Uniswap Exchange is a decentralised token exchange protocol built on Ethereum. It uses liquidity pools (instead of order books) and the automated market maker mechanism.

Uniswap was the brainchild of Hayden Adams, a mechanical engineer, who learnt how to write smart contracts by himself whilst working on Uniswap. His friend Karl Floersch convinced Hayden to use the automated market maker model after reading about it in a Vitalik Buterin blogpost.

Uniswap has become the biggest trading protocol with $2.745 billion in total value locked (TVL) as of 2 November 2020 according to DeFi Pulse.
