Web 3.0 is all set to change our internet habits. But to enable the growth of the Web 3.0 ecosystem, we need to ensure safe and seamless exchanges. And wallets play a key role in this. Ethereum-based wallet MetaMask is particularly popular. However, Metamask can use a little help with handling rush-hour traffic. Enter Arbitrum. In this article we try to explain how the latter works and helps the former scale. All of this and more while you learn how to add Arbitrum to Metamask.
Introduction to Arbitrum
In the early days of Ethereum, the network was relatively slow and inefficient. That made it difficult to use when it came to certain applications. To address this issue, developers began working on what is known as layer-2 scaling solutions. These are essentially tools or platforms on Ethereum that help to make it faster, cheaper, and more efficient. Arbitrum is one such scaling solution for Ethereum.
Arbitrum was developed by a company called Offchain Labs in 2021. The idea behind it was to help Ethereum improve so that it could support more transactions and apps. To achieve this, Arbitrum uses a technology called “optimistic rollups.” Rollups essentially work by bundling/rolling multiple transactions together. The rollups mean that the transactions are processed as one, so the overall efficiency improves and cost reduces.
Arbitrum, therefore, allows developers to build faster and more scalable apps on Ethereum.
Why use Arbitrum?
One of the key benefits of using Arbitrum is that it can help to reduce transaction fees on the Ethereum network. This is because the network can process more transactions per second. Another benefit is that the fees drop because of faster transactions. Arbitrum also adds some security features to the mix.
Currently, there are a number of applications that use Arbitrum. Among them are decentralized finance (DeFi) platforms, gaming applications, and many more. The fact of its popularity also makes Arbitrum advantageous.
Steps to install and set up MetaMask
Arbitrum works well with MetaMask, among various other applications. It helps the wallet navigate Ethereum’s network congestion better. Read this to learn more about MetaMask and its safety features. To add the option of Arbitrum on your MetaMask wallet, you must first set up your wallet. Follow these simple steps to install MetaMask and communicate with the Ethereum ecosystem.
- Visit the MetaMask website to download an extension for your preferred web browser. It is compatible with Google Chrome, Mozilla Firefox, Brave, and Microsoft Edge.
- Once the extension is installed, click on the MetaMask icon in your browser to launch the extension.
- Click the “Get Started” button to begin the setup process.
- Create a new MetaMask wallet and set a strong password. Agree to the terms of service when it prompts you to do so.
- You will be given a seed phrase/recovery phrase. While creating it, you should write it down and set it aside in a safe place. This phrase will help you recover your wallet if you lose access to your MetaMask account.
- After recording your seed phrase, click “Next.”
- The interface will then prompt you to confirm your seed phrase. Reenter it in the correct order when this happens.
- Confirming the seed phrase means your MetaMask wallet is ready to use. You can see your account balance and transaction history now and use it to interact with Ethereum-based decentralized applications (dApps). For instance, you can buy and sell crypto assets on such apps after this.
Adding Arbitrum to MetaMask
Adding Arbitrum to your MetaMask wallet will let you use Ethereum’s dApps and participate in decentralized finance (DeFi). You can integrate Arbitrum with MetaMask by following a few simple steps.
Before starting, please note that you will need some ETH in your MetaMask wallet. This will help pay the transaction fees on Arbitrum.
