const Moralis = require(‘moralis’).default;

Following this, it’s essential to initialize Moralis with the Web3 API key specified earlier. As such, enter the next snippet beneath the Moralis necessities: 

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

startMoralis();

Lastly, the very last thing it’s essential do is substitute the entire ”module.exports.handler” part with the code beneath. In doing so, you’ll implement the correct SDK technique: 

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

// Format the native steadiness formatted in ether by way of the .ether getter
const nativeBalanceEther = nativeBalance.outcome.steadiness.ether;

return {
outcome: nativeBalanceEther
}
};

‘use strict’;
const Moralis = require(‘moralis’).default;

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

startMoralis();

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

// Format the native steadiness formatted in ether by way of the .ether getter
const nativeBalanceEther = nativeBalance.outcome.steadiness.ether;

return {
outcome: nativeBalanceEther
}
};

The “getWalletNfts()“ Operate 

The following perform we’ll add is ”getWalletNfts()”, and we will observe the identical steps because the preliminary perform. Nonetheless, since we beforehand used the ”handler.js” file, it’s essential create a brand new one from scratch. As such, go forward and create a brand new file within the ”features” folder known as ”getWalletNfts.js”: 

Subsequent up, open ”serverless.yml” and add the perform to the ”features” part: 

Lastly, to high issues off, add the next code to the ”getWalletNfts.js” file: 

‘use strict’;
const Moralis = require(‘moralis’).default;

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

startMoralis();

module.exports.handler = async (occasion) => {
// Get pockets NFTs
const nfts = await Moralis.EvmApi.nft.getWalletNFTs({
deal with: occasion.deal with,
chain: occasion.chain,
restrict: 10
});

return {
outcome: JSON.stringify(nfts)
}
};

That’s it for the ”getWalletNfts()” perform! All that continues to be is testing and deploying the features to Lambda, and we’ll present you the way to take action within the following part!
