$USDC USD Coin ($USDC) is a popular regulated stablecoin backed 1:1 by U.S. dollars, issued by Circle and governed by Centre Consortium. It runs on multiple blockchains including Ethereum, Solana, and Polygon, making it widely accessible for DeFi, trading, and payments. Unlike volatile cryptocurrencies, USDC offers price stability, making it ideal for remittances, cross-border payments, and holding value in crypto wallets. Institutions trust it for its transparency, as reserves are regularly audited. With growing adoption, USDC bridges traditional finance and crypto, but users should still verify platform risks and ensure they're interacting with trusted services when using or storing USDC.
