Stablecoin
Most cryptocurrencies swing in price by the hour. Stablecoins solve that by pegging (fixing) their value to a reference asset, most commonly the US dollar. Because the target price is always $1.00, stablecoins function as a relatively steady medium of exchange inside the crypto ecosystem without converting back to traditional bank accounts.

Reserve type is the critical distinction between stablecoin varieties. Fiat-backed stablecoins hold actual dollars or short-term government securities in a custodian bank — every token issued is supposed to be redeemable for a real dollar. Crypto-backed stablecoins use other cryptocurrencies as collateral, usually requiring more than $1 of collateral per $1 of token to absorb price swings. Algorithmic stablecoins rely on code and incentives rather than hard reserves to defend the peg — a model that has proven fragile in practice. See depeg for what happens when the mechanism fails.
A common confusion: "stable" refers only to the price target, not to the safety of the issuer or the quality of its reserves. Traders typically inspect audit reports and reserve breakdowns because a fiat-backed stablecoin is only as sound as the assets actually held.
