Now, if you’re already familiar with the Arbitrum network and want to get right into it, feel free to skip straight into the ”How to Claim Arbitrum Sepolia Testnet Funds in 3 Steps” section! 

Otherwise, follow along as we start by answering the question, “What is Arbitrum?”.

What is Arbitrum? 

Arbitrum is an Ethereum layer-2 (L2) platform, and the mainnet officially launched in 2021. It’s the brainchild of Offchain Labs, and it was initially introduced to address some of the shortcomings of Ethereum, such as the critical scalability issues the network has been experiencing over the past few years.

Title and Logo - What is Arbitrum?

Arbitrum is fully EVM-compatible, and it’s designed to allow you to seamlessly run unmodified Ethereum smart contracts on the network. Moreover, the Arbitrum network increases the capabilities of Ethereum smart contracts by improving speed, scalability, and execution costs.

Arbitrum is able to improve speed, scalability, and lower transaction costs through a technique called ”optimistic rollups”. With this method, Arbitrum executes transactions off-chain before they are bundled into large batches that are submitted to the Ethereum mainnet. In doing so, Arbitrum can process more transactions faster while at the same time leveraging the excellent security of the Ethereum mainnet. 

With a brief overview of Arbitrum, let’s take the following section to explore some of the main advantages of the network! 

What are the Advantages of Arbitrum? 

The Arbitrum network has many benefits and advantages, and in this section, we’ll cover three prominent examples: 

  • EVM-Compatability: The Arbitrum L2 network is EVM-compatible at the byte-code level. This means it’s possible to run Ethereum smart contracts on the network without any modifications. Consequently, when working with Arbitrum, you can use many of the tools used for Ethereum development. 
  • Fast Transactions, Low Fees: Through the method of optimistic rollups, Arbitrum is able to offer faster transactions and lower fees. This makes Arbitrum a more economically friendly alternative compared to working directly on the Ethereum mainnet.
  • Existing Ecosystem: The Arbitrum network already hosts a vast ecosystem of dapps. One benefit of this is that you can interact with and learn from a big community of like-minded developers. 

What is the Arbitrum Sepolia Testnet? 

Arbitrum Sepolia is the testnet for Arbitrum, and it’s a blockchain that mirrors the network’s mainnet. Furthermore, it’s linked to the Sepolia testnet, meaning that it offers you and other developers a secure platform to test and evaluate smart contracts before deploying them to the Arbitrum mainnet.

Here are the details of the Arbitrum Sepolia testnet: 

Arbitrum Sepolia Testnet
Network NameArbitrum Sepolia
New RPC URLhttps://sepolia-rollup.arbitrum.io/rpc
Chain ID421614
Currency SymbolSepoliaETH
Block Explorer URL (Optional) https://sepolia.arbiscan.io/

So, why should you be using the Arbitrum Sepolia testnet? 

Any transaction on a blockchain like Arbitrum requires you to pay a network fee. Consequently, when testing your smart contracts and dapps, doing it directly on the Arbitrum mainnet doesn’t make sense. Fortunately, this is where Arbitrum Sepolia takes the stage! 

Since the Arbitrum Sepolia testnet provides an identical copy of the mainnet, you can test your projects without committing any real-world assets. However, you still have to pay for transactions on the Arbitrum Sepolia testnet as well. Fortunately, you can acquire testnet tokens entirely for free using an Arbitrum Sepolia faucet!

But what is an Arbitrum Sepolia faucet?  

What is an Arbitrum Sepolia Faucet? 

Crypto faucets are websites or applications that dispense a small amount of testnet tokens to users for free. And this is precisely what an Arbitrum Sepolia faucet does for the Arbitrum Sepolia testnet! 

So, how does a crypto faucet work? 

While different types of Arbitrum Sepolia faucets work in various ways, the best ones typically feature simple UIs where you just need to input your Web3 wallet address and click on a button. In return, the Arbitrum Sepolia faucet sends a small, fixed amount of testnet tokens to your wallet.

From there, you can use the tokens to pay for transactions on the Arbitrum Sepolia testnet when trying out your smart contracts and dapps! 

Now, where do you find the best Arbitrum Sepolia faucet?

Where Can You Find the Best Arbitrum Sepolia Faucet? 

Finding the best testnet faucets is easier said than done, and there are a lot of bad actors abusing faucets to gain access to wallet credentials. Furthermore, many free faucets require tweet verifications and sign-up nonsense, which can quickly become a hassle when developing dapps. 

Fortunately for you, this is precisely why we set out to create the Moralis testnet faucets page!

How to Claim Arbitrum Sepolia Testnet Funds in 3 Steps 

In the following sections, we’re going to show you how to claim Arbitrum Sepolia testnet funds in three steps using a crypto faucet:

  1. Get a Web3 Wallet
  2. Add the Arbitrum Sepolia Testnet
  3. Claim Funds Using an Arbitrum Sepolia Faucet

For this tutorial, we’ll be using MetaMask. However, if you prefer another wallet provider, you can follow pretty much the same steps, as the process only differs slightly on occasion. 

Also, the initial step of the tutorial revolves around downloading and setting up MetaMask. Consequently, if you already have a wallet, feel free to skip the first step and jump straight into the second one.

Nevertheless, let’s get going and immediately jump into the first step of this tutorial! 

Step 1: Get a Web3 Wallet 

To kick things off, head on over to ”metamask.io” and click on the ”Download” button to the left to download MetaMask:

At this point, you have two options: create a new wallet or import an existing one. Nevertheless, no matter if you create or import a wallet, once you complete the process, you should find yourself on a page looking similar to the one below:

That’s it; you now have a MetaMask account and are ready to jump into the second step! 

Step 2: Add the Arbitrum Sepolia Testnet 

For the second step, add the Arbitrum Sepolia testnet to your MetaMask wallet. To do so, you can start by clicking on the drop-down menu at the top left, followed by ”Add network”: 

Add Network Button on the MetaMask Module

From there, you can scroll down and click on ”Add a network manually” at the bottom of the page:

Adding new network manually in metamask

This will take you to the page below, where you need to input the network information for the Arbitrum Sepolia testnet:
