## Description

Angela Ocando from the Uniswap Foundation discusses how "hooks" are revolutionizing DeFi by enabling customizable, programmable liquidity pools on Uniswap v4. She explains the evolution from traditional finance’s closed, permissioned systems to DeFi’s open, permissionless infrastructure, highlighting Uniswap’s role in this transformation. Hooks allow developers to add custom logic before and after swaps, enabling innovations like time-weighted average market makers, dynamic fees, and on-chain limit orders.

Angela emphasizes the composability and flexibility hooks bring, likening them to "money legos" for DeFi. She introduces Uniswap Foundation’s resources for builders, including grants, education, hackathons, and a hook incubator, encouraging participation in the evolving DeFi ecosystem. The talk underscores programmable liquidity as foundational for the future of open finance and invites developers, founders, and business professionals to contribute to DeFi’s growth.
