$USDC USD Coin (USDC) is a regulated, fiat-backed stablecoin pegged 1:1 to the U.S. dollar. Issued by Circle, each USDC is backed by cash and short-term U.S. Treasury bonds, with reserves verified through monthly audits. Launched in 2018 by the Centre Consortium (Circle and Coinbase), USDC has become a cornerstone of the digital economy, facilitating fast, low-cost global transactions across multiple blockchain networks, including Ethereum, Solana, and Polygon. Its transparency and regulatory compliance have made it a preferred choice for decentralized finance (DeFi), cross-border payments, and digital commerce. As of April 2025, USDC's circulation reached $60 billion, reflecting its growing adoption and trust among users. (MEXC Blog, Token Fest, Best Bitcoin & Crypto Payment Processor)
