Grayscale's Zcash ETF Debuts on NYSE Arca Following Fix for Major Privacy Bug

Grayscale's Zcash exchange-traded fund started trading Tuesday on NYSE Arca, becoming the first exchange-traded product to offer spot exposure to Zcash. The fund trades under the ticker ZCSH and is designed to let investors follow ZEC's price through standard brokerage accounts without directly buying or custodying the token. ZCSH traces its roots to the Grayscale Zcash Trust, launched in October 2017. Grayscale filed with the U.S. Securities and Exchange Commission in November to convert the trust into an ETF. As with other Grayscale products, shareholders hold fund shares meant to reflect the value of the vehicle's ZEC holdings rather than owning ZEC outright. Steve Vanourny, Grayscale's head of index, said Zcash's maturity, privacy features and growing demand for crypto exposure beyond Bitcoin and Ether helped support the listing. He added that the ETF is expected to primarily attract self-directed and advised investors looking for ZEC exposure via brokerage platforms. Vanourny framed ZCSH as a focused, higher-risk satellite allocation intended to complement Bitcoin rather than replace it, combining Bitcoin-like scarcity and proof-of-work economics with optional privacy. The launch follows a high-profile security episode disclosed earlier this year. In May, security researcher Taylor Hornby said he used Anthropic's Claude Opus 4.8 to identify a four-year-old vulnerability in Zcash's Orchard shielded pool that could have enabled counterfeit ZEC creation. Developers issued an emergency patch on June 1. Because of Zcash's privacy design, it was not possible to cryptographically determine whether the flaw had been exploited. Zcash activated the Ironwood upgrade in July, retiring Orchard and replacing it with a new shielded pool. The upgrade introduced accounting rules that prevent more ZEC from exiting the retired pool than entered it, effectively trapping any counterfeit coins that may exist. Vanourny said Grayscale will evaluate Zcash based on adoption, utility and network security rather than token price. He said the firm will track the rollout and uptake of Ironwood, which closed the shielded pool implicated in the June 2026 incident and added independently audited, formally verified supply guarantees. Grayscale will also watch exchange support and regulatory treatment of Zcash and privacy-focused assets more broadly.
