I’d like to introduce the recently proposed Non fungible property standard.
TLTR: This standard added some extensive user classes like tenancy or lien in addition to ownership of the ERC721 standard. These features make rental or collateral without escrow possible.
Here is the link to details.
I’d love to hear your feedback.
If you like to implement this standard to your project and have some personal questions, DM me https://twitter.com/KOHSHIBA
