## 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. These allowed users to swap between different ERC-20 tokens without incurring too much [slippage](https://coinmarketcap.com/alexandria/glossary/slippage). 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.
