EIP-721 2 includes an optional metadata extension with a name
, symbol
and for each tokenID a tokenURI
with can point to a JSON file with name
, description
and image
for the given token ID.
For testing purpose, we can use My JSON Server 6 where we can store a single JSON file in a GitHub repository that we can access via a fake JSON server.
For production we need to store our metadata in a permanent location that can exist for the life of the token.
For images we will use twemoji Graphics from twitter/twemoji 2 which are licensed under CC BY 4.0
A sample JSON for tokenID 0 is: http://my-json-server.typicode.com/abcoathup/samplenft/tokens/0 8
