Honeypot Tokens — The Trap You Can Buy but Can't Sell

What is a honeypot?

A honeypot is a token you can buy but cannot sell. Like a honey jar your hand goes into but can't come back out of, the buy path is left open while only the sell path is blocked by the contract code. As victims pile up, the chart keeps rising — because no one can sell, sell volume is zero. That "only-goes-up chart" is exactly the bait.

Common tricks that block selling

• Sell-blocking logic — a condition such as "cannot sell unless you are the developer wallet" is embedded in the contract's transfer function. On the surface, the function names look ordinary.
• Extreme taxes — a tax of tens of percent is applied to selling only, so the more you sell the more you lose. If the power to raise the rate later (a mutable tax) remains, it can turn into a trap at any time even if it looks normal now.
• Blacklist — a feature that blocks specific wallets from trading. Early on no one is blocked; once supply has accumulated, wallets that try to sell get blocked.
• Trading pause — a switch that lets the owner halt all trading. It is planted under the banner of an "emergency stop," but can be used to lock the exit.

Why it's easy to fall for

A honeypot looks like a normal token until you actually try to sell. The chart, the holder count, and the (buy) volume are all real. Even a small "test buy" goes through, so you feel reassured — but the problem is on the sell side, and you don't find that out until you've been caught.

How to check before you get scammed

Fortunately, whether a token can be sold can be checked without actually buying it — simulating a buy and a sell reveals whether the code blocks selling. CheckCrypto's honeypot check focuses on this one question ("can I sell?") and tells you for free whether there is sell-blocking, extreme taxes, or blocking mechanisms.

A caution: "unconfirmed" is not "safe." Not being able to confirm because there is no data is different from confirming that something is normal. CheckCrypto always distinguishes the two — it is a principle of our evaluation method.

What to remember

• A brand-new token whose chart only goes up can be a warning, not an attraction — if no one can sell, the chart can't go down.
• The fact that buying works is not evidence that selling works.
• A 30-second honeypot check before trading filters out one of the worst traps. Check the full set of risk signals with a scam check.
