# Metadata

## What is Metadata?

Metadata is a JSON file that points contains the image, properties, and other associated information that makes an NFT an NFT. 

## Opensea Standard Metadata

As the Opensea API is the current nexus of the centralized NFT space, it is important our Metadata is formatted in a way that Opensea can aggregate. 

Places like Twitter and Metamask et al do not look for NFT metadata directly on the blockchain, but instead rely on the Opensea API to pull metadata. 

**Metadata for non supported EVMs**

This brings up a conundrum when minting NFTs on chains such as Binance Smart Chain. The metadata standard for Binance is different than Opensea, and Opensea does not support BSC currently. 

## Bulk Uploading Metadata via CSV

To create NFTs at scale, we need a way to bulk upload our Metadata.

As each metadata JSON file is a discreet object, the minimum viable way of accomplishing this is through a CSV file. 

Our system will automatically create properly formatted JSON files and append the blockchain to an IPFS url where each JSON is uploaded.
