Key takeaways

• ZEC is down 45% and is now trading around $309 per coin.
• The vulnerability was fixed within days, and findings suggest that actual exploitation of the bug is unlikely.

Zcash Zcash fell sharply on Friday after researchers disclosed a critical vulnerability in its Orchard shielded transaction pool that could have theoretically enabled the creation of unlimited counterfeit tokens.

The price dropped about 45% to $309 with most of the decline occurring shortly after the security disclosure was made public.

Critical flaw found in Zcash Orchard shielded pool

The vulnerability was identified by security researcher Taylor Hornby during an audit commissioned by Shielded Labs, an independent support organization for the Zcash ecosystem.

According to the report, the issue was located in the Orchard circuit, the zero-knowledge proof system that secures private transactions within Zcash’s shielded pool.

The flaw allowed under-constrained inputs in elliptic curve computations, making it possible to pass invalid values as valid proofs

In a test environment, researchers were able to generate an undetectable counterfeit ZEC. The bug has existed since Orchard’s activation in May 2022. The vulnerability was patched on June 1, shortly after discovery.

Despite the severity of the issue, Shielded Labs said there is no clear evidence that the vulnerability was exploited in the wild.

Reasons cited include: The complexity of Orchard’s privacy system obscures transaction tracing, the bug remained undetected for years despite cryptographic scrutiny, and no confirmed anomalies in supply have been identified

However, the organization acknowledged that absolute certainty is impossible due to the privacy-preserving nature of shielded transactions.

ZEC dips by 45%. Will it recover soon?

The ZEC/USD 4-hour chart is bearish and efficient as Zcash has lost 45% of its value in the last 24 hours.

The momentum indicators have flipped bearish, with the RSI of 33 indicating an oversold condition. The MACD lines are also within the negative territory, adding further confluence to the bearish bias.

If the selloff continues, ZEC could drop below the Friday low of $245 and retest the $200 pychological level.

However, the bounce back above $300 indicates that the selloff could end soon. If the bulls regain control, ZEC could surge towards the first major resistance level at $413, with further hurdles around the $527 zone.

Key takeaways

• Hoskinson clarifies social media break as ADA remains under intense selling pressure 
• ADA is down 30% this week and could extend its selloff in the near term. 

Cardano fell another 13% on Friday, bringing its weekly losses to more than 30% as investors reacted to comments from founder Charles Hoskinson and broader market weakness.

The decline marks ADA’s fifth consecutive day of losses, despite a notable increase in network activity and community engagement.

Hoskinson clarifies that he is not leaving Cardano

Market anxiety intensified after Charles Hoskinson posted a brief message on social media stating, “I’m taking a break, TTYL,” which some investors interpreted as a potential departure from Cardano and its development ecosystem.

Following the backlash, Hoskinson returned with a live broadcast to clarify that he is stepping back only from public-facing activities and social media engagement, not from his involvement in Cardano or blockchain research.

He emphasized that his focus remains on addressing complex industry challenges such as the blockchain trilemma, while distancing himself from expectations surrounding ADA’s market performance.

“I am not passionate about making the price of ADA go up,” Hoskinson stated during the discussion.

While the market reacted negatively, on-chain and social metrics suggest the Cardano community remains highly engaged.

According to Santiment data, Social dominance climbed to approximately 0.52%, the highest level recorded this year.

Furthermore, daily active addresses surged to 28,459, the strongest reading in roughly four months.

The spike indicates that discussions and network participation accelerated as investors responded to speculation surrounding Hoskinson’s comments.

However, increased activity has so far failed to offset persistent selling pressure.

Cardano price forecast: Technical outlook remains bearish

From a technical perspective, Cardano remains in a firmly bearish trend. ADA continues to trade well below its key long-term moving averages (50-week EMA: $0.4139, 100-week EMA: $0.4967, and 200-week EMA: $0.5095)

Momentum indicators also remain weak. The RSI has fallen to 22, entering oversold territory, while the MACD remains slightly positive but is nearing a bearish crossover.

These signals suggest downside momentum remains dominant despite emerging oversold conditions.

If the bearish trend persists, the next major support level sits near the 61.8% Fibonacci retracement at $0.1274, calculated from Cardano’s 2020–2021 bull market advance.

However, the $0.1500 psychological support could serve as a short-term demand level in the near term.

If the bullish trend resumes, immediate resistance would be seen at $0.2345 (50% Fibonacci retracement) and $0.4139 (50-week EMA).

A sustained break below $0.1500 would increase the risk of a deeper correction toward the $0.1274 area, while any recovery attempt would first need to overcome resistance near $0.2345 before challenging longer-term trend barriers.

