Tue, Dec 2, 2025, 12:00 AM

Tracing Uniswap's evolution from V1's innovative constant product AMM through V2's flash loans and direct ERC-20 trading, V3's concentrated liquidity revolution, to V4's groundbreaking hooks system. Each version introduced powerful innovations - from eliminating complicated pool routes to enabling capital-efficient liquidity provision to allowing unlimited customization—but also opened new attack vectors that developers must be aware of. We examine how architectural decisions created distinct vulnerability classes: V2's price manipulation and sandwich attacks, V3's amplified MEV exploitation and just-in-time liquidity risks, and V4's hook validation and reentrancy challenges. We explore the defensive strategies needed to safely navigate each version's unique threat landscape while leveraging their innovations. This technical deep-dive will equip attendees with both the knowledge of Uniswap's capabilities and the security mindset essential for building robust DeFi applications.
