Grayscale filed an S-3 registration to convert its Zcash Trust into a Spot Zcash ETF, with a proposed listing on NYSE Arca under the ticker ZCSH, sparking volatility and market debate over whether ZEC could break above the $600 threshold. Dated November 26, 2025, the filing blends institutional momentum with uncertainty surrounding privacy-asset compliance. The submission places Zcash in the center of the ETF conversation for the first time at spot level.
Custody architecture, ETF structure and regulatory friction
The S-3 indicates that Coinbase Custody will hold ZEC, Coinbase will serve as prime broker, and BNY Mellon will operate as transfer agent and administrator. Grayscale notes that the ETF will not allow in-kind creation or redemption during its initial phase, reflecting risk containment while regulatory frameworks for privacy-assets continue to evolve.
We’ve filed the ZCSH Form S-3 – an important step required to launch the first ZEC ETPs.
Zcash launched in 2016. Seeing the potential of the Zcash protocol, we launched Grayscale Zcash Trust (Ticker: ZCSH) as a private placement in 2017.

ZEC traded near $543 on November 27, 2025, with support zones recognized at $480–$520 and resistance forming at $600, a level many see as technically pivotal. Analysts argue that a daily close above $600 could open targets at $640 and $748, although this remains speculative and contingent on liquidity. The recent OKX relisting added upward pressure, reinforcing near-term sentiment.
Core dilemma: privacy cryptography vs ETF transparency
Zero-knowledge proofs validate transactions without revealing inputs, a defining Zcash feature. This cryptography is both ZEC’s value and its regulatory tension point — privacy preserves user confidentiality, yet ETF reporting obligations demand traceability, AML/KYC compatibility and supervisory visibility. Previous delistings by exchanges for privacy reasons underscore heightened compliance risk versus transparent assets like BTC or ETH.
The ETF structure may improve access for treasuries and asset managers, but does not neutralize volatility or underlying asset risk. The absence of in-kind functionality can widen NAV/spot divergence during stress events, affecting liquidity quality. Treasury desks evaluating exposure must weigh fees, custody counterparties, creation mechanics, and spread behavior.
In derivatives markets, greater institutional focus could lift OI in futures and perpetuals, altering funding dynamics and demanding tighter leverage management around key levels — 520, 600, 640 and 748. Risk desks should stress-test for high slippage in thin phases.
Grayscale’s S-3 filing marks a milestone toward mainstreaming a privacy-preserving cryptocurrency, but its outcome depends on regulatory treatment and the capacity to harmonize custody, transparency and compliance. A breakout above $600 would validate momentum, not guarantee sustainability.
