Embarking on a journey across the ever-evolving landscape of decentralized finance (DeFi), Uniswap has established itself as a veritable titan. Resolutely setting the bar for permissionless, non-upgradable, and decentralized trading, each version of Uniswap has delivered innovations that have expanded its functionality and invigorated the DeFi space at large.
In this article, you’ll delve into the groundbreaking features and architectural transformations of Uniswap’s 4th iteration – Uniswap v4.
Overview of Uniswap v4
Uniswap v4 is a non-custodial automated market maker (AMM) implemented for the Ethereum Virtual Machine (EVM). It is the latest version of the Uniswap Protocol, known for its permissionless, non-upgradable, and decentralized nature. Uniswap v4 focuses on customization and architectural changes to enhance gas efficiency and expand the functionality of the protocol.
One of the key features of Uniswap v4 which is the latest version of Uniswap is the introduction of hooks, which are externally deployed contracts that allow developers to implement custom logic at specific points in a pool’s execution. These hooks provide flexibility and enable the creation of concentrated liquidity pools with customized functionality. Users can augment the existing AMM model and introduce new features such as oracles, time-weighted average price orders, volatility oracles, limit orders, and dynamic fees.
Uniswap v4 adopts a singleton implementation, where all pools are managed by a single contract. This change significantly reduces the cost of pool creation and simplifies multi-hop trades. The protocol also introduces flash accounting, which updates internal net balances instead of making token transfers after each operation, leading to more efficient liquidity routing across multiple pools.
Furthermore, Uniswap v4 brings back support for native ETH in trading pairs, allowing users to trade ETH directly without the need for wrapping it into an ERC-20 token. This improvement reduces gas costs for ETH-related transactions and eliminates the additional complexity of handling both WETH and ETH pairs.
