Upcoming events

Remember when new tech was... exciting?

When tech was about more than bigger screens, exclusive clubhouses, the un-bundling and re-bundling of features? The days when you went out of your way to try the latest thing. Even if it wasn't perfect. Because it wasn't perfect. Because you could see where this was going. Well, have we got news for you.

All over the world, hundreds of thousands of developers, users, hobbyists, creators, artists, and market makers spend their days and nights thinking, building, talking about Ethereum because we are... excited. We're excited by the idea that Ethereum can change things. That Ethereum is a fulcrum we can use to change money, finance, the web, the way software works and the way power is distributed.

This September, we invite you to come learn what all the talk is about. ETHOnline is our way of celebrating an incredible year in Ethereum, bringing the community together at a time when we're kept apart. Join over 1,000 likeminded engineers, designers, and creators to build and learn for 3-weeks. Focus on building a new product/protocol for the hackathon, learning at the summits and workshops, and gain valuable feedback from ecosystem professionals along the way.

Whether you're here to build or here to learn, we hope you'll join us.

Build with the entire ecosystem at your back

At ETHOnline, you'll have the support of a huge community of experts, mentors, sponsors, developer advocates, and other community members who want to help you build something awesome.

We'll introduce you to teammates, connect you with mentors, unblock technical problems, and help you deliver a working product that pushes the web3 ecosystem forward.
