Fixed the check-ins bug! The app is now 95% ready Context for crypto devs building on Base / Farcaster: Initially my app inside Farcaster was stuck on a loading screen. After some digging, the fix was adding a vercel.json file and setting an API_KEY in Vercel (was told to temporarily use ātestā) That fixed the app load, but all check-ins broke and previous ones showed as zero, even though the site itself worked. > Root cause OnchainKit uses this API key to connect to Base via Coinbase RPC. With an invalid key, the app couldnāt read data from the smart contract, so all check-ins appeared as 0 despite being correctly stored onchain. > Fix Created a real API key in the Coinbase Developer Portal and added it to Vercel. Important detail: itās the Client API Key (public, meant for frontend) > Current blocker I canāt more log into Base Dev. After entering the email code, it just infinite-loads Rate my app! @base.base.eth @jesse.base.eth

Built my first app on Base š·š¼ Wrapping up this small challenge where since Jan 9 I was sharing how I built an app from scratch. In practice, itās a simple onchain habit tracker I canāt really code, so the whole build was done with AI From idea to a working version took ~20 hours over 10 days The hardest part wasnāt the code, but the integrations: ā¢ Base app ā¢ Farcaster mini-app ā¢ wallet + account linking Deployed the smart contract via Remix, shipped the site with GitHub + Vercel. What started as ~200 lines of code turned into ~1600 with UX and mobile support. Why I did it: - to understand how Base / mini-apps actually work - to get on the radar as a dev - to maybe build something bigger in the future The app is still very raw, some check-ins broke, but: transactions work, users are counted - so itās alive If this gets some traction, Iāll drop a step-by-step guide on how to build your own app from scratch. For now: throw the Base docs into an AI and just start building.
