Malt is an algorithmic stablecoin protocol initially deployed on Polygon that carries out privileged arbitrage on itself to keep the price stable. Profit generated via this arbitrage is then split between directly paying LPs and bolstering peg defenses. As an LP all you have to do is create Malt LP and bond your LP tokens into the Malt contract. You will now start receiving a pro-rata share of all the profit made via the protocol arbitrage.
