Stablecoins are digital currencies designed to maintain a stable value, often pegged to traditional assets like the US dollar, making them key players in bridging the gap between cryptocurrency and conventional finance. Their usage has surged, with monthly settlement volumes reaching $1.14 trillion and total market value hitting $170 billion, evidencing their importance in cross-border transactions, market liquidity, and investor protection. Various types of stablecoins exist, including fiat-backed, crypto-backed, and algorithmic, each with unique mechanisms for sustaining their value amid the volatility commonly associated with other cryptocurrencies.
