Winklevoss Twins Target Nasdaq with Spot Zcash ETF Filing
Winklevoss Asset Services has submitted an SEC filing to launch a spot Zcash ETF backed by a potential $100 million seed commitment.

Winklevoss Asset Services has officially registered with the U.S. Securities and Exchange Commission to launch a spot Zcash ETF aimed at trading on the Nasdaq exchange. The proposed investment product, slated to list under the ticker symbol WINK, is designed to grant investors direct spot exposure to the privacy-oriented token ZEC rather than relying on derivative contracts, according to details reported by Cointelegraph and Bitcoin.com News.
Under the proposed operational structure, Gemini Trust Company will serve as the dedicated custodian safeguarding the underlying ZEC reserves. Creation and redemption of fund shares will follow a cash-creation mechanism. Furthermore, entities affiliated with Winklevoss Capital have expressed interest in deploying up to $100 million in initial seed capital to support the fund's debut, underscoring substantial financial backing from the venture firm led by Cameron and Tyler Winklevoss.
The initiative represents an aggressive push to expand regulated exchange-traded products beyond Bitcoin and Ethereum, directly challenging established crypto trusts such as Grayscale's existing vehicles. By pursuing a full spot listing for an asset centered around zero-knowledge privacy technology, the sponsors are testing federal regulators' appetite for privacy coins, which have historically faced heightened regulatory scrutiny in multiple global jurisdictions.
Market observers note that the approval process carries significant hurdles, as the SEC has historically maintained stringent standards regarding market surveillance, custody compliance, and anti-money-laundering safeguards for underlying crypto networks. The classification and unique cryptographic architecture of Zcash present distinct compliance questions that regulators must navigate before granting a formal green light.
Going forward, the digital asset sector will closely track the SEC's timeline for acknowledging the submission and issuing potential feedback or statutory delay notices. Industry participants are watching whether the proposed $100 million backing and established custody framework will be sufficient to pave the way for the first publicly listed spot privacy fund on a major U.S. exchange.
