Drawcast
Draw and challenge friends
About
The problem it solves **Problem** Drawcast addresses the **need for more engaging, social, and fun experiences** within the onchain ecosystem. It offers playful interactions that can **onboard new users and keep them onchain**. **Solution** Drawcast is a mini app where users draw prompts and challenge their friends, bringing the spirit of web2 social games into the onchain world. What makes Drawcast unique is that it **aims to blend familiar user experience with onchain innovation** and utility: - Users can **coin their drawings** on Base, turning sketches into collectibles or monetizable content (using Zora's SDK). - Premium features like extra colors and profile badges are unlocked through fully **onchain payments** via Daimo Pay. Users can pay with various tokens on Base. - Every drawing shared on Farcaster could **earn tips**, turning fun into fuel for viral, organic growth! Drawcast lowers the barrier for new users to get onchain in a natural, fun way, without needing to understand complex underlying wallet and other mechanisms. We need 1000 times more use cases and apps to bring the next wave of people-chain, and Drawcast aims to take its part. **Traction** Week 1 retention: 20-23%       *Data from 19 Jun* **Market potential** Assuming Drawcast captures 1% of the market and 1% of the users pay 3-5 USD per month via various monetization options.  **Future plans** Near-term The number one priority is to improve the app's core loop to make the app stickier, ideally reaching 40% week 1 retention.

How it's made
Challenges we ran into **Validating farcaster.json** Validation isn’t always straightforward—many builders, including myself, run into issues here. After lots of trial and error, I finally got it working. Persistence pays off. **Dynamic Share Preview Images** I wanted users to be able to share their drawings with actual previews. It took some experimenting to get right, but I eventually figured it out. A clear guide on setting up dynamic share images would definitely help others. **Coining Issues** While testing coining, I noticed a strange bug: On desktop, the preview showed 10M tokens received. On mobile, it showed just 1 token. I spent quite a bit of time debugging until I connected with some fellow builders on Warpcast who confirmed the mobile preview is currently buggy. Lesson learned: I should’ve tested the full coining flow to see the actual transaction results instead of relying only on previews.
