Honeypot Checker for Crypto: Don't Buy Tokens You Can't Sell

Honeypots are one of the most common scams on DEXes. The token looks normal — it has liquidity, people are buying, the price is going up. But when you try to sell, the transaction fails. Your tokens are trapped. Your money is gone. The dev waits for enough victims, then removes liquidity with the buy-side tokens.

Checking for honeypots before buying is the single most important safety step for DEX traders.

How Honeypots Work

Honeypot contracts include hidden code that prevents selling. Common mechanisms include:

• Blacklist functions — The contract can blacklist addresses after they buy, blocking sells
• Maximum sell limits — Sells are limited to tiny amounts that make it impossible to exit meaningfully
• Hidden taxes — Sell tax is set to 99%, so you get almost nothing back
• Time locks — Selling is blocked for a period, giving the dev time to rug
• Whitelisted selling — Only the deployer's wallet can execute sells

How to Check for Honeypots

Contract Analysis

Read the contract source code if it's verified. Look for functions like setMaxSellAmount, blacklistAddress, or unusual transfer restrictions. If the contract isn't verified — that's already a red flag.

Test Sells

Buy a tiny amount (the minimum possible) and immediately try to sell it. If the sell transaction reverts or you receive far less than expected, it's a honeypot. Better to lose $2 testing than $200 learning the hard way.

On-Chain History

Check the token's transaction history on DexScout. If you see many buys but zero or very few sells, it's almost certainly a honeypot. Healthy tokens have balanced buy and sell activity.
