$USDC USD Coin (USDC) is a type of cryptocurrency known as a stablecoin, meaning its value is pegged to the U.S. dollar at a 1:1 ratio. It was launched by Circle and Coinbase and runs on several blockchains, including Ethereum, Solana, and Polygon. USDC is widely used for fast, low-cost transactions, trading, and decentralized finance (DeFi) applications. Since its value remains stable compared to volatile cryptocurrencies like Bitcoin or Ethereum, it is often used as a safe place to store value in crypto markets. Every USDC token is backed by fully reserved assets and is regularly audited for transparency.
