# Arbitrum NETWORK Setup

**Step 1: Add a wallet.**&#x20;

If you don't have a decentralized wallet yet, we'd recommend MetaMask: [https://metamask.io/download/](https://metamask.io/download/)

If you have MetaMask installed on your devices already, you can add ARB to MetaMask automatically through ARBiscan or manually through MetaMask.&#x20;

**Step 2: Add ARB to MetaMask.**&#x20;

In this tutorial, we will show how to manually add ARB to MetaMask via the MetaMask browser extension and ARB address.&#x20;

1. Open MetaMask Browser Extension. Open the MetaMask browser extension by pressing the MetaMask icon on the top right-hand side of your screen.
2. Add Network. After logging in to your MetaMask account, visit the network selection menu which reads "Ethereum Mainnet" on the upper right side of your screen.&#x20;
3. Click "Ethereum Mainnet" and click on the "Add Network" tab to proceed to the next step.&#x20;

**Step 3:** **Enter ARB Details.**

After clicking on the "Add Network" tab, a new page will be coming up. Enter the required information to proceed.&#x20;

* Network Name – Arbitrum One
* New RPC URL - [https://arb1.arbitrum.io/rpc](https://arb1.arbitrum.io/rpc)&#x20;
* Chain ID – 42161
* Currency Symbol – ETH
* Block Explorer URL [https://arbiscan.io/](https://arbiscan.io/)&#x20;

Then click the "Save" button. So far you have connected to the ARB Mainnet with your MetaMask.&#x20;

**Step 4: Add Funds to Your Wallet.**

Once you've successfully set up the BSC network on your MetaMask Wallet, you can transfer BNB or other assets to your MetaMask wallet.&#x20;
