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 bank reserves 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 periodic audits. USDC operates on multiple blockchain networks such as Ethereum, Solana, and Avalanche, making it easy to use and fast to transfer.
