Yield Farming
Yield Farming is a strategy within the DeFi ecosystem that encourages the locking up or staking of cryptocurrency assets to earn rewards, often in the form of interest or governance tokens. This method gained traction in the summer of 2020, known as the 'DeFi Summer,' with the emergence of platforms like Uniswap, Sushiswap, Yearn, and Yam Finance. Participants contribute their crypto assets to liquidity pools governed by smart contracts, which in turn utilize these assets for lending or facilitating transactions, rewarding contributors with a portion of transaction fees, interest, or new tokens through a process known as 'liquidity mining.' Rewards are typically quantified as an annual percentage yield (APY).
Sources of Yield
In yield farming, the returns primarily originate from transaction fees, interest payments on lent out assets, and the distribution of governance tokens, which may represent a stake or voting rights in the DeFi protocol's governance. The mechanism encourages the provision of liquidity to the market, facilitating smoother transactions and lending processes within the DeFi ecosystem.
Characteristics of Yield Farming
True yield farming operations are characterized by their permissionless and trustless nature, requiring no intermediaries or central authorities. They are typically built on decentralized blockchains like Ethereum or Binance Smart Chain and involve participation in automated market makers (AMMs) such as Uniswap and Curve Finance. This strategy allows participants to earn various forms of yield simultaneously, including trading fees, interest from lending, and potentially valuable governance tokens.
