What Is a Honeypot Token? How to Check If You Can Sell
A honeypot token lets you buy but not sell. Learn how honeypot contracts work — blacklists, freeze authority, sell taxes — and how to detect one before you buy.
TRENCHSCORE RESEARCH··4 MIN READ
A honeypot token is a token you can buy but can't sell. The chart looks great — nothing but green candles — because nobody can sell. Every buyer adds to the pool, and only the people who wrote the contract can take money out.
It's one of the oldest scams in DeFi, and it still works because the trap is hidden in code most traders never read.
//How a honeypot works
Every token transfer runs through the token contract. A honeypot adds conditions to that transfer logic so that buys go through but sells fail, or sells technically succeed but lose almost everything to fees. The common mechanisms:
| Mechanism | What happens to you |
|---|---|
| Blacklist | Your wallet is added to a block list after you buy. Sells revert. |
| Whitelist-only selling | Only addresses the owner approved (usually their own) can sell. |
| Extreme or adjustable sell tax | The owner raises the sell tax to 90–100% after launch. Your sell "works" but you receive almost nothing. |
| Freeze authority (Solana) | The owner freezes your token account. You can't transfer or sell. |
| Max-sell or cooldown traps | Limits so small, or cooldowns so long, that you can never exit meaningful size. |
| Balance manipulation | Hidden functions let the owner change balances or take tokens back. |
On Solana there's a newer variant using Token-2022's permanent delegate extension, which lets a designated address move or burn tokens from any holder's account. In 2024, traders reported buys that were burned from their wallets seconds after the swap. See Token-2022 extension risks.
//Why the chart looks so good
Because sellers are blocked, a honeypot's chart shows almost nothing but buys. Volume climbs, the price only goes up, and buy/sell ratios look incredible. That's exactly what attracts the next buyer. A chart with no meaningful sells at all is a warning sign, not a bullish one — especially on a token that's more than a few minutes old. Our guide on buy/sell pressure covers what normal looks like.
//How to check for a honeypot
1. Run a sell simulation
Security services simulate buying and then selling the token against the live pool. If the sell reverts or returns a fraction of the expected amount, it's a honeypot or a near-honeypot. TrenchScore runs this simulation on every EVM token page as part of the contract audit.
2. Check for blacklist, whitelist and hidden-owner flags
Scanners read the contract for functions that let an owner block addresses, change balances, or keep control through a hidden owner. Any of these is a reason to stop unless there's a clear, legitimate reason (for example, a regulated stablecoin).
3. Look at the taxes — and whether they can change
A static 5% sell tax is a business decision. A tax the owner can raise at any time is a loaded gun. Read buy and sell taxes.
4. On Solana, check freeze authority
If the freeze authority hasn't been revoked, the creator can freeze any holder's account. Most legitimate memecoins revoke it at launch. See mint and freeze authority explained.
5. Look for real sellers
Open the transaction list. Are there sells from many different wallets — not just the deployer? If a token has hundreds of buyers and nobody but one address has ever sold, assume a trap.
//Can a token become a honeypot after launch?
Yes. If the owner keeps control of the contract — through an owner role, an upgradeable proxy or an adjustable tax — a token that passes a sell simulation today can be turned into a honeypot tomorrow. That's why ownership and upgradeability matter as much as today's simulation result. Re-check any token you hold if something changes, and read about proxy contracts and fake renounces.
//What if I'm already stuck in a honeypot?
Be very careful about anyone offering to help. "Recovery services" that contact you after a loss are almost always a second scam. Don't sign transactions or approvals from people promising to unlock tokens — that's how wallet drainers empty what you have left. Revoke any approvals you gave to the token's contract, report it on the platforms where it's promoted, and move on.
//The takeaway
A honeypot is a contract problem, so it's one of the few scams you can catch with certainty before you buy. Paste the contract address into TrenchScore: if the audit shows a failed sell simulation, blacklist functions, active freeze authority or an adjustable tax, the TrenchScore reflects it — and confirmed honeypots are kept out of the Trench 100 entirely.
//Frequently asked questions
How do I know if a token is a honeypot?+
Run a buy-and-sell simulation through a security scanner, check for blacklist, whitelist or hidden-owner functions, check whether taxes can be changed, and on Solana confirm that freeze authority is revoked. TrenchScore runs these checks automatically on every token page.
Why can't I sell my token?+
Common causes are a honeypot contract (blacklist, freeze, sell restriction), a sell tax raised close to 100%, a frozen token account on Solana, or simply no liquidity left in the pool after a rug pull. Check the token's contract audit and liquidity before trying anything else.
Are honeypots only on Ethereum and BNB Chain?+
No. EVM chains use blacklists and tax tricks, while Solana tokens can trap holders with freeze authority or Token-2022 extensions like the permanent delegate. Every chain needs its own checks.
