The rule, proposed by the SEC in January, would expand the agency’s definition of an exchange to include a broader array of communication systems that enable prospective buyers and sellers of securities to find each other. Such entities would have to register with the SEC either as exchanges akin to the New York Stock Exchange, or as a category of broker-dealers called alternative trading systems, or ATSs, which perform exchange-like functions but face lighter regulations.
“The proposal may not have been designed with this developing ecosystem in mind,” lawyers for Andreessen Horowitz, which invests in crypto projects, wrote in a comment letter to the SEC. “Nevertheless, broadening the definition of an exchange in a manner that could apply to DeFi protocols, at a time when it is unclear which digital assets are considered securities, will create tremendous regulatory uncertainty and deter responsible innovation.”
