Uniswap v4 features a singleton architecture for enhanced gas efficiency, continuous and dynamic fee spectrum, ERC6909 internal claims tokens, flash accounting, and most notably, programmable hooks. Hooks allow developers to customize pool behavior, enabling programmable liquidity and supporting new asset classes, dynamic fees, liquidity management, and public goods like oracles and advanced order types. The session categorizes hooks into liquidity profitability, liquidity depth, asset class customization, and public goods, providing examples such as dynamic fees, limit orders, KYC compliance, and volatility oracles. Sauce demonstrates live coding with the v4 template, showing how to build and test hooks using Solidity, and emphasizes the importance of testing. Resources like the hook directory, documentation, and Discord are shared for further support. The session concludes with a Q&A on building hooks for various asset classes and optimizing pools for both liquidity providers and swappers. 00:00 Introduction 00:26 Overview & Speaker Introduction 01:46 Uniswap v4 Metrics & Adoption 02:36 Uniswap v4 vs v3: Key Differences 03:43 Singleton Architecture & Gas Efficiency 04:06 Continuous & Dynamic Fees 04:50 ERC6909, Flash Accounting, and Hooks 05:39 Hooks Overview & Programmable Liquidity 06:54 Types of Hooks: Liquidity Profitability 08:09 Types of Hooks: Liquidity Depth 09:20 Types of Hooks: Asset Class Customization 10:39 Types of Hooks: Public Goods 11:47 Resources & Getting Involved 12:36 Live Coding: Building a Hook 13:36 Dynamic Fees & Custom Logic in Hooks 14:43 After Swap Logic & Monetization 15:38 Liquidity Hooks & Penalties 17:23 Testing Hooks with V4 Template 19:05 Deployment Scripts & Chain Configuration 20:28 Custom Pricing Algorithms in Hooks 22:02 Q&A: Asset Class Hooks & Pool Optimization 24:07 Modifying Liquidity & Flash Accounting 24:35 Closing Remarks _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ ๐Ÿ‡บ๐Ÿ‡ธ *ETHGlobal New York* This workshop is specifically for ETHGlobal New York, a 3-day hackathon held August 15-17, bringing together the most skilled web3 developers, designers and product builders from all around the globe for a weekend-long adventure to advance the Ethereum ecosystem!
