A stablecoin is a type of cryptocurrency that is pegged to the value of an underlying asset, such as the US dollar. The value of a stablecoin is designed to remain relatively stable, as opposed to the highly volatile prices of other cryptocurrencies like Bitcoin and Ethereum. This makes stablecoins a popular option for trading, as well as for use as a form of digital currency for making payments. Examples of stablecoin include Tether (USDT), DAI, USDC, BUSD, etc.
