How to get the native balance of an ERC20 token vault

Prerequisites​

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

  • Node v.14+ or Python
  • NPM/Yarn 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 the Moralis SDK in your project.

npm install moralis @moralisweb3/common-evm-utils

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 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();

Step 3: Run the script​

To run the script, enter the following command:

node index.js

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

[
{
"balance": "3989233490541891348056490"
}
]

Congratulations πŸ₯³ You just got the native balance of an ERC20 token vault with just a few lines of code using the Moralis Wallet API!
