That depends, Ubisoft Quartz is on its own blockchain IIRC and there's no guarantee you can submit transactions without a Ubi account, or even that the signing key isn't just stored in your Ubi account.
Also, just to check on which blockchain it's on, I tried opening their FAQ page to see a "not available in your region" message (despite the Ubi store being available here, Israel). Hilarious.
