Nestable NFTs

The concept of nestable NFTs refers to NFTs being able to own other NFTs.

At its core, the principle is simple: the owner of an NFT does not have to be an externally owned account or a smart contract, it can also be a specific NFT.

The process of sending an NFT into another is functionally identical to sending to another user. The process of sending an NFT out of another NFT involves issuing a transaction from the address which owns the parent NFT.

Some NFTs can be configured with special conditions for parent-child relationships. For example:

  • some parent NFTs will allow the owner of a child NFT to withdraw that child at any time (e.g. virtual land containing an avatar)
  • some parent NFTs will be prohibited from executing certain interactions on a child (e.g. the owner of a house in which someone else's avatar is a guest should not be able to BURN the guest... probably)
  • some parent NFTs will have special withdrawal conditions, like a music NFT that accepts music stems. The stems can be removed by their owners until a certain number of co-composers upvote a stem enough, or until the owner of the parent music track seals and "publishes" it

The concept of nested NFTs is further expanded through the idea of equippability.
