This repository contains a minimal implementation of ERC-7432 (Non-Fungible Token Roles). ERC-7432 introduces role management for NFTs. Each role assignment is associated with a single NFT and expires automatically at a given timestamp.
ERC-7432 can be deeply integrated with dApps to create a utility-sharing mechanism. A good example is in digital real estate. A user can create a digital property NFT and grant a keccak256("PROPERTY_MANAGER") role to another user, allowing them to delegate specific utility without compromising ownership. The same user could also grant multiple keccak256("PROPERTY_TENANT") roles, allowing the grantees to access and interact with the digital property.
You can find the full specification here.
