ETH Hits 13-Month Low Amid Zcash Bug and Market Turmoil
By John Nada·Jun 6, 2026·6 min read
Ether sank to a 13-month low at $1,540 amid Zcash bug fears and a bearish market. Traders brace as derivatives metrics and TVL contractions heighten risk.
Ether's plunge to a 13-month low of $1,540 marks a chapter in cryptocurrency's volatile story. As Cointelegraph reported, the decline accompanied bearish trends across a shaken market landscape, exacerbated by a critical bug discovered in the Zcash blockchain. The fear of contagion looms large, especially as Ethereum's Total Value Locked (TVL) contracts, causing traders to brace for a deeper correction.
Derivatives metrics paint an unsettling picture. The Ether futures annualized funding rate has flipped negative, signaling a surge in short positions. Confidence among bulls has eroded, with $1.28 billion in leveraged long positions liquidated in just five days. This marks a significant downturn, as even with ETH trading 67% below its all-time high from August 2025, the market sentiment is increasingly bearish.
The negative shift in the Ether futures annualized funding rate is a critical metric to consider. It indicates not only the increased demand for short positions but also a broader lack of confidence in Ether's short-term price prospects. This sentiment is further reflected in the ETH options market. According to Laevitas, the ETH options put-to-call premium at Deribit spiked to 3.7 times, clearly reflecting the market's demand for downside protection. With fear creeping up, bears have found a foothold.
Ethereum's total value locked nosediving to levels unseen since February 2024 hasn’t helped sentiment. Major DApps like Spark and Ether.fi suffered severe contractions in TVL, down 50% and 49% respectively. This downturn can partially be attributed to a vulnerability in Zcash's largest zero-knowledge pool, driving a flight from smart contracts. The implications of the Zcash bug are profound. Discovered using Anthropic's Opus 4.8 AI model, the bug allowed unlimited ZEC minting, sending shockwaves through the blockchain community.
The fear of similar vulnerabilities elsewhere is palpable, given the heightened pace of security breaches. April's hacks worth $630 million have traders on edge. KelpDAO's $293 million breach and Drift Protocol's $280 million exploit represent a large chunk of these losses. With such scenarios, the DeFi industry finds itself scrambling for answers. The hacks occurred across multiple networks, including Ethereum, Solana, Base, BNB Chain, Sui, and PulseChain, highlighting a systemic issue within the broader cryptocurrency ecosystem.
Cointelegraph noted only 30% of ETH supply remains profitable since last moved. This scenario has occurred rarely, with previous instances sparking notable rallies. Traders may wonder if this is a buy signal or a precursor to further turmoil. Historically, such low profitability among ETH holders has occurred only a few times. The most recent instance was during the mid-March 2020 COVID crash, which was followed by a significant price rebound. Prior to that, a similar setup in mid-December 2019 preceded a 118% rally within 60 days.
Bitmine's massive $10.5 billion unrealized loss adds another layer to Ethereum's woes. Holding 4.5% of the total ETH supply, the firm finds itself under immense pressure. The market watches closely, anticipating what could come next. The scale of Bitmine's losses underscores the broader challenges facing institutional investors in the current climate. As one of the largest holders of Ethereum, Bitmine's financial health is closely tied to the performance of the cryptocurrency market.
The Ethereum network's DApps have also been significantly affected by the contraction in TVL. Key applications like EigenCloud and KernelDAO saw TVL reductions of 41% and 39%, respectively. This contraction not only impacts the revenue-generating potential of these applications but also reduces the overall demand for ETH used in smart contracts. The interconnectedness of these applications within the Ethereum ecosystem means that declines in TVL can have far-reaching consequences for the network's health and stability.
The discovery of the Zcash bug using Anthropic's Opus 4.8 AI model marks a significant advancement in AI-driven security failure detection. However, it also highlights the potential vulnerabilities that may exist within other blockchain networks. Given that the Zcash bug had existed since 2022 without detection, there is a growing concern among traders and developers about the security of other smart contracts and blockchain protocols.
The recent spate of hacks, totaling $630 million in April alone, has further fueled these fears. The KelpDAO and Drift Protocol incidents accounted for 82% of the monthly losses across 25 protocols, triggering panic across the decentralized finance (DeFi) industry. This wave of breaches has prompted calls for improved security measures and greater scrutiny of smart contract vulnerabilities. As the industry grapples with these challenges, investors are left questioning the safety and reliability of existing blockchain infrastructures.
The Ethereum market decline has also been influenced by broader macroeconomic factors. As global financial markets face uncertainty, cryptocurrencies have not been immune to these pressures. The confluence of bearish market sentiment, systemic vulnerabilities, and macroeconomic headwinds has created a challenging environment for Ethereum and other cryptocurrencies.
Despite these challenges, some analysts believe that the current market conditions may present buying opportunities for long-term investors. The historical precedent of price rebounds following periods of low profitability among ETH holders suggests that there may be potential for recovery. However, the path forward remains fraught with uncertainty, as the cryptocurrency market continues to navigate a complex landscape.
In addition to the technical and security challenges, Ethereum's market performance is also being impacted by broader regulatory pressures. As governments and regulatory bodies around the world scrutinize the cryptocurrency industry, new regulations could further influence market dynamics. The potential for increased regulation adds another layer of complexity for investors and developers alike, as they seek to adapt to an evolving regulatory environment.
As the Ethereum community responds to these challenges, the focus on innovation and resilience remains paramount. Developers and stakeholders are working to address security vulnerabilities and enhance the robustness of the Ethereum network. The ongoing efforts to improve scalability and reduce transaction costs are also critical to maintaining Ethereum's competitive edge in the blockchain space.
The future trajectory of Ethereum and the broader cryptocurrency market will depend on a variety of factors, including technological advancements, regulatory developments, and global economic conditions. While the current market downturn presents significant challenges, it also underscores the resilience and adaptability of the cryptocurrency community.
As traders and investors assess the current landscape, the lessons learned from past market cycles may offer valuable insights. The history of cryptocurrency markets is marked by periods of volatility and rapid change, yet innovation and growth have persisted. As Ethereum and other blockchain networks continue to evolve, the potential for transformative impact remains, even amid current market uncertainties.
