Yearn.finance (YFI) is a decentralized finance (DeFi) protocol designed to automate the generation of income from cryptocurrency assets on the Ethereum platform. YFI is the native token of the Yearn.finance ecosystem and is used to govern the protocol. Yearn.finance's main goal is to optimize returns from staking, borrowing and providing liquidity by transferring user assets between different DeFi protocols with the best interest rates. Through a sophisticated set of smart contracts and automation, Yearn.finance allows users to maximize returns on their investments while minimizing the need for active management.
