How to Add Arbitrum to MetaMask

İçindekiler

Arbitrum is a layer 2 scaling solution that has been designed by Offchain Labs in an attempt to make Ethereum more scalable i.e., process faster transactions at low fees. Since it’s 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 be going through the steps to add the Arbitrum network to MetaMask. Let’s dive in!

Install MetaMask

You’ll need 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’s extension in the list. This way, you’ll 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’ll need to open it in “Expanded View”. To do that, simply select the “Expanded View” option by clicking the three dots at the top-right corner of your wallet.

Your wallet will then open in a new browser tab.

Head over to the disc at the top-right corner and click on the “Settings” button.

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

Add Arbitrum Mainnet to MetaMask

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

RPC URL

Network Name

Chain ID

Currency Symbol

Block Explorer

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

Network Name: Arbitrum One
Chain ID: 42161
Currency Symbol: ETH
Block Explorer URL: https://arbiscan.io/

Once you have filled in these details, your network will be added to the wallet. You can now copy your wallet address and start transferring funds to and from the wallet!
