This directory has a few prominent ERCs implemented in TokenScript. Unlike a typical tokenscript, these TokenScripts do not have smart contracts defined in them, and each token's tokenscript can choose to override the named cards and named attributes defined in these TokenScripts.
As of Jun 2020, these ERC implementations have the token attributes defined in each ERCs and activity cards, but no token cards or action cards. These will be amended in the coming months.
