Lastly, to high issues off, we’ll additionally listing among the main platforms on Optimism to present you some inspiration for what you possibly can construct sooner or later.
If this sounds thrilling, be 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 lots 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 value, 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 help you seamlessly work together with a blockchain community to combine Web3 performance and on-chain knowledge into your initiatives. With out APIs, you’ll usually must arrange the underlying infrastructure for querying the assorted blockchain networks your self, which is a tedious and time-consuming process.
Anybody trying to carry their dapps to greater than only one community sooner or later also needs to be sure that to make use of cross-chain appropriate APIs. This can make it tremendous simple so that you can develop your initiatives throughout the largest chains, permitting you to achieve a considerably broader person base.
However the place do you discover one of the best Optimism API?
Effectively, on the high of the listing of premier Web3 API suppliers, you’ll discover Moralis!
Moralis’ Web3 APIs supply industry-leading response instances and help you cut back the typical time to marketplace for all of your blockchain initiatives by a staggering 83%.

}); getNFTOwners() – Fetch the NFT homeowners for a given contract: const response = await Moralis.EvmApi.nft.getNFTOwners({
“chain”: “0xa”,
“deal with”: “0xB8Df6Cc3050cC02F967Db1eE48330bA23276A492”
});
To discover this instrument additional, please take a look at our official NFT API web page!
Pockets API
The Pockets API is the final word answer for pockets builders and anybody trying to combine pockets performance into their Optimism initiatives. This API helps over 500 million addresses throughout the most well-liked chains. This contains Ethereum, Polygon, BNB Good Chain (BSC), Optimism, and others!
With the Pockets API, you possibly can seamlessly get the native stability, NFT stability, token transfers, profile knowledge, and way more of any pockets deal with. As such, this industry-leading API offers you the whole lot it’s essential to construct pockets dapps on Optimism.
Listed below are three distinguished endpoints to spotlight the ability of the Pockets API:
getNativeBalance() – Fetch the native stability of any pockets: const response = await Moralis.EvmApi.stability.getNativeBalance({
“chain”: “0xa”,
“deal with”: “0x2a82ae142b2e62cb7d10b55e323acb1cab663a26”

Step 4 – Write a Script Calling the Optimism API
On this part, we’ll present you name the assorted endpoints of Moralis’ Optimism API. To take action, we’ll write a brief script for fetching the native stability of a pockets with the getNativeBalance() endpoint. Nonetheless, that is merely an Optimism API instance, and you’ll observe 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 must 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.stability.getNativeBalance({
“chain”: “0xa”,
“deal with”: “0xCBA6a2397b322CF1389f6d1adc05F75F36B20116”
});
console.log(response.uncooked);
} catch (e) {
console.error(e);
}
From right here, you now must configure the code barely by changing YOUR_API_KEY along 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:
{
“stability”: “57881481011270850225”
}
That’s it! You now know fetch the whole lot from pockets balances to token costs utilizing Moralis’ Optimism API suite. Consequently, you’re now geared up with the abilities to fetch on-chain knowledge and may begin to construct your personal dapps on Optimism!
