ZEC got back into focus after the Zcash team revealed an issue affecting Orchard and rolled out the NU6.2 update to address it. Traders followed the story closely because Orchard is part of Zcash’s privacy system, and any problem tied to shielded transactions tends to attract extra scrutiny.
XMR was mentioned alongside the news when the researcher who identified the Zcash issue said Monero was next on his list for review. There have been no reports of a similar problem in Monero, but the announcement was enough to put the broader privacy-coin market on watch.
In this article, we break down what happened with Zcash, why it mattered to investors, how ZEC and XMR responded, and what traders are paying attention to after the latest security-related developments in the privacy-coin space.
Latest ZEC News On The Orchard Security Update
The Orchard update carried the latest ZEC news because it touched shielded activity and supply integrity. Zcash paused affected Orchard actions, shipped NU6.2, and brought Orchard back with corrected circuit logic.
What Zcash Fixed
Zcash Foundation called the issue a critical soundness vulnerability in the Orchard zero-knowledge proof circuit.
Taylor Hornby caught the issue on May 29 during a Zcash protocol audit for Shielded Labs. ZODL engineers checked the report the same day and confirmed the problem within hours.
Zcash handled the fix through two Zebra releases.
Zcash addressed the issue through two Zebra updates. In its disclosure, the project said the first release "temporarily disabled Orchard actions" as a precaution, while the second "activated NU6.2" and restored Orchard functionality with the corrected circuit.
Orchard resumed operating with the corrected circuit.
Why Orchard Hit The Market Harder
Orchard is a shielded pool. Traders could not simply open an explorer, check flows, and calm down. With shielded activity, part of the picture stays hidden by design.
For ZEC traders, the questions weren't complex at all:
could total supply still be trusted;
would liquidity thin out;
would spreads widen;
would exchanges pause deposits or withdrawals;
would official updates calm the market.
Supply Integrity And Claude
According to Zcash Foundation, successful exploitation could have allowed invalid state transitions and possible double-spending inside Orchard.
The same update said the turnstile mechanism protected total ZEC supply, with no evidence of exploitation, unauthorized value creation, or privacy impact.
CoinDesk reported that Hornby used Anthropic’s Opus 4.8 model during the review. Claude supported the audit workflow; the finding still came through human-led security work.
Zcash comes through this block through execution: the issue was found, confirmed, disclosed, paused, and fixed.
XMR Monero Security Audit Watch With No Vulnerability Reported
Monero became part of the story for a different reason. After the Orchard disclosure, traders were already paying closer attention to privacy coins, so security-related headlines carried more weight than usual.
CoinDesk announced that Taylor Hornby, the researcher behind the Zcash finding, had added Monero to his audit queue.
On most days, that would be a fairly ordinary part of security research. Coming right after the Orchard news, it put XMR on a lot more traders’ screens.
Why XMR Entered The Watchlist
As CoinDesk reported Hornby’s comment about adding Monero to his audit queue and noted that his Zcash review used Anthropic’s Opus 4.8 model.
On a quiet week, nobody panic-sells an audit queue. After the Zcash disclosure, the tape was already twitchy. Traders saw the same researcher, another privacy coin, and a fresh security review. XMR did not need a confirmed flaw to get watched harder.
XMR And ZEC Price Reaction
XMR traded around $321 at the time of writing, with an intraday range near $310–$329 while ZEC had already bounced from its intraday low near $428 and traded around $470 after the Orchard fix.
The price action was messy, but the logic wasn’t. Primarily, the privacy traders checked the exits, like liquidity, spreads, deposits, withdrawals, and exchange behavior.
The full technical read came later.
What Traders Took From XMR
An audit queue deserves attention; exploit-level panic needs proof. Zcash had already closed the known Orchard issue, but the disclosure made traders look at the whole privacy stack with less trust and more speed.
Shielded pools, supply integrity, liquidity, and exchange access stopped being background details. For a few hours, they were the trade.
ZEC price news moved from panic to post-fix trading once traders had official facts to work with. The first reaction centered on exits, spreads, deposits, withdrawals, exchange status, and liquidity after NU6.2 activation.
Search interest around “why is Zcash dropping” made sense during the first reaction. Later price action had more to trade on: a completed network fix, official supply-integrity statements, and exchange service updates.

Reddit captured the retail split after the Orchard update. Here we can see how traders and users react to the situation.
Panic posts focused on the word “critical”; calmer comments pointed to due diligence, the turnstile mechanism, patches, and the completed fix.

Red Flags Traders Watch After Privacy Coin Security News
Privacy-coin security news hits the market in a very specific way.
Price gets loud first, but experienced traders look at the boring stuff before joining the panic.
A single signal rarely carries the whole story. Audit queue deserves attention. Exploit talk needs proof. Network maintenance needs a real notice from the team or exchange. A selloff can mean thin bids, stressed liquidity, or traders rushing for exits.
After the Orchard update, traders had a reason to watch privacy coins more carefully.
The smart move stays boring: read official updates, check exchange access, watch spreads and liquidity, then decide if the market is pricing facts or just feeding itself fear.
What Not To Overread And How To Save Your Nerves
Audit queue deserves context, exploit talk needs proof, network maintenance needs a real notice, and a selloff can come from thin bids or stressed liquidity before it says anything about the protocol itself; taken together, these signals explain why traders check privacy coins harder after security news.

Conclusion
Don’t let panic posts steer your strategy; stick to confirmed updates, check exchange access and liquidity, and keep a cold head before making a move.
For ChangeNOW, stories like this are worth watching because they often shape user behavior faster than price does. A protocol update can turn into questions about routes, asset availability, and market confidence within hours.
The Orchard disclosure felt like one of those moments.
