$USDC USD Coin (USDC) is a fully-backed digital stablecoin pegged to the U.S. dollar, developed by Circle and governed by the Centre consortium. It is widely used for fast, secure, and low-cost transactions on blockchain networks like Ethereum, Solana, and others. Each USDC is backed 1:1 by cash or short-term U.S. Treasury bonds, with reserves held in regulated financial institutions. Regular audits ensure transparency and trust. As a stablecoin, USDC combines the stability of the dollar with the efficiency of crypto, making it ideal for payments, trading, DeFi, and remittances, while avoiding the volatility common to traditional cryptocurrencies.
