npm set up moralis @moralisweb3/common-evm-utils
You then must open your ”bundle.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’;
strive {
await Moralis.begin({
apiKey: “YOUR_API_KEY”
});
const response = await Moralis.EvmApi.steadiness.getNativeBalance({
“chain”: “0xa”,
“handle”: “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 handle 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 under 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 find out how to fetch every little thing from pockets balances to token costs utilizing Moralis’ Optimism API suite. Consequently, you’re now geared up with the abilities to fetch on-chain information and may begin to construct your personal dapps on Optimism!
