In theory you can do this now by exploiting front-running bots, see https://github.com/flashbots/pm/issues/24

Front run + back run is sandwich. Front running has also been called miner extractable value. This is now called maximal extractable value.

You may want to look a little further, or not.

2: sponsored transactions. use flashbots to send transactions directly to miners using a third party address as payment.

I know someone who runs a MEV-Bot, i.e. scanning the mempool for opportunities and bribing miners to include his arbitrage-tx into the chain via FlashBots.

> “Less trust, more truth.”

What a neat platitude that means absolutely nothing. As a society, over, oh I don't know, like 5000 years, we figured out the the best way to enforce truth is via some sort of centralized institution: the court of law.

> They could, right. They sort of do—there’s the star thing that you can only do once per day. But guess what? They're a profit-motivated company. So if you pay Tinder enough, you can just send as many stars as you want.

Wait, crypto miners aren't profit-motivated? Maybe we should introduce Mr. Wood to flashbots[1] -- a "sub-network" of Ethereum miners (a fork of geth) who's entire purpose for existing is front-running. Truth as long as you can pay for it -- got it. Web3 is end-stage capitalism and we've been down this road in the early 1900s. Yawn.

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].
