Upload to IPFS

What is IPFS?

In general, blockchains do not store large quantities of data (onchain) because it is quite expensive. Instead of storing the content of your image or video on the blockchain, you’ll want to store the content on IPFS (offchain) to be decentralized, and provide the IPFS URI to your content in the metadata of the NFT token.

The easiest way to upload your content to IPFS is through the use of Pinata, a 3rd party IPFS storage company.

NFT MetaData

For NFTS - you will have to upload two folders. A folder containing all the jsons metadata of your collection. Another folder containing the images like the picture above.

Metadata is a JSON file which allows applications like OpenSea, Rarible and other Marketplace to pull in the data for digital assets and easily display them in-app. Though different platform have their meta data standard, here is a link to opensea standard.

The metadata should look like this for a single file:

{
"name" : // Collection Name
"description": // Description of your collection
"image" : // URL to image on IPFS
}

{
"name" : "My First Upload",
"description": "my first upload",
"image" : "ipfs://QmYmfHMJiEipeXC94iGHPixR4jcDDUP4CcQNTiFWMk6iNb/1.png"
}
