' 'The platform introduced the concept of [concentrated ' 'liquidity](https://coinmarketcap.com/alexandria/glossary/concentrated-liquidity), ' 'which improves the liquidity providing efficiency and makes ' 'it easier for some assets to gain exposure. \n' '\n' 'Liquidity providers (LPs) can also choose where and how they ' 'allocate their funds. Notably, LPs can supposedly earn higher ' 'rewards on their capital by providing liquidity with up to ' '4000x capital efficiency relative to Uniswap v2.\n' '\n' 'Although Uniswap V3 is an update to previous versions, users ' 'can still trade on [Uniswap ' 'V2](https://coinmarketcap.com/exchanges/uniswap-v2/).\n' '\n' '### Who Are the Founders of Uniswap (V3) (Optimism)?\n' '\n' 'The decentralized exchange was launched by Uniswap Labs, ' 'founded by Hayden Adams.\n' '\n' 'Adams was an engineer at Siemens.

There are three fee categories – 0.05%, 0.30%, ' 'and 1%. The fee is based on the volatility of the trading ' 'pair.
