## What Is Uniswap (V2)?

Uniswap is a [decentralized exchange](https://coinmarketcap.com/alexandria/glossary/decentralized-exchange-dex) (DEX) which first introduced the [automated market maker](https://coinmarketcap.com/alexandria/glossary/automated-market-maker-amm) (AMM) model. Unlike with an [order book](https://coinmarketcap.com/alexandria/glossary/order-book), traders are provided with constant liquidity thanks to the “constant product” formula. The V2 version was first based on [Ethereum](https://coinmarketcap.com/currencies/ethereum/), before branching out to other blockchains that support [ERC-20](https://coinmarketcap.com/alexandria/glossary/erc-20) tokens.

While the V1 version of Uniswap only supported [swapping](https://coinmarketcap.com/alexandria/glossary/token-swap) ETH-ERC-20 token pairs, the V2 version did away with this bridging problem and introduced flash swaps.

It also introduced protocol fees, which contributed to the platform's ongoing development. Furthermore, the V2 version began using [wrapped Ether](https://coinmarketcap.com/alexandria/article/what-is-wrapped-ethereum-weth) over native Ether for its core contracts. 

The exchange’s popularity gave birth to a V3 version with concentrated liquidity and more flexible fees, which improved the user experience for traders and liquidity providers alike.
