MetaMask Tutorial: Step Analysis of Integrating Arbitrum into MetaMask

MetaMask is a cryptocurrency wallet connected to the Ethereum mainnet by default. You can find the plug-in and mobile app on the official MetaMask website.

If you want to connect to a network such as Arbitrum, you need to add some blockchain information in MetaMask, including chain ID, custom RPC URL and network name. If you want to add Arbitrum tokens, you also need to import the correct token address.

Adding newly created blockchains to MetaMask is a transferable skill suitable for adding Ethereum Virtual Machine networks such as Binance Coin Smart Chain and Polygon.

Introduction

To use the Arbitrum blockchain, you need to prepare a compatible cryptocurrency wallet in advance, such as MetaMask. However, MetaMask does not automatically add Arbitrum as a blockchain option by default. However, the steps to bind your wallet with Arbitrum are very simple and can be completed quickly.

Installation and setup of MetaMask

1. Download through the MetaMask website and install MetaMask on Chrome, iOS or Android devices. In order to ensure that the download is genuine, please double-check that you are visiting the official MetaMask website.

2. After downloading and installing the plug-in, click [Start] on the MetaMask welcome page.

#3. If you are a new wallet user, please click [Create Wallet]. If you already have a wallet, you can use the [Import Wallet] option to import the existing wallet using a mnemonic phrase.

4.MetaMask will ask you if you are willing to share anonymous usage data to help improve the plugin. Accepting or rejecting will not affect your MetaMask experience.

5. Create a secure password. This operation will be used to log in to the wallet. Please note that the password is not your mnemonic phrase. The password prevents someone from using the wallet through your device. If you forget your password, you can use your password via a mnemonic phrase.

# 6. After creating your password, MetaMask will provide you with important information about your mnemonic phrase. If you are new to cryptocurrency wallets, be sure to read this section completely and watch the video tutorial before proceeding.

#7. Click the lock to receive a 12-word mnemonic phrase. Write the mnemonic phrase in the correct order and store it in a safe location (preferably offline). Please do not share your mnemonic phrase with others. A mnemonic phrase is the ultimate backup for your account if you lose access. Click [Next] to continue.

# 8. Confirm your mnemonic phrase by selecting the words at the bottom of the screen in the correct order. Click [Confirm] when completed.

9. You have completed the setup of MetaMask wallet. Click [Complete All] to start using your wallet.

#10. Click the puzzle icon in the Chrome browser to pin MetaMask to the toolbar for convenient use. MetaMask is only associated with Ethereum by default. In the following chapters you will learn how to connect MetaMask to Fantom.

Configure wallet

1. If you add Arbitrum functionality to your wallet, you need to add some simple network details in Metamask. First, open Metamask and click on the Network drop-down menu.

2. Now, click [Add Network] in the pop-up window.

3. You need to add the following details to the [Add Network] page that opens. When finished, click [Save].

Network Name	Arbitrum One
##New RPC URL	https://arb1.arbitrum.io/rpc
Chain ID	42161
Currency Contract	ETH
Block explorer URL	https://arbiscan.io/

4. Now you will successfully connect to the Arbitrum network.

Add Arbitrum tokens to MetaMask

You need to add them manually in order for Arbitrum tokens to appear on the wallet user interface (UI). Please note that your wallet will still receive unimported tokens, but they will not show up themselves.

1. First, go to Arbiscan and find the token contract and token details you want to add. If the token is not on Arbiscan, please obtain the contract address from the project official website. You must always beware of false contracts created by criminals.

2. Return to MetaMask and click [Import Tokens].

#3. Paste the token contract address and MetaMask will fill in the remaining details. If not, add it manually. Please click [Add Custom Token] to complete.

#4. Click [Import Tokens].

#5. Your wallet will now display the balance of the tokens you just added.

Summary

After setting up the Arbitrum mainnet in MetaMask, you can start sending cryptocurrency, collecting NFTs and using DeFiDApp smart contracts for free. You can even exchange tokens within the plugin. However, in order to cover transaction costs, make sure you have Ethereum in your wallet. By using the Arbitrum Bridge, you can obtain ether from the Ethereum mainnet.

MetaMask is not exclusive to Ethereum and Arbitrum. The wallet actually also supports the entire Ethereum Virtual Machine (EVM) ecosystem, including the Binance Coin Smart Chain. Armed with the skills in this tutorial, you can now add more chains and use them with the correct details.
