Kamino vault farm rewards: 2.81% APY
This vault has a liquidity farm attached to it. Your deposit is staked in the farm automatically, so you earn its reward tokens alongside the ordinary lending interest, with nothing extra to set up. Kamino's own documentation notes that farm rewards are shown separately from a vault's headline APY, so this rate is genuinely on top of the yield the vault already quotes. Farm rewards are funded for a set period and can change or stop when that funding runs out.
