# Uniswap

> Swap, earn, and build on the leading decentralized crypto trading protocol

Uniswap is a decentralized exchange protocol. It lets users swap tokens and provide liquidity from their own wallets across multiple blockchains, without a centralized intermediary.

Uniswap is a decentralized exchange protocol that lets users trade tokens directly from self-custody wallets through automated liquidity pools. Its smart contracts run on Ethereum and multiple other blockchains, and anyone can create a pool or supply liquidity to earn a share of trading fees. It is used through the Uniswap web app, the Uniswap Wallet, and applications that integrate its contracts.

Several versions of the protocol run side by side. Uniswap V2 pools pair any two tokens at a constant-product price, Uniswap V3 lets liquidity providers concentrate capital within chosen price ranges, and Uniswap V4 adds hooks, plugins that let developers attach custom logic to pools, swaps, and fees. UNI holders govern the protocol through on-chain votes on upgrades, fee settings, and treasury spending.

Alongside the protocol, Uniswap runs Unichain, an Ethereum Layer 2 network built for trading and liquidity, and the Uniswap Wallet, a self-custody wallet for mobile and browser. Uniswap is used by traders, liquidity providers, developers building on its contracts, and other DeFi protocols that route trades through its pools.

## Products

- [Uniswap V4](https://thegrid.id/profiles/Uniswap): Uniswap V4 is the current version of the Uniswap decentralized exchange protocol, with every pool held in a single contract. Developers can attach hooks, contracts that add custom logic such as dynamic fees, limit orders, or automated liquidity management, to individual pools. It keeps concentrated liquidity from earlier versions, lowers gas costs for swaps and pool creation, and supports pairs in native ETH. (Decentralised Exchange, Live)
- [Uniswap V3](https://thegrid.id/profiles/Uniswap): Uniswap V3 is a version of the Uniswap decentralized exchange protocol built on concentrated liquidity. Liquidity providers choose the price range in which their capital is active, and each pair can have pools at several fee tiers. Each position is held as a non-fungible token carrying its own range and fee settings, and pools also serve as on-chain price oracles. (Decentralised Exchange, Live, Main Product)
- [Unichain](https://thegrid.id/profiles/Uniswap): Unichain is an Ethereum Layer 2 network built for decentralized trading and liquidity. It is an optimistic rollup with permissionless fault proofs that produces one-second blocks, with faster preconfirmations to cut latency and reduce value lost to MEV. As part of the Superchain, it connects natively with other networks in that group, and transactions pay gas in ETH. (L2, Live)
- [Uniswap Wallet](https://thegrid.id/profiles/Uniswap): Uniswap Wallet is a self-custody wallet available as a mobile app and a browser extension. Users can swap tokens, buy and sell crypto with a debit card or bank account, send and receive assets, and bridge between networks from one app. It also lets users deposit supported assets to earn yield and connect to decentralized applications across multiple blockchains. (Wallet, Live)
- [Uniswap protocol](https://thegrid.id/profiles/Uniswap): Uniswap Protocol is automated market maker through smart contracts, enabling peer-to-peer cryptocurrency trading without intermediaries using liquidity pools and constant product formula. (Decentralised Exchange, Live)
- [Uniswap V2](https://thegrid.id/profiles/Uniswap): Uniswap V2 is a version of the Uniswap decentralized exchange protocol that pairs any two ERC-20 tokens in a liquidity pool priced by a constant-product formula. Liquidity providers deposit both tokens and earn a share of the fee on every swap in that pool. Each pair also records cumulative prices that other contracts can read as an on-chain price oracle. (Decentralised Exchange, Live)

## Assets

- [Uniswap (UNI)](https://thegrid.id/profiles/Uniswap): UNI is the governance token of Uniswap. It is used to vote on protocol upgrades, treasury allocation, and fee parameters through on-chain governance mechanisms. Holders can delegate their tokens to participate in voting, with voting weight determined by the number of delegated UNI at the time a proposal becomes active. (Governance)
