The Winklevoss twins are now setting their sights on Zcash. Their firm Winklevoss Asset Services has filed for a Zcash spot ETF under the ticker WINK, with custody designated to its own exchange Gemini and a management fee set at 0.25%.

This isn't the first time a Zcash spot ETF has shown up on the filing list. Grayscale already has a similar product out under the ticker ZCSH, and if WINK gets approved, it'll be competing directly with ZCSH for market inflows. The difference this time is that Winklevoss is keeping custody in-house—Gemini serves as both the exchange and the custodian, meaning the entire product line, from filing to safekeeping, stays under one roof within the same group.

For now, public information is limited to the filing stage, with no approval timeline or listing date announced yet.
