USD Coin (USDC) is a stable digital currency backed by the US dollar at a 1:1 ratio, meaning that each unit is equivalent to one dollar stored in a bank reserve or equivalent cash assets. USDC was launched in 2018 by Circle in collaboration with Coinbase, and it operates on multiple blockchain networks such as Ethereum, Solana, and Polygon.

USDC is characterized by transparency, as it undergoes regular audits to ensure that the necessary reserves are in place to support it. It is used for payments, financial transfers, trading, and funding decentralized projects (DeFi). Due to its stability and reliability, it has become one of the most widely used stablecoins in the cryptocurrency market.
