Polygon Labs has completed its acquisition of Coinme, making Polygon a U.S.-regulated payments business and bringing regulated U.S. money movement into the Open Money Stack (OMS). Polygon Foundation CEO Sandeep Nailwal announced the milestone, framing Polygon PoS as now operating under U.S. money-transmission rules; Polygon's official account amplified the news with a video post: "Regulated money movement in the United States. Now powered through Polygon Open Money Stack."
