Seigniorage

In the case of algorithmic stablecoins, seigniorage is generated when the stablecoin's value rises above its peg (e.g., $1). The protocol can then mint new tokens and sell them on the open market, generating revenue. This revenue is used to maintain the stablecoin's peg to its target value. If the stablecoin's value falls below its peg, the protocol can buy back tokens, reducing the supply and helping to restore the peg.
