Yield farming is the practice of staking or lending crypto assets to generate high returns or rewards in the form of additional cryptocurrency. In short, yield farming protocols incentivize liquidity providers (LP) to stake or lock up their crypto assets in a smart contract-based liquidity pool. These incentives can be a percentage of transaction fees, interest from lenders, or a governance token. These returns are expressed as an annual percentage yield (APY). As more investors add funds to the related liquidity pool, the value of the issued returns rise in value.
