Paste a Base contract address. Get honeypot, tax, liquidity, and risk score. $1 per scan.

What it does

Scans a smart contract for the red flags that precede a rug or a loss (dangerous permissions, owner backdoors, honeypot patterns) before you approve it or send it funds.

How it works

  1. Open the tool and provide a smart contract address or source.
  2. Pay $1: by card, or with x402 if you’re an AI agent. No account, no signup.
  3. Get a report of risk signals back, right away.

Prefer to do it yourself?

You can read the Solidity yourself if you know what to look for. This surfaces the common risk signals quickly so a non-expert isn’t flying blind.

Why it’s worth $1

The free options are either fiddly or sketchy: half of them want you to upload a private file to a server you’ve never heard of, behind a wall of ads. We don’t. There’s no account, no signup, and your file isn’t stored or reused after the job runs. You pay a dollar, you get the result, and that’s the whole relationship.

Frequently asked

Is a clean scan a guarantee it’s safe?

No. It flags known risk patterns, but no automated scan can promise a contract is safe. Treat it as one input, not the final word.

What does it look for?

Risky permissions, ownership backdoors, and patterns associated with honeypots and scams.
