At #DuneCon2024, Grace Danco and Xin Wan from Uniswap Labs showcased Uniswap's transformation, emphasizing how the forthcoming V4 builds on its predecessors with enhanced flexibility and innovation.

What’s New in V4?

V4 introduces a singleton design, consolidating all pools into a single contract managed by unique "pool keys." This shift simplifies data handling and reduces gas costs by up to 99%. The new hooks system enables developers to customize liquidity pools, supporting dynamic fees, MEV-resistance, and even retroactive V2-like functionality. Native ETH support eliminates wrapping during swaps, further improving efficiency.

Why It Matters

V4 retains V3’s concentrated liquidity model while offering unprecedented customization for developers. With its unopinionated structure, V4 empowers users to shape its applications, potentially revolutionizing DeFi once again. The address mining competition currently underway will determine the next steps for its launch.

Uniswap continues to lead in innovation, and V4’s release promises to redefine the boundaries of decentralized finance.
