lil-web3 VS openzeppelin-contracts

What's the hungup with normal tutorials? There's a plethora of tutorials online.

People recommend ethernauts and cryptozombies, but I found those quite slow when I was learning. Most useful for me was reading existing implementations of smart contracts, and learning from there.

M1guelpf wrote these a while ago, might be helpful examples: https://github.com/m1guelpf/lil-web3

happy to chat if you need help

If you’re trying to get started, lil-web3 is a github repo with lots of simplified versions of popular smart contracts. It should help you to grasp the core functionality before you try to understand all of the other content in each contract.

thirdweb is a pretty easy way to get started if you’re an experienced web developer. we use them internally at our web3 dev education startup for creating and sending nfts to folks who complete our tutorials.

we have a tutorial with them going on where we show you how to build a full stack web3 app with their sdks/platform. we’re rewarding folks who complete the tutorial with a bit of $MATIC and a cool nft[1]

another cool resource after you get your feet wet is this collection of tiny examples of popular web3 apps[2]

beyond tutorials i also think learning by trying to build your own version of other projects is a pretty cool way to progress. Here's a cool repo that does this https://github.com/m1guelpf/lil-web3 , the author builds out mini version of ENS, opensea, etc

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.
