Stablecoins are perhaps the most significant development in digital assets, a linkage between the financial world of old and quickly developing world of cryptocurrencies. Stablecoins are distinct from other popular cryptocurrencies such as Bitcoin or Ethereum in that they are meant to be of equal value, usually a percentage of a fiat currency such as the U.S. dollar or euro. Such stability allows them to function as a sound medium of exchange, store of value, cross-border transaction and decentralized finance (DeFi) use medium. Stablecoin's global presence also raised fundamental questions about the regulation of stablecoins and thus global financial centers, international bodies, and national regulators have come together and established standards to keep systemic risks in check, protect consumers, and facilitate responsible innovation.
