$USDC USDC (USD Coin) is a stablecoin backed by the US dollar, launched in collaboration between the American company Circle and Coinbase, representing a centralized stablecoin. USDC is pegged to the US dollar at a 1:1 ratio; for every USDC issued, there must be an equivalent amount of US dollars or highly liquid assets held in reserve to ensure its stable value. As a stablecoin, USDC is widely used in cryptocurrency trading, cross-border payments, DeFi ecosystems, and digital asset settlements, providing users with a stable and efficient medium of exchange. USDC has high transparency, with reserve funds being audited regularly, but it also faces risks of being frozen or affected by policies due to its regulation by centralized institutions.
