$USDC USD Coin (USDC) is a stablecoin pegged to the U.S. dollar at a 1:1 ratio, ensuring price stability. Launched in 2018 by Circle and Coinbase, it operates on blockchains like Ethereum, Solana, and Algorand. USDC is backed by fully reserved assets, primarily cash and short-term U.S. Treasury bonds, held in regulated financial institutions. Monthly attestations by independent auditors verify these reserves. USDC enables fast, low-cost transactions for payments, remittances, and DeFi applications. Its transparency, regulatory compliance, and interoperability make it a trusted digital dollar, widely adopted in crypto exchanges, wallets, and decentralized finance protocols.
