Every week, someone loses savings to a token they could not sell. Not because they picked wrong on fundamentals — because the contract was designed so that selling was never possible.
Here is the mechanics-first guide I wish those people had read at 1 a.m., plus the exact checks I run before any trade.
What a honeypot actually is
A honeypot is a smart contract that allows buys but blocks sells for everyone except privileged wallets. The buy button works. The chart goes up. The sell button fails with vague errors — or silently does nothing.
The trick is caller inspection: transfer behaves differently depending on who calls it. Sellers revert or get taxed at 100%; the owner's wallets move freely. Modern versions hide this behind proxies and external calls, which is why reading bytecode rarely saves you.
The 60-second pre-buy checklist
Run these five checks on every new token, especially ones trending on social feeds:
- Sell simulation. Can an unrelated wallet actually sell? This single test kills most traps. Simulation beats code reading because obfuscated logic still has to behave one way or another.
- Mint authority. If the contract can mint unlimited supply, your position can be diluted to dust in one transaction.
- Owner concentration. An active owner holding double-digit percentages of supply — or hidden ownership — means every rule you read today can change tonight.
- Liquidity control. $2M of liquidity held by one wallet is more dangerous than $20k burned forever. Concentration answers "who can pull"; depth only answers slippage.
- Tax mutability. Buy/sell taxes that are owner-modifiable are levers waiting for maximum holder count. Per-wallet slippage modification is the precision instrument of targeted traps.
Three or more red flags together are a pattern, not noise.
Why your wallet never warns you
Wallets sign transactions; they do not simulate outcomes. Nothing in MetaMask distinguishes a tradable token from a trap. Social proof does not help either — on meme-heavy chains, social consensus is literally the product being sold to you.
Tools
You can do all five checks manually against explorers, or automate them. I use RugRadar — full disclosure, I built it — which runs the sell-simulation, mint/ownership, LP-concentration and tax-mutability checks across Ethereum, BSC, Polygon, Arbitrum and Base, and explains every finding in plain language instead of raw flags. The scanner is free; there is a paid tier for bulk/API use, which matters if you degen more than occasionally.
Whatever tool you use, the discipline is the same: simulation first, concentration second, taxes third — before size goes on.
The uncomfortable summary
Most rug victims were not unlucky; they skipped thirty seconds of checking under hype pressure. The market pays for speed, but it collects from people who confuse speed with diligence.
Stay safe out there. Paste the address before you paste your seed phrase into regret.