Arthur Cofield, a 34-year-old Atlanta man already serving time for prior convictions, stole $11 million from a Charles Schwab brokerage account using a contraband cellphone, then escaped from a Georgia federal prison on May 26.

The case drew a wry response from David Schwartz, former Chief Technology Officer at Ripple, who wrote on X that he could not determine whether to be more shocked or impressed.

A Contraband Phone, a Stolen Identity, and 6,000 Gold Coins

Cofield was already incarcerated when federal prosecutors filed new charges against him in December 2020. He was serving time for armed robbery in Butts County, Georgia, and faced an attempted murder charge in Fulton County.

Cofield used a smuggled phone to steal the identity of a Schwab client, identified in court documents only as “S.K.” A co-conspirator supplied S.K.’s driver’s license and a utility bill. Cofield used those documents to impersonate the victim and open a checking account in their name.

Charles Schwab then wired $11 million from the victim’s account to an Idaho precious metals dealer. The funds purchased 6,106 American Gold Eagle coins. A private security firm transported the coins from Idaho to Atlanta, where they were converted into a $4 million mansion near West Paces Ferry.

He was sentenced in 2024 to more than 11 years for identity theft and conspiracy to commit wire fraud, mail fraud, and bank fraud. The court ordered him to pay restitution to the victim.

FBI Issues $10,000 Reward as Manhunt Continues

On the afternoon of May 26, authorities at the Federal Correctional Institution in Jesup found Cofield missing from the minimum-security camp. The FBI has since announced a reward of up to $10,000 for information leading to his capture. He is classified as armed and dangerous.

The story spread quickly in crypto circles. Charles Schwab is competing for crypto market share against digital-native brokers, and a fraud of this scale at the firm draws attention from the industry. The firm’s crypto custody expansion plans through 2027 have raised its profile further.

Whether Cofield is recaptured in the coming days, the scheme raises a persistent question for federal authorities. A cellphone and a stolen identity, it turns out, can go a long way.

Zcash’s native cryptocurrency, ZEC, crashed by roughly 45% today, as the market reacted to a notable disclosure from the protocol’s founder, Zooko Wilcox, and other key ecosystem figures.

The post explained that researchers had recently found and patched a critical vulnerability associated with Zcash’s Orchard shielded pool – one that could have allowed an attacker to create unlimited counterfeit ZEC without being detected.

This brought to light one of the most serious kinds of bugs a cryptocurrency could face: one that threatens the integrity of the coin’s supply.

It’s worth noting that the authors said they believe previous exploitation was unlikely; however, they also acknowledged that because of the protocol’s privacy features, there is no cryptographic way to prove today whether or not the bug itself was exploited before it was patched.

What Happened to ZEC on June 5th, 2026?

As seen in the chart below, ZEC experienced a massive crash on June 5th, 2026, losing more than 45% of its value and plummeting from above $600 to around $300 in a matter of hours. The sudden move followed a disclosure from the protocol’s founder, bringing to light a massive vulnerability that may have allowed attackers to mint counterfeit tokens.

Let’s dive a bit deeper.

According to Zooko’s post on Twitter, security researcher Taylor Hornby discovered the vulnerability on May 29th, 2026, while reviewing the protocol’s Orchard circuit. To those unaware, Orchard is one of Zcash’s shielded pools – the part of the protocol that makes private transactions possible.

Hornby had been hired by Shielded Labs back in April 2026 to conduct ongoing security research on the protocol. His job was to look for hidden flaws before malicious hackers could find it.

The discovery came relatively short after Antrophic released its Opus 4.8 AI model on May 28th. In fact, Hornby used this same model as part of a targeted audit of the Orchard circuit. He combined AI-assisted review with traditional security research, and one day later he found the bug and disclosed it to the Zcash Open Development Lab, or ZODL for short.

ZODL then coordinated an emergency response throughout the entire Zcash ecosystem, completing the fix by June 2nd, and thereby closing the window of risk. But that’s not the end of the story, because the bug could have caused damage before it was fixed. Allow me to explain.

Why This Bug Was So Serious

Put in simple terms, the vulnerability could have allowed for someone to create fake ZEC inside Orchard.

Cryptocurrencies usually rely on very strict rules to prevent counterfeiting. A blockchain must absolutely know, at all times, that coins being spent really exist and that no one is secretly creating more than allowed. Zcash has a maximum supply of 21 million ZEC, similar to Bitcoin’s fixed-supply model. If someone is able to create unlimited fake ZEC, that would undermine one of the most basic and fundamental promises of the system itself.

The vulnerability was caused by what the authors described as an “under-constrained” element in the Orchard circuit. Now, a circuit is a mathematical system used to verify that a private Zcash transaction follows the rules without revealing sensitive details. These are the details about the sender, the receiver, and the amount.

