Uniswap is the leading automated market maker. V3 introduced concentrated-liquidity ranges; V4 introduced 'hooks' that let pools embed custom logic (TWAMM, dynamic fees, on-chain limit orders) without forking the core contract.
The AMM pioneer and largest spot DEX by volume.

Largest spot DEX by volume; V4 hooks make pools programmable, and UniswapX delivers intent-based, cross-chain routing. Runs its own L2 (Unichain).
The core on-chain automated market maker (AMM) smart contracts. v2 pioneered the constant-product xy=k pools with token-to-token routing and flash swaps; v3 (2021) introduced concentrated liquidity and multiple fee tiers (0.05% / 0.30% / 1.00%); v4 (2025) added hooks, a singleton PoolManager architecture, and flash accounting.
Optional contracts that run at defined points in a pool's lifecycle (before/after swap, add/remove liquidity), letting developers extend pools with custom logic such as dynamic fees, on-chain limit orders, and TWAMMs without changing the core protocol.
In v4 all pools live inside a single smart contract (singleton), reducing pool-creation gas by an estimated ~99% versus deploying a contract per pool, while flash accounting nets balances across a transaction and only settles net deltas.
An intent-based, permissionless, Dutch-auction trading protocol. Swappers sign an off-chain order and an open network of third-party fillers competes to fill it using on-chain liquidity, paying gas on the swapper's behalf and returning MEV to traders as price improvement.
Uniswap Labs' Ethereum Layer 2, built on the OP Stack, with ~1-second block times and gas costs roughly 95% lower than Ethereum L1, launched as a Stage 1 rollup with a permissionless fault-proof system.
UNI is the ERC-20 governance token launched in September 2020. Holders govern the DAO/treasury, and following the 2025 UNIfication vote, protocol fees are directed to a UNI burn mechanism.

The Block - UNIfication passesHow Uniswap maps onto established TradFi structures, and where it diverges.
Stock exchange / spot trading venue (e.g. NYSE, Nasdaq)
Uniswap
Both are venues where market participants trade one asset for another and where liquidity and price discovery happen continuously.
TradFi analogue
Uniswap has no order book, no designated market makers or brokers, and no central operator; prices are set by an automated pricing curve and anyone can permissionlessly list a pair, provide liquidity, or trade non-custodially from their own wallet.
Market maker / liquidity provision desk
Uniswap
Uniswap LPs perform the economic function of a market maker: they post two-sided liquidity and earn the spread (swap fee).
TradFi analogue
LPing is passive and rule-based rather than actively quoted; returns depend on fees minus impermanent loss, capital is pooled from anyone, and positions are transparent on-chain rather than run by a proprietary trading firm.
Uniswap Labs
Core developer / company The company founded by Hayden Adams that builds the Uniswap Protocol, the web/mobile app, UniswapX and Unichain. Raised an $11M Series A (2020) and a $165M Series B (2022).
Uniswap Foundation
Ecosystem foundation Delaware-based non-profit foundation created by governance in August 2022 (Devin Walsh, executive director; Ken Ng) to steward grants, governance and protocol development, initially funded from the DAO treasury.
Uniswap DAO / Governance
On-chain governance UNI holders govern the treasury and protocol parameters via on-chain proposals and voting, e.g., the 2022 foundation creation and the 2025 UNIfication fee-switch/burn proposal.

Key milestones: launches, upgrades, exploits and governance events.
Uniswap v1 deployed on Ethereum mainnet
ExecutedHayden Adams launched Uniswap v1, a proof-of-concept AMM supporting ETH-to-token pairs, during the week of Devcon IV.
SourceUniswap v2 launched
Executedv2 added direct ERC-20-to-ERC-20 pools, flash swaps and on-chain price oracles, which drove Uniswap's rise as a leading spot DEX.
SourceUniswap v3 launched
Executedv3 introduced concentrated liquidity (up to ~4000x capital efficiency) and three LP fee tiers (0.05% / 0.30% / 1.00%) on Ethereum, followed by an Optimism L2 deployment.
SourceUniswapX protocol introduced
ExecutedUniswap Labs unveiled UniswapX, an intent-based Dutch-auction protocol with third-party fillers and gasless swaps, rolled out as an opt-in beta on Ethereum mainnet.
SourceUniswap v4 mainnet release
ExecutedThe hooks/singleton/flash-accounting architecture went live across ten networks after being released as draft code in June 2023 to be built in public.
SourceUnichain L2 mainnet
ExecutedUniswap's own Ethereum L2 went to public mainnet after an October 2024 announcement and testnet.
SourceUNIfication proposal published
ExecutedUniswap Labs and the Uniswap Foundation proposed activating protocol fees, using them to burn UNI, and burning 100M UNI from the treasury; later approved by governance.
SourceUniswap is an automated market maker: instead of an order book, liquidity providers deposit token pairs into pools and traders swap against those pools. Prices are set algorithmically by the pool's constant-product formula (v2) or concentrated-liquidity curve (v3/v4), and LPs earn the pool's swap fee.
Introduced in v3, concentrated liquidity lets LPs allocate capital to a custom price range rather than across the whole curve, providing up to ~4000x more capital efficiency than v2 for LPs who choose ranges well, but exposing them to more active management and impermanent loss if price leaves the range.
Hooks are contracts attached to a pool that run custom logic at points like before/after a swap or liquidity change. They enable features such as dynamic fees, on-chain limit orders, and TWAMMs. Because hooks are third-party code, the specific hook attached to a pool is itself a smart-contract risk surface.
Uniswap v4 deployed on day one (January 2025) across Ethereum, Polygon, Arbitrum, OP Mainnet, Base, BNB Chain, Blast, World Chain, Avalanche and Zora. Uniswap Labs also runs its own L2, Unichain.
UNI is the governance token used to vote on the DAO treasury and protocol changes. In the 2025 'UNIfication' vote, governance approved activating protocol fees and using them to burn UNI, plus a one-time burn of 100 million UNI from the treasury.
v3 pools offer LP fee tiers of 0.05%, 0.30% and 1.00% depending on the pair. Under UNIfication, v2 LP fees move from 0.30% to 0.25% with a 0.05% protocol fee, and v3 protocol fees are set at a fraction of LP fees (1/4 for smaller pools, 1/6 for larger).
