A step-by-step guide on how to connect Arbitrum to MetaMask. Read more!

Arbitrum is a layer 2 scaling solution designed by Offchain Labs in an effort to make Ethereum more scalable i.e. process faster transactions with lower fees. Since it is a layer-2 solution, it derives most of its security from the underlying Ethereum mainnet.

Arbitrum is one of the largest Layer-2 scaling solutions for Ethereum and has a TVL of $975M at the time of writing.

In this article, we will go through the steps to add the Arbitrum network to MetaMask. Let’s dive in!

Install MetaMask.

You will need to have your MetaMask wallet up and running in your “Extensions” tab on your browser. Download the wallet from the official website and install it. After installation, it will appear in the list of extensions. You can easily pin it to your main screen by clicking the “Pin” button next to the wallet extension in the list. Thus, you will have quick and easy access to it. Once you pin it, it will look like this.

Now, click on the MetaMask icon. By default, the wallet will open as a side frame on your browser. To add a new network to it, you need to open it in “expanded view”. To do this, simply select the “Extended View” option by clicking on the three dots in the upper right corner of your wallet.

Your wallet will then open in a new browser tab.

Go to the disk in the upper right corner and click the “Settings” button.

A new screen will open on the same tab. It will have several options for you to choose from in the left pane. Simply click on the “Networks” tab to add a new network. Once completed, a new screen will appear. Click “Add a network” to add network details.

Add Arbitrum Mainnet to MetaMask

The network details you will need to add to your MetaMask wallet are:


Network name

Stream ID

Currency symbol

Block Explorer

Although “Block Explorer” is listed as optional, it is recommended to include it anyway. You can easily get all this information from the official network documentation. To help make the process efficient for you, I’m also listing the details below.

  • Network Name: Arbitrum One
  • New RPC URL:
  • Series ID: 42161
  • Currency symbol: ETH
  • Block Explorer URL:

After filling these details, your network will be added to the wallet. Now you can copy your wallet address and start transferring funds to and from the wallet!
