goldenticket/v2 package

Overview

Package goldenticket is a 1/1 GRC721 NFT: one golden ticket, minted to the publisher when the package is added. It checks that a gno.land collection shows in the Adena wallet, built the way gnofly's 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.

v2 of goldenticket: the image is no longer a constant. The publisher is the admin and moves it with SetImage, as the planes' SetImageBase does, so it can live where both Adena (any https: image) and gno.land's pages (an allowlist: GitHub, imgur, IPFS) load it.

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

Result

Name

func Name() string
Ask AI Claude ChatGPT

Result

SetImage

func SetImage(cur realm, url string)
Ask AI Claude ChatGPT

SetImage points the ticket at another image, at once: TokenURI is computed on every read. Admin only, by a direct call.
