Hierarchy

Hierarchy is one of the pillars of our architecture, it defines abstraction on top of all supported token standards

Hierarchy of entities consists of 5 levels, some entities does not make sense, so they are virtual

	NATIVE	ERC20	ERC721	ERC998	ERC1155
contract	✔	✔	✔	✔	✔
template	✘	✘	✔	✔	✔
token	✘	✘	✔	✔	✘
balance	✔	✔	✘	✘	✔
composition	✘	✘	✘	✔	✘

For example token entity of ERC20 and ERC1155 has no metadata thus they have no template, as well as balance entity for ERC721 and ERC998 always has amount equal to 1
