NFTs are uniquely identifiable digital assets on Convex
Each NFT may define metadata which is accessible on-chain on a per-NFT basis
Metadata SHOULD be expressed as a Convex data structure value that is representable as a JSON Object
This implies that the following values are permissible:
- A Hashmap with Strings as Keys
- A String
- Boolean values
- A Vector of values
- Numbers (must be a small integer or double precision floating point value to fit within valid JSON ranges)
nil
{
"name" "Bob"
"image" "http://foo.com/image1.png"
}Which would be equivalently expressed in JSON as:
{
"name": "Bob",
"image": "http://foo.com/image1.png"
}Metadata MUST be accessed using the following interface either directly or indirectly:
;; Using scoped actor
(call [nft-actor nft-id] (get-metadata))
;; Using a argument
(call nft-argument (get-metadata nft-id))
NFT implementations MAY either generate metadata dynamically on demand or store metadata on-chain.
