It’s always fun to hear about new grants as they’re awarded, but what happens after the announcement? In this series, we’ll check in on a couple of projects that are well underway - or already at the finish line. Read on to learn about some recent milestones and achievements by grantees!

Grantee Raman Shalupau has recently completed his funded work on the QDH user interface, MACI smart contracts and documentation. For a more in-depth look at how QDH works, this demo a provides a video walk-through of both the web interface and the back end components. You can find Raman Shalupau on Twitter @ksaitor, or contribute to Quadratic Dollar Homepage on Github.
