$USDC USDC is a dollar stablecoin jointly issued by Circle and Coinbase, supported by a 1:1 dollar reserve to ensure stable value. Its core advantages lie in high transparency and strong compliance, regularly audited by third parties and publicly reporting reserves, under the supervision of U.S. regulatory agencies. USDC is widely used in DeFi, cross-border payments, and asset hedging, especially viewed as a reliable value anchoring tool during market volatility. Although there are trust risks associated with centralized institutions holding reserves, its strict regulatory framework and instant redemption capability make it a robust choice among mainstream stablecoins, continuously promoting the integration of the crypto ecosystem with traditional finance.
