Real-time Token Data in Your App: The Fastest Way to Get There

Fetch and display Wallet Token Balances using Moralis API

Adding blockchain features to an application does not mean you have to learn a new set of terms or pick up a new programming language. If all you need is to show wallet balances and token data, you can treat blockchain like any other data source and access it through an API, using the tools you already work with.

That is exactly what this tutorial focuses on. There is no deep dive into protocols or infrastructure. The goal is simple: fetch real-time token data and display it in a clean, predictable way.

If you are already comfortable with JavaScript, you can start pulling live token data today without adding extra complexity to your setup.

Why Build Everything from Scratch?

You can absolutely connect directly to blockchain nodes and pull raw data yourself. The real work starts after that. On-chain data is messy, inconsistent, and rarely usable as-is. Turning it into something you can actually display means writing extra logic, handling edge cases, and maintaining that code over time.

Instead of building and maintaining that entire layer yourself, this approach relies on a specialized data API that handles all of that for you. What you get back is structured, ready-to-use data that fits naturally into a Node.js or Frontend workflow.

This keeps your attention where it matters: building features, not plumbing.

Implementation

The setup is intentionally lightweight. There are no smart contracts involved and no custom infrastructure to manage.

All you need is an API key and a few lines of JavaScript.

  // Initialize and fetch token data
  await Moralis.start({
    apiKey: "YOUR_API_KEY"
  });
    
  const response = await Moralis.EvmApi.token.getWalletTokenBalances({
    address: "0x...",
    chain: "0x1"
  });
 

  // Initialize and fetch token data
  await Moralis.start({
    apiKey: "YOUR_API_KEY"
  });
    
  const response = await Moralis.EvmApi.token.getWalletTokenBalances({
    address: "0x...",
    chain: "0x1"
  });
 

This call returns wallet token balances along with token names, symbols, decimals, and their USD values. In other words, everything you need to ship a working feature quickly, without extra data wrangling.

Video Tutorial

In a short, 2.5-minute video, I walk through the code step by step.
I explain what the endpoint does, how the API call is structured, and how wallet token balances and their USD values show up directly in the console.

Conclusion

When you treat blockchain as a data source instead of an infrastructure problem, development becomes much more straightforward. You stay inside a familiar environment, while the heavy lifting happens behind the scenes.
