Zcash ETF Announces 3-for-1 Split as NU7 Upgrade Targets November 5

• Grayscale’s Zcash ETF (ZCSH) executes a 3-for-1 forward share split to improve liquidity following robust investor inflows and significant trading volume since its August launch.
• Zcash developers unanimously target November 5 for the NU7 mainnet upgrade, which reduces block times from 75 to 25 seconds and integrates a network sustainability mechanism.
• A heavily leveraged short position in ZEC recently incurred a $7.66 million unrealized loss as the asset rallied toward $1,500, highlighting extreme volatility.
• Community governance polls overwhelmingly support preserving scheduled halvings and delaying recycled ZEC until 2031.

Grayscale has announced a 3-for-1 forward share split for its Zcash ETF (ZCSH) less than one month after the fund's debut on the NYSE Arca. Shareholders of record at market close on September 28 will receive three shares for every pre-split share held, with additional shares distributed after the September 29 close. Split-adjusted trading begins before the market opens on September 30. The fund retains its ZCSH ticker and existing CUSIP number, ensuring the split does not alter any shareholder's total investment value .

Investor demand has been robust since the fund's August 25 launch. The ETF has attracted over $233 million in cumulative inflows, with daily inflows reaching $112 million on September 8 and approximately $46.6 million on a recent Wednesday. By mid-September, the fund held roughly $890 million in net assets and exceeded $11 billion in cumulative trading volume .

The ETF's success coincides with a significant rally in ZEC, which traded near $1,450, up approximately 24% over seven days. This price appreciation has intensified network competition, with estimated solrate rising from 25 GSol/s to nearly 32 GSol/s. Mining difficulty has also climbed to a network record of approximately 291 million, strengthening network security but reducing individual miner rewards as computing power increases .

What Is the NU7 Mainnet Upgrade Timeline?

Zcash developers have reached a unanimous agreement to target November 5, 2026, for the NU7 mainnet upgrade. This schedule follows a testnet rollout on October 6 and a final go/no-go decision on October 20. The upgrade centers on three core technical changes: reducing block spacing to 25 seconds under ZIP-218, disabling v4 transactions, and integrating the Network Sustainability Mechanism via ZIP-234 (alt) and ZIP-235 .

The timeline was finalized after discussions among the Zcash Foundation, Project Tachyon, Valar Group, ZODL, and Shielded Labs. Code completion is scheduled for September 30, allowing two weeks for testnet performance review. The official testnet will activate NU7 on October 6, giving developers time to assess performance before the mainnet decision .

Poll results indicate community support for preserving the existing halving schedule, with the reintroduction of previously removed supply starting in February 2031. The upgrade does not introduce new transaction formats, minimizing impact on wallets. However, full nodes, indexers, and block explorers may require updates to handle the higher block frequency. The November 5 date remains a target; a consensus mismatch or infrastructure failure during testing could delay activation .

How Are Market Participants Reacting to the Rally?

A Zcash trader recently incurred a $7.66 million unrealized loss after taking a heavily leveraged short position during ZEC's rally. The trader, who previously achieved an 89% win rate across 47 trades with over $9 million in profits, opened a 12,285 ZEC short worth approximately $18.3 million at an average price of $867. With ZEC nearing $1,486, the position faces liquidation if prices reach $1,551 .

The rally was driven by structural changes, including a governance vote that reduced block-target spacing from 75 to 25 seconds, which analysts argued supported continued growth. Additionally, on-chain data revealed newly created wallets withdrawing tens of millions of dollars in ZEC from exchanges, tightening supply. This supply shock contributed to ZEC climbing 200% over 30 days and nearly 2,800% year-over-year .

The event underscores the fragility of leveraged positions in fast-moving markets. Over $32.7 million in ZEC positions were liquidated in 24 hours, with shorts accounting for $27.17 million. Similar large-scale short squeezes have affected other traders, including one facing $26 million in paper losses on a $51.5 million short .

Zcash's recent rally is largely attributed to a narrative reset by investor Naval Ravikant, who framed ZEC as insurance against Bitcoin. This positioning resonated as AI capabilities advanced from simple chatbots to reasoning models, raising concerns about financial surveillance. Public blockchains leave permanent trails that AI and large language models can now exploit to link on-chain data with off-chain identities, shrinking anonymity sets dramatically.

However, on-chain metrics present a mixed picture. Shielded pool supply, a key indicator of actual privacy usage, rose sharply in early 2025 but stagnated through much of 2026. The latest price breakout above $1,000 appears driven more by narrative acceleration than by a surge in shielded usage. Despite this, Zcash has demonstrated resilience against negative events, such as the resignation of the Electric Coin Company team and the disclosure of a critical Orchard pool bug .

Zcash holders have voted overwhelmingly to preserve the network's scheduled halvings and defer the recycling of collected ZEC until February 2031. The results come from a five-question poll on NU7, with participation ranging between 2.399 million and 2.404 million ZEC per question . The largest monetary-policy result concerned whether the Network Sustainability Mechanism should replace periodic halvings with a smoother issuance curve. The final tally placed 2,375,932.375 ZEC behind preserving halvings, compared to just 22,384.875 ZEC for smoothing issuance .
