Uniswap v3 Core introduces significant advancements over its predecessors as a noncustodial automated market maker on the Ethereum Virtual Machine. The document highlights increased capital efficiency through concentrated liquidity, allowing providers to specify price ranges. It also details a more flexible fee structure with multiple tiers per trading pair and enhanced governance control over protocol fees. Furthermore, Uniswap v3 features an improved price oracle that simplifies TWAP calculations and a new liquidity oracle. These upgrades are implemented via a new set of non-upgradeable smart contracts, marking a substantial evolution in decentralized exchange functionality.
