A Stablecoin is a type of digital money (cryptocurrency) that is designed to always be worth the same as a real-world currency — usually the U.S. dollar.
Popular USD-backed stablecoins
- USDT (Tether): The most widely used stablecoin, backed by cash and Treasuries, primarily used for crypto trading worldwide.
- USDC (USD Coin): Issued by Circle, fully backed and transparent, popular in DeFi and institutional finance.
- DAI: A decentralized, crypto-collateralized stablecoin managed by MakerDAO. Maintains its $1 peg through smart contracts without holding actual USD.
- PYUSD (PayPal USD): Backed by U.S. Treasuries and issued by Paxos for PayPal, targeting retail users for digital payments.

Do stablecoins have to be USD-backed?
Technically no. A stablecoin is a representation of any asset that is 1:1 backed. Some examples of non-USD stablecoins include those representing gold, silver, and other currencies around the world.
