What is a Honeypot Token and How BarryGuard Detects Them
By BarryGuard Team · May 18, 2026 · 4 min read
A honeypot is the cruelest kind of token scam. It looks normal. People are buying it. The price is going up. You buy in. And then you discover you cannot sell. Your money is trapped, and the only person who can move funds is the person who created the token.
Honeypots are especially common on EVM chains — Ethereum, BNB Chain, and Base — because the smart contract language makes it easy to hide sell restrictions inside the code.
How a honeypot works
The token contract is written so that buying works normally for everyone, but selling is blocked for most wallets. The creator usually whitelists their own address so they are the only one who can sell. From the outside, it looks like a popular token with real trading activity — but all that activity is one-sided.
Some honeypots are simpler: the sell function just reverts for everyone except the owner. Others are more subtle — they allow selling but charge a 99% tax that goes straight to the creator. Either way, the result is the same: you put money in, and you cannot get it back.
Why honeypots happen
Honeypots are cheap and easy to create. There are even services that let anyone deploy a honeypot contract in minutes without writing any code. The creator launches the token, buys a small amount themselves, watches others pile in, and then drains the liquidity.
The scam works because most traders never read the contract code. They see a token with a chart going up, a Telegram group with thousands of members, and they assume it is safe. By the time they try to sell, it is too late.
How BarryGuard detects honeypots
BarryGuard runs several checks that catch the most common honeypot patterns:
- Sell restriction check: We simulate whether a normal wallet can actually execute a sell transaction. If it fails, that is an immediate danger signal.
- Blacklist analysis: We check whether the contract can block specific addresses from trading. If the owner has that power and the contract is not renounced, it is a risk.
- Hidden tax detection: We look for code paths where the buy and sell taxes can differ dramatically. If the maximum possible sell tax is near 100%, the token is flagged.
- Whitelist pattern detection: We scan for patterns where certain addresses get special privileges (like zero tax or unrestricted selling) while others are locked out.
None of these checks require you to understand code. BarryGuard runs them automatically and reports the results as part of the overall score.
What to do if you suspect a honeypot
If BarryGuard flags a token as a honeypot risk, the safest move is not to buy it at all. If you already hold it:
- Try a small test sell: Attempt to sell a tiny amount. If the transaction fails, the token is almost certainly a honeypot.
- Check the contract directly: Look at the verified source code on a block explorer. Search for terms like "blacklist," "whitelist," or "onlyOwner" near sell functions.
- Do not add more: Some people try to "average down" on a honeypot, thinking the price will recover. It will not. The only seller is the scammer.
Honeypots are one of the fastest-growing scams on EVM chains. BarryGuard exists so you do not have to become a smart contract auditor to stay safe. Paste the address, check the score, and move on if it looks bad.
