Understanding Account Abstraction: How to Get Native Balances from Smart Accounts

There are two primary account types:

• Contract Accounts
• Token Accounts

Token Accounts provide users direct control over their tokens via private keys, enabling transactions and interaction with dApps.

Contract Accounts function autonomously, controlled by pre-defined smart contract code without private keys.

tip

As an example of account types, you can read the Ethereum Accounts article.

Now, let's explore how Moralis simplifies the process of getting the native balance of a smart contract account.

This step-by-step tutorial shows how to retrieve the native balance from a smart account, simplifying the process and offering code examples in multiple programming languages.

Step 1: Setup Moralis

Read the article Setting Up Moralis: Getting Started and make sure to finish all the steps. Only after that you can go ahead to complete this guide.

Step 2: Get the Native Balance of a Smart Account

You can use the API endpoint getNativeBalance to get the native balance for a specific wallet address. You will need two essential parameters:

• address
• chain

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

index.js (JavaScript)

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

// Define an asynchronous function runApp to retrieve the native balance of a smart contract account
const runApp = async() => {
  // Initialize the Moralis SDK with your API key and other configurations
  await Moralis.start({
    apiKey: "YOUR_API_KEY",
    // ...add any other relevant configuration options
  });

  // Define the address of a smart contract account for which you want to fetch the native balance
  const address = "0x350845DD3f03F1355233a3A7CEBC24b5aAD05eC5";

  // Specify the blockchain that you are working with (e.g., Ethereum)
  const chain = EvmChain.ETHEREUM;

  // Use the Moralis getNativeBalance method to request the native balance
  const response = await Moralis.EvmApi.balance.getNativeBalance({
    address,
    chain,
  });

  // Log the JSON response containing the native balance to the console
  console.log(response.toJSON());
}

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

index.ts (TypeScript)

// Import the Moralis library and necessary modules
import Moralis from "moralis";
import { EvmChain } from "@moralisweb3/common-evm-utils";

// Define an asynchronous function runApp to retrieve the native balance of a smart contract account
const runApp = async () => {
  // Initialize the Moralis SDK with your API key and other configurations
  await Moralis.start({
    apiKey: "YOUR_API_KEY",
    // ...and any other configuration options
  });

  // Define the address of a smart contract account for which you want to fetch the native balance
  const address = "0x350845DD3f03F1355233a3A7CEBC24b5aAD05eC5";

  // Specify the blockchain that you are working with (e.g., Ethereum)
  const chain = EvmChain.ETHEREUM;

  // Use the Moralis getNativeBalance method to request the native balance
  const response = await Moralis.EvmApi.balance.getNativeBalance({
    address,
    chain,
  });

  // Log the response as a JSON object, which contains the native balance information
  console.log(response.toJSON());
};

// Execute the runApp function to start the process
runApp();

index.py (Python)

# Import the necessary modules from the Moralis library
from moralis import evm_api

# Replace "YOUR_API_KEY" with your actual API key
api_key = "YOUR_API_KEY"

# Define the parameters required for fetching the native balance
params = {
    # Replace with the target address of smart contract account
    "address": "0x350845DD3f03F1355233a3A7CEBC24b5aAD05eC5",

    # Specify the blockchain you are working with (e.g., Ethereum)
    "chain": "eth",
}

# Use the Moralis get_native_balance method to retrieve the native balance
result = evm_api.balance.get_native_balance(
    api_key=api_key,
    params=params,
)

# Print the result, which contains the native balance information
print(result)

Step 3: Run the Script

To run the script, enter the following command:

Shell (JavaScript)

node index.js

Shell (TypeScript)

ts-node index.ts

Shell (Python)

python index.py

In your terminal, you should see the following JSON response:

[
  {
    "balance": "3989233490541891348056490"
  }
]

Congratulations 🥳! You have successfully retrieved the native balance of a smart account using the Moralis Wallet API.
