Consensys has taken legal action against the U.S. Securities and Exchange Commission (SEC).

The lawsuit, filed on Thursday, aims to stop an impending SEC crackdown on Consensys MetaMask wallet and seeks a crucial ruling on the classification of Ethereums native token, Ether.

Consensys Challenges SECs Stance

The filing asserted, The U.S. Securities and Exchange Commission’s (SEC) threatened regulation of Ether as a security would jeopardize the United States’ ability to use Ethereum and similar blockchain technology.”

Consensys is pushing for a federal court declaration affirming that Ether is not a security. It argues that any investigation based on ETH being a security would violate the company’s Fifth Amendment rights and the Administrative Procedures Act.

The lawsuit also seeks to clarify that MetaMask, Consensys’ wallet product, does not function as a broker under federal law, and its staking service does not break securities laws.

Consensys received a Wells notice from the SEC on April 10, indicating the SEC’s intent to pursue enforcement action against the company for alleged violations of securities laws through its MetaMask wallet product. The complaint also references the SEC’s prior stance on Ethereum, citing former director Bill Hinmans 2018 speech, which classified Ether as a commodity.

Consensys highlights the SEC’s inconsistency in its approach and points to the Commodities Futures Trading Commissions (CFTC) jurisdiction over Ethereum derivatives as further evidence of ETHs commodity status.

It alleges that this shift constitutes an “about-face” that contradicts the Constitutional requirement of fair notice under the Due Process Clause.

Consensys also invokes the major questions doctrine, a legal principle that limits federal regulators from overstepping their Congressional mandates. The company warns of serious consequences for both the Ethereum network and Consensys should the SEC’s actions proceed unchecked.

Gensler’s Crypto Crackdown

The lawsuit against the agency comes amid SEC Chairman Gary Genslers aggressive crackdown on major crypto players, such as Coinbase and Uniswap.

Genslers approach has included issuing subpoenas to firms and developers for documents related to their interactions with the Ethereum Foundation, a nonprofit supporting the networks development.

Critics within the crypto industry are angered by Genslers tactics. They argue that the SEC has not provided clear regulatory guidelines tailored to blockchain technologys unique characteristics. Gensler denies these criticisms, asserting that existing securities laws are sufficient and blaming the crypto industry for non-compliance.

Consensys lawsuit, filed in the Northern District of Texas, aligns with similar preemptive legal actions taken by groups like the Blockchain Association and companies like Legit Exchange. Despite these legal actions, Gensler continues to pursue Ethereums staking feature as the basis for the SECs recent legal stance.
