What is a honeypot token? How to check if you can sell a memecoin

By Blockchain Lab · Published 12 Oct 2026 · Updated 2 Nov 2026

A honeypot is a token whose contract lets anyone buy but stops most holders from selling — through a blacklist, a hidden "only owner can sell" rule, a 99% sell tax, or a transfer function that fails for everyone except whitelisted wallets. The chart keeps going up because only buys succeed.

How to detect one without risking money

Simulate the trade. A simulation runs buy → approve → sell against the live chain state without sending a transaction. Each EVM token page here runs three independent simulations:

• honeypot.is — fork-based simulation with tax estimates.
• GoPlus — static and dynamic contract analysis (honeypot flag, taxes, blacklist, owner powers).
• On-chain eth_call — the open-source honeyCheck contract (MIT, forked to Blockchains/web3-defi-honeypot-and-slippage-checker) buys with 0.5 ETH/BNB through a v2 router and sells straight back in a single read-only call. A round-trip loss of about 0.6% is normal (two pool fees); anything much higher is a tax.

Limits

Simulations can be fooled by contracts that behave differently for simulators, by time-based switches, or by owners who change rules after you buy. Treat a pass as "not obviously a honeypot right now", not as a guarantee. Solana SPL tokens cannot hide sell logic the same way, but freeze authority, Token-2022 transfer hooks and permanent delegates create equivalent risks.

FAQ

What is a honeypot token?

A token whose contract lets you buy but blocks or heavily taxes selling, through blacklists, owner-only rules or extreme sell taxes.

Can Solana tokens be honeypots?

Classic SPL tokens cannot run custom sell logic, but freeze authority and Token-2022 extensions such as transfer hooks or permanent delegates can have a similar effect.

How do I test if I can sell a token?

Simulate a buy and sell without sending a transaction. Token pages here run honeypot.is, GoPlus and an on-chain eth_call simulation.
