ETH Dips to 13-Month Low as Zcash Bug News and BTC Falls Under $60K

Ether (ETH) slid to a 13-month low near $1,540 on Friday as risk-off sentiment seeped through crypto markets. The move came amid a cascade of derivative-driven liquidity drains and fresh security worries that have kept bulls on the back foot even as ETH trades well below its late-2025 highs. In parallel, a critical vulnerability in Zcash’s shielded pool—exposed by AI-driven tooling—fed fears of broader contagion across blockchains and DeFi protocols.

On the macro side, derivatives data painted a decidedly bearish picture. Futures markets showed negative funding rates, signaling higher demand for short exposure, while a wave of leveraged longs was liquidated, eroding any quick relief rally. The market backdrop was underscored by a sharp pullback in ETH’s real-use case metrics, with Ethereum’s Total Value Locked (TVL) signaling a pullback in DeFi activity and wallet flows remaining strained.

Key takeaways

• Ether derivatives tilt bearishly as cascading liquidations erase attempts at relief, with leveraged longs cut by over $1.28 billion across a five‑day window.
• Negative annualized funding rates for ETH perpetual futures indicate continued appetite for short bets, reinforcing a risk-off posture among traders.
• Demand for downside protection spikes in options, with Deribit ETH put-to-call premium reaching multi‑week highs, signaling growing hedging interest amid uncertain momentum.
• Ethereum’s on-chain activity frays as TVL sinks to the weakest level since February 2024, with notable DApps posting multi‑tens of percent contractions in user and capital inflows.
• A AI‑driven discovery of a Zcash vulnerability stokes fears of systemic risk, as investors question whether other networks could harbor similar blind spots.

Derivatives signal a risk-off regime for ETH

Market data show a clear tilt toward selling pressure in ether derivatives. The perpetual futures market turned negative on Friday, reflecting a thinning of upside conviction and a shift toward hedges or outright shorts. This dynamic is particularly concerning for bulls, given that ETH had already traded about 67% below its all‑time high from August 2025.

In the backdrop, roughly $1.28 billion in highly leveraged long positions were liquidated over five days, dimming prospects for a swift bounce. While price action remains volatile, the combination of losses and negative funding metrics underscores a fragile balance for those seeking risk-on momentum in ETH.

The derivatives picture is complemented by a rising demand for downside hedges in the options market. Data show the ETH put-to-call premium on Deribit climbing to roughly 3.7x on Friday, with the metric lingering at elevated levels since early in the week. This pattern points to a crowded hedging psyche among market participants and suggests that casual bidders may remain reluctant to chase rallies in the near term.

ETHTVL and DeFi activity: a pullback across the ecosystem

The retreat in on-chain activity is visible in Ethereum’s ecosystem metrics. DefiLlama data indicate Ethereum’s network TVL has slid to its lowest level since February 2024, a development that cynically reduces the available on-chain liquidity for users and dampens the revenue prospects for DApps built on the network.

Top ETH-based decentralized applications have also borne the brunt of this shift. Spark, Ether.fi, EigenCloud, and KernelDAO each reported double-digit declines in TVL, reflecting a broader correction in DeFi liquidity as funds migrate away from riskier protocols amid higher macro uncertainty.

The timing of this TVL erosion intersects with a broader narrative about security and risk in DeFi: a bug in Zcash’s shielded pool was discovered to enable unlimited minting, a finding attributed to AI-powered review tooling. While the vulnerability relates to Zcash specifically, it has intensified concerns about whether other chains harbor hidden flaws that could catalyze outflows and force risk repricing across ecosystems. The exposure was reported on a May 29 discovery using Anthropic’s Opus 4.8 AI model, amplifying market nerves about cross-chain contagion.

Beyond the immediate concern about security, April’s hack-and-exploit wave continued to color risk assessments. Across 25 protocols, hacks by KelpDAO and Drift Protocol accounted for a large share of losses—together around $573 million—illustrating how breaches have stressed a broad set of networks and liquidity pools, and implying that risk management remains a central topic for users and builders alike.

Supply dynamics and what they imply for ETH risk and recovery

On-chain supply metrics add another layer to the bear case. Glassnode data show that only about 30% of ETH supply remains profitable relative to the last time those coins moved. This kind of supply dynamic has historically preceded meaningful price action, contrasting with episodes where a larger portion of supply was profitable and markets traded in a more constructive fashion. In the current context, a limited pool of “on‑the‑move” ETH suggests fewer buyers stepping in to relieve selling pressure unless a catalyst appears.

Further complicating the outlook is the scale of unrealized losses in top ETH treasury holders. Bitmine (BMNR US), the largest ETH treasury holder, reportedly sits on an unrealized loss of about $10.5 billion, representing roughly 4.5% of the entire ETH supply. If the market continues to tighten and lenders and lenders’ risk appetites stay constrained, such concentrated exposure can amplify downside volatility during forced liquidations or correlated de-risking waves.

Taken together, these data points suggest a fragile recovery path for ETH at present. Prices could press lower toward key levels, with the psychological threshold near $1,550 providing a potential point of relief if buyers emerge. However, the confluence of weak on-chain activity, persistent derivatives headwinds, and the specter of cross-chain vulnerabilities keeps the risk skewed to the downside in the near term.

For readers tracking risk and opportunity, the next few weeks will be telling. Watch for fresh data on DeFi liquidity, any new security alerts across major networks, and whether cross-chain risk dynamics begin to stabilize as market participants reassess hedging needs and capital allocation.
