As part of the decentralized finance industry, Yearn.finance is a decentralized ecosystem of aggregators that utilize lending services including Aave, Compound, Dydx, and Fulcrum to optimize users’ token lending. When tokens are deposited into Yearn.finance, they are converted into yTokens. YFI is Yearn.finance’s governance token, which is distributed to users who provide liquidity with certain yTokens. Andre Cronje, the founder of Yearn.finance, believes YFI will strive to be the most decentralized token.
