 GenITeam’s developers who worked on this collaboration are neither smart contract nor Move developers. Based on their input, we created a data model and shared simple APIs. With these APIs, geniteam was able to mint fully on-chain NFTs that are mutable, own other on-chain assets, and freely transfer to other applications.
