What is Uniswap v4 (Ethereum)?
#6Uniswap v4 is the latest iteration of the world's most widely used decentralized exchange protocol, officially launched on January 31, 2025 across 12 blockchain networks simultaneously. Founded by Hayden Adams and developed by Uniswap Labs, the v4 upgrade represents a fundamental architectural redesign aimed at maximizing gas efficiency and developer customizability. The protocol's most significant innovation is a "singleton" architecture where all liquidity pools reside within a single smart contract — reducing the gas cost of creating new pools by an estimated 99% compared to v3. Complementing this is a "hooks" system that allows developers to attach custom smart contracts to any pool, enabling features like dynamic fee structures, on-chain limit orders, and Time-Weighted Average Market Makers (TWAMM) without modifying the core protocol. Additional efficiency improvements include native ETH support (eliminating the need to wrap ETH into WETH) and "flash accounting," which settles only the net balance of assets at the end of a transaction, dramatically reducing costs for multi-hop swaps. Uniswap v4 is deployed on Ethereum, Arbitrum, Avalanche, Base, Blast, BNB Chain, Ink, Optimism, Polygon, and World Chain. Within 177 days of its 2025 launch, the protocol reached $1 billion in Total Value Locked (TVL) and has since processed over $110 billion in cumulative trading volume. As a fully permissionless and non-custodial protocol, it requires no KYC and is governed by UNI token holders.

How does Uniswap v4 (Ethereum) work?
Uniswap v4 (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.
