The mark

What the khaki check means, what it costs, and what it deliberately does not say.

The owner of any NFT collection on Robinhood Chain can pay in $NIGHT to put a khaki check beside its name here. It works for collections made on Nightgarden and for collections made anywhere else: the register asks who is calling, not where the contract came from.

What it means

One thing, and the interface says it in these words rather than leaving the word *verified* to do the implying: the address that controls this collection paid, on this date. It is a receipt.

It is not a safety rating

Nobody reviewed the collection. We did not look at the art, the contract, or the people behind it. A paid tick reads as an endorsement — it is what happened to the blue one the week it went on sale — and this one is not.

What nobody can do, including us

  • Buy somebody else's mark. The caller has to be the collection's owner() or creator(). Without that, a rival could mark a drop they have nothing to do with, or a scammer could mark a real project to borrow its credibility.
  • Take a mark away. There is no revoke, no pause, and no owner with a delete. A register we could edit would be our opinion with a price on it, and a creator who paid could lose what they paid for because we changed our mind.
  • Collect the fee. It goes to the dead address in the same transaction. There is no function in the contract that could send it anywhere else.

The second of those has a cost worth naming rather than discovering: a collection that turns out to be a fraud keeps its mark. The site is allowed to say so beside it. The register is not allowed to lie about what was paid.

Buying one

Connect the wallet that owns the collection and open its manage page. The panel only appears for that wallet, because the contract only accepts that wallet. Two signatures: an allowance for the fee, then the mark itself.

Until $NIGHT launches, the register refuses to mark anything at all rather than handing marks out for free. Free marks issued in that window would be indistinguishable afterwards from ones somebody paid for, which would make the whole register worthless.
