$USDC USD Coin (USDC) is a regulated, fully-backed stablecoin issued by Circle and governed by the Centre Consortium. Each USDC token is backed 1:1 by U.S. dollar reserves held in U.S. banks or short-term U.S. government securities, ensuring stability and transparency. Launched in 2018, USDC operates on multiple blockchains, including Ethereum, Solana, and Avalanche, enabling fast, low-cost digital payments. It is widely used in decentralized finance (DeFi), trading, remittances, and business transactions. Monthly audits by third-party firms verify the reserve backing. USDC aims to combine the benefits of crypto—speed, transparency, programmability—with the stability of the U.S. dollar.
