It’s Onchain Summer 🟡 and Base is open for bridging

By Jesse Pollak

TL;DR: Since we announced Base, our mission has been clear and consistent: bring the next million builders and billion users onchain. Today, we’re thrilled to announce our next step in that journey: Base is now open for bridging, and mainnet will be open for everyone on August 9. To celebrate, we’re helping throw a party: it’s Onchain Summer!

—

We’re committed to uplifting builders and creators - the tinkerers, the curious, the ones who live in and see the future - in real life, online, and onchain. We believe in the transformative power of that builder community: when you combine new ideas, technologies, and people, you have an unwavering force for change. And we believe that change is an onchain future that enables an open, global economy that increases economic freedom and puts everyone on a level playing field.

Our next step begins today: Base is now open for bridging and Base mainnet will open for everyone and everything on August 9th. Over the next week, you’ll begin to see dapps across the onchain ecosystem turn on Base support and new ones launch.

It’s Onchain Summer — and we’re celebrating

To celebrate the general availability launch of Base on August 9th, we’re kicking off Onchain Summer, a month-long onchain festival put on by 50 of the best builders, brands, products, artists, and creators. Every day in August, they’ll be bringing you something fun thing to do onchain, highlighting art, music, gaming, advocacy, and more.

Empowering everyone with 100+ ETH in grants

We have an incredible group of creators building Onchain Summer — but we know that bringing the world onchain is bigger than any one of us, and we want everyone to get involved. We are thrilled to announce grants for those building and creating on Base this summer together with PropHouse .
