NFT Marketplace with Lazy Minting #6 Smart Contracts and Inheritence

In this episode we build an abstract NFT contract with permission roles and derive our tutorial NFT Collection from this abstract NFT contract.
We start with a short explanation on how to write smart contracts with Solidity based on an example smart contract that comes with Hardhat. You will also learn what ABIs are and why we need it.
Then we use Open Zeppelin to build the abstract NFT contract with permission roles and we show you how to derive from this smart contract by creating the Tutorial NFT collection - the Bored Ape Fake Club (BAFC).
We implement the interfaceNFT module in this video, that allows our marketplace frontend to interact with NFT contracts through their ABI.
The marketplace smart contract, that we will build in the following videos, will interact with this NFT smart contract to mint and transfer NFT tokens.
