You have probably spent time checking token prices, refreshing charts, and wondering whether you missed a move. Along the way, you may have thought: “I wish there were a simple app that showed exactly what I care about.”
That is a good place to start building. With an AI coding assistant, you can describe a small tool in everyday language and ask it to create a first version. People often call this vibe coding. You explain the idea, try the result, and ask for changes. You still need to check whether it works, but you can begin without knowing how to write the code yourself.
Your first project could be something familiar: a crypto watchlist.
Start with a problem you already understand
Imagine a page showing three coins you follow. Each has a price, its change over the last 24 hours, and the time the price was last updated. No crowded screen or endless tabs—just the information you came to see.
That is a useful first project because you already know what the result should look like. You can spot a missing price, an unreadable number, or a button that does nothing. Keeping the project small also makes it easier to explain what needs fixing.
Open an AI coding tool and give it a clear request like this:
Build a simple crypto watchlist website for a beginner. Show Bitcoin, Ethereum, and Solana, with a price and 24-hour percentage change for each. Start with made-up example prices and clearly label them “Demo data.” Add a refresh button and a last-updated time. Make it easy to read on a phone. Do not add wallet connections or trading. Explain how I can open and test it.
The first version might need work. That is normal. You can ask for bigger numbers, fewer colours, or a clearer layout, just as you would explain changes to someone helping you design a page.
Make it work before making it live
Starting with example prices lets you focus on the basics. Can you open the page? Is the text readable? Do the buttons behave as expected? A working layout is easier to improve than a complicated app with several things going wrong at once.
Once you are happy with it, ask the assistant to connect a suitable price-data service. These services let apps request market information through an API—think of it as a doorway through which your app asks, “What is the latest price?”
A useful follow-up request is: “Explain which data service you recommend, whether it costs money, and how often it allows updates. Show a clear message if the price cannot be loaded.” Some services require an account or a secret access key, so ask the assistant how to keep that key out of publicly visible code.
Check the numbers, not just the appearance
A polished screen can still show incorrect information. Compare your watchlist with the data provider’s own figures, checking that the currency and timestamps match. For smaller tokens, verify the token’s address and network too: different coins can share the same name.
Try refreshing the page and disconnecting your internet. Does the app explain that its prices are old, or does it make them look current? Ask the assistant to help investigate anything confusing, but verify the result yourself.
You now have something useful that you helped create. After using it for a few days, you will probably discover the best next feature: perhaps a target price, a personal note beside each coin, or a comparison with the price when you first added it. Start with the one you actually need, and build from there.
