Winklevoss twins file S‑1 for spot Zcash ETF on Nasdaq

Winklevoss Asset Services submitted an S‑1 registration on Oct 6, 2026 to launch a spot Zcash exchange‑traded fund that would list on Nasdaq under the ticker WINK. The fund would hold ZEC directly, with Gemini Trust as custodian, and would charge an annual sponsor fee of 0.25%. Winklevoss Capital Fund has indicated a non‑binding interest to purchase up to $100 million of shares, while Grayscale’s existing Zcash ETF holds roughly $751 million in net assets.

If approved, the WINK ETF would give investors regulated exposure to Zcash at a fee ten times lower than Grayscale’s 2.5% charge, potentially drawing assets from the larger fund. The filing also flags a recent security flaw in Zcash’s Orchard pool as a risk, which could affect investor sentiment toward privacy‑coin products.
