lil-web3 VS metamask-extension

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.

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

Have an Ethereum wallet, preferably Metamask installed.

A  Metamask Account.

Plenty of projects are source-available, but not open source, and get tons of issues, and even contributions (https://github.com/MetaMask/metamask-extension off the top of my head)

You can create an attestation based on an existing schema or create your own. Schemas define the format in which attestations will be made, and in this case, we will use the Is Human schema to attest that the owner of a certain address is human. For this example, you only need to connect your Metamask wallet (or any wallet) to Scroll Sepolia, then enter the address you want to attest and click Make attestation. You can choose whether you want the off-chain attestation, i.e., free, obtained only by signing a transaction. Alternatively, you can choose to make it on-chain and pay for the transaction to make it public and connect it to smart contract logic. In this case, you will need to obtain funds in Scroll Sepolia through a Scroll Sepolia Faucet.

Metamask (9000 GitHub Stars) https://github.com/MetaMask/metamask-extension

For this tutorial you will need Metamask or other wallet of your choice, with Scroll Sepolia funds that you can get from a Sepolia faucet and then bridge them to L2 using the Scroll Sepolia bridge. Alternatively, you can use a Scroll Sepolia Faucet to get funds directly on L2.

16) Open Metamask app. In this instruction we will use Metamask extension for Chrome browser.

> I get a 3-5 sec lag on launch [0] as it prepares the browser to block ads.

uBO is typically ready in a fraction of second, so "3-5 sec" is not normal. In Firefox all extensions sit in the same process, so it's possible another extension is preventing uBO to be ready in a timely manner, this has happened[1].
