Minting

On the “create” tab there is a dropdown menu listing the contract(s) you can mint from.

Mandatory fields

- amount (1 for unique, up to 50 for editions) - name (title of your artwork) - description (additional information) - main image (up to 5 Mb)

Optional fields - category & tags (can be good for searching) - media (if your artwork is a video, audio, 3D, or vector file) - royalties (highly recommended, this ensures you will get paid on secondary sales) - split revenue (for the primary sale) - date (this is for events or tickets) - document (if you want to include a PDF, like a certificate) - location (this is for events or tickets) - website (any URL. optional) - custom (anything not covered by the above)

When you press mint you will be directed to your wallet and submit a transaction. It takes a few seconds for it to be validated and included in a block.

The images, files, text and all the fields you filled in are called “token metadata” and they are stored on a separate blockchain called Arweave. The unique token id, the minter wallet, the royalty and splits percentages are stored on the NEAR blockchain, as well as the Arweave hash address for all the media and metadata.

Metadata is all the information associated with a non fungible token. A cryptographic signature of this data, also knows as a hash, is generated and stored in the blockchain in the minting transaction. This serves to authenticate the digital files connected to a token. If even one pixel of an image is changed, its cryptographic hash will not match anymore the one secured in the blockchain.
