In 2022, cross-chain between BNB Beacon Chain and BSC was exploited because of Zero Day vulnerabilities in the Cosmos SDK. The hotfixes (1.1.15 and 1.1.16) are implemented with almost zero direct impact on users and dApps.

BNB Smart Chain Mainnet is expected to have a scheduled hardfork upgrade named Gibbs at block height 23,846,001. The current block generation speed forecasts this to occur around 12th Dec. 2022 at 10:00 AM (UTC). The validators and full node operators on Mainnet should switch their software version to  v1.1.18 by 12th Dec.

1. BSC Release v1.1.16 - BSC v1.1.16 is a temporary urgent patch to mitigate the cross-chain infrastructure between Beacon Chain and Smart Chain so that the cross-chain can be re-enabled back.

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].
