What is Uniswap v3 (Ethereum)?
#16Uniswap v3 on Ethereum is the third major version of the Uniswap protocol, launched on the Ethereum mainnet on May 5, 2021 by Hayden Adams and Uniswap Labs. It introduced the concept of concentrated liquidity — a breakthrough that transformed how decentralized AMMs operate. With concentrated liquidity, Liquidity Providers (LPs) can allocate their capital within specific price ranges rather than across the entire price curve, achieving up to 4,000x greater capital efficiency compared to Uniswap v2. Each LP position is represented as a Non-Fungible Token (ERC-721), enabling unique, customizable liquidity positions. The protocol offers flexible fee tiers (0.01%, 0.05%, 0.3%, and 1%) to accommodate different asset volatilities and risk profiles. Uniswap v3 on Ethereum remains one of the highest-volume DEX deployments in existence, consistently processing billions of dollars in daily trading volume. The protocol has expanded beyond Ethereum to support Arbitrum, Optimism, Polygon, Base, BNB Chain, Avalanche, Celo, Gnosis, and Unichain. All trading is self-custodial with no KYC requirements, governed by the UNI token community.

How does Uniswap v3 (Ethereum) work?
Uniswap v3 (Ethereum) is an automated market maker (AMM) DEX. Instead of a traditional order book, it uses liquidity pools — smart contracts that hold pairs of tokens. Liquidity providers (LPs) deposit equal values of two tokens into a pool and receive LP tokens representing their share. When a trader swaps tokens, they interact directly with the pool; the AMM algorithm (typically a constant product formula x·y=k) adjusts prices automatically based on supply and demand. LPs earn a portion of every trade's fee proportional to their pool share.
