Links for Days โ€” Why let your connection with your fans stop at the NFT purchase? In addition to all the amazing things you can do on WAX Blockchain, such as incentivizing your collection holders through, you can link to other places online to buy, like your print on demand of your art or just your social media to get more followers.

By following this schema, Music NFT creators can maximize their compatibility with existing platforms while retaining forward-compatibility.

This blog post will provide a full overview of the WAX NFT Metadata Standards, including technical details, instructions for use, and examples of how to modify the schema for custom projects.

About the Standard

Compatible with Atomic Assets, itโ€™s as a defined as a schema (now called category) within the Atomic Assets NFT standard on the Atomic Assets contract.

By utilizing this schema, any individual, collection, or application can create their own music NFT projects on platforms like Atomichub and Neftyblocks.

The standard allows creators to make the needed schema (called category on the new Atomichub website) for music NFTs quickly and efficiently. Creators are encouraged to use and modify the standard for any purpose in line with the open source MIT license.

  • Media fields like images, audio, and video are stored using IPFS hashes. Images can also be uploaded directly through Atomichub.
  • Get free IPFS hosting from services like Piรฑata.
  • Information fields like title, artist, album, etc. are stored as strings (except for the track number which is an integer).
  • Geographic fields for country, locale, and geotag follow standard formats:
  • ISO 3166โ€“1 alpha-3 3-letter codes for country
  • Locale as โ€œCity, State, Countyโ€
