Stablecoins in Spotlight as U.S. Begins to Lay Ground for Cryptocurrency Rules

Stablecoins are a form of digital currency issued by companies such as Tether Ltd. and Circle Internet Financial Inc. and designed to combine the stability of national currencies like the dollar with the ability to trade quickly online like bitcoin.
