"I deployed to IPFS and it works." Did the CID change? If not, you deployed stale output. Did routes work? Without trailingSlash: true, every route except / returns 404. Did you check the OG image? Without NEXTPUBLICPRODUCTIONURL, it points to localhost:3000.
"I'll set up the project manually." Don't. npx create-eth@latest handles everything — Foundry, Next.js, RainbowKit, scaffold hooks. Never run forge init or create Next.js projects from scratch.
When using fork mode, the frontend target network MUST be chains.foundry (chain ID 31337), NOT the chain you're forking.
The complete build-to-production pipeline for Ethereum dApps. Fork mode setup, IPFS deployment, Vercel config, ENS subdomain setup, and the full production checklist. Built around Scaffold-ETH 2 but applicable to any Ethereum frontend project. Use when deploying any dApp to production. Source: austintgriffith/ethskills.
