USDC is a dollar stablecoin jointly issued by Circle and Coinbase, backed by a 1:1 dollar reserve, ensuring stability in value. Its core advantages lie in high transparency and strong compliance, with regular third-party audits and public reserve reports, supervised by U.S. regulatory agencies. USDC is widely used in DeFi, cross-border payments, and asset hedging, especially during market volatility, where it is seen as a reliable value anchoring tool. Although there are trust risks associated with relying on centralized institutions to manage reserves, its strict regulatory framework and instant exchange capabilities make it a robust choice among mainstream stablecoins, continuously promoting the integration of the crypto ecosystem with traditional finance.
