Honeypot

A honeypot is a crypto token you can buy but cannot sell, because its contract blocks or confiscates the sale.

Honeypot contracts leave the buy path open so the token looks tradable, then revert or zero out any sell through a whitelist-only require check, an automatic blacklist, a balance reset, or a 100 percent sell tax. Price and volume look normal because buys succeed, so detecting one reliably requires reading the decompiled bytecode or simulating an actual sell on the live liquidity pool.
