Uniswap is a decentralized cryptocurrency exchange that operates on the Ethereum blockchain. It was launched in 2018 and has quickly become one of the most popular decentralized exchanges in the cryptocurrency market. Uniswap allows users to trade Ethereum-based tokens without the need for a centralized intermediary. This means that users can trade directly with each other, without the need for a middleman to facilitate the transaction. Uniswap uses an automated market maker (AMM) system, which means that the price of tokens is determined by a mathematical algorithm rather than by supply and demand. This makes Uniswap a more efficient and cost-effective way to trade cryptocurrencies.

The native cryptocurrency of the Uniswap platform is UNI. UNI is an ERC-20 token that was launched in September 2020. It was created to incentivize users to participate in the Uniswap ecosystem by providing them with governance rights and a share of the platform's fees. UNI holders can vote on proposals to improve the platform and receive a portion of the trading fees generated by the platform. UNI has quickly become one of the most valuable cryptocurrencies in the market, with a market capitalization of over $10 billion. Its popularity is due to the success of the Uniswap platform and the growing demand for decentralized exchanges in the cryptocurrency market.
