​
Load Time

  • Apps should load within 3 seconds, and in-app actions should complete within 1 second.
  • Always show a loading indicator when an action is in progress.

​
Onboarding Flow

  • When a user opens your mini app for the first time, they should see a brief, informative screen explaining what the mini app does and how to get started. Keep this limited to 3 screens, and use succinct language and images.
Example of an informative onboarding flow:

​
User Information & Privacy

  • Only ask for personal information when absolutely necessary. Give users context and explain the value of using the app before asking for private information.
  • Always explain why the information is needed. Respect user privacy and data minimization principles.

​
User Profile

  • Show the user’s profile somewhere on the screen, and include their avatar and username used on the Base app
  • Avoid showing 0x addresses in your mini app.

​
App Description

  • Your mini app should have a clear, simple value proposition that makes sense to anyone.
  • Describe what your app does and why it matters in one sentence.
  • Keep your messaging human, concise, and benefit-focused.
Examples: “Earn and borrow on your terms”, “Create and share art that lives onchain”

​
App Cover Photo

Do’s ✅
  • Your app’s visuals should make users want to click in and explore.
  • Include a high-quality cover image that feels trustworthy and engaging.

Example of a clear app cover photo:

    • Size: 1024×1024px
    • Format: PNG (no alpha transparency)
    • Defined via iconUrl in farcaster.json
