Advanced Plutus fractionalized NFT protocol which supports "NFT Bag" functionality.
The code on this repository has not been audited. We don't recommend it using in production without a full security audit. Use it at your own risk!.
This contract locks an NFT and mints a number of tokens representing fractions of it. To get the NFT back, the fraction tokens are burned.
The protocol has three steps:
- Locking the NFT: The NFT is paid to the contract
- Mint tokens: Fraction tokens are minted (must be run by the same person who performed step 1).
- Return the NFT: Burning all the fraction tokens will allow the user to redeem the NFT back.
