Not yet 🤔 It's on the roadmap though 😊 grain is a relay implementation I've been working on. Probably not much difference for the end user but my goal is to make a highly configurable relay that can work for a lot of different use cases by just changing the config. I want to make it easy for a non technical user to spin up their own relay for their own purposes. Check the issues for the roadmap
