Fractional NFTs

Problem

A holder of a NFT that has gained in value wants sell a portion of a NFT they hold. Perhaps the value is so high, but they want to keep a portion of the NFT.

Solution

Separate the original NFT into smaller piece (user defined amount). The original NFT can be returned by any address that owns all of the original pieces.

How it Works

  • An owner of an NFT want to sell a portion of that NFT
  • The owner will send that NFT to an contract address with the specified number of piece they want to divide the NFT into
  • The smart contract will send back (using EIP-1155) the specific number of newly minted NFTs
  • Any user that holds all the portions of the original NFT, may retreive the original NFT by exchanging all the original pieces (which will be burned)

More Advanced

  • Allow divided items to be further divided

Challenges

  • Validate security of contract holding original NFTs
