EIPs VS metamask-extension

Even more relevant would be the Ethereum Improvement Proposal repo (where people submit proposals to change the spec):

https://github.com/ethereum/EIPs

Or the go-ethereum execution client (the most popular execution client):

https://github.com/ethereum/go-ethereum

It’s early in the life of the xERC20 standard, but progress is quickly being made. The standard has been audited and is already live with a few projects. The EIP to adopt the standard has been created, and implementation has begun. Alchemix recently announced support for the xERC20 standard. And Defi Wonderland has published a suggested implementation on their GitHub. This implementation has an interface for the xERC20 contract with eight core functions that the token issuer must implement. These are functions related to setting the Lockbox contract (setLockbox), issuance limits for bridges (setLimits, mintingMaxLimitOf, burningMaxLimitOf, etc.), and the core mint and burn functions.

ERC223 is not widely implemented, and there is some debate in the ERC discussion thread about backward compatibility and trade-offs between implementing changes at the contract interface level versus the user interface.

Ethereum Improvement Proposals (EIPs): These are proposals to change various aspects of Ethereum. They often contain detailed technical discussion and can be a good resource for understanding the finer points of how Ethereum works. EIPs can be found here: https://eips.ethereum.org/

Worth looking at: EIP6968: Contract Secured Revenue on an EVM based L2 https://github.com/ethereum/EIPs/pull/6969/files

Additionally, I have made an EIP that can help standardise and maintain official contract registry of each DApp. This can help identify official contracts of a protocol vs scammers using fraud contracts but presenting like official protocol. https://github.com/ethereum/EIPs/pull/6807

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].
