How to get the native balance of an ERC20 token vault

Learn how to get the native balance of a ERC20 token vault using the Moralis Balance API.

Prerequisites

Before getting started, make sure you have the following ready:

  • Node v.14+ or Python
  • NPM/Yarn/PNPM or Pip

Step 1: Setup Moralis

First register your Moralis account and get your Moralis API Key.

Once you have your Moralis API Key, install Moralis SDK in your project.

npm install moralis @moralisweb3/common-evm-utils
yarn add moralis @moralisweb3/common-evm-utils
pnpm add moralis @moralisweb3/common-evm-utils
pip install moralis

Step 2: Get the native balance of an address

In order to get the native balance of an ERC20 token vault, Moralis provides you the [getNativeBalance](https://docs.moralis.io/reference/getnativebalance) API endpoint.

Here you'll need two parameters: address and chain.

Once you have obtained both the address and chain, you can copy the following code:

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

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

  // address of ERC20 token vault, e.g. WETH token address
  const address = '0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2';

  const chain = EvmChain.ETHEREUM;

  const response = await Moralis.EvmApi.balance.getNativeBalance({
    address,
    chain,
  });

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

runApp();
import Moralis from "moralis";
import { EvmChain } from "@moralisweb3/common-evm-utils";

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

  // address of ERC20 token vault, e.g. WETH token address
  const address = '0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2';

  const chain = EvmChain.ETHEREUM;

  const response = await Moralis.EvmApi.balance.getNativeBalance({
    address,
    chain,
  });

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

runApp();
from moralis import evm_api

api_key = "YOUR_API_KEY"

params = {
    # address of ERC20 token vault, e.g. WETH token address
    "address": "0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2", 
    "chain": "eth", 
}

result = evm_api.balance.get_native_balance(
    api_key=api_key,
    params=params,
)

print(result)

To execute the program, run the following command:

node index.js
node index.ts
python index.py

In your terminal, you should see the following response:

[
  {
    "balance": "3989233490541891348056490"
    }
]

Congratulations 🥳 You just got the native balance of an ERC20 token vault with just a few lines of code using the Moralis Balance API!
