The problem BasedNews solves

Keeping up with crypto and onchain developments can be overwhelming because most updates are buried inside long-form articles, often hidden behind premium subscriptions. BasedNews solves this by providing:

1. AI-Powered Summaries: Concise article summaries with sentiment analysis (Bullish/Bearish/Neutral)
2. Base Ecosystem Focus: Curated news specifically for Base chain developments and tokens
   3 Live Portfolio Tracking : Real-time wallet balances for ETH, USDC, DEGEN, AERO, BRETT, TOSHI
3. Farcaster and Base App Integration : Native sharing and authentication within Base app
4. Interactive Charts : Live price data and trading insights for Base ecosystem tokens
5. One-Click Sharing : Direct article sharing to Farcaster and Base App with custom messages

Users can quickly understand market-moving news, track their Base portfolio, and engage with the community without paying any fees or spending hours reading and finding articles conclusion.

Challenges I ran into

Challenges I ran into

1. Vercel Deployment Issues
   Multiple build failures with "Missing './minikit' specifier" errors requiring 3+ hotfixes and aggressive cache-busting strategies.
2. React Hooks Violations
   React Error #310 from conditional hook calls, blank dashboard crashes, and complex provider hierarchy issues (MiniKitProvider).
3. Farcaster SDK Integration
   OnchainKit import conflicts, non-existent useAuthenticate hooks, and composeCast() failures in Base app environments.
4. Multi-API Coordination
   Integrating CoinGecko rate limits, Base RPC calls, real-time balances for 5+ tokens, and sequential ranking systems.
5. Cross-Platform Compatibility
   Environment detection for Base app vs browser, multiple wallet providers, mobile responsiveness, and theme consistency.
6. Mini App Compliance
   Farcaster manifest validation (frame→miniApp→miniapp), CSP violations, meta tags, and SDK initialization timing issues.

Smart Contract Address(es)

Currently, BasedNews operates as a Web3-native app without requiring dedicated smart contracts. Instead, it integrates directly with:

Base Mainnet RPC: Real-time balance fetching
ERC20 Token Contracts: USDC, DEGEN, AERO, BRETT, TOSHI etc tracking
Farcaster Protocol: Social graph and identity resolution

Minting articles as Zora NFT collections for permanent on-chain news archival, and implementing personalized keyword-based news curation with AI-powered content filtering tailored to individual user preferences and trading strategies.
