TL;DR

  • Winklevoss Asset Services filed October 6 for a spot Zcash ETF seeking a Nasdaq listing under WINK.
  • The proposed annual sponsor fee is 0.25%; up to $100 million of affiliated purchase interest is nonbinding.
  • Gemini would custody the ZEC, while the preliminary filing leaves key service-provider and launch details unresolved.

WILMINGTON, Delaware, October 6, 2026

Winklevoss Asset Services filed October 6 for a Zcash ETF charging a proposed 0.25% annual fee, with up to $100 million of nonbinding affiliated purchase interest, adding another entrant to the U.S. spot-crypto fund market as ZEC’s latest completed session ended near $1,338.

The proposed Winklevoss Zcash ETF would hold ZEC directly and seek a Nasdaq listing under WINK. Its preliminary SEC registration statement names Gemini Trust Company as custodian and Cypherpunk Technologies as a Zcash ecosystem adviser.

ZEC fell 1.09% to $1,337.73 in the completed October 5 session, with a range of $1,281.76 to $1,361.90, according to Investing.com’s historical table. That closing price was 8.95% above September 6, a comparison that describes the preceding month rather than a response to the filing.

The prospectus says Winklevoss Capital Fund, through affiliates, has indicated interest in buying shares. It explicitly qualifies that interest: purchases are not binding commitments and could amount to more, fewer or no shares.

The filing enters a market where The Block reports Grayscale’s spot Zcash product began trading in August. WINK is a separate proposal from Grayscale’s later Zcash income ETF filing, which seeks option-based distributions rather than direct coin ownership.

WINK’s 0.25% fee comes with conditional funding

The proposed sponsor fee equals 25 basis points annually. On a hypothetical constant $10,000 holding, that rate corresponds to about $25 a year before other costs. This is an illustration of the quoted rate, not a return estimate or a complete trading-cost calculation.

The sponsor would cover normal operating expenses from its unified fee. Extraordinary expenses can remain payable by the trust, while brokerage charges and differences between buying and selling prices affect investors separately.

That separates the recurring fund charge from the cost of entering or leaving a position. A low advertised annual rate alone cannot establish which product produces the best realized result, particularly before trading spreads and tracking performance exist.

The $100 million figure describes potential share purchases through authorized participants or market brokers. It should not be treated as money already deposited, ZEC already acquired or a minimum amount the fund must attract.

At the proposed rate, $100 million of constant holdings would imply roughly $250,000 in annual sponsor fees. Both assumptions are hypothetical: the purchase interest can change, and asset values fluctuate. The calculation illustrates why a large headline funding number and a modest fee can coexist.

The new filing supplies a concrete price of access to compare with other Zcash investment wrappers. Earlier 21shares European Zcash ETP coverage concerned a different issuer and market. Availability in Europe does not establish that this Nasdaq proposal can already be traded.

Nasdaq Zcash filing leaves launch details open

The document is a preliminary S-1, not evidence of an effective registration or a trading debut. It leaves the pricing benchmark, certain service providers, seed subscription figures and basket size incomplete. No firm launch date is established.

Those blanks affect practical questions beyond the ticker. A benchmark determines the reference value used to calculate a fund’s assets, while creation and redemption arrangements determine how specialist financial firms exchange large blocks of shares with the trust.

The proposed objective is ZEC price exposure after expenses. It is distinct from a promise to pay interest, distribute an income stream or outperform the coin. The prospectus describes passive holdings without leverage or derivatives.

The sponsor was formed October 1, five days before this filing. The prospectus distinguishes its personnel’s experience from the new entity’s own record, saying the sponsor has no prior experience managing pooled investment vehicles. That disclosure adds an operational question alongside the proposed fee: how the newly formed organization will run the trust and supervise its service providers.

An SEC investor bulletin about spot bitcoin and ether products explains the broader structure: exchange-traded commodity trusts can use the ETF label while operating outside the Investment Company Act of 1940. WINK’s prospectus likewise says it is not registered under that act.

The bulletin is an explanation of bitcoin and ether products, not a Zcash approval. Its distinction is relevant to evaluating WINK’s disclosed legal structure. A familiar name and brokerage interface do not by themselves establish the protections of a conventional registered investment fund.

The same bulletin explains that exchange-traded shares can deviate from their underlying asset’s price and that sponsor fees reduce the assets represented by each share over time. Moving coin custody to an institution changes who handles the keys; it does not remove the underlying market risk.

Gemini custody differs from Zcash shielded payments

Gemini is an affiliate of WINK’s sponsor, a relationship disclosed in the prospectus. Its proposed role is to hold the trust’s ZEC. Investors purchasing ETF shares would hold a securities position rather than manage the underlying blockchain wallet.

The filing identifies potential conflicts in selecting affiliated providers because the arrangement can increase revenue for the sponsor’s affiliates. Naming a regulated custodian establishes a proposed responsibility, not proof that commercial incentives are identical for the sponsor and shareholders.

Zcash’s own explanation of shielded and transparent addresses describes a different function. Shielded transactions can protect financial information, while transparent addresses expose it publicly. These are network transaction features, separate from a fund’s share-trading mechanics.

In its unified-address announcement, Gemini described withdrawals to unified addresses and continued deposits into transparent addresses. That retail exchange workflow should not be assumed to describe WINK’s institutional custody agreement or grant shareholders personal withdrawal functionality.

Buying a security linked to a privacy-oriented coin therefore does not give the investor the ability to make shielded payments from the fund’s holdings. Exposure, custody and transaction privacy answer different questions.

Cypherpunk’s advisory role can include technical guidance and coinholder polling assistance. It does not mean ETF shareholders direct Zcash development. The preliminary prospectus says the trust does not expect to participate in current coinholder polls, which require shielded coins in a self-custodied wallet.

Protocol development remains a separate source of change. Zcash’s NU7 testnet work on faster blocks concerns network operations. An investment-product filing does not establish a mainnet upgrade, and a testnet upgrade does not establish an ETF launch.

Fear & Greed Index

October 6, 2026
73 Greed

Alternative.me’s Bitcoin-focused sentiment index read 73, or Greed, versus 70 a day earlier. It supplies broader crypto-market context, not a measure of WINK subscriptions or Zcash-specific demand.

As of October 6 at 19:06 UTC, the reviewed filing establishes proposed terms rather than a completed offering. The next evidence is an amended, completed prospectus, effective registration, listing confirmation and actual purchases. None can be inferred from nonbinding interest alone.

Frequently Asked Questions

Has the Winklevoss Zcash ETF launched?

The October 6 preliminary S-1 does not establish a launch. It seeks a Nasdaq listing under WINK, and securities cannot be sold until the registration statement is effective.

What fee would the WINK Zcash ETF charge?

The proposed annual sponsor fee is 0.25%. Extraordinary expenses and brokerage trading costs can be additional.

Is the $100 million purchase interest guaranteed?

No. Winklevoss Capital Fund's indication of interest is nonbinding. Purchasers could buy more, fewer or no shares.

Who would hold the WINK ETF's Zcash?

Gemini Trust Company, an affiliate of the sponsor, is the proposed ZEC custodian. ETF shareholders would own shares rather than control the underlying wallet keys.

Does a Zcash ETF provide shielded payments?

ETF shares provide investment exposure. They do not give shareholders a personal Zcash wallet or the ability to initiate shielded blockchain payments.
