Peg Maintenance Mechanism

A peg maintenance mechanism refers to the set of algorithmic rules and economic incentives used to keep a stablecoin's value aligned with its target asset, usually the US dollar. These mechanisms often involve arbitrage opportunities that arise when the stablecoin price deviates from its target.

If the price rises above the peg, the protocol incentivizes minting to increase supply and lower the price. Conversely, if the price falls below the peg, the protocol encourages burning or redeeming stablecoins to decrease supply and push the price back up.

Some systems use secondary markets, interest rate adjustments, or collateral buybacks to reinforce this stability. Effective mechanisms are vital for trust, as they ensure users can always exit their positions at the intended value.

Without these, the stablecoin would lose its utility as a reliable medium of exchange.
