What is a stablecoin?

A stablecoin is a type of crypto asset designed to maintain a stable value relative to a reference asset — typically a fiat currency such as the US dollar or euro. Unlike volatile crypto assets such as Bitcoin or Ether, stablecoins are backed by reserves (cash, short-term treasury securities, or other liquid assets) and are engineered to maintain a one-to-one peg with their reference currency. For B2B payments, stablecoins combine the speed and programmability of blockchain infrastructure with the price stability of fiat currencies.
