USDC (USD Coin) is a stablecoin digital currency backed by the US dollar at a 1:1 ratio, meaning that 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 under the Centre Consortium framework. USDC is widely used in trading platforms, decentralized finance (DeFi), and instant international transfers. It is characterized by high transparency, as its reserves are subject to periodic audits. USDC operates on multiple blockchain networks such as Ethereum, Solana, and Avalanche, making it user-friendly and quick to transfer.
