EternalNFT VS openzeppelin-contracts

This is awesome and really well done! This is the first tutorial I've seen with testing which is super helpful. Also THANK YOU for providing the github source code (I'm surprised so many tutorials don't). One thing I could suggest, would be to add a bit more explanation around the hardhat.config.js file. I know it's pretty self-explanatory, but the hardhat stuff felt like a blackbox to me when I was learning. Maybe add another network like kovan or something and show how easy it is to deploy to either kovan or rinkeby? I remember my mind was blown when I realized how easy it was to deploy to any EVM based chain. Seriously though, thanks for this. It's honorable of you to spend so much time building out comprehensive tutorials and sharing them freely like this.

Lets look the events of Open Zeppelin’s ERC20 token contract:

ERC-777 is difficult to implement properly, due to its susceptibility to different forms of attack(opens in a new tab). It is recommended to use ERC-20 instead. This page remains as a historical archive.
