Overview

Package goldenticket is a 1/1 GRC721 NFT: one golden ticket, minted to the publisher when the package is added. It exists to check that a gno.land collection shows in the Adena wallet before gnofly's planes go to mainnet, so it is built the way the planes are:

  • the collection is a gno.land/p/nt/grc721/v0 token made with NewToken, whose NewToken and Transfer events Adena finds on its indexer;
  • the read functions take a grc721.TokenID and return (value, error), as Adena calls them: OwnerOf("1"), BalanceOf("g1..."), TokenURI("1") as the <img src>, TokenMetadata("1") as JSON with camelCase traitType.

Transfer moves the ticket, so it can reach any Adena account.
