Contract FungibleTokenMetadataViews


_10
contract FungibleTokenMetadataViews {
_10
}

This contract implements the metadata standard proposed in FLIP-1087.

Ref: https://github.com/onflow/flips/blob/main/application/20220811-fungible-tokens-metadata.md

Structs and resources can implement one or more metadata types, called views. Each view type represents a different kind of metadata.
