BackgroundDecentralized Finance (DeFi) has rapidly evolved since 2020:V2 Era: Represented by Uniswap V2 and Aave V2, focused on automated trading and decentralized lending.V3 Era: Addressed capital efficiency, solving low utilization and fragmented liquidity.V4 Era: Moving toward modularity and programmability, aiming for more flexible, composable finance.II. Core Features of DeFi V31. Concentrated LiquidityLiquidity providers (LPs) can allocate funds within specific price ranges, greatly improving capital efficiency and reducing idle liquidity.2. Multiple Fee TiersLPs can choose between different fee levels (e.g., 0.05%, 0.3%, 1%), suiting varied risk/reward strategies.3. Active Position ManagementLPs need to actively manage their positions. This favored the rise of professional market-making teams.4. Industry StandardizationThe V3 model became a benchmark for many DEXs (e.g., PancakeSwap V3, Curve V3).III. Core Features of DeFi V41. Hooks MechanismDevelopers can attach custom logic at different stages of a swap. Examples:Dynamic feesOn-chain limit ordersAutomated yield distribution or fee sharing2. Singleton ArchitectureAll liquidity pools exist within a single contract, cutting down on gas consumption.3. Lower Gas CostsCompared to V3’s multi-contract architecture, V4 transactions and LP operations are far more cost-efficient.4. Modularity and ComposabilityV4 is envisioned as the “App Store of DeFi,” enabling developers to build custom features and new financial products (e.g., RWA, derivatives) with ease.IV.

Future Trends1. V3: Capital Efficiency UpgradeBest suited for professional LPs, offering high capital efficiency but requiring active management.2. V4: Modular “Financial Lego”Hooks + singleton design make DeFi programmable, enabling limitless on-chain innovation.3. Cross-Chain and Multi-Chain GrowthV4’s modular architecture aligns well with cross-chain infrastructure, supporting the next wave of Web3 finance.ConclusionV3’s focus: Boosting capital efficiencyV4’s focus: Unlocking modular, programmable DeFi The evolution of DeFi is moving from capital optimization toward financial composability and innovation. ## Publication Information - [blue](https://paragraph.com/@httpsaibo.network/): Publication homepage - [All Posts](https://paragraph.com/@httpsaibo.network/): More posts from this publication - [RSS Feed](https://api.paragraph.com/blogs/rss/@httpsaibo.network): Subscribe to updates
