Drop Metadata Renderer

Metadata rendering contract for NFTs with individual media assets

This contract is in charge of managing and rendering the metadata for Zora drops. A drop is an NFT collection where all the NFTs have individual media assets.

Whenever a tokenURI is called on an NFT contract it is forwarded to this contract to get metadata for a specific NFT.

View the source contract code here and the list of deployed contract addresses here.

  • baseURI: A common base path that all the assets share and can append the tokenId to the end to get the metadata for an NFT.
  • contractURI: A resource for getting metadata for the contract. Follows the contract-level metadata format described here.
  • provenanceHash: A hash that is used to prove that the order of the images and metadata was set pre-mint, and was not manipulated.
  • target: The address of the NFT contract to get data for.
