Questions people actually ask
Do I need to connect a wallet?
No. Checks require no wallet connection, which matters in a space where wallet connection is itself an attack vector.
What does a check cover?
Whether the artwork is original, whether the contract permits the creator to alter or revoke, transfer restrictions and royalty behaviour, wash trading, creator identity where it exists, and where the assets are actually stored.
How is copied artwork detected?
Through reverse image search across the web.
Does it work on any marketplace?
It works on any listing, anywhere.
What does it cost?
Individual checks are free and unlimited. Portfolio monitoring is 15 dollars a month, and API access is 690 dollars a month.
What does monitoring do?
It alerts you when a held asset's contract or storage changes.
Is there an API?
Yes. The API is for marketplaces and custodians screening listings at scale, at 690 dollars a month.
Why should I trust the pre-purchase listing check?
The score counts the checks you say you have done, in your browser. It does not inspect the listing or contract, it is not investment advice, and a high score does not make a purchase sound. The free checker examines a listing or contract address and shows its evidence.
What should you verify before you buy a digital collectible?
Answer sixteen questions about a listing you are considering: the artwork, the contract, trading activity, the creator, and storage and your own safety. See which checks are done and what to look into next. Runs in your browser. No account, no card, no call.
