo as a legitimate project to confuse and trap buyers.
Drainer Contracts
Tokens or NFTs that, once approved, drain your wallet of all assets through hidden transfer-on-approval logic.
Phishing Tokens
Airdropped tokens with fake claim links in their metadata that lead to sites designed to steal your seed phrase or signatures.

Frequently Asked Questions
What is a crypto scam detector?
A crypto scam detector is a tool that analyses a token's smart contract, liquidity, holders, and on-chain behaviour to flag malicious patterns before you trade. Guava's crypto scam detector runs 30+ security checks across 31 chains in under 2 seconds.
Is the crypto scam detector free?
Yes — crypto scam detection is completely free on Guava. You can run a check on this page without signing up. Free accounts get 10 analyses per day. No credit card required.
Which blockchains are supported?
Guava checks EVM chains (Ethereum, BSC, Base, Arbitrum, Optimism, Polygon, Avalanche, Blast, zkSync, Linea, Scroll, Mantle, and more) using GoPlus Security, plus Solana via RugCheck — 31 chains in total.
What types of crypto scams does Guava detect?
We detect honeypot tokens, rug pulls, wash trading, clone farms, drainer contracts, and phishing tokens. Each analysis covers buy/sell taxes, mint authority, liquidity locks, holder concentration, proxy contracts, and hidden owner functions.
How accurate is the crypto scam check?
We run 30+ security checks per token using GoPlus and RugCheck — the same engines trusted by major crypto exchanges and DeFi protocols. Every token receives a risk score from 0 to 100 with colour-coded severity.
What does a 'Critical' risk score mean?
A Critical score (50+) means multiple severe red flags were detected — typically a honeypot, unlocked liquidity, or drainer logic. You should avoid trading this token entirely.
Can I check tokens on Solana?
Yes. Guava supports Solana token checks via RugCheck, which analyses mint authority, freeze authority, liquidity locks, and holder concentration. See our dedicated Solana Honeypot Checker page for more details.
What is a drainer contract?
A drainer contract is a token or NFT that, once you approve it in your wallet, silently transfers out all of your assets. Guava scans approval logic and metadata to flag drainer contracts before you interact.
How do I avoid crypto scams?
Always run a token through a scam detector before buying. Check for locked liquidity, verified source code, reasonable taxes, and a healthy holder distribution. Guava automates all of these checks in a single report.
Does Guava store my search history?
Your recent searches are stored locally in your browser for convenience. We do not share your search history with third parties.