“Under-constrained” here means that the circuit did not fully check something it was supposed to be checking. In this case, the flaw enabled the insertion of false inputs into a core cryptographic operation, elliptic curve multiplication, while still making the proof appear valid.

The researcher reportedly built a complete exploit and tested it in a local environment. During that test, the exploit generated virtually unlimited undetectable counterfeit ZEC. The authors admitted that if the same tool had been used on mainnet before the fix, it would have generated counterfeit ZEC directly in the real Zcash wallet.

The Tradeoff for Privacy

The crucial part of this disclosure is not only that the bug existed, but that Zcash’s privacy design makes it impossible to prove whether it was ever exploited before the fix. And it has been here for a while. To be precise – since Orchard was activated in May 2022. So that’s over 4 full years it could have been exploited.

Zcash’s protocol is designed so that shielded transactions do not reveal public details about who sent the funds, who received them, or how much was transferred. That privacy is the whole point of the system. At the same time, though, it makes forensic analysis that much harder.

On a traditional public and transparent blockchain, investigators are able to trace abnormal coin creation or suspicious transaction patterns. In Orchard, the relevant information, which could essentially point to any potential damages, is hidden by design. As a result, the authors concluded that there is no definitive cryptographic way of determining whether counterfeited coins were created before the vulnerability was patched.

It’s important to note that this doesn’t mean that counterfeiting happened – it just means there’s no way to prove it doesn’t.

Authors Think Exploitation Was Unlikely: Here’s Why

Despite the serious nature of the vulnerability, the authors argue that prior exploitation was probably unlikely.

The first reason they outline is that the vulnerability had gone unnoticed for years, despite Zcash’s protocol being reviewed by experienced security engineers and cryptographers. Orchard was activated back in May 2022, as we mentioned above, which means that the bug was there for four years without it being discoverd (or at least not that we know of such discovery).

The second reason is that Hornby was onboarded to specifically search for deep protocol vulnerabilities, and this discovery was not accidental. It was the result of focused security effort using advanced tools and expert judgment.

They also argued that the vulnerability was patched within just a few days after discovery. That said, the authors were very careful in asking the users not to simply trust their judgment, proposing a more formal way of restoring trust.

What’s Next?

First things first, Shielded Labs is working with other Zcash devs on a possible network upgrade that would allow users to reliably verify the integrity of the ZEC supply.

This idea involves creating a new shielded pool and using “turnstile accounting” for coins leaving Orchard. Put simply, this would create a migration path that’s more controlled. Coins could move from the old pool to the new one under rules that are designed to make sure that more ZEC cannot come out than it legitimately went in.

Naturally, this kind of network upgrade wouldn’t take place automatically – it would need community support through the normal government process.

In regards to ZEC’s price action, which is probably one of the things that many users are mostly concerned with, CryptoPotato reached out to leading analytics firm Nansen for an opinion. Commenting on the matter was Nicolai Sondergaard, Research Analyst, who said:

“What markets are reacting to is the part that cannot be fully resolved by the patch. Due to the privacy design of Orchard, there is no cryptographic way to audit whether someone exploited this before the fix. The Zcash team has said exploitation is unlikely, for reasonable reasons, but they have been explicit that they cannot prove it. That is a genuine supply integrity problem. A network upgrade is being proposed that would migrate coins to a new shielded pool with turnstile accounting, allowing independent verification. Until that is live and audited, the honest answer is that current ZEC supply cannot be certified clean.

The price reaction reflects that uncertainty more than the bug itself. A patched vulnerability in a minor privacy coin would ordinarily be a footnote. The -30% move is the market assigning non-trivial probability to the scenario where some counterfeiting did occur and is permanently undetectable without the proposed upgrade.”

Opus 4.8 and Its Role in Discovering this Zcash Vulnerability

One of the most impressive parts of this story is the role of AI-assisted security research.

Taylor Hornby used Anthropic’s Opus 4.8 model as part of the review that led to the discovery.

This doesn’t mean that AI “found the bug on its own.” The disclosure makes it clear that the process involved a very experienced professional, a targeted review, custom tooling, and expert analysis. However, it also shows that AI systems may increasingly become part of high-stakes security work, especially in complex cryptographic systems, where even the smallest mistakes can have disproportionately large consequences.

Shielded Labs said it’s now accelerating this kind of proactive research.

Ripple’s cross-border token is down 14% for the week, but the company continues to score major wins in global expansion and important partnerships.

Bitcoin (BTC) has also plunged substantially, with numerous popular analysts expecting further declines, while Cardano (ADA) collapsed to its lowest level since 2020.

XRP Price Crash

Several days ago, Ripple teamed up with the Turkish crypto platforms BiLira, Bitexen, and Bitlo to boost adoption and usage of RLUSD. Later on, Mastercard expanded its infrastructure to enable merchants and partners to settle transactions in multiple cryptocurrencies, including the USD-pegged stablecoin.

