Composition

The ERC998 token is a valuable addition to the existing standards, it enables a whole new range of use cases. Main feature of ERC998 is an ability to be composed. This means each ERC998 token can own another tokens (ERC20, ERC721, ERC998 or ERC1155) as a child. Composed tokens can be traded in a single transaction for a cost of transfer of parent token.

Configuration

While it looks like a good idea to add each and every token as a potential child, in real life application it is most likely impossible to wear CryptoKitty as a helmet of your character, because there is no such texture in the game. Another thing is about amount of children of the same type, i.e. wearing 10 helmets at a time does not seem reasonable.

Configuration options

We offer a filter to apply custom rules to restrict children.

• parent - parent contract
• child - child contract
• amount - amount of child tokens

NOTE: operations of adding and removing rules are performed directly on blockchain and reflected in database after transaction is complete
