An Introduction to the Non-Fungible Tokens (NFTs)

Description

In this tutorial, we are going to introduce the Non-Fungible Tokens or ERC-721 standard. In addition to that, we are going to get familiar with the interface of ERC-721 so that we can later use them in NFT deployments. Every NFT project also needs an ERC-721 JSON metadata that we are going to introduce in different sections.