In addition, Ripple strengthened its presence in the United States by opening an expanded office in Washington, D.C., while the spot XRP ETFs remained predominantly positive.

Despite the favorable news, XRP tumbled by 14% over the past week and currently trades at around $1.13 (per CoinGecko). Its poor condition mirrors the collapse of the broader crypto market, where Bitcoin (BTC) slipped to around $61,000 and altcoins like Zcash (ZEC) and Bitcoin Cash (BCH) nosedived by nearly 30%.

Another worrying factor is the recent whale activity. As CryptoPotato reported, this cohort of investors has sold or redistributed 50 million coins in the span of seven days, further spreading panic that could prompt smaller players to cash out as well.

BTC’s Heavy Bleeding

The primary cryptocurrency has lost over $20,000 in the past month alone and recently dropped to approximately $61,000, its lowest mark since February. As of press time, it trades at around $62,800, representing a 15% decline on a weekly scale.

Unsurprisingly, the downward move has resulted in a wave of bearish predictions. Ali Martinez recently opined that the plunge below $72,000 has put BTC in “a vulnerable position,” with the MVRV Pricing Bands suggesting the next major support lies between $50,000 and $54,000.

For his part, Ted labeled $49,000 “a good bottom zone,” comparing the scenario to the August 2024 low. Of course, the well-known crypto critic Peter Schiff was also vocal, envisioning a $20,000 catastrophe if BTC breaks $50,000.

“It should be a quick fall below $20K, which should be a big enough drop to shake the conviction of long-term HODLers, causing many to finally throw in the towel,” he added.

ADA’s Meltdown

Cardano’s native cryptocurrency is among the most heavily affected coins from the market crash. It fell to $0.15 (the lowest point since the end of 2020) before slightly rebounding to around $0.165.

One of the main factors in ADA’s collapse was Charles Hoskinson’s recent announcement. Cardano’s founder said he’s “taking a break,” while also warning about an upcoming “wave of failures in the ecosystem.”

The only positive recent development related to ADA is Cardano’s partnership with the Brazilian Olympic Committee (COB). However, it wasn’t enough to stop the asset’s free fall.

The next massive gains in artificial intelligence may come from thousands of miles away.

Tim Urbanowicz, chief investment strategist at Innovator from Goldman Sachs Asset Management, is urging investors to look beyond their backyards to the emerging markets.

“[It’s] where a lot of the big money can be made on the AI trade,” he told CNBC’s “ETF Edge” this week – calling it “the next big wave.”

Urbanowicz is particularly bullish on Taiwan and South Korea when it comes to the AI build-out. He notes they are a big part of the broad iShares MSCI Emerging Markets ETF, which is up 26% as of Thursday’s close.

“These are major players in the AI trade and the AI space where valuations really haven’t gone up as much as they have in the U.S.” he said. “There’s still a lot of runway in our view to provide outsized gains with this AI trade.”

The iShares MSCI Taiwan ETF is up almost 67% so far this year while the iShares MSCI South Korea ETF market has risen 109%, as of Thursday’s U.S. close. Both Taiwan- and South Korea-focused ETFs hold several AI memory-related chip names.

In a special note to CNBC, Urbanowicz highlighted the actively managed Goldman Sachs ActiveBeta Emerging Markets Equity ETF as a way for investors to gain exposure to potential AI-driven gains in emerging markets.

Getting exposure to AI abroad

Yet, Urbanowicz isn’t abandoning the domestic trade when it comes to AI.

“We think the U.S. is still positioned for success,” he said.

In recent weeks, bitcoin BTC$62,300.09 sentiment has been most bullish when the price was highest and most bearish exactly when it was most stressed, according to Santiment data covering May 21 through June 4.

Peak bullishness hit on May 22, with bitcoin near its high of $78,000 for the period. The most bearish came June 3, with bitcoin near the low. While sentiment is not a timing tool, peak conviction at the highs and peak fear at the lows is the inverse of where the trade usually pays.

Bitcoin was recently trading near $62,400, down about 20% from the late-May peak. The risk picture has cracked alongside it.

The investments into artificial intelligence (AI) companies that pulled global equities to record highs this year has stalled after Broadcom’s chip forecast fell short of expectations. South Korea’s KOSPI index fell 4.7%, and the won and Indonesia’s rupiah are at multiyear lows as capital flees emerging Asia.

U.S. spot bitcoin ETFs ended a 13-day, $4.4 billion outflow streak on Thursday with a tiny $3.05 million inflow. Spot ether ETFs ended their parallel 17-session streak with $19.30 million on the same day. Both numbers are too small relative to the streaks they ended to call it a regime change.
