CRV or Curve Finance is the Decentralized Exchange (DEX) built in Ethereum that enables P2P trading between cryptocurrencies, similar to Uniswap or others DEX. However, Curve is made for Stablecoin trading, such as DAI, USDT, or USDC.
Curve uses Automated Market Maker (AMM) to manage liquidity on the exchange. The users can lock their coins in the system up to 4 years to help provide liquidity on the platform and earn reward in the form of CRV, the more trading made on the platform, the more reward the user will earn.
Curve was launched in January 2020, during the time of DeFi Boom, and was very well welcomed by the crypto community.
In August 2020, Curve launched the CurveDAO, the Decentralized Autonomous Organization (DAO) that enables the community to manage the platform.
