Several people asked me yesterday how to read the code for NFT smart contracts, so here's a brief thread on how I do it.
1/ First go to @opensea and find an NFT you want to review and click into its details section. In there you'll find a link to the contract on Etherscan. 
2/ Click that link and you'll land on the Contract Overview page. Find the tab that says "Contract", and if it's got a green check mark you can get excited because it means the developers uploaded code for you to read.
3/ If there's no green check, you have the option of decompiling the byte code, but that output isn't pretty and it's no fun to read. You're better off just bugging the developers to verify their contract on Etherscan.
4/ Once you get to the Contract tab, check the Contract Source Code format. If it says "Solidity" that means the developer uploaded one big file, and you'll have to search that massive text box to find the good stuff.
5/ Scroll all the way to the bottom, and then start scrolling up until you find the contract definition. This is usually the only interesting contract, and the rest are open source includes.
6/ If the Contract Source Code format says "Standard Json-Input" then you're in luck, the developer uploaded multiple smaller files and you're going to have a fun time reading through them.
7/ To any developers looking for a simple way to verify their contract, I ended up using the github.com/rkalis/truffle… plugin, since I'm using Truffle. I'm sure there are even simpler ways to do it in Hardhat though!
8/ Hope this helps those of you looking to start exploring contract land. Let me know if you have any questions or find anything interesting!
9/ And finally, make sure to give my NFT project a follow: @mystoners We’re dropping in 5 days on International Rock Day!
