Most people find out a contract was a trap after they are already in it. Paste the address first and read it straight from the chain: whether selling is even possible, who still controls the supply, and what the people who deployed it built before.
No account. No wallet connection. Nothing to install.
Every trap below is written into the contract before anyone buys, and every one of them is readable in seconds.
Almost always because the contract was written that way, not because of your wallet or the network. A contract can block transfers outright, pause trading, blacklist addresses, or set a sell tax so high that selling returns nothing. Every one of those conditions is readable in the contract before you buy, which is what this check looks for.
A token you can buy but cannot sell. Purchases go through normally, so the chart looks healthy and the holder count rises, while disposals are blocked or taxed to zero. The trap is in the contract's transfer rules, and it is visible from the moment the contract is deployed.
Paste the contract address above. The scan reports a dedicated honeypot check — whether you would be able to sell — plus the related traps: transfer restrictions, blacklist and whitelist functions, and the exact buy and sell taxes the contract charges.
On some contracts, yes. An owner who has not renounced ownership may retain powers such as minting new supply, pausing transfers, or altering balances. The scan reports ownership as renounced, active, or a backdoor, so you can see what the deployer can still do to you.
It means whoever provided the liquidity can withdraw it whenever they like. When they do, there is nothing left to sell into and the token's price collapses to nothing — the mechanic people call a rug pull. The scan reports whether liquidity is locked and how much of it.
No, and you should be wary of any tool that asks. Reading a contract needs nothing but its public address. Connecting a wallet grants permissions that a read-only check has no use for.
