Wallet Setup for Arbitrum Compatibility

Even though you can use other wallets, Metamask is the one we recommend. Throughout this guide, we will assume that you are using the Metamask wallet since it is the one most people use, the process of setting up a wallet should be very similar regardless of the wallet you choose.
It's worth mentioning that Nitro network settings are the same as Arbitrum One's previous settings.
The easiest way to add Arbitrum to your wallet is through Chainlist. Using the steps below, you can add Arbitrum to your wallet without typing anything manually.
