$USDC USD Coin (USDC) is a stablecoin pegged to the U.S. dollar, designed to maintain a 1:1 value ratio. It is issued by regulated financial institutions and backed by fully reserved assets, typically held in cash and short-term U.S. government bonds. Built on blockchain technology, USDC operates across multiple networks like Ethereum, Solana, and Polygon, enabling fast, low-cost global transactions. It’s widely used in decentralized finance (DeFi), remittances, and digital commerce. Transparency is key—monthly attestations by accounting firms verify its reserves. USDC aims to combine the stability of the dollar with the efficiency of crypto, fostering trust in digital financial systems.
