Step 2: Easy methods to Construct Arbitrum Initiatives – Add Your Moralis API Key and Configure the Code
When you have not already, the very first thing you could do from right here is to enroll with Moralis. You may create your account without spending a dime, which solely takes a couple of seconds. With an account at hand, you could fetch your API key. To take action, log in to the Moralis admin panel, navigate to the ”Web3 APIs” tab, and click on on the copy button:
Subsequent, return to your code editor, find the ”.env.instance” file within the ”backend” folder, and rename it ”.env”. From there, open the file and set MORALIS_API_KEY to equal your key. It ought to look one thing like this:
MORALIS_API_KEY = “JnJn0MWxFNPv4V1PZQY19GH…”
Additionally, as we confirmed in the course of the software demo, the unique template solely options the Ethereum and Polygon networks. Consequently, you could make a couple of configurations so as to add the Arbitrum testnet your self. As a consequence of time limitations, we will be unable to cowl all of the required configurations. Nevertheless, we are going to present an instance that you should utilize for reference.
For example, for the /nativeBalance route within the backend folder’s ”index.js” file, the chain is fetched from the app’s UI. Following this, an if assertion checks the chain ID to have the ability to fetch the worth in USD, and it appears one thing like this:
let nativeCurrency;
if (chain === “0x1”) {
nativeCurrency = “0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2”;
} else if (chain === “0x89”) {
nativeCurrency = “0x0d500B1d8E8eF31E21C99d1Db9A6444d3ADf1270”;
}
Because you wish to make it appropriate for the Arbitrum testnet, add the testnet’s chain ID as one other else if assertion in the identical method as the opposite choices. You need to additionally add Arbitrum as an choice to the ”frontendUI/src/elements/WalletInputs.js” file. Initially, it solely appears like this:
Proceed to observe an identical sample all through the code so as to add the Arbitrum testnet in all of the required locations. When you want additional assist with this, please watch and observe alongside within the video beneath.

What’s the Arbitrum Testnet?
Arbitrum is Offchain Labs’ brainchild, and the mainnet launched two years in the past in 2021. The community is a layer-2 (L2) platform with the aim of fixing essential scalability problems with the Ethereum community!
Arbitrum is Ethereum Digital Machine-compatible (EVM). As such, the community has the aptitude of working unmodified Ethereum good contracts. Moreover, the community leverages a way referred to as ”transaction rollups”, which is a method the place a bunch of transactions is recorded on a layer-1 (L1) community and executed on a scalable layer-2 platform like Arbitrum.
As with all blockchain networks, transactions on the Arbitrum platform require gasoline charges. Consequently, when creating Arbitrum-compatible purposes, builders typically make the most of a testnet. This permits them to attempt their tasks safely and securely earlier than committing to a mainnet. Within the case of Arbitrum, the primary testnet is named the ”Arbitrum Goerli testnet”. Furthermore, the Arbitrum Goerli testnet relies on Goerli, which, together with the Sepolia testnet, is one in all Ethereum’s most distinguished testnets. The Arbitrum Goerli testnet is absolutely EVM-compatible. Therefore, it helps Ethereum-based contracts and property. Testers and builders principally use this community to debug and check out their Arbitrum purposes.
Nevertheless, despite the fact that it is a testnet, builders nonetheless have to pay for his or her transactions on the Arbitrum testnet. Luckily, it’s doable to make use of a crypto faucet to accumulate free Arbitrum testnet tokens. To be taught extra about this, take a look at our information on the most effective Arbitrum faucet!
