Generic FA2

Experiment with generic FA2 contracts.

Original contracts code:

Token metadata

Because temple wallet and better call dev platform follows a FA2 standard (with multiple assets), the single_asset follows the same type definition of the token metadata than multi_asset. Thus the single asset handles only one asset, it defines the token metadata as a big_map which contains a single entry. For example:

  Big_map.literal ([
    (0n, { token_id = 0n; token_info = Map.literal([ ("", 0x03) ]) })
  ])
