NFT Metadata Contract

The ViewResolver and MetadataViews contracts implement a standard to attach on-chain metadata to NFTs. This standard was originally proposed in FLIP-0636.

It is deployed at the same address as the NonFungibleToken contract interface.

There exists a tool, Flow NFT Catalog, which enables dapp developers the ability to unlock interoperability of your NFT collection across the Flow ecosystem. This will help make your NFT collection’s metadata more discoverable and interoperable.

To optimize your NFT collections for this catalog, you’ll need to:

  1. Update your NFT contract to support ViewResolver and MetadataViews with implementation of the core NFT views.
  2. Deploy the updated contract to both testnet and mainnet.
  3. Afterwards, onboard your NFT to the Flow NFT catalog at https://flow-nft-catalog.com.
