Stablecoin
A cryptocurrency designed to keep a relatively stable value, usually by tracking an asset such as the U.S. dollar.
A stablecoin is a type of cryptocurrency built to reduce price volatility by aiming to match the value of another asset, most commonly a fiat currency like the U.S. dollar. For example, a dollar-pegged stablecoin is intended to trade close to $1. Stablecoins may be backed by cash and short-term assets, overcollateralized with crypto, or managed through algorithmic mechanisms, each with different risks and trade-offs.
Stablecoins matter because they give crypto users a way to move value on blockchains without constantly converting back to bank money or being exposed to large price swings. They are commonly used for trading, payments, remittances, decentralized finance, and holding funds between transactions. A practical comparison is digital cash on a blockchain: it can be sent quickly like crypto, while trying to behave more like dollars than bitcoin. However, stablecoins are not risk-free; their stability depends on reserves, transparency, regulation, market confidence, and the design of the system behind them.
