yearn.finance (YFI)

yearn.finance is a decentralized finance (DeFi) platform which aims to perform a host of functions such as aggregated liquidity, leveraged trading, and automated marketing making. YFI is the native token in the yearn. finance platform. Users can earn it by contributing liquidity to yearn.finance's liquidity pool and use the token for platform governance.

In the current iteration of yEarn, the flagship product is its automated yield farming contract, called vaults. Each vault allows users to deposit a particular token, and the protocol automates yield farming strategies by moving providers' funds between platforms such as dYdX, Aave, and Compound. Several smaller investors can deposit their tokens in yEarn, pooling funds to form one large investor, thereby netting and minimizing transaction fees associated with depositing funds into a pool,

Andre Cronje created yEarn Finance to automate the process of manually moving funds between DeFi money markets to secure the best lending rate. iEarn Finance, as it was then called, was released to the public. What started as a yield aggregation instrument evolved into a platform that supported automated liquidity mining strategies.
