ZCSH began trading on August 25 after the conversion of the Grayscale Zcash Trust, a product that dates all the way back to October 2017. Investors are therefore not looking at an entirely new pool of assets. Grayscale has taken an existing vehicle and moved it into an exchange-traded structure.

The SEC prospectus describes a trust that holds ZEC and aims for its shares to reflect the value of those holdings, minus expenses and liabilities. Shares can be created and redeemed in 10,000-share baskets through authorized participants, including through transactions involving ZEC as well as cash orders.

The ETF provides Zcash exposure, not Zcash privacy

For brokerage investors, the appeal is straightforward. ZCSH removes the need to buy tokens directly, choose a wallet, secure keys or interact with Zcash's shielded transaction system.

It also means the investment experience has little to do with the technology that makes Zcash unusual. Shareholders own interests in the trust rather than ZEC in their own wallets. Coinbase Custody Trust Company holds the crypto assets, Coinbase serves as prime broker and BNY Mellon handles administration and transfer-agent duties.

That separation is worth keeping in mind as Grayscale markets privacy as part of the investment thesis. ZCSH can track the economics of ZEC without giving its shareholder the transactional privacy features of ZEC.

A 2.5% annual fee comes with the convenience

The sponsor fee is 2.5% per year. Grayscale told The Block that revenue generated by the fee will be directed back toward the Zcash ecosystem to support the network and broader development.

It is still a substantial recurring charge. A brokerage wrapper removes several operational headaches associated with owning crypto directly, but investors pay for that structure every year they remain in the product.

The predecessor trust held more than $313.5 million in assets under management immediately before the ETF launch, according to Grayscale figures reported by The Block.

The conversion also changes an old trust problem

Grayscale's earlier structure could trade at significant premiums or discounts to the value of the ZEC held by the trust. Its SEC filings show just how wide that gap became at different points in the product's history.

The exchange-traded structure introduces ongoing creations and redemptions that are intended to give market participants an arbitrage mechanism when the share price drifts away from net asset value. That does not guarantee perfect tracking, but it changes the mechanics substantially from the old closed structure.

ZEC itself had already surged before the listing. The Block measured a roughly 45% gain over the days surrounding Grayscale's final push toward launch, while Decrypt reported that the token briefly touched $888 on August 24, its highest price since 2018.

There is one final technical distinction hiding behind the familiar ETF label. According to the prospectus, the trust is not registered as an investment company under the Investment Company Act of 1940. Investors therefore do not receive all of the protections associated with shares in a conventional registered investment company.
