The 10-year-old company said its suit followed three subpoenas issued last year, plus a Wells notice from the SEC that claimed Consensys was violating federal securities laws.So far this year, the SEC has sent Wells notices, filed lawsuits, or reached settlements with a host of crypto firms focused on ethereum and decentralized finance, including ShapeShift, TradeStation and Uniswap. The agency is also reportedly investigating the Ethereum Foundation.Less than two weeks ago, Consensys declared victory in its fight with the SEC.”The Enforcement Division of the SEC responded by notifying us that it is closing its investigation into Ethereum 2.0 and will not pursue an enforcement action against Consensys,” the company wrote in a statement June 18.Consensys said in an emailed statement Friday that the action is part of an “anti-crypto agenda” at the SEC.”This is just the latest example of its regulatory overreach — a transparent attempt to redefine well-established legal standards and expand the SEC’s jurisdiction via lawsuit,” the company said. “We are confident in our position that the SEC has not been granted authority to regulate software interfaces like MetaMask.”Don’t miss these insights from CNBC PRO
