This led to roughly $200 million in bad debt discussions and liquidity stress. This article provides an objective review of the event sequence and structural takeaways from the perspectives of mechanism, marketplace response, and governance framework.

Since 2026, DeFi security incidents have demonstrated concurrent patterns involving protocol vulnerabilities, front-end hijacking, and approval phishing. Drawing on this year's notable security cases, this article provides a systematic overview of Wallet layering, approval management, signature verification, and emergency response procedures, enabling regular users to build a practical and reusable on-chain security risk control system.

To strengthen blockchain application security, the Ethereum Foundation has introduced a new audit grant program. Through financial support and partnerships with professional institutions, the program reduces the cost threshold for Developers to perform security audits. In this article, you'll learn how the program works, the criteria for participation, and its broader implications for the crypto industry.

CoW Swap has suspended its services following a DNS hijacking incident targeting its frontend website. While the core protocol remains unaffected, this event underscores the persistent security risks facing DeFi frontends. In this article, we will examine the attack mechanism, the scope of its impact, and recommended preventive strategies.

Recently, an address contamination attack has targeted Squads multi-signature Wallet users. While no Assets have been lost, the attack could mislead users through interface manipulation and prompt incorrect actions.

With the ongoing growth of the Solana ecosystem, security concerns are becoming more critical. In response, the Solana Foundation has launched several new security programs, such as the STRIDE security framework and the SIRN incident response network. Additionally, developers are being offered security tools and support to strengthen the ecosystem's overall defense and transparency.

Aave is entering a new phase of node restructuring. With Aave V4 going live, Horizon progressing, and core service providers being replaced one after another, Aave is not simply undergoing a protocol upgrade; it is experiencing a comprehensive system overhaul focused on governance, Risk Control, and institutional capabilities.

Security researchers have identified that hackers are exploiting "search poisoning" to manipulate Bing AI search results, steering users toward downloading a fake OpenClaw application embedded with infostealer malware, leading to the theft of crypto assets and sensitive information. This article examines the attack methodology, technical specifics, and the broader implications for the industry.

The primary difference between Cardano and Ethereum lies in their ledger models and development philosophies. Cardano adopts the Extended UTXO (EUTXO) model derived from Bitcoin and emphasizes formal verification and academic rigor. Ethereum, by contrast, uses an account-based model and, as a pioneer of smart contracts, prioritizes rapid ecosystem iteration and broad compatibility.
