The cryptocurrency market is witnessing significant turbulence as Ethereum (ETH) plummeted to a 13-month low of $1,540 on Friday. This decline is part of a broader bearish trend, exacerbated by a critical bug discovered in the Zcash blockchain and weakening derivatives metrics. Traders are now bracing for a deeper price correction as confidence in the market erodes.
The recent downturn has been fueled by a combination of factors, including a surge in liquidations, a shift in derivatives metrics, and heightened security concerns across the blockchain ecosystem. The discovery of a critical vulnerability in Zcash, which allows for unlimited minting of ZEC, has particularly rattled investors, raising fears of potential contagion across other blockchains and smart contracts.
The Shift in Ethereum Derivatives Metrics
The Ether futures annualized funding rate turned negative on Friday, indicating a growing demand for short positions. This shift comes even as ETH trades 67% below its all-time high from August 2026. The market has seen a significant liquidation of leveraged longs, with over $1.28 billion in positions wiped out over five days. This has shattered bullish confidence and paved the way for further declines.
In the options market, the Deribit ETH options put-to-call premium spiked to 3.7 times on Friday, reflecting a surge in demand for downside price protection. This indicator has consistently shown excess demand for put options since Monday, signaling low conviction among holders and a bearish sentiment dominating the market.
The Impact of the Zcash Bug on Ethereum
The severe decline in Ethereum’s Total Value Locked (TVL) to its lowest level since February 2026 has further dampened trader sentiment. Smaller deposits in decentralized applications (DApps) reduce ecosystem revenue, ultimately decreasing the demand for ETH in smart contracts. Top Ethereum DApps, including SparkEther.fiEigenCloudand KernelDAOhave experienced significant TVL contractions, with losses ranging from 39% to 50%.
The critical vulnerability in Zcash, discovered on May 29 using the Opus 4.8 AI model from Anthropichas intensified concerns about the security of other blockchains. The bug, which had existed since 2026 without detection, highlights the potential risks lurking in the blockchain ecosystem. This has put investors on high alert, especially in light of recent cryptocurrency hacks totaling $630 million in April.
The Broader Implications for the Cryptocurrency Market
The recent hacks, including the $293 million exploit of KelpDAO and the $280 million breach of Drift Protocolhave accounted for 82% of the monthly losses across 25 protocols. These incidents have triggered panic across the decentralized finance (DeFi) industry, with hacks occurring across multiple networks, including Ethereum, Solana, Base, BNB Chain, Sui, and PulseChain.
Currently, only 30% of the ETH supply is profitable relative to when those coins were last moved. This setup has occurred only a few times in history, with the most recent instance being the mid-March 2026 COVID crash. Prior to that, this strong buy signal also emerged in mid-December 2019, preceding a 118% rally within 60 days.
With over $500 million in leveraged ETH long positions liquidated in 48 hours, there are no signs of a relief bounce. The largest Ethereum treasury firm, Bitmine (BMNR US)is sitting on an unprecedented $10.5 billion unrealized loss, as the company holds 4.5% of the entire ETH supply. This further complicates the outlook for Ethereum, with prices potentially sliding further below $1,550 as investor confidence deteriorates.
