Drawcast
Draw and challenge friends
The problem Drawcast solves
Drawcast addresses the need for more engaging, social, and fun experiences within the onchain ecosystem. It offers playful interactions that can onboard new users.
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.
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.

Challenges I 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.
