NOPAL is a lending market on Kamino (Solana), listed as Nest Market NOPAL. Depositors supply NOPAL to the market and earn a variable interest rate paid by borrowers, who post collateral and are liquidated if their loan outgrows the market's limits. The rate floats with utilization — how much of the supplied NOPAL is borrowed at the time — so the market is used to earn on an idle NOPAL balance, or to borrow against collateral without selling it.
