How Does the “Peg Stability Module” (PSM) Help Maintain DAI’s 1 Dollar Peg?

The PSM allows users to swap specific approved centralized stablecoins (like USDC) for newly minted DAI at a 1:1 ratio, and vice-versa. This mechanism ensures that if DAI trades above 1 dollar, users can arbitrage by minting cheap DAI and selling it.

If DAI trades below 1 dollar, users can buy cheap DAI and redeem it for 1 dollar of the centralized stablecoin, thus anchoring the price back to the target.
