As a software engineer, you can create your own NFTs to sell online or use them to build virtual worlds like Decentraland. You could also develop NFT marketplaces, digital wallets, or other tools related to the NFT space.

Virtual Lands

Virtual lands are 3D landscapes built using blockchain technology. They are similar to virtual worlds like Second Life and can be used for gaming, social networking, education, and more. As a software engineer, you could develop virtual lands for users to explore or create applications that run on the platforms. You could also create plugins or tools that extend the functionality of existing virtual land platforms, or even build your own from scratch.
