yearn.finance is a group of protocols running on the Ethereum blockchain that allow users to optimize their earnings on crypto assets through lending and trading services. One of a number of emerging decentralized finance (DeFi) projects, yearn.finance provides its services using only code, removing the need for a financial intermediary like a bank or custodian. To do this, it has built a system of automated incentives around its YFI cryptocurrency.
