Items Metadata Standards

Here you can find an example of Metadata json standard, using the ETHITEM front-end best practices:

{
    "image": "https://ipfs.io/ipfs/QmNa3W2xEEAZhCSmSp3pzuvRD3vC2Tr7mzg8SvdwssYKCZ",
    "image_data": "ipfs://ipfs/QmbJWAESqCsf4RFCqEY7jecCashj8usXiyDNfKtZCwwzGb",
    "description": "Seiya",
    "background_color": "#951d1d",
    "file": "ipfs://ipfs/QmbJWAESqCsf4RFCqEY7jecCashj8usXiyDNfKtZCwwzGb",
    "folder": "ipfs://ipfs/QmbJWAESqCsf4RFCqEY7jecCashj8usXiyDNfKtZCwwzGb",
    "license_url": "ipfs://ipfs/QmbJWAESqCsf4RFCqEY7jecCashj8usXiyDNfKtZCwwzGb"
}

--- “image”: Cover of the Collection (valid URL pointing to the image to use as cover), max-width is 350px and max size of 5MB [NFT Shared Standard] [mandatory]

--- “Image_data”: Raw SVG image data, if you want to generate images on the fly (not recommended). Only use this if you're not including the image parameter. [NFT Shared Standard] [optional]

--- “description”: A human-readable description of the item. Markdown (and raw HTML) is supported. [NFT Shared Standard] [Mandatory]

--- “background_color”: Background color of the item. Must be six-character hexadecimal without a pre-pended #. [NFT Shared Standard] [mandatory]

--- “file”: IPFS link of a single HTML page [optional]

--- “folder”: IPFS link of static HTML site [optional]

--- “license_url”: IPFS link to the license file

Note: When passing the JSON externally it should follow this same approach (aka start with the IPFS protocol) ipfs://ipfs/QmVyPrsDrfwRbJgZYy1mRmb5qYPpPJFx2CUxPMTCoUmv6V

This requirement guarantees total compatibility with NFT Shared Standards. This should be the form followed by the URI returned by the “uri()” method.
