“Consensys has inserted itself into the US securities markets, yet failed to act in accordance with the provisions of the federal securities laws to which it is subject and that exist to protect investors,” the Securities and Exchange Commission said in a complaint in federal court in Brooklyn, New York.

A Consensys spokesperson did not immediately reply to an emailed request for comment.

In April, the software firm disclosed it received a notice from the SEC that the regulator would potentially bring an action against the company related to its MetaMask products. Consensys is seperately suing the SEC in federal court in Texas to fend off regulation of the Ethereum blockchain.
