$1.2 billion worth of Bitcoin (BTC) options are set to expire, while Ethereum (ETH) put positions have remained at high levels for a consecutive month.

Crypto analytics platform Greeks.live reported that on July 17, 19,000 BTC options expired, with a Put-Call Ratio (PCR) of 0.9, a max pain point of $63,000, and a nominal value of around $1.2 billion. Meanwhile, 123,000 ETH options expired, with a PCR of 1.61, a max pain point of $1,800, and a nominal value of roughly $230 million. In terms of market performance, BTC has continued to fluctuate above $60,000 this week, having traded in the $60,000 to $65,000 range for over a month. Sharp swings in U.S. equities (SpaceX and storage sectors) have not yet had a noticeable impact on the crypto market. Looking at options positions, around 5% of options expired this week, leading to a slight drop in overall open interest, mainly due to low market volatility and reduced trading opportunities. BTC’s Gamma Exposure (GEX) is mainly concentrated around $64,000 and $70,000. ETH’s GEX is primarily in the $1,825 to $2,000 range, with a relatively dispersed distribution. Some traders have started positioning for a rebound via slightly out-of-the-money options. The proportion of large bullish trades has continued to rise recently, dominated by short-term bull spread buying strategies. Notably, ETH’s Put-Call Ratio has stayed above 1 for a consecutive month, hitting 1.61 this week. The high proportion of put options outstanding reflects clear market divergence on ETH’s future outlook, with intensified bull-bear rivalry.

Ethereum Foundation leverages AI to mine vulnerabilities: Successfully identifies security flaws, notes that manual review remains irreplaceable.

The Ethereum Foundation has disclosed that its Protocol Security team is using AI agents to conduct vulnerability hunting of Ethereum client software to boost network security. During testing, the AI successfully identified a vulnerability in the Gossipsub message propagation protocol that allows remote attackers to trigger node crashes, leading to validator nodes going offline. The flaw has since been patched and assigned CVE ID CVE-2026-34219. However, the foundation notes that AI’s biggest challenge is not discovering vulnerabilities, but distinguishing actual flaws from false positives. AI can generate vulnerability descriptions, impact analyses, and exploit code, but may also produce seemingly plausible yet non-existent issues—requiring security researchers to conduct thorough verification. The foundation outlined three common types of false positives: crashes occurring only in test environments, exploit paths that cannot be leveraged in real-world scenarios, and invalid proofs in formal verification. Additionally, the Ethereum Foundation believes AI is currently better at analyzing individual code issues, but has limited ability to identify complex attack chains formed by multiple legitimate operations—an attack vector that has been the primary cause of breaches for multiple crypto protocols this year. Going forward, the foundation plans to have AI assist in generating potential attack paths, which will then be verified via manual and automated testing to further improve the efficiency and accuracy of vulnerability discovery.
