The stability system in the protocol deterministically expands and contracts the PDD supply to maintain PDD's peg to 1 MATIC token. So, in short, the ideal balance is the target of 1 PDD to be pegged to 1 MATIC. PolyDogeDAO is designed by the PolyDoge team as an algorithmic stablecoin that specifically uses an 'algorithmic central protocol' approach to manage the supply of PolyDogeDollar tokens according to a predetermined logic. The algorithm is in charge of balancing the PolyDogeDollar supply to fluctuating demand, ensuring that the token price remains relatively stable.
