$USDC USD Coin (USDC) is a stablecoin pegged 1:1 to the U.S. dollar, ensuring price stability in volatile crypto markets. Issued by Circle, it’s backed by cash and U.S. Treasury bonds, operating as an ERC-20 token on Ethereum and other blockchains. In trading pairs like USDC/BTC or USDC/ETH, USDC acts as a stable base, allowing traders to hedge against volatility, settle trades, or transfer value across exchanges without converting to fiat. Its transparency, regulatory compliance, and high liquidity make it a preferred pair on platforms like Coinbase and Binance, facilitating seamless decentralized finance (DeFi) and cross-border transactions.
