CryptoPulse

Inspiration

We wanted to create a simple but powerful crypto dashboard where users can track live prices, charts, and manage alerts in real-time. Many platforms are overloaded or too complex, so we built something lightweight and easy to use.

What it does

CryptoPulse allows users to:

• View live cryptocurrency prices across multiple currencies (USD, EUR, NGN, GBP).
• See interactive charts with different time ranges (24h, 7d, 30d).
• Add coins to a watchlist and export/import them.
• Set alerts when coin prices cross a target value.

How we built it

We used:

• Frontend: React + Vite + Tailwind CSS
  
• Data: Coingecko API
  
• Deployment: Vercel
  We also handled API proxying to bypass CORS issues.

Challenges we ran into

• CORS errors when fetching from the Coingecko API.
  
• Rate limits causing prices to sometimes load slowly.
  
• Debugging deployment issues on Vercel with vercel.json setup.
  

Accomplishments we’re proud of

• Built a working crypto dashboard that updates in real-time.
  
• Learned how to handle API rate limits and deploy on Vercel.
  
• Designed a clean and responsive UI with dark/light modes.
  

What we learned

• How to use Vite with React for fast builds.
  
• How to deploy on Vercel with API integration.
  
• How to improve UI responsiveness for mobile.
  

What’s next for CryptoPulse

• Improve loading speed by caching results.
  
• Add more exchanges beyond Coingecko.
  
• Mobile-first improvements and push notifications for alerts.
