Build. Launch. Scale. Earn.

This summer, we're recognizing the most impactful onchain applications that bring people around the world onchain. The Onchain Summer Awards is a retroactive awards campaign designed to spotlight the most innovative, engaging, and widely-used mini apps and consumer apps across the Base ecosystem.

From July 9 to August 25, we’ll be tracking key engagement metrics to identify and celebrate the apps and people that are leading the charge in bringing the next billion users onchain.

The top teams will earn prizes, and/or an invitation to Basecamp where they will be spotlighted during our live OCS Awards Ceremony.
