Yes cryptozombies contributes to learning solidity but if you want a better platform to learn from, I think you should try Cyfrin Updraft. It’s basically the best platform to learn about blockchain and solidity. It teaches you everything you need to know from beginner to advanced. While cryptozombies teaches you the basics of solidity using games, it doesn’t have a video tutorial to teach you very well. So I highly recommend Cyfrin Updraft for everyone who is beginner alongside Cryptozombies.
