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

Winklevoss Asset Services submitted an S‑1 registration on Oct. 6 to launch a spot Zcash exchange‑traded fund that would list on Nasdaq with the ticker WINK. The fund plans to hold ZEC directly and use Gemini Trust Company as the custodian. The proposal sets an annual sponsor fee of 0.25% and notes that Winklevoss Capital Fund has indicated interest in buying up to $100 million of shares, though the commitment is non‑binding. The filing also highlights a June security flaw in Zcash’s Orchard pool as a risk factor.

If approved, the ETF would give investors regulated exposure to Zcash without needing to manage private keys, potentially expanding institutional allocation to the privacy coin. The low 0.25% fee positions the product as a cheaper alternative to Grayscale’s Zcash ETF, which charges 2.5%, which could attract assets away from the existing fund (the filing notes the fee difference).
