Asset tracking and movement
NFTs can be transferred just like regular ERC-20 tokens. The standard provides modified transfer and approve functions for token transfer and delegation tasks. It also includes the standard event logging facility so that asset tracking can be made easier.
In this recipe, you will learn how to implement asset movement and tracking functionality in the ERC-721 token created in the previous recipe. Token transfer functionality can be achieved by modifying the standard transfer method and asset tracking can be implemented with event filtering.
