Zcash nosedives after counterfeit vulnerability revealed

The privacy-focused cryptocurrency has dropped more than 40% in the last 24 hours, shedding $3.8 billion in market capitalization.

Zcash, the native cryptocurrency for the privacy-focused blockchain bearing the same name, has cratered after Shielded Labs, an independent organization supporting the network, disclosed a counterfeit vulnerability that has since been patched after going undetected by world’s best cryptographers since 2022.

The token has plummeted more than 40% in the past 24 hours, shedding $3.8 billion in market capitalization.

The vulnerability was in Orchard, one of the network’s shielded pools that preserves privacy by using zero-knowledge cryptography to conceal transaction details and token ownership.

“The vulnerability could have been exploited to undetectably create an unlimited amount of counterfeit ZEC within Orchard,” according to a Thursday report from Shielded Labs. “Because of the privacy properties of Orchard, there is no way to cryptographically prove whether the vulnerability was exploited before it was remediated.”

Even though the vulnerability was patched in an emergency fix on Monday, the disclosure on Thursday was enough to spook a number of holders into completely reducing their exposure. Arthur Hayes, cofounder of crypto exchange BitMex and CIO of Maelstrom, dumped his entire bag of Zcash, saying on X, “The privacy from AI, govt, big tech narrative demands perfection not improbability.”

Meanwhile, Taylor Hornby, the security researcher who identified the vulnerability, had used Anthropics Opus 4.8 model to make the discovery.

The announcement from Shielded Labs comes as the decentralized finance ecosystem is still recovering from several substantial attacks in April, namely KelpDAO’s $290 million exploit and Drift’s $270 million hack. That month, Anthropic also said its Claude Mythos Preview AI model had found thousands of high-severity vulnerabilities “in every major operating system,” showing how artificial intelligence can outperform nearly all human experts at exploiting software vulnerabilities.

“A network upgrade can be deployed to protect users and prove the integrity of the Zcash supply,” the report stated. Shielded Labs, alongside different Zcash developers, are currently evaluating a network upgrade that would enable the public to verify the token’s supply and confirm counterfeit coins in the Orchard pool do not exist.

Zcash is trading just above the $300 level, down from $600 earlier this week. In the last 24 hours, the cryptocurrency saw $120 million in liquidations, with over 61% coming from long positions, data from CoinGlass shows.

Hyperliquid reclaims all-time high

HYPE, the native token powering perpetuals exchange Hyperliquid and its underlying blockchain, rebounded to reclaim its all-time high previously set at the start of the month.

Treasury firms Hyperliquid Strategies and Hyperion DeFi have also rallied as the token increased double digits in the last 24 hours to trade as high as $76.70, rising past its record price set nearly two weeks ago, according to CoinGecko. In the interim between all-time highs, HYPE pulled back to around $53.

The token has several tailwinds, the first coming from ETF flows. Since their inception in May, HYPE ETFs have yet to record negative weekly outflows, posting a cumulative total net inflow of $171.8 million, per SoSoValue.

The second comes from Hyperliquid spending basically everything it earns in fees to buy HYPE, a mechanism embedded into the protocol’s codebase.

The venue’s buyback funding mechanism is set to add a new source of yield. Validators of the network activated “AQAv2,” which means stablecoin deployers will share about 90% of reserve yield revenue on their supply within the protocol.

Around $6.1 billion of Circle’s USDC resides in Hyperliquid, per DefiLlama. Accrual begins on August 26 and the first payment is made on October 3, the network announced in its Discord channel last week.

A substantial amount of capital is riding on different positions of HYPE. In total, a move down to under $53 would result in the liquidation nearly 1.8 million HYPE worth of leveraged long positions on the on-chain perps venue, or $131.7 million, data from CoinGlass shows. For the upside, a climb above $100 results in the liquidation of more than 3 million worth of leveraged HYPE short positions, or $221.5 million.

HYPE’s rebound to all-time high comes after Michael Selig, chair of the Commodity Futures Trading Commission, defended his agency’s decision to approve regulated perpetuals, or futures contracts without expiration dates, CNBC reported on Monday.

Last month, the CFTC approved bitcoin perpetual futures trading in the US through regulated prediction markets firm Kalshi and an affiliate of centralized exchange Coinbase.

“Perps are highly likely to become lightly regulated and thus approved in the US,” said David Pakman, head of venture investments at CoinFund.

“We expect to see perps for many different types of assets, from commodities to equities,” Pakman told Sherwood News.

Crypto market snaps back as sentiment lifts, with altcoins from ethereum to XRP soaring

The market capitalization of the crypto industry has jumped around $83.2 billion in the last 24 hours, with privacy-focused token Zcash and worldcoin, the native cryptocurrency of the network backed by OpenAI CEO Sam Altman, leading market gains, jumping over 22%.

But the last 24 hours have been good across the board:

Investors have been eager to see some positive signs around the Iranian conflict ending, coupled with hopeful outlooks around the CLARITY act, both breathing some life into assets, Kairos Research cofounder Ian Unsworth told Sherwood News.

Simon Shockey, a crypto strategist at crypto wallet infrastructure firm Privy, said the upswing stems from several things converging. He pointed to how alt markets broadly were very oversold following the bug found in Zcash that shook confidence.

Friday, Zcash founder Zooko Wilcox said Anthropic didn’t find any more serious bugs with the Zcash protocol after Shielded Labs requested the AI firm run a security audit of the network with Mythos.

Shockey added that the pool of willing sellers has dwindled. Even if structurally, AI is a much more compelling and asymmetric bet in the eyes of allocators, many of these crypto assets have simply run out of marginal sellers despite some shorter-term narrative-driven pumps. The only people left to sell at this point are the teams themselves and VCs.

Net-net: oversold conditions plus exhausted seller bases plus a macro backdrop thats stabilized equals a snapback, especially in names that have real usage or community conviction behind them,” Shockey told Sherwood.
