The fund converts a nine-year-old Grayscale trust holding roughly 390,000 ZEC and charges 2.50% a year, with the fee revenue routed back into Zcash development.
Grayscale's Zcash fund began trading on NYSE Arca on Tuesday under the ticker ZCSH, the first US exchange-traded product offering spot exposure to ZEC. The product itself is not new. It has run as a private placement since October 2017, and Grayscale filed with the Securities and Exchange Commission last November to convert it into a redeemable exchange-traded product. What changed this week is the audience.
Three months ago, Zcash was dealing with the possibility that its money supply was a fiction.
In May, the security researcher Taylor Hornby used Anthropic's Claude Opus 4.8 to surface a four-year-old bug in Orchard, the shielded pool where private Zcash transactions settle. The flaw would have allowed an attacker to mint counterfeit ZEC. Developers shipped an emergency patch on 1 June, and then ran into the part no patch could reach: because Orchard conceals transaction amounts by design, nobody could establish cryptographically whether the bug had ever been exploited. The property that gives Zcash its reason to exist is the same property that made its own supply unauditable. That has been the trade-off since the network launched in October 2016 as the first cryptocurrency to ship zero-knowledge proofs at scale, but it had never before been tested against a live counterfeiting question.
The answer arrived in July with the Ironwood upgrade, which retired Orchard in favour of a new shielded pool and imposed an accounting rule at the protocol level: no more ZEC may leave the old pool than went into it. Any counterfeit coins that exist are trapped where they were made. This is competent engineering and an honest admission at the same time. The developers could not prove the supply was clean, so they built a wall around the part they could not see.
This is the asset Grayscale now sells through brokerage accounts at 2.50% a year.
That fee is roughly eighteen times the 0.14% Morgan Stanley priced its ether and solana products at last month, and two-thirds higher than the 1.5% Grayscale held on its Bitcoin trust after conversion in January 2024 — a decision that cost it $8 billion of outflows in two months as cheaper rivals took the flows. ZCSH faces no such competition. It is the only listed spot ZEC product in the country, and 2.50% holds until somebody files against it. Grayscale says the fee revenue will be directed back into Zcash network development, which makes the sponsor a funder of the asset it sponsors.
The trust held roughly 390,000 ZEC going into the conversion, worth more than $260 million as of Friday. Steve Vanourny, Grayscale's head of index, told Decrypt the firm sees ZCSH as "a focused, higher-risk satellite position within a broader digital-asset allocation that is complementary to, but not a replacement for, Bitcoin." He framed the pitch as Bitcoin-like scarcity, proof of work and a 21 million coin cap, plus optional privacy that Bitcoin does not offer.
The scarcity half of that pitch is precisely what the Orchard bug put in doubt. Bitcoin's cap is enforceable because any node can total the unspent output set and check the arithmetic against the issuance schedule. Zcash's cap is enforceable in the transparent pool and, since Ironwood, bounded in the shielded one. Bounded is not counted. Someone buying ZCSH is buying a supply guarantee that rests on a fence rather than a ledger. That is a defensible thing to own. It is not the same thing as owning bitcoin, whatever the proof-of-work similarities suggest.
ZEC traded above $850 in the run-up to the listing, its strongest level since early 2018, and had slipped to around $765 by Wednesday morning. Grayscale did not choose the price. But converting a nine-year-old trust in the same week its underlying asset prints a multi-year high hands new shareholders an entry at the top of a rally they were not around for, and the private-placement holders who were around for it now have a redemption mechanism they lacked.
Altcoin funds have had a thin year in the US. One fund holds 80% of every dollar in American Solana ETFs, a concentration that says less about Solana than about how few buyers turn up for anything beyond bitcoin and ether. Grayscale's wager is that privacy is the exception, and that advisers who would not touch a privacy coin on an exchange will hold one in a brokerage account because the wrapper makes it respectable.
Vanourny said Grayscale will judge the network by adoption, utility and network security rather than price, and named the Ironwood rollout as what it is watching most closely. That upgrade exists because the shielded pool at the centre of Zcash's entire proposition spent four years carrying a flaw nobody had found.
