USD Coin (USDC) is a type of stablecoin that is pegged 1:1 to the U.S. dollar, meaning one USDC is always intended to be equal to one USD. It was launched in 2018 by Circle in partnership with Coinbase, and operates on multiple blockchains including Ethereum, Solana, and others. USDC is widely used in the crypto world for trading, savings, and transferring value without the volatility of other cryptocurrencies like Bitcoin or Ethereum. It’s fully backed by reserves, and regularly audited to ensure transparency. USDC plays a key role in decentralized finance (DeFi), offering stability, speed, and global access to digital dollar transactions.
