Honeypot Tokens: Why You Can Buy but Can't Sell

A honeypot token lets you buy but blocks or taxes away your sale. See how the trap looks, the checks to run before buying, and what to do if you’re stuck.

What is a honeypot token?

A honeypot token is a crypto token whose smart contract accepts your purchase but stops you from selling. The trap sits in the token’s own code, which decides whether any transfer succeeds. A 2024 academic study of contract-based scams (CRPWarner) described this category as “a mechanism to restrict users from selling tokens.”

Scam tokens of all kinds are common on open exchanges. A 2021 study of one large decentralized exchange found more than 10,000 scam tokens, roughly half of the tokens listed there at the time, and estimated that scammers made at least $16 million from 39,762 potential victims.

Honeypots are different from tokens that are merely hard to sell. An illiquid token has too few buyers, so your sale moves the price a lot (see crypto liquidity risk). A honeypot may have a busy chart and a funded pool, yet the contract itself refuses your sale or confiscates most of it.

What a honeypot looks like from the outside

The design is built to look like a winner. Because only buys execute, the price climbs in a smooth staircase, the holder count rises and group chats fill with screenshots of paper gains. Here is how that compares with an ordinary token:

When you try to sell a honeypot, you typically see one of three outcomes: your wallet warns that the transaction will fail, the transaction is sent and reverts, or it succeeds but delivers a tiny fraction of the value on screen. The first outcome costs nothing. The other two cost you gas.

The math of a sell-tax honeypot

Some honeypots let sales go through but let the owner raise the “sell tax” after buyers arrive. Your proceeds then follow a simple formula.

Example: Suppose you bought 500,000 Token X at a hypothetical $0.002 each, spending $1,000. The chart now shows $0.004, so your wallet displays $2,000. The owner has set the sell tax to 99%, and the network fee is a hypothetical $3.

Ignoring price impact, here is what the same position returns at different tax levels:

The fully blocked version is worse in a quieter way. Ethereum’s own documentation explains that when a transaction fails during execution, the gas it used is still consumed. Three failed sell attempts at a hypothetical $3 each add $9 to the loss without moving a single token. Our guide on why a failed transaction still costs gas explains the mechanics.

How to check for honeypot signs before you buy

1. Look for real sells

Open the token’s trade history on a block explorer and filter for sales into the pool. You want to see many different, ordinary wallets selling successfully. Hundreds of buys and almost no sells should end the decision.

2. Read what the owner can change

In the verified contract, look for owner-only functions that set fees, add wallets to a block list or allow list, cap transaction sizes, or turn trading on and off. If the source code isn’t verified, you can’t check any of this, which is itself a red flag.

3. Treat scanner results as a floor, not a pass

Token scanners simulate a buy and a sell. A clean result only means the sell worked in that simulation at that moment. An owner who can raise fees or block addresses can change the outcome after you buy.

4. Don’t lean on a tiny test sale

A small sale that succeeds proves little. Some contracts cap sell sizes, and settings can change after you add more money.

5. Ignore tokens that simply appear in your wallet

Unrequested tokens, often with a website in the name, are a common lure toward phishing pages. The patterns overlap with fake crypto airdrops and claim sites.

Common mistakes that keep people trapped

• Reading a smooth chart as strength. In a honeypot, the missing red candles are the tell, not a sign of loyal holders.
• Following instructions to set very high slippage. Promoters sometimes tell buyers to raise slippage tolerance “because of the tax.” A wide tolerance is exactly what lets a confiscatory sell tax take its cut without the trade failing.
• Trusting a rising holder count. In a honeypot, holders accumulate because nobody can leave.
• Accepting a feature story. Labels like “anti-bot protection” or “selling opens after launch” are common ways to present a sell restriction as a benefit.

What to do if you’re stuck in a honeypot

1. Stop retrying the sale. Each failed attempt burns gas and changes nothing.
2. Never pay to unlock. Anyone offering to whitelist or release your tokens for a fee, or asking for your recovery phrase, is running a second scam. Never share your recovery phrase with anyone.
3. Don’t buy more. Claims that you must hold a minimum balance or pay a “tax” before selling are part of the trap.
4. Clean up permissions. If you connected your wallet to the token’s website, review and revoke token approvals you granted there.
5. Save evidence. Note the contract address, the deployer’s address, your transaction hashes and screenshots of the channels that promoted the token.
6. Report it. In the US, report to the FTC at ReportFraud.ftc.gov and the FBI at ic3.gov; elsewhere, use your national fraud reporting service or local police. Our step-by-step guide on how to report a crypto scam covers the UK, EU and beyond.

If the loss affects your taxes, rules vary by country; check with a qualified professional.

The bottom line

A honeypot token turns a rising chart into bait: the buys are real, but the exit is controlled by someone else. Before you buy any new token, confirm that ordinary wallets can sell and that no owner can change the rules later. For the red flags that apply across every scam type, see how to spot a crypto scam.
