The crypto ETF market is no longer just about Bitcoin and Ethereum. Grayscale has now confirmed this officially, and the numbers speak for themselves.

Krista Lynch, a senior figure at Grayscale, has stated that the SEC‘s listing standards now cover approximately 15 tokens — opening the door to structural diversification across regulated investment products.

And the strongest signal of this shift? The Zcash ETF has just crossed the symbolic threshold of $1 billion in assets under management. A milestone that deserves a closer look.

Why Grayscale Is Calling This a “New Phase” for Crypto ETFs

Since the approval of spot Bitcoin ETFs in January 2024, followed by Ethereum ETFs a few months later, the market has been waiting for the next step. Grayscale believes that step is now underway. Krista Lynch clarifies that the SEC‘s current listing rules technically allow ETFs to be launched on around fifteen digital assets — without requiring new regulatory approvals on a case-by-case basis.

This regulatory opening represents a paradigm shift. Until now, every new product required a lengthy and uncertain approval process. Issuers can now be selective and strategic, targeting tokens that already have sufficient liquidity and a mature market infrastructure. Grayscale is clearly positioning this phase as an opportunity for institutional diversification beyond the market’s top two assets.

For institutional investors, the stakes are significant: gaining exposure to alternative assets through regulated vehicles, without the direct risks associated with custody or the operational constraints of crypto wallets. That is precisely what ETFs offer — and what the market is beginning to value in second-tier tokens.

Zcash ETF at $1 Billion: Market Signal or Outlier?

The Zcash ETF crossing the $1 billion AUM mark is a signal that is hard to ignore. Zcash (ZEC), a privacy-focused token powered by zk-SNARKs technology, is not a top-tier asset by market capitalization. Yet its ETF is attracting significant institutional flows — suggesting genuine demand for products tied to specific investment theses, in this case privacy blockchain.

This success is far from trivial in the current regulatory environment. The SEC had historically shown reluctance toward privacy tokens, associating them with AML/KYC compliance risks. The fact that a Zcash ETF has reached $1 billion in AUM indicates that the US regulator has adopted a more pragmatic stance — or at least a more nuanced one — toward this asset category.

For other ETF issuers, this precedent opens up concrete opportunities. If Zcash can generate this level of traction, tokens such as Solana, Litecoin, and other assets with solid market infrastructure could quickly join the product pipeline. Competition among issuers — BlackRock, Fidelity, Grayscale, Bitwise — is set to intensify in this segment.

Which Tokens Could Benefit From This Momentum?

Grayscale‘s statement regarding the 15 tokens eligible under SEC listing standards does not come with an official list. However, the implicit criteria are identifiable: sufficient liquidity on regulated US markets, presence on compliant exchanges, a robust price history, and the absence of security status under current case law. These filters mechanically narrow the field to established assets.

Among the natural candidates are Solana (SOL), for which several ETF applications are already under review at the SEC, as well as Litecoin (LTC), Chainlink (LINK), and Avalanche (AVAX). Each presents a liquidity profile and infrastructure maturity compatible with the requirements of an exchange-listed product. The race to file applications with the SEC is expected to accelerate over the coming months.

This movement marks a gradual institutionalization of the altcoin market. Inflows into these new ETFs could structurally alter the price dynamics of these assets — reducing long-term volatility and attracting a base of traditional investors who would never have bought directly on a crypto exchange.
