An algorithmic stablecoin is a stable cryptocurrency whose supply is regulated by algorithms rather than fully backed by reserves of cash or other assets. Smart contracts automatically expand or shrink the supply to hold a target value, usually one US dollar, and some designs are only partly collateralized.
Why it matters
Supporters see algorithmic designs as a way to build a stable, decentralized currency without relying on bank accounts full of reserves. The weak point is confidence: the peg holds only while traders are willing to buy the coin, or a linked token, when the price slips. In a panic that demand can vanish, the mechanism may issue large amounts of the linked token, and the peg can break entirely. Several algorithmic stablecoins have lost their peg this way, so users look closely at what, if anything, backs a coin.
Example
Imagine a coin designed to trade at one dollar. When demand pushes its price above that target, the protocol creates new coins and sells or distributes them, and the extra supply pulls the price back down. When the price slips below the target, the protocol offers a reward, such as a discounted bond or a swap into a linked token, to holders who remove coins from circulation. Shrinking the supply this way is meant to let the price recover.
