USDC (USD Coin) is a digital stablecoin backed by the US dollar at a 1:1 ratio, meaning each unit is equivalent to one US dollar held in a bank reserve or equivalent cash assets. It was launched in 2018 by Circle in collaboration with Coinbase as part of the Centre Consortium. USDC is widely used on trading platforms, decentralized finance (DeFi), and instant international transfers. It features high transparency, as its reserves are subject to regular audits. USDC operates on multiple blockchain networks such as Ethereum, Solana, and Avalanche, making it easy to use and quick to transfer.
