#StablecoinPayments USDC (USD Coin) is a stablecoin backed 1:1 to the US dollar, launched in 2018 by Circle in partnership with Coinbase. Each USDC in circulation is supported by reserves in dollars or highly liquid assets, audited monthly by third parties to ensure transparency. Operating on the Ethereum blockchain (as an ERC-20 token), but also having versions on Solana, Algorand, and other networks, USDC offers fast transfers between exchanges, wallets, and DeFi applications. It is widely used to minimize volatility risk, facilitate international payments, and provide liquidity in lending protocols and yield farming. With a supply exceeding US$ 28 billion and growing institutional adoption, USDC is consolidating as a pillar of the crypto ecosystem.
