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. The app runs against public Base RPCs out of the box; an OnchainKit API key and a Neynar key unlock wallet RPC and gift-by-handle lookup. Nothing secret is committed — .env* is gitignored.

Contract addresses, ABIs, and the referral wallet live in src/lib/constants.ts — the single source of truth. The flow is always USDC approve → buyTickets.

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 src/lib/minikit.config.ts is bound to farpot.vercel.app and signed by the original author's Farcaster account — it will not validate on your domain. Regenerate it with the Farcaster Manifest Tool and replace those three values.
3. The REFERRAL_WALLET in constants.ts earns the protocol's 10% referral fee on each sale. Point it at your own address if you deploy your own instance.
