A
@farcaster_xyz quiz where users pay gas fees (~$0.01) to unlock and save their score on the blockchain.
Built in 2 days with no blockchain experience.
Breakdown 🧵👇
I'm a junior backend dev (Java/Spring Boot) with no Web3 experience.
Joined Base's "Build on Base" program for rewards and potential airdrops 💰.
Built a Farcaster mini app to:
- Learn Web3
- Create something cool
- Position for future drops
Concept:
5 Farcaster questions → Pay gas fee → Score saved on Base blockchain.
Users get:
✅ Instant results
✅ On-chain score proof
✅ Shareable on Warpcast
Tech Stack:
Frontend:
- React TypeScript Vite
- Wagmi for wallet connections
- OnchainKit by
@Coinbase
- React Hot Toast for notifications
Backend:
- Solidity smart contract
- Hardhat for deployment
- Base mainnet (chain ID: 8453)
Deployed on Vercel 🚀
Cost Breakdown:
- Smart contract deployment: ~$3
- Base Sepolia testing: $0 (free testnet)
- Vercel hosting: $0 (free tier)
- Domain: $0 (Vercel subdomain)
- OnchainKit API: $0 (free)
Total: $3 to launch a dApp 🤯
It's that simple to launch a mini app.
Final Thoughts:
As my first on-chain mini app, I'll build more and keep evolving.
Thanks
@Zun2025 for insights.
Web3 development is more accessible than I thought. If you know JavaScript, you can build on-chain apps.
@base @farcaster_xyz make it easy.
I want to build more apps. Can I get an invite to the Base app for motivation?
