Onchain Summer Continued

Working with Base and others to support onchain builders in Build v5

It’s been incredible to see the energy around Onchain Summer in June. But summer is just getting started, and we’re working with Base and an amazing group of organizations to keep the energy flowing in July during Build v5

Over the past 4 programs, Build has welcomed thousands of builders, seen hundreds of projects launch and find traction (including 165 on Base!), and helped builders earn >$1M in grants of cash and credits. v5 is set to be our biggest and best program yet.

We're welcoming builders to continue making progress on their buildathon project or start something new. We have an incredible ecosystem of organizations providing grants and other opportunities for builders, including showcases throughout the rest of Onchain Summer.

Check out more details below, and apply by June 7th with your existing project or a new idea at
