Uniswap Labs has officially launched Uniswap v4, introducing groundbreaking features like "hooks"—custom smart contracts that allow developers to tailor liquidity pool behavior—and singleton architecture, which drastically reduces gas costs by pooling all smart contracts under one address.
🔧 What’s New in Uniswap v4
Hooks: Custom logic before or after a swap (e.g., on-chain TWAP, dynamic fees).
Singleton Architecture: All pools are deployed under one contract, saving users up to 15–25% on gas fees.
Flash Accounting Model: Improves capital efficiency and precision.
Native ETH Support: No need to wrap ETH to trade.
Why This Matters
Uniswap remains the largest DEX by volume. With v4, it’s leveling up to compete with centralized exchanges by becoming:
More developer-friendly
More cost-efficient for traders
Composable, allowing more experimentation in DeFi
💭 My Take:
Uniswap v4 could supercharge DeFi innovation on Ethereum. Hooks offer flexibility for devs to experiment with ideas that could lead to new yield strategies, automated LP adjustments, and better AMMs. It may also reignite developer interest in Ethereum despite high fees.
