Your weekly digest of Zcash ecosystem news, protocol updates, and privacy insights. Edition #9//Top Stories
Grayscale Files World's First Privacy Coin Spot ETFGrayscale Investments submitted Form S-3 with the SEC to convert its $200M+ Zcash Trust into a physically-backed spot ETF, trading on NYSE Arca as $ZCSH. If approved, it would be the first US spot ETF for a privacy-focused cryptocurrency. Coinbase Custody serves as custodian and Bank of New York Mellon as administrator. The filing came just 48 hours after the CLARITY Act cleared the Senate Banking Committee 15–9, which provides regulatory clarity for digital commodities — a framework that benefits ZEC's positioning. Grayscale has successfully converted 10 crypto trusts to ETFs since early 2024 with a 100% success rate. The trust currently trades at roughly a 7% discount to NAV, a gap an ETF structure would close. CryptoBriefing
Zcash Hits the Wall Street Journal Front PageThe Wall Street Journal ran a major feature: "Crypto Die-Hards Think They've Found the Next Bitcoin" — profiling Zcash as the privacy coin capturing crypto's attention as users rotate out of Bitcoin into ZEC for shielded transactions. Barry Silbert told Forbes the same week that ZEC "feels like Bitcoin circa 2013." Combined with Cypherpunk ($CYPH) announcing the purchase of an additional 10,279 ZEC for $5M (~$486 average) — bringing their total holdings to ~1.88% of network supply — the institutional and mainstream narrative around Zcash has never been louder. ZEC is up over 1,100% in the past year. WSJ tweet
NU7 Coinholder Polling Launches — First In-Wallet Governance VoteJosh Swihart posted the formal NU7 sentiment poll with 6 key questions covering NSM issuance smoothing, fee reissuance timing, Sprout deprecation, memo bundles (ZIP-231), faster block times (75s→25s via ZIP-218), and the overall NU7 schedule. Community feedback is open until May 25, with the actual vote running June 10–24.
For the first time, Zcash coinholders will vote directly inside the Zodl mobile wallet — 1 ZEC = 1 vote, with MPC-encrypted ballots and publicly auditable results. ValarDragon's team built the privacy-preserving voting mechanism using PIR snapshots. Keystone hardware wallet users are also supported. This is the most significant governance milestone for Zcash in 2026. Forum · jswihart tweet (85K+ impressions)

ZODL Hires Two Engineers in 48 Hours. Danny Willems (@dwillems42), former head of cryptography at o1Labs and a known privacy researcher joined ZODL full-time. Swihart called him "a gem." Within hours, Zcash_Harry, a Cosmos and Zcash contributor, also announced he was joining ZODL. Sean Bowe (ebfull) remarked the team "feels legendary." Two high-caliber hires in one week signal a scaling ZK research bench. Danny · Harry Vizor Wallet Ships on macOS. A beautifully crafted new desktop Zcash wallet launched with day-one Keystone hardware wallet support, multi-account management, and fully open-source code (Apache 2.0). Community reception was warm, with immediate demands for Linux support and mobile apps. The launch generated 66K+ impressions — a strong debut for the desktop wallet space. Tweet Noir Wallet Previewed. A new wallet project called Noir posted its first community preview on the forum — another entry into an increasingly competitive Zcash wallet landscape. Details are still emerging. Forum ZecMap Launches Reward Program. Batuhan's merchant discovery tool launched a community reward program — users who add businesses to ZecMap earn rewards. The goal: 1,000 listed businesses by Q4 2026. ZecMap's web version is live in English and Turkish, with Android/iOS apps coming soon. Forum ZODL Summit — July Applications Open. The twice-yearly gathering of Zcash contributors and ecosystem partners returns in July. Community applications are now open. jswihart tweet CipherPay Launches In-Person Point of Sale. CipherPay shipped a PWA-based Point-of-Sale mode, enabling any merchant with a smartphone to accept shielded Zcash payments in person — no app store required. Paired with Zodl, it turns any device into a ZEC payment terminal. Combined with the WooCommerce plugin for online stores, CipherPay now covers both in-person and e-commerce flows. cipherpay.app $41M Synthetic ZEC on Solana. Swihart flagged that $41M worth of synthetic ZEC traded on Solana in a single week — and reminded users that solZEC holders have no privacy. "Swap from solZEC to shielded ZEC on Zodl for private storage." Tweet Zooko at Network State Conference. Zooko delivered a five-minute unscripted talk at the Network State conference, disclosing a private conversation between Hal Finney and himself. Cypherpunk amplified the clip, and it picked up 65+ retweets — sparking spirited debate across crypto Twitter about Zcash's philosophical lineage. @zcashesp Suspended. The Zcash en Español account (yoditar's) was suspended by X/Twitter for alleged brand impersonation. The community has rallied behind the appeal. Forum//Governance & Grants

"ZODL is gaining some really great employees! They should feel at home with such a legendary team."

//Privacy Corner: Why In-Wallet Governance Matters for Privacy
Zcash's new coinholder polling mechanism doesn't just give users a voice — it does so privately. Here's why that matters.
Traditional crypto governance (Snapshot, Tally, etc.) links your wallet address to your vote. Anyone watching the chain can see which addresses voted which way, how much weight they carry, and potentially correlate votes to real-world identities.
Zcash's approach is different. The Zodl polling system uses PIR (Private Information Retrieval) to take balance snapshots without revealing which addresses hold how much. Votes are MPC-encrypted — no single party (including ZODL) can see how individuals voted until results are published in aggregate.
Practical tip: When participating in the upcoming NU7 vote, you don't need to move your ZEC or expose your balance. Simply vote from within Zodl — your shielded balance is your ballot, and your preferences stay private. This is what governance looks like when privacy is the default, not a bolt-on.//Network Snapshot
