ERC-6059 introduces the concept of one NFT owning another NFT, without the need of an externally owned account (EOA) or a smart contract. This standard extends the basic NFT standard to allow for nesting and a parent-child relationship between NFTs. In simpler terms, an NFT can own and manage other NFTs, creating a hierarchy of tokens.
In the context of ERC-6059:
A parent token is an NFT that owns another NFT.
A child token is an NFT that is owned by another NFT.
An NFT can be both a parent and a child at the same time, resulting in multiple levels of ownership.
The owner of the parent token can manage not only the direct child tokens but also their children, extending the control to multiple levels of hierarchy.
Potential Use Cases
Bundling: Group and sell multiple NFTs together as a single package, making it convenient for collectors to buy a set of related NFTs in one transaction.
Collecting: Organize NFTs in a collection based on the owner's preference, such as grouping NFTs from the same artist or theme.
Membership: Create exclusive memberships to DAOs or clubs where owning a specific NFT (parent token) grants access to additional NFTs (child tokens) like special perks or bonuses.
Delegation: Implement voting systems or delegate decision-making power within decentralized organizations by using nested NFTs as voting tokens or representation of authority.
