The United States Securities and Exchange Commission (SEC) has charged Rivetz over an alleged illegal securities offering that fetched around $18 million. Rivetz was founded in 2013 and the now-defunct blockchain hardware firm has been accused of generating $18 million via an unregistered securities offering between July and September of 2017 from more than 7,200 investors. The SEC’s Sept. 8 complaint names defendants Rivetz Corp., founder Steven Sprague and the firm’s subsidiary Rivetz International. The ICO revolved around the RvT token, which the SEC states was promoted and sold as an investment opportunity and used to capitalize on Rivetz’s business in building an app, ecosystem and cyber security hardware.
