🛒 Bitrefill Hackathon – Building Fam-Fi with My Brother

What a pleasure it was to work side-by-side with my brother during the first Bitrefill Virtual Hackathon. Together, we built Fam-Fi, a family-oriented finance app that helps parents reward their children for completing chores—by letting them earn XP and exchange it for real-world gift cards using Bitrefill.

👨‍👩‍👧‍👦 How Fam-Fi Works

Fam-Fi makes financial responsibility fun and collaborative for families. Here's how it works:

• Parents create a family account and share an invite code with their children.
• Chores are assigned to each child, each with an XP value.
• Children complete chores, and XP is awarded after parent approval.
• Parents stock the reward shop with Bitrefill gift cards from their account.
• Children redeem XP for real-world gift cards in the shop.

It’s a fun, gamified way to teach kids the value of effort and reward—while introducing them to modern tools like crypto and e-commerce.

🛠️ Tools We Used

• Next.js – For building the frontend and routing
• Supabase – Realtime database and authentication
• Tailwind CSS – Utility-first styling
• Farcaster – To integrate social identity and make it web3-native
• Bitrefill – For creating the gift card reward system

💡 Reflections

This hackathon wasn’t just a technical challenge—it was a bonding experience. Building something meaningful with my brother and shipping it in just a few days felt incredibly rewarding.

We’re excited to continue working on Fam-Fi and possibly bring it to more families looking to introduce better financial literacy through simple tech and crypto-powered rewards.
