Gruz Game 04

Base App mini app scaffold (Next.js + wagmi + Farcaster Mini App SDK).

Based on the Build an app on Base guide and the shared structure from gruzgame03, without game-specific logic or deployed contract addresses.

Stack

• Next.js App Router
• wagmi + viem (base mainnet)
• @base-org/account connector
• Farcaster Mini App SDK + Quick Auth

Environment

Copy .example.env to .env.local:

# optional — only for localhost override
NEXT_PUBLIC_URL=http://localhost:3000

Vercel: no manual env required (same as gruzgame02 / gamegruz1).

• Site URL: auto from VERCEL_PROJECT_PRODUCTION_URL / VERCEL_URL via lib/siteUrl.ts
• Contract address: hardcoded in lib/contracts/gruzgame04Onchain.ts

Deployed contract (Base Mainnet): 0x9ABF08d1C298Ada4FC0E8FEB1a71b2FbFBf10fd9

Builder Code: bc_w6mg1cwt — appended to every tap / checkIn tx calldata for base.dev attribution.

Suffix (ERC-8021): 0x62635f77366d67316377740b0080218021802180218021802180218021

Run

npm install
npm run dev

Next steps

1. Update farcaster.config.ts (name, assets, account association).
2. Add public/ icons, splash, hero images for publishing.
3. Add contract ABI/address under lib/contracts/ when ready.
4. Replace app/page.tsx with your game UI and onchain flows.
