If this sounds thrilling, be a part of us beneath as we kick issues off by diving straight into our overview of constructing dapps on Optimism!
An Overview of Constructing Dapps on Optimism
Optimism launched in 2021, and it’s a number one EVM-compatible ETH layer-2 blockchain. By using optimistic roll-up know-how, Optimism effectively bundles tons of of off-chain operations right into a single Ethereum layer-1 transaction. This strategy considerably enhances Ethereum’s scalability by facilitating faster transactions at a low price, offering a extra environment friendly and cost-effective answer for customers and builders alike!
So, how do you construct decentralized functions (dapps) on Optimism?
Anybody who desires to construct high Optimism dapps wants entry to an Optimism-compatible API. An API – quick for ”utility programming interface” – is a algorithm, protocols, and strategies. Moreover, these mean you can seamlessly work together with a blockchain community to combine Web3 performance and on-chain knowledge into your initiatives. With out APIs, you’ll usually have to arrange the underlying infrastructure for querying the varied blockchain networks your self, which is a tedious and time-consuming activity.
Anybody seeking to carry their dapps to greater than only one community sooner or later must also make certain to make use of cross-chain appropriate APIs. This can make it tremendous simple so that you can develop your initiatives throughout the most important chains, permitting you to achieve a considerably broader consumer base.
However the place do you discover the perfect Optimism API?
Nicely, on the high of the listing of premier Web3 API suppliers, you’ll discover Moralis!

Step 4 – Write a Script Calling the Optimism API
On this part, we’ll present you the best way to name the varied endpoints of Moralis’ Optimism API. To take action, we’ll write a brief script for fetching the native steadiness of a pockets with the getNativeBalance() endpoint. Nonetheless, that is merely an Optimism API instance, and you may comply with roughly the identical process for any of our endpoints!
Earlier than persevering with, ensure you have the next prepared:
From right here, arrange a brand new folder in your IDE and initialize a brand new venture by working the next command in a brand new terminal:
npm init
Subsequent, set up the Moralis SDK with the next terminal command:
npm set up moralis @moralisweb3/common-evm-utils
You then have to open your ”package deal.json” file and add ”sort”: ”module” to the listing:
Subsequent, create a brand new ”index.js” file and add the next code:
import Moralis from ‘moralis’;
attempt {
await Moralis.begin({
apiKey: “YOUR_API_KEY”
});
const response = await Moralis.EvmApi.steadiness.getNativeBalance({
“chain”: “0xa”,
“deal with”: “0xCBA6a2397b322CF1389f6d1adc05F75F36B20116”
});
console.log(response.uncooked);
} catch (e) {
console.error(e);
}
From right here, you now have to configure the code barely by changing YOUR_API_KEY together with your Moralis API key, together with modifying the chain and deal with parameters to suit your question.
That’s it; you’re now able to run the script!
Step 5 – Run the Code
To execute the script, open a brand new terminal and run the command beneath in your venture’s root folder:
node index.js
In return, you’ll get a response that appears one thing like this:
{
“steadiness”: “57881481011270850225”
}
That’s it! You now know the best way to fetch all the things from pockets balances to token costs utilizing Moralis’ Optimism API suite. Consequently, you’re now outfitted with the abilities to fetch on-chain knowledge and might begin to construct your personal dapps on Optimism!
