$USDC Coin is a fully-backed stablecoin pegged to the U.S. dollar, meaning each USDC is backed 1:1 by real dollar reserves. Launched in 2018 by Circle and Coinbase, USDC provides a bridge between traditional finance and the crypto world. Unlike volatile cryptocurrencies like Bitcoin, its stability makes it ideal for trading, savings, and remittances. It's built on multiple blockchains including Ethereum, Solana, and Avalanche, enabling fast, low-cost transfers globally. USDC’s transparency is notable—Circle publishes monthly attestation reports to verify reserves. Its rapid adoption in DeFi and Web3 ecosystems highlights how stablecoins are reshaping digital finance.
