If you'd like examples of account types, read the Ethereum Accounts article.

When you're working with ERC-20 tokens, it can be beneficial to track and analyze token transfers associated with a specific contract address. The Wallet API offers a convenient solution to retrieve all the transfers of an ERC-20 token efficiently.

This step-by-step tutorial shows how to track, retrieve, and query an ERC-20 token in a smart account using the account address and the token contract, simplifying the process and offering code examples in multiple programming languages.

tip

This tutorial uses Moralis' getWalletTokenTransfers RPC method.

Step 1: Set Up Moralis​

Please read our Setting Up Moralis: Getting Started article and finish all of its steps. Only after that can you go ahead and complete this guide.

Step 2: Method to Get and Retrieve ERC-20 Transfers for a Given Smart Account Address​

You can use the getWalletTokenTransfers API endpoint to get all transactions from a specific address of a smart account. Moreover, this endpoint allows you to fetch transactions for a given address of a smart account.

You will need two essential parameters:

  • address
  • chain

Once you have obtained both address and chain, you can use the code snippets below to retrieve the transactions:

// Import the required libraries and modules
const Moralis = require("moralis").default;
const { EvmChain } = require("@moralisweb3/common-evm-utils");

// Define an asynchronous function to run the application
const runApp = async () => {
  // Initialize Moralis with your API key and any other required configurations
  await Moralis.start({
    apiKey: "YOUR_API_KEY",
    // ...other configuration options
  });

  // Define the smart account address you want to retrieve ERC-20 transfers for
  const address = "0x9b722B2aA4Cc119aCf8c95bBF5244092Be6880b9";

  // Specify the chain you want to interact with (Polygon in this case)
  const chain = EvmChain.POLYGON;

  // Use Moralis' EvmApi to get wallet token transfers for the specified address and chain
  const response = await Moralis.EvmApi.token.getWalletTokenTransfers({
    address,
    chain,
  });

  // Log the response data to the console in JSON format
  console.log(response.toJSON());
};

// Invoke the runApp function to start the application
runApp();

Step 3: Run the Script​

To run the script, enter the following command:

node index.js
