Your First Mini App Prompt

Now that you’ve seen how to write effective prompts and where to find help, it’s time to build your first interface. In this section we’ll focus on the visuals: screens, flows, buttons, and layout. No onchain features yet—just getting the look and feel right so you can move fast.
Use a split-screen setup if your display allows. Keep Vercel V0 open in one window for generating UI, and a second window for ChatGPT (or another LLM) plus a Google Doc for drafting and iterating on your prompt, and skimming docs as needed. This reduces context switching and speeds up iteration.
1

Draft your prompt with intent

Start in your notes or a Google Doc. Write a short, focused prompt that describes the core user journey, key screens, and any visual preferences. Keep it specific and concise.
2

Set up your workspace

Arrange two windows side by side. Left: Vercel V0 for UI generation. Right: your LLM and notes for refining the prompt and searching documentation.
3

Generate the first UI in V0

Paste your prompt into V0 and generate an initial interface. Review the output carefully: layout, component structure, naming, and accessibility.
4

Iterate with fast feedback loops

Identify issues or gaps, refine your prompt, and regenerate targeted parts (not always the entire UI). Repeat until the flow matches your intent.
5

Export when satisfied

When the interface feels right, download the code from V0. You’ll wire up functionality and any onchain features later in your local environment.

Example: Frontend-Only Prompt Template

Use (and adapt) this prompt to have V0 generate a clean starting interface for your Mini App. Keep it UI-first—no wallet hooks or chain calls yet.
