Metadata Replace our URL and Twitter with yours below. {"721":{ "##policyID##": { "##ticker##": { "name": "##tokenName##", "image": "ipfs://Q..put.cid.here", "nsfw": "False", "copyright": "Copyright @2021", "Version": "1", "id":"1", "collection": "", "url": "https://www.metromermaids.com/", "Twitter": "https://twitter.com/_mermada", "Instagram": "" } } } } Take a look at this Metadata example and guide Please respect our community and set the nsfw to True if this applies. To define a NFT, you can add custom properties above. Variables are needed for proper format. ##policyID## is generated when your token is minted. ##ticker## and ##tokenName## are taken from the form input. You generate the ipfs hash and arweaveId on your own, very easy, just use a free tool like: https://pinata.cloud/ or https://globalupload.io/(research ongoing, coming soon?)

How many to Mint:

Lock Policy - No future minting or burning or metadata updates

Example #1 Metadata:
{"721":{ "abacadabaabacadabaabacadabaabacadabaabacadabaabacadabaab": { "Fred": { "arweaveId": "...", "image": "ipfs://...", "name": "Fred Token", "traits": [ "Programmer", "Kindness" ], "type": "Human?" }}}}
In the example above, you do not specify the policy id (abacadaba part) that is created by the system when you mint the token. We use a placeholder of ##policyID## to specify where this is placed. This allows you to adjust the specification with this tool if needed.

Example #2 Metadata:
{"721":{ "abacadabaabacadabaabacadabaabacadabaabacadabaabacadabaab": { "TokenTicker": { "arweaveId": "...", "image": "ipfs://...", "name": "Full Token Name", "weapons": [ "axe", "dagger" ], "weakness": [ "Kindness" ], "type": "Warrior", "stamina": "888" }}}}
In the example above, I just tried to make up another more complicated profile, the fields are up to you but just putting anything here does not do anything, being an advanced use case, this is meant for people who know how the NFT will display these properties if it is used in a game or on a market place that supports these types of attributes.Pro Tips!

Search for examples of metadata to get ideas of how others are using it with this tool.

I found this on the NFT standard posting so I included the image of the person who created it as reference.
