Leverage the social context!

You’re building inside a social network - don’t waste that context.

- Pull in usernames, avatars, and bios from their FC profiles.
- Show activity feeds: “your friends just did X.”
- Add leaderboards, badges, and stats - competition fuels engagement.

Create Sharable Moments!

Make it effortless and fun for users to cast what’s happening.

- Add a “Share to Warpcast” button at key moments.
- Embed the mini-app URL in the cast.

Example:
- Mint an NFT → Share it in the feed
- Play Game → Share score

Design for Feed Virality!

Your mini-app should look good in the feed - that’s where new users will discover it.

- Make the preview image eye-catching and legible in small format.
- Include social proof directly in the preview (e.g., avatars of active users, usage stats).

Example: Farville

Add Friendly Entry Points!

Make it easy to jump in.

- Support deep linking with context (e.g., invite URLs, challenge links).
- Autofill names and avatars from Farcaster so onboarding feels instant.

Reward people!

People love to flex. People love dopamine.

- Highlight who did what inside the app (recent activity, “top player,” etc).
- Let people earn or collect things while using it, a badge, an early access.

Keep the Loop Tight!

- Interact → get feedback → share → bring others in → repeat.
- If someone uses your app and no one else knows, you failed.

Use Notifications to Bring People Back

- Farcaster lets you reach users where they already hang out: their Warpcast notification inbox.
- Leverage this natively social push channel to re-engage and spark action.
- Be mindful not to spam.

Plan the Launch Like a Pro!

The launch phase can make or break virality.

- Consider launching with a challenge or leaderboard to fuel early engagement.
- Add a referral or pre-save system before going live - it helps build early momentum and gives you a solid user base to notify when you launch.
