Uniswap V4 Singleton Design

Architecture

Uniswap V4’s singleton design proposes a single smart contract to manage all liquidity pools, contrasting with previous versions where each pool was a separate contract. This architecture aims to significantly reduce gas costs for multi-pool operations and simplify smart contract interactions. By consolidating logic into one contract, it enables more efficient routing of trades and atomic execution across different asset pairs. This innovative design optimizes the underlying infrastructure for decentralized exchanges. It represents a notable evolution in AMM design.
