Crypto scams follow predictable patterns. The projects look identical to legitimate ones — a website, a whitepaper, social media activity, influencer promotion. The difference is in the smart contract code and the on-chain data, which most investors never look at. That is exactly what scammers rely on.
This guide explains the most common crypto scam types, how to read on-chain warning signs, and how to check any token's safety for free before you invest a single penny.
The Most Common Crypto Scam Types
- Honeypot — the contract lets you buy but blocks you from selling. Price goes up, you try to sell, transaction fails. The deployer exits and takes your money.
- Rug pull — developer holds a large portion of supply or controls the liquidity pool, then sells everything at once, crashing the price to zero.
- Mint function abuse — the contract has an unrestricted mint function that lets the owner print unlimited tokens, diluting your holdings to worthlessness.
- Hidden buy/sell tax — the contract charges 90–99% in fees on sells, making it practically impossible to exit.
- Fake liquidity — liquidity is not locked, so the developer can withdraw it from the pool at any time.
On-Chain Red Flags to Check
- Contract verified? — if the contract source code is not verified on Etherscan/BscScan, there is no way to read what it does
- Ownership concentration — one wallet holding 20%+ of supply is a major rug pull risk
- Locked liquidity? — liquidity should be locked for at least 6–12 months via a trusted locker
- Sell tax — any sell tax above 10% is a red flag; anything above 25% is almost always a scam
- Contract renounced? — renounced ownership means the developer cannot modify the contract post-launch
- Transaction history — check if there are organic buyers and sellers or just the deployer wallet moving tokens around
Step-by-Step: Check a Token's Safety Free
Go to webtoolsz.com/ai-crypto-scam-detector. No account required.
Find the contract address on the project's official website or a block explorer. Never use addresses from Telegram or Discord — those are often fake.
The tool checks on-chain data and flags honeypot risk, sell tax, ownership concentration, and liquidity lock status.
If any major red flags appear, treat the project as high risk. A clean scan does not guarantee safety — use it as one of several checks, not the only one.

Open Crypto Scam DetectorFrequently Asked Questions
What is a honeypot crypto token?
A honeypot is a token smart contract designed so that you can buy it but cannot sell it. The contract code allows incoming purchases but blocks or reverts any sell transaction. Buyers watch the price rise, try to sell, and discover they are stuck. The deployer then sells their own holdings and exits with everyone else's money.
What is a rug pull?
A rug pull happens when the developer or a large wallet holder sells a massive quantity of tokens all at once, crashing the price to near zero. They "pull the rug" from under investors. Warning signs include concentrated token ownership (one wallet holding 20%+ of supply) and unlocked liquidity.
Can I trust a token just because it is on a major DEX like Uniswap?
No. Anyone can list a token on a decentralized exchange without any vetting or approval. The presence on Uniswap, PancakeSwap, or any DEX means nothing about the token's legitimacy. Always check the contract and ownership data before investing.
What does "renounced contract" mean?
When a developer renounces ownership of a smart contract, they permanently give up the ability to modify it. This is generally a positive sign — it means they cannot add a sell block, change fees, or drain the liquidity pool after the fact. However, renouncement alone is not sufficient — a rug can still happen before renouncement.
