Hello from the Ethereum Foundation Grants Team!
As we progress full throttle toward Devcon 4, we are excited to announce Wave 4 of the Grants Program! A heartfelt thank you to all the amazing community members who have submitted their inventive proposals to enhance our ecosystem. We owe our existence to the dedication and effort you invest in Ethereum. As the program continues to evolve, we will increasingly engage more community participants in the decision-making process. The Grants Program today is significantly advanced from earlier this year, largely due to the valuable feedback received from the community, enabling us to offer improved public tools and infrastructure.
If this is your first time hearing from us, our last announcement offered a detailed overview of the program’s history, funding summary, and procedures. You can find that post here, and see guidelines and more information here.
Without further delay…
We are delighted to declare our Wave 4 Grantees!
