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