Ether’s Prometheum Test
The “only U.S.-registered crypto securities platform" is listing ETH in a bold test of the U.S. Securities and Exchange Commission's thesis that most cryptocurrencies are securities.

As crypto regulators have, for years, hemmed and hawed over essential legal questions like “is ether a security?,” the industry has often complained about a lack of legal clarity.
It has been impossible, many have said, to comply with the law because it’s not clear exactly what the law says, or rather how regulators will interpret that law related to something as novel as an internet-era digital asset.
This is an excerpt from The Node newsletter, a daily roundup of the most pivotal crypto news on CoinDesk and beyond. You can subscribe to get the full newsletter here.
We still don’t know, for instance, whether ether is a security or a commodity, though the SEC has breadcrumbed that it’s probably the latter and that the leading securities regulator is not, therefore, responsible for regulating the second most important crypto asset after bitcoin.
But is it?
This week, Prometheum, a weird anomaly in being the “only U.S.-registered crypto securities platform,” announced that it would begin to custody ETH as its first digital asset.
The news is important because it tests two key open questions in crypto — one, whether it’s possible to comply with the SEC when transacting leading cryptocurrencies, and two, who, if anyone, is finally going to adjudicate on ETH classification so we can all go about building the next generation crypto industry.
My colleague, regulation deputy managing editor Jesse Hamilton, summed up the stakes in a masterful dissection of the (very complicated) matter yesterday:
“At that point, [Prometheum] will either be proving the claims of its executives that crypto can be handled in the U.S. in a way that appeases the securities watchdog, or proving the naysayers who argue that it's impossible to meet the SEC's expectations,” Hamilton writes.

“The stakes aren't just high for Prometheum and the rest of the industry, but also for the government agency that has claimed for years that there's a proper way for crypto firms to ‘come in and register’ to do business in the U.S.; Prometheum came in and registered but what happens next is unclear. And while it tests these murky waters, it may also help establish whether the SEC intends to view ETH as a security.”
Prometheum is able to offer both custody and trading in those digital assets because, unusually, it has licenses to do both. That means it can “legally sling Ethereum as a security,” in the words of Fortune’s Jeff John Roberts and hope that “regulators have no choice but to recognize the designation.” In this scenario, Prometheum would then be the only platform for legally trading ether, the security — a pretty nice natural monopoly if you can get it.
The question, then, is whether the SEC, witnessing this anomaly, would step in to finally designate ether a security, or not. Mike Selig, a fintech lawyer at Willkie Farr & Gallagher, says that’s unlikely, given the SEC’s preference the last few years for not saying anything very definite when it comes to crypto. “The SEC is likely to remain neutral on Ethereum,” he says. They have done no favors for ether. I wouldn’t expect it makes one now.” Under the terms of the SEC’s special-purpose broker-dealer, Prometheum has broad latitude to designate assets as securities to list on its platform (for instance, by showing that an asset meets the all-important Howey Test).

How this plays out is anyone’s guess. Jeff John Roberts thinks Prometheum will struggle for clients and that Coinbase and others will fight SEC chair on this as it’s fighting on a host of related issues. But the Prometheum Test shows one thing very clearly once again: the SEC has failed to provide any legal certainty for the crypto industry and as a result has enabled a backdoor actor to come within spitting distance of a legal monopoly. Nature abhors a vacuum, and the crypto industry abhors Gary Gensler’s SEC.

Pudgy Penguins: A New Blueprint for Tokenized Culture

Pudgy Penguins is building a multi-vertical consumer IP platform — combining phygital products, games, NFTs and PENGU to monetize culture at scale.
What to know:
Pudgy Penguins is emerging as one of the strongest NFT-native brands of this cycle, shifting from speculative “digital luxury goods” into a multi-vertical consumer IP platform. Its strategy is to acquire users through mainstream channels first; toys, retail partnerships and viral media, then onboard them into Web3 through games, NFTs and the PENGU token.
The ecosystem now spans phygital products (> $13M retail sales and >1M units sold), games and experiences (Pudgy Party surpassed 500k downloads in two weeks), and a widely distributed token (airdropped to 6M+ wallets). While the market is currently pricing Pudgy at a premium relative to traditional IP peers, sustained success depends on execution across retail expansion, gaming adoption and deeper token utility.
