Code Walkthrough

Create a brand new index.js script and first import Moralis and its EVM utils with these two traces of code:

const Moralis = require("moralis").default;
const { EvmChain } = require("@moralisweb3/common-evm-utils");

Subsequent, you should make sure that your script begins Moralis utilizing your Web3 API key. To that finish, use the next traces of code and ensure to exchange the YOUR_API_KEY placeholder along with your precise API key:

const runApp = async () => {
  await Moralis.begin({
    apiKey: "YOUR_API_KEY",
    // ...and every other configuration
  });

Staying inside the above-defined runApp async operate, outline the handle and chain parameters:

const handle = "0xd8da6bf26964af9d7eed9e03e53415d37aa96045";

const chain = EvmChain.ETHEREUM;

Word: Ensure that to exchange the above handle with an handle you may management and in addition check it correctly. So far as chain goes, you may goal every other supported chain by changing ETHEREUM accordingly. 

Contained in the runApp operate, it’s time to implement the road of code from the introduction. You additionally wish to log the response. Plus, don’t forget to shut the operate:

  const response = await Moralis.EvmApi.transaction.getWalletTransactions({
    handle,
    chain,
  });

  console.log(response.toJSON());
};

runApp();

So, methods to get EVM transactional historical past? Merely use this script (the above traces put collectively):

const Moralis = require("moralis").default;
const { EvmChain } = require("@moralisweb3/common-evm-utils");
