We are indeed working with ISDA on implementing a clearing workflow for OTC derivatives in DAML. See the press release here. While the initial focus is interest rate swaps the same approach will work for any CDM-supported contract. We’re going to open source a demo application soon, I’ll update this thread once it’s available. Feel free to direct people to the forum for more info, or refer them to the contact form on our company website if they’re looking for commercial engagements.
