The US Securities and Exchange Commission has charged the crypto market-maker Cumberland DRW with acting as an unregistered dealer.

The agency, which revealed the charges Thursday, alleged that the Chicago-based firm has been “operating as an unregistered dealer in more than $2 billion of crypto assets offered and sold as securities.”

“Despite frequent protestations by the industry that sales of crypto assets are all akin to sales of commodities, our complaint alleges that Cumberland, the respective issuers, and objective investors treated the offer and sale of the crypto assets at issue in this case as investments in securities, and Cumberland profited from its dealer activity in these assets without providing investors and the market with the important protections afforded by registration,” Jorge G. Tenreiro, acting chief of the agency’s crypto assets and cyber unit, said in a statement. 

In the complaint, the SEC alleged that the firm “has made available for trading many crypto assets offered or sold as investment contracts and, therefore, as securities.” The agency cited POL (formerly MATIC), SOL, FIL, ALGO and ATOM.

Such inclusions are likely to spur further criticism of the agency, given the SEC’s recent step back from the use of the term “crypto asset securities” in some of its more high-profile court cases. The SEC’s critics have accused the agency of specifically targeting the crypto sector.

Cumberland echoed those complaints in a statement published Thursday, in which the market maker pledged to defend itself. The firm said it had become “the latest target of the SEC’s enforcement-first approach to stifling innovation and preventing legitimate companies from engaging in digital assets.”

“We are not making any changes to our business operations or the assets in which we provide liquidity as a result of this action by the SEC,” Cumberland said. “We are confident in our strong compliance framework and disciplined adherence to all known rules and regulations — even as they have been a moving target (it wasn’t long ago ETH was claimed to be a security).”

Every distributed system inherits the physical limitations, or advantages, of the network it runs on. Physics-bound systems can optimize their execution layers, compress their state, and parallelize their runtime, and still lose time they cannot recover to the speed of light through fiber and the routing decisions of carriers that are not optimized for consensus. The public internet routes traffic by least cost, not best performance. For a system where the order and timing of messages determine who earns and who loses, that is a structural tax and a measurable networking design flaw for traders.
