Kyber Network is a hub for liquidity protocols that collects liquidity from several sources to offer safe and quick transactions on any decentralized application (DApp). Kyber Network’s major objective is to make it simple for users to access liquidity pools that offer the best prices for DeFi DApps, decentralized exchanges (DEXs), and other users.

A greatly transformed business niche that has greatly expanded with Ethereum and DApps is the prediction market. Prediction markets are decentralized exchanges where the objects of trade are not stocks and bonds but the results of various events. It can be like a decentralized sports betting exchange, which used to bring its owners a fortune, and with the arrival of DApps, several fortunes at once. Examples of popular DEXs are Uniswap, Curve, Balancer, SushiSwap, DODO, Bancor, and Kyber.

The next altcoin is the Kyber Network Crystal, a multi-chain liquidity hub. It seems that KNC held its own throughout this consolidation phase of the market. When the rest of the market was deflating, it was surging. In the $3.50 to $4 price range, it’s about to reach an extremely hazardous area. As in early 2021, this massive supply zone has already been reduced.

In 2019, investors were introduced to the first wrapped Bitcoin product, WrappedBTC (wBTC). The creation of wBTC by BitGo, Kyber Network, and Ren, formerly known as Republic Protocol was revolutionary in its own right, but wBTC is entirely centralized due to BitGo being the sole custodian for wBTC and this entity, partly owned by Goldman Sachs, has full legal control of all locked Bitcoin wrapped in wBTC.

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].
