Winklevoss Asset Services has submitted a registration statement to the US Securities and Exchange Commission for a spot Zcash exchange-traded fund. The proposed investment vehicle would maintain direct holdings of ZEC tokens and pursue a Nasdaq exchange listing with the ticker symbol WINK.
The application was submitted via an S-1 registration document. According to the filing, the fund structure excludes futures contracts and derivative instruments, relying instead on physical token holdings to mirror ZEC price movements.
Gemini Trust Company has been designated as the digital asset custodian for the fund. The creation and redemption mechanism will operate exclusively through cash transactions conducted by authorized participants.
Proposed ETF Structure and Operations
The filing outlines a framework where Gemini maintains custody of the underlying ZEC tokens that correspond to outstanding ETF shares. Authorized participants would engage in share creation and redemption processes using only fiat currency.
Winklevoss Asset Services would subsequently execute spot market trades for ZEC tokens as needed to maintain the fund’s target exposure. This operational model provides investors with direct economic exposure to Zcash price movements through a regulated securities wrapper.
The registration document also identifies Cypherpunk Technologies as an entity providing services related to the Zcash blockchain network. This designation is distinct from Gemini’s custodial responsibilities.
Importantly, the filing submission does not grant immediate trading authorization. The investment product requires explicit SEC approval before shares can be offered to the public on an exchange.
Cypherpunk Technologies had already established a significant presence in the Zcash ecosystem prior to this ETF filing. The Nasdaq-listed firm announced in August that it had acquired mining infrastructure and associated hosting agreements for Zcash operations.
The transaction carried a total value of $33.33 million and involved entities with connections to Winklevoss Capital. The acquisition included a fleet of Bitmain Z15 Pro mining machines operating at facilities within the United States.
According to Cypherpunk’s assessment, the acquired hardware represented approximately 18% of the total computational power securing the Zcash network. The company projected monthly production of roughly 7,800 ZEC tokens, subject to variations in network difficulty and competitive dynamics.
The purchase was structured through a pre-funded warrant instrument covering 43,290,042 common shares. These shares carried a valuation of $0.77 per unit with a nominal exercise price of $0.001.
Token Performance and Upcoming Network Upgrade
ZEC experienced upward price momentum exceeding 5% during the 24-hour period following the ETF filing announcement, reaching levels above $1,375 based on CoinMarketCap data. The broader cryptocurrency market registered gains approaching 1% during the comparable timeframe.
The privacy-focused token advanced from approximately $1,290 to $1,350 before experiencing a retracement to the $1,320 range. Subsequent buying pressure pushed prices back toward the $1,380 level.
Technical analysis of recent price action identified resistance zones in the $1,375 to $1,380 range. Support levels appeared established near $1,355 to $1,360, with secondary support observed around $1,340 to $1,345.
The planned NU7 protocol upgrade includes a significant modification that would reduce the target block time from 75 seconds to 25 seconds. Despite the faster block production schedule, daily ZEC issuance rates would remain unchanged due to a proportional reduction in per-block rewards.
The upgrade specification also includes the deactivation of version 4 transaction formats at the moment of activation. This technical change would prevent future spending from the legacy Sprout shielded pool, as version 5 transactions lack backward compatibility with that older privacy architecture.
The Zcash development team has established October 20 as the decision date for determining the mainnet activation block height for NU7. The targeted launch date of November 5 remains contingent upon successful completion of testnet evaluation and community consensus.
