Zcash has completed a two-phase emergency network upgrade to fix a critical 
vulnerability in its Orchard shielded pool — a flaw that sat undetected for 
four years, could theoretically have allowed unlimited undetectable 
counterfeit ZEC creation, and triggered a 50% price collapse before the 
network&#8217;s swift response began restoring confidence and driving a recovery in 
ZEC&#8217;s price. Related Reading: Analyst Charts Ethereum Long-Term Roadmap To 
$16,000 – There’s No Need To Panic Josh Swihart, CEO of Electric Coin Company 
— the primary developer of Zcash — posted on X on June 7 confirming the fix 
was complete and the network secure, as ZEC began its recovery from the lows 
reached after the vulnerability&#8217;s disclosure. The post arrived at a critical 
moment for the asset: ZEC had crashed approximately 50% from a June 4 peak of 
$624 to $309 on June 5, wiping more than $3 billion from its market 
capitalization, per the BitMEX Blog&#8217;s documented timeline of the incident.

Was The vulnerability was discovered on May 29, 2026 by security researcher 
Taylor Hornby during a protocol audit commissioned by Shielded Labs. Hornby 
identified a &#8220;soundness&#8221; flaw in Zcash&#8217;s Orchard zero-knowledge proof circuit 
— specifically an under-constrained element in the Orchard Action circuit that 
could allow invalid state transitions, creating a theoretical double-spending 
risk within the shielded pool. The discovery was made using Anthropic&#8217;s Claude 
Opus 4.8 AI model alongside a custom analysis suite, per Shielded Labs&#8217; 
official disclosure. Hornby and the AI developed a working proof-of-concept 
that successfully generated unlimited, completely undetectable counterfeit ZEC 
in a local test environment — described by one independent analyst as &#8220;about 
the worst kind of bug a cryptocurrency can have,&#8221; per Yahoo Finance&#8217;s 
reporting of the disclosure. Critically, the flaw did not permit inflation of 
the total ZEC supply on the live network. Zcash&#8217;s internal turnstile 
accounting mechanism — which tracks the total value moving into and out of the 
shielded pool — confirmed no unauthorized value creation occurred while the 
flaw was active, per Shielded Labs&#8217; official statement. However, the 
organization acknowledged directly that due to the privacy properties of 
Orchard and the nature of the bug, there is no definitive cryptographic way to 
determine whether exploitation occurred — a limitation inherent to the 
shielded pool&#8217;s design that became its own source of market concern. The 
vulnerability had been present since Orchard&#8217;s activation in May 2022 — four 
years — without detection. The Emergency Response Zcash&#8217;s development 
ecosystem responded with unusual speed. The first phase was an emergency soft 
fork deployed through Zebra 4.5.3, activated at block 3,363,426 on June 2, 
which temporarily disabled all Orchard transactions to remove the attack path 
while developers prepared the permanent fix. Transparent and Sapling 
transactions continued operating normally throughout, per the Zcash 
Foundation&#8217;s official announcement on X. The second phase arrived on June 3 
through the NU6.2 hard fork — activated at block 3,364,600 via Zebra 5.0.0 — 
which introduced a corrected circuit and a new verifying key, patching the 
flaw and re-enabling Orchard transactions, per the Foundation. The market&#8217;s 
initial reaction to the hard fork was positive. ZEC rose from $544 on June 2 
to $603 on June 3, continuing to $624 on June 4 — its highest level since the 
rally began. Then Arthur Hayes publicly disclosed he had exited his entire ZEC 
position intraday on June 4 — the same day as the peak — citing five macro 
factors including higher energy prices and upcoming AI IPOs, per his X post 
covered in prior reporting. The combination of Hayes&#8217; exit and lingering 
uncertainty about whether exploitation had occurred before the patch sent ZEC 
to $309 on June 5. The Recovery And What It Means Swihart&#8217;s June 7 X post — 
reassuring the community that total ZEC supply remained intact throughout and 
that the network had passed through the emergency without confirmed 
exploitation — appears to have been the catalyst for the recovery now 
underway. The swift two-phase response, combined with the Foundation&#8217;s 
