Getting started

npm install
cp .env.example .env.local   # then fill in the values
npm run dev

Open http://localhost:3000.

Environment

See .env.example. You'll need an OnchainKit API key for NEXT_PUBLIC_ONCHAINKIT_API_KEY. Nothing secret is committed — .env* is gitignored.

Deploying your own

1. Deploy to Vercel and set the env vars (set NEXT_PUBLIC_URL to your final domain).
2. Re-sign the manifest for your domain. The accountAssociation in minikit.config.ts is bound to basepaint-mini.vercel.app and signed by the original author's Farcaster account — it will not validate on your domain. Regenerate it with npx create-onchain --manifest (or the Farcaster Manifest Tool) and replace those three values, plus baseBuilder.ownerAddress.
