Zcash has entered the U.S. crypto ETF race after Winklevoss Asset Services filed an S-1 registration statement with the U.S. Securities and Exchange Commission (SEC) on Tuesday. The proposed Winklevoss Zcash ETF would hold ZEC directly and seek a Nasdaq listing under the ticker WINK.
Despite the filing, on-chain analytics firm Santiment reported that social activity and trading volume remained muted on the day of the submission.
Limited Market Attention Follows Filing
According to Santiment, which shared its findings in an X post, ZEC received 122 social media mentions on the filing day — only slightly above the average of 113 daily mentions recorded across the prior five weekdays. That figure remained below one-fifth of the Sept. 18 peak.
Trading activity told a similar story. ZEC trading volume reached $835 million, its lowest weekday reading in a month, even as the token's price rose about 2% on the day. The price nonetheless remained roughly 17% below its Sept. 26 close. Captured on the filing day itself, these figures serve as a baseline reading of market attention at the registration stage — a reference for tracking how discussion and volume develop as the regulatory process moves forward.
Santiment noted that the filing generated headlines without producing a comparable rise in discussion.
Winklevoss ETF Targets Direct ZEC Exposure
The S-1 — the standard registration form sponsors use to describe a proposed security to the SEC and prospective investors — sets out a fund that would hold ZEC directly through a trust, allowing investors to gain exposure to Zcash through brokerage accounts without directly buying or holding the token. The underlying-asset approach mirrors that of spot Bitcoin and Ether ETFs. If the registration becomes effective, the fund would trade on Nasdaq under the symbol WINK.
The filing itself does not represent SEC approval. According to the preliminary prospectus, the fund would charge an annual sponsor fee of 0.25%, and its objective is to track ZEC's price, less expenses and liabilities.
Notably, Winklevoss Capital Fund has indicated nonbinding interest in purchasing up to $100 million of shares. The indication does not guarantee that any purchase will occur.
A Broader Altcoin ETF Landscape
The proposed Zcash fund joins a U.S. ETF market that has expanded beyond Bitcoin and Ethereum products. Issuers have pursued funds tied to individual altcoins and staking-enabled assets, and Zcash — a network whose design places privacy at the center of the asset, using zero-knowledge cryptography that can shield transaction details from public view — adds a privacy-focused cryptocurrency to that group.
The registration statement can still change before becoming effective, and the securities cannot be sold until the SEC declares the registration effective. Santiment's data showed that ZEC activity remained subdued around the filing, and the proposed WINK listing remains subject to the regulatory process, with no confirmed trading date.
