USD Coin (USDC) is a fully-backed, regulated stablecoin pegged 1:1 to the U.S. dollar. Launched in 2018 by Circle and Coinbase, USDC provides a reliable, transparent, and fast digital dollar for global transactions. It's issued on multiple blockchains, including Ethereum, Solana, and Avalanche, enabling wide compatibility across decentralized finance (DeFi) platforms. Each USDC is backed by dollar-denominated assets held in regulated financial institutions, with regular attestations for transparency. Designed for stability and compliance, USDC is used for trading, remittances, and payments, bridging traditional finance and crypto. Its stability and trustworthiness have made it a cornerstone in the digital asset ecosystem.
