wallet VS metamask-extension

Not a stupid question. This actually happened https://github.com/bitpay/wallet/issues/9346

the BitPay Copay wallet was vulnerable to private key exfiltration due to a anybody-can-play policy in the Node.js repository. A commonly used function library was abandoned by its developer, taken over by a new developer (by mutual agreement). The new developer added some code which exfiltrated private keys from the Copay wallet when this general-purpose library was being called from the Copay app. Copay was safe one day, a theft wallet the next https://github.com/bitpay/wallet/issues/9346

You shouldn't be storing your coins (or withdrawing to) on an online service. At the very least, use a mobile wallet like this one: https://bitpay.com/wallet/

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.

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].
