Concerns are growing about the risks associated with Kamino Finance's Multiply product, particularly after the launch of JupSOL and the promotion of its seemingly attractive 40% APY with no depeg risk. Despite the high user influx, the sustainability of these returns is questionable, as the effectiveness of Multiply depends on the borrowing interest rate for SOL being lower than the APY on the staked tokens, a balance threatened by increasing SOL pool utilization which could lead to negative APYs and potential liquidations for users.
