Earlier this month, Gibraltar-based INX Limited officially became the first fintech company to publicly offer blockchain assets registered under the Securities Act. INX's lead U.S. counsel, Mark Selinger of McDermott Will & Emery in New York, does not advertise himself as a cryptocurrency expert, but found himself on the frontier of the industry. His job was to apply 75 years of regulations to a brand-new token and blockchain platform. After three years of back-and-forth with the U.S. Securities and Exchange Commission, Selinger says the final product could advance the practice of regulating digital assets. The Recorder sat down and talked to Selinger.
