Virtual or In Person

It’s been over a year since the Ethereum community has been able to connect in-person. At ETH CC Hackathon 2021, you will get the opportunity to reconnect with the community, foster your developer ecosystem, and crowdsource novel projects built on your infrastructure.

Developers will get the chance to collaborate directly with top teams and experts in the space in an intimate, creative setting. Sponsors will engage with developers to brainstorm novel ideas, solve technical hurdles, and connect teammates and mentors to help deliver projects.

Join in-person to work with sponsors and mentors directly, or if you are participating online join the sponsor Discord channels for support.
