On May 12, 2026, a major development unfolded in the crypto investment space: Grayscale submitted a Form S-3 to the SEC, aiming to transform its existing Zcash Trust into a spot exchange-traded fund (ETF) under the ticker ZCSH on NYSE Arca. This move could mark the first U.S. spot ETF for a privacy-focused cryptocurrency, opening doors that were previously closed due to regulatory uncertainty.
The filing comes on the heels of the SEC’s decision in January 2026 to close its investigation into the Zcash Foundation without taking any enforcement action. That probe had cast a long shadow over Zcash since August 2023, creating ambiguity about whether the token might be classified as an unregistered security. With that overhang removed, Grayscale saw an opportunity to advance a regulated product for institutional investors.
The Zcash Trust currently holds approximately 391,103.89 ZEC, valued at around $99.4 million as of March 31, 2026. Coinbase Custody will manage the underlying tokens, while BNY Mellon handles administrative duties. The fund will track the CoinDesk Zcash Price Index. If approved, analysts project inflows between $500 million and $2 billion, which could represent a substantial portion of ZEC’s roughly $6 billion market cap.
What makes this filing unique is not just the asset class but the mechanics. Grayscale is using the same Form S-3 conversion pathway that successfully turned its Bitcoin and Ethereum trusts into spot ETFs in 2024. However, the Zcash product is significantly smaller—about one-thousandth the size of the Bitcoin trust at conversion. This smaller scale means initial trading may be less dramatic, but the precedent it sets for privacy coins is enormous.
The regulatory timeline is also noteworthy. Under new SEC generic listing standards adopted in late 2025, the review period for crypto ETFs has shrunk from 240 days to roughly 75 days. This means a potential approval could come as early as Q3 2026, assuming no major hiccups.
A critical detail is that the ETF will hold ZEC in transparent addresses at Coinbase Custody, not in shielded addresses that provide privacy. This is because Coinbase’s infrastructure currently supports only transparent transactions for Zcash. As a result, the fund’s holdings will be visible on-chain, creating an interesting tension: the ETF’s value proposition depends on privacy adoption, but the ETF itself does not use privacy features. Institutional investors buying ZCSH shares get exposure to ZEC’s price movements without directly benefiting from its privacy capabilities.
The SEC’s January probe closure was a key enabler, but it does not resolve all regulatory risks. Privacy coins remain under scrutiny from other agencies like FinCEN and OFAC for anti-money-laundering concerns. However, for the specific purpose of a securities-based ETF, that closure was the major hurdle.
Looking ahead, ZCSH could pave the way for other privacy-optional coins like Dash or Decred, but not for mandatory-privacy coins such as Monero, which cannot easily comply with transparent custody requirements. The filing represents a calculated bet that privacy can be a regulated asset class, and the outcome will influence crypto markets for years to come.
