## 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. 


## Who Is the Founder of Uniswap (V2)?

Hayden Adams, a former mechanical engineer at Siemens and Stony Brook University graduate, founded the platform in November 2018. The company behind the DEX raised a seed round from Paradigm and $11 million in a Series A round led by ​​Andreessen Horowitz.

## What Is Uniswap?

Uniswap is one of the most popular cryptocurrency [decentralized exchanges](https://coinmarketcap.com/alexandria/glossary/decentralized-exchange-dex) (DEXs), launching in November 2018. It pioneered the [automated market maker](https://coinmarketcap.com/alexandria/glossary/automated-market-maker-amm) (AMM) model, instead of the traditional order book-based used by exchanges. Uniswap runs on the Ethereum blockchain and uses a number of [smart contracts](https://coinmarketcap.com/alexandria/glossary/smart-contract) to securely swap [ERC-20](https://coinmarketcap.com/alexandria/glossary/erc-20) tokens between users.

The decentralized aspect of the protocol means that there is no single centralized authority that manages and runs the exchange — instead, swaps are done in a [peer-to-peer](https://coinmarketcap.com/alexandria/glossary/peer-to-peer-p2p) (P2P) manner. Moreover, Uniswap strives to solve the [liquidity](https://coinmarketcap.com/alexandria/glossary/liquidity) problem inherent in other exchanges. Uniswap V3 is the 3rd edition of the protocol fitted with updates to improve compensation and provide greater control and flexibility for individual LPs. Uniswap V3 supports over 46.5% of the total DEX trading volume and the protocol reached a cumulative lifetime trading volume of $1 trillion in May 2022.

Uniswap V3 launched in May of 2021, almost 2.5 years after the first version was released, and a year after Uniswap V2 was launched.
