An algorithmic stablecoin seeks to maintain a price target using programmed supply changes or economic incentives. The term usually emphasizes reliance on these mechanisms instead of full backing by independent reserve assets. Hybrid designs can combine algorithmic rules with partial collateral; using smart contracts alone does not make every stablecoin algorithmic.
How stabilization is attempted
A design may expand supply when its price rises above target and encourage contraction when it falls below. Some systems adjust holder balances through rebasing. Others offer conversion into a related token or promises of future tokens to encourage participants to remove stablecoins from circulation.
These mechanisms rely on demand, credible conversion rules, and participants willing to transact. An algorithm can change balances or exchange terms, but it cannot force buyers to value a token at the intended price.
Why confidence matters
If holders rush to exit, the token used to absorb redemptions may also lose value. Issuing more of that token can deepen selling pressure, creating a self-reinforcing decline commonly called a death spiral.
A stated peg is therefore an objective, not a guaranteed redemption value. Assessing the design requires examining actual reserves, their independence from the issuer's own token, redemption constraints, and how the mechanism behaves when demand contracts.
