VFAT Expands Coverage to Include Uniswap v4

OpenCover's CEO Jeremiah S. presented a new approach to onchain vault protection at the Vault Summit during EthCC. **Key Development:** - Introduction of vault-native risk transfer technology - Built-in protection against hacks, depegs, and protocol failures - Integration directly into onchain vaults rather than separate coverage This marks a shift from traditional insurance models to embedded protection mechanisms within vault infrastructure itself.

OpenCover's new Insured Vault primitive has successfully passed a rigorous security audit conducted by Sherlock, with over 700 security researchers unable to identify a single valid vulnerability. **Key Highlights:** - 700+ security researchers from [@sherlockdefi](https://twitter.com/sherlockdefi) attempted to break the Insured Vault primitive - Zero valid security findings reported - The audit validates the security of OpenCover's latest protocol upgrade The successful audit represents a significant milestone for OpenCover, which provides onchain insurance against smart contract hacks, oracle failures, and other DeFi risks. The team, particularly [@matrixtehen](https://twitter.com/matrixtehen), received recognition for their work on the security-focused implementation. This follows a pattern of thorough security testing in the DeFi space, similar to recent audits like Centrifuge's $250k security contest that concluded in January 2026.

A new interactive resource called the Onchain Risk Map has launched to help users understand DeFi threats. Built in collaboration with Nexus Mutual, the tool categorizes onchain risks into six primary areas: - **Custody risk** - threats related to asset storage - **Transaction risk** - issues with blockchain transactions - **Protocol risk** - vulnerabilities in smart contracts - **Digital asset risk** - token-specific concerns - **Staking risk** - validator and staking-related issues - **Systemic risk** - broader ecosystem threats The map provides a structured framework for navigating the complex landscape of DeFi security concerns. Users can explore the interactive tool at [onchainriskmap.com/map](https://onchainriskmap.com/map) to better understand potential vulnerabilities in their DeFi activities.

OpenCover's CEO breaks down the fundamental risks users face when signing blockchain transactions. The company has developed an **interactive Onchain Risk Map** that categorizes threats into six distinct categories, helping users understand what they're exposed to before confirming transactions. The framework distinguishes between two top-level risk types that every onchain user should be aware of: - **Technical risks** - vulnerabilities in smart contracts and protocol code - **Economic risks** - market-related threats and oracle failures The interactive tool provides a comprehensive view of DeFi security concerns, from smart contract exploits to oracle manipulation. Users can explore each category to better understand how to protect their assets when interacting with decentralized applications. This educational resource aims to make onchain risk assessment more accessible, allowing users to make informed decisions about transaction safety.

OpenCover is hosting an exclusive reception at The Carlton Cannes during EthCC to preview their new **covered vault primitive**. **Key Details:** - Event features an inner circle gathering for institutional leaders - New product specifically designed for institutions, platforms, and fintechs - Focuses on vault risk transfer solutions - Includes champagne and canapés at one of Cannes' iconic venues The covered vault primitive represents OpenCover's expansion into institutional-grade DeFi infrastructure, building on their existing portfolio protection services.
