MintMark inspects any token on its blockchain, then issues a graded, tamper-evident certificate of authenticity — independently verifiable by anyone, signed by no one you have to trust.
A hallmark on silver records who assayed it and that the metal is true. MintMark does the same for a token — reading four independent signals straight from the blockchain, then grading what it found.
Is this the official contract for the collection — or a look-alike minting the same art elsewhere?
Is the artwork stored immutably, or on a server where it can be swapped out after you buy?
Who holds it right now, read live from the ledger — the one fact the chain can never fake.
Where it came from: the mint origin and the chain of hands it has passed through since.
Like a coin or a card, an asset earns a tier for how much MintMark could confirm. Even a modest grade means the token is real; the grade tells you how completely it checks out.
Every signal confirmed: official contract, permanent art, clear ownership, traced origin.
Sound and well-behaved, with a single signal left unconfirmed — often canonical status.
Real and on-chain, but with caveats worth a closer look before you rely on it.
No contract, or a token that was never minted. Not a grade — a stop sign.
Cut counterfeit-collection fraud on your listings and give buyers a reason to trust them. One API call per token; an embeddable mark per listing.
Inspect a token before you buy and keep a signed record of what was true the moment you did. Watch the assets you hold for quiet changes over time.
