TLDR: The Onchain Summer Buildathon invited builders everywhere to unleash their creativity onchain. Over 1,250 final projects were submitted from 7,500+ builders around the world, making this the largest onchain hackathon. Now, it's time to spotlight those who rose to the challenge.

To kickoff Onchain Summer, Base and leading builders sponsored a global online hackathon, dedicated to bringing the world onchain. From May 31st - June 30th, builders around the world worked on projects across payments, commerce, creator tools, social platforms, gaming, trading, discovery, and URL <> IRL use cases.

Over 1,250+ projects were submitted from 7,500+ builders around the world, making this the biggest onchain hackathon ever.

We were so blown away by the volume and creativity of the projects that we expanded the prize pool from 200 ETH to 250 ETH to recognize and reward more builders who built exceptional products on Base.
