The Origin OS ARM is a vault that purchases Origin's OS when it goes below its S peg and puts it through Origin's redeem queue to earn an arbitrage profit. The S is then recycled back to purchase more OS. If purchasing OS below peg is not possible, the vault lends the S to a Silo market to earn a baseline yield. Since its inception, the OS ARM has handled millions of dollars in volume. The OS ARM was modeled after the Lido stETH ARM.
