The whole library exists with the new syntax: https://smartpy.io/ide?template=fa2_lib.py

There are tests with the three base classes with all available policies and mixins:

Also the two standalone minimal version, not intended for real usage but a good place to learn how it works:

There are two limitations at the moment:

  • the base metadata is not generated so you cannot have the offchain views in your metadata
  • there is no current way to inherit from a contract of another module so you have to use one of the contracts given by the library or copy the whole library and create a contract inside the library's module that inherits from a library's module.

These two limitations may disappear in a new version.
