A stablecoin is a cryptocurrency designed to maintain a stable price.

Most stablecoins are pegged to the US Dollar:

Stablecoins became the backbone of the crypto economy.

Chapter 3: How Stablecoins Work

Real dollars
Assets (cash equivalents)

Algorithms

This is what keeps the price close to $1.
