const startMoralis = async () => {
await Moralis.begin({
apiKey: course of.env.MORALIS_API_KEY


module.exports.handler = async (occasion) => {
// Get native steadiness
const nativeBalance = await Moralis.EvmApi.steadiness.getNativeBalance({
handle: occasion.handle,
chain: occasion.chain

// Format the native steadiness formatted in ether through the “.ether” getter
const nativeBalanceEther = nativeBalance.outcome.steadiness.ether;

return {
outcome: nativeBalanceEther
}; ”getWalletNfts()” – So as to add this operate, begin by creating a brand new file referred to as ”getWalletNfts.js”: 

Creating the getWalletNfts.js file inside Visual Stuido Code.

You may then open ”serverless.yml” and enter the code beneath into the ”features” part: 

handler: features/getWalletNfts.handler

Lastly, open ”getWalletNfts.js” and add the code from the next snippet: 

‘use strict’;
