What is a honeypot in crypto and how to spot one before you buy

Updated October 1, 2026 · 5 min read

What a honeypot is

The word comes from “honey pot”: a trap. In crypto, a honeypot is a token whose contract lets you buy but stops you from selling (or only lets whoever created the token sell). You see the price rising and your balance growing, but when you try to get out, the transaction fails or returns almost nothing.

That is what makes it so dangerous: on the chart there are no sells to give it away, only buys. Everything looks like a token taking off.

How the trap works

There are several technical ways to do it, and it helps to know them because each one leaves different clues:

• Sell blocking: the contract checks who is transferring and rejects the sale from everyone except an authorized list.
• Abusive sell tax: it lets you sell, but with a “tax” of 90% or more, so you recover almost nothing.
• Blacklist: the creator can block your wallet after you bought.
• Admin permissions over your funds (for example, on Solana, the authority to freeze token accounts): it is not a classic honeypot, but in practice the effect is similar if it is used against you.

Signs to be suspicious

• In the transaction history (DexScreener, for example) there are lots of buys and almost no sells.
• The token is very new and yet the price rises with no dips.
• The contract is not verified or cannot be read (on Ethereum-type or BNB Chain networks).
• Buy or sell taxes are high or changeable by the creator.
• The creator keeps active authorities over the token (create more, freeze accounts, block).

How to check it, step by step

1. Always start from the contract (CA), not the name. Clones with the same ticker exist. Copy the contract from a trusted source.
2. Use a checker that simulates the sale. On Ethereum-type and BNB Chain networks there are free tools that simulate a buy and a sell and show you the real taxes. On Solana, RugCheck checks whether the authorities are still active.
3. Look at the real sells. Open the token on DexScreener and see whether people have already sold and received their funds. If nobody sells, be wary.
4. Check who controls the contract: if the creator can change taxes, block wallets or freeze accounts, the risk is high.
5. If you still want to try, do it with an amount you are willing to lose entirely and confirm you can sell a small part before increasing. Even so, a small test guarantees nothing: some contracts change later.

What does not protect you

A token can pass every filter today and change tomorrow if the creator keeps permissions over the contract. And tools can fail with new or uncommon contracts. The best defense is to combine several signals and not to enter with money you cannot afford to lose.

Educational content, not financial advice. Memecoins are high-risk assets and you can lose everything you invest. No review guarantees that a token is safe.
