Installing and setting up MetaMask

MetaMask can be downloaded on Chrome and Firefox, or on iOS and Android if you’re a mobile user. For the purposes of this tutorial, we’ll use the Firefox version, but the instructions will be more or less the same for every platform.

Firstly, you’ll want to head over to the MetaMask . From there, select whichever platform you’re using, and follow the steps to install it on your device. Easy!

Next, follow along with the setup specified by the app. Go ahead and click Create a Wallet. Write down the backup somewhere secret (preferably not on an Internet-connected device). Without this phrase, your funds can’t be recovered if your device is damaged or lost. Confirm that you’ve written them down on the next page.

And that’s it! You should now see your wallet, ready to send and receive funds.

Configuring the wallet

Let’s change that. We want to access the Settings to point the wallet towards BNB Smart Chain nodes.

On the Settings page, we want to locate the Networks menu.

We want to click Add Network in the top-right corner to manually add the U2U Network one – it doesn’t come packaged with MetaMask. It’s important to note that there are two networks we can use here: the testnet or the mainnet. Below are the parameters to fill in for each.

Mainnet (This is the one you are probably looking for)

Network Name: U2U Solaris Mainnet

ChainID: 39

Symbol: U2U

Testnet

Network Name: U2U Nebulas Testnet

ChainID: 2484

Symbol: U2U

You might notice straight away that we’re still dealing with an wallet. At best, this won’t work with U2U Network dApps. At worst, you could lose funds by sending them to addresses you can’t actually use.