transparent disclosure and Swihart&#8217;s direct communication, provided the 
confidence signal the market needed. This development marks a pivotal and 
genuinely uncomfortable moment for Zcash&#8217;s long-term positioning in the 
nascent sector. A four-year-old vulnerability in the Orchard pool — the very 
component that defines ZEC&#8217;s core privacy value proposition — has been fixed 
cleanly and without confirmed exploitation. Related Reading: Has The Bitcoin 
Price Crash Ended Or Is This Just The Beginning? Analyst Answers But the 
structural irony that the privacy properties that make Zcash valuable also 
make it impossible to confirm the vulnerability was never used will remain a 
question mark the community will need to address as the recovery continues. As 
of this writing, ZEC trades at around $430, recovering from its June 5 lows as 
confidence in the network&#8217;s security response gradually rebuilds. Cover image

XRP and much of the broader crypto market managed a short-lived bounce on 
Monday after last week’s sharp drop to around $1.04. The recovery, however, 
comes with fresh cautions hanging over the token. Alex Carchidi, expert from 
The Motley Fool, argues that two important XRP-related metrics have turned 
notably bearish over the last 30 days. If the situation does not improve soon, 
he warns, it could undermine the argument that XRP is the “go-to” way to gain 
exposure to institutional activity in the tokenization market. Two Bearish 
Signals Emerge Carchidi points first to the XRP Ledger’s (XRPL) role in 
tokenized assets. He notes that the chain is holding about $384.5 million in 
tokenized assets, which is down 11% over the 30 days ending on June 5. Just as 
importantly, Carchidi says this breaks a prior stretch in which the value of 
tokenized assets on the network had been rising more steadily. The decline is 
not happening in isolation either. Alongside the drop in tokenized asset 
value, XRPL’s share of the overall tokenized-asset market has slipped to just 
over 1%, while tokenization activity on other chains appears to be picking up 
pace. Related Reading: XRP To $1 Or A Violent Reversal? Analyst Says Liquidity 
Setup Is Flashing The second metric Carchidi highlights is even more 
concerning. According to his report, the XRPL’s 30-day tokenized asset 
transfer volume has fallen 59% to roughly $54.1 million. In his view, this is 
the kind of slowdown that matters because inactive or stagnant tokenized 
assets don’t generate the economic “motion” that a blockchain ecosystem 
depends on. Carchidi argues that when tokenized assets stop moving, it 
suggests asset managers may be holding positions rather than deploying capital 
to generate yield. Conditional Warning For XRP Carchidi frames the issue in 
practical terms. If tokenized assets are not being transferred, he says the 
network’s economy is not demonstrating its value, which can weaken the bullish 
case for XRP in the tokenization narrative. In other words, the problem isn’t 
simply that tokenized assets are lower in value—it’s that the activity 
associated with those assets appears to be fading. Still, Carchidi also 
acknowledges that the picture is not uniformly bleak. He points to growth in 
other parts of the XRPL ecosystem during the same 30-day window. Specifically, 
real-world asset (RWA) holders on the XRPL rose 275%, bringing the total to 
105 holders. At the same time, stablecoin transfer volume increased by 118%, 
reaching $4.5 billion. That contrast, Carchidi suggests, indicates that 
capital is still flowing through the network, just not as much through the 
tokenized asset pipeline that investors watch most closely. Because of that, 
he does not present the decline in tokenized asset transfer volume as an 
immediate “fire alarm.” Related Reading: Ripple Partner Bank of America 
Unveils Global Payments Expansion Strategy His warning is conditional: if 
tokenized asset metrics continue to shrink over the next quarter or 
so—especially if outflows accelerate or volume falls even faster—then the 
bullish thesis for XRP tied to tokenization institutional positioning could 
face a serious credibility problem. For now, the recovery after $1.04 to 
current trading levels around $1.18 may be a step up for sentiment, but the 
broader tokenization indicators remain the key question for what happens next.
