The project is moving ahead and they seem to have chosen a solution for the challenges with privacy. We are interested in working on a project to present a solution to them when they would be looking for a solution about interoperability with public chains. If Celo Foundation and Hyperlane is interested, we could try to present to them Hyperlane when the time comes.
