Key points

  • Winklevoss Asset Services filed an S-1 registration statement with the SEC on Oct. 6, 2026, for the Winklevoss Zcash ETF 1.

  • Cypherpunk Technologies was selected as the trust's ecosystem partner to provide protocol guidance and coinholder polling services 1.

Winklevoss Asset Services filed a Form S-1 registration statement with the US Securities and Exchange Commission on October 6, 2026, to launch a spot Zcash exchange-traded fund 1. The proposed fund, named the Winklevoss Zcash ETF, plans to list its shares on the Nasdaq Stock Market under the ticker symbol WINK 1.

According to the prospectus, the trust intends to offer direct exposure to the price of $ZEC, net of operational expenses and liabilities 1. Gemini Trust Company, an affiliate of the sponsor, will act as the custodian responsible for holding the trust's underlying ZEC 1. CSC Delaware Trust Company is named as the trustee 1. Net asset value determinations will rely on a pricing benchmark derived from a 60-minute time-weighted average price across constituent spot exchanges 1.

Structure and Ecosystem Advisory

The trust plans to issue and redeem shares in continuous blocks known as baskets through authorized participants, utilizing cash or physical ZEC 1. The fund is structured as a grantor-style trust under the Securities Act of 1933 rather than an investment company registered under the Investment Company Act of 1940 1.

To support governance and network integration, the trust has engaged Cypherpunk Technologies as its official "Zcash Ecosystem Partner" 1. Under the agreement, Cypherpunk will assist with technical guidance, coinholder polling, and advisory services concerning the Zcash protocol 1.

The filing marks an expansion into privacy-focused digital asset funds following prior international and domestic initiatives, such as when Valour debuted a Zcash ETP on Spotlight Stock Market in Europe. The SEC must review the registration statement before it becomes effective and trading can commence 1. At the time of writing, ZEC was trading at $1,352, up 4.3% over the prior 24 hours.
