The Winklevoss Zcash ETF is a proposed spot exchange-traded fund sponsored by Winklevoss Asset Services, LLC, which is wholly owned by Winklevoss Asset Services Holdings. The fund is organized as a Delaware statutory trust and would hold Zcash (ZEC) directly. It has applied to list on Nasdaq under the ticker WINK. Winklevoss Capital Fund has said it may buy up to $100 million of shares, though this is not binding. The preliminary S-1 was filed with the SEC in October 2026. The fund would be the third U.S. spot Zcash ETF filing, after Grayscale and Bitwise.

Zcash is a privacy-focused cryptocurrency that launched in 2016. It uses zero-knowledge proofs (zk-SNARKs) so users can send shielded transactions that hide the sender, the receiver and the amount, while still being checked on a public blockchain. The network supports both shielded addresses and transparent addresses, so users choose how much privacy each transaction gets. Cypherpunk Technologies will act as the trust’s Zcash ecosystem partner and advise on protocol development and coinholder polling.
