USDC is a stable cryptocurrency (stablecoin) launched in 2018 by the Centre Consortium, founded by Circle and Coinbase. Pegged to the US dollar at a 1:1 ratio, its value remains relatively stable, supported by reserves of dollars and government bonds held in regulated financial institutions. This makes it attractive for transactions, savings, or as a refuge in the volatility of the crypto market. It operates on multiple blockchains, including Ethereum, Solana, and Polygon, allowing for fast and cheap transfers compared to traditional banking systems. It is used in decentralized finance (DeFi) for lending, staking, or liquidity on platforms such as Uniswap. Transparency is a strong point: Circle publishes audited monthly reports confirming the reserves backing the issued coins. The popularity of USDC has grown due to its stability and integration with payment platforms like Visa or Stripe, facilitating conversion between fiat and crypto currencies. It is also a key tool in global trade, enabling cross-border transfers without costly intermediaries. However, its centralization raises questions: Circle can freeze funds in certain cases, unlike decentralized cryptocurrencies such as Bitcoin. In 2025, USDC remains the second largest stablecoin by market capitalization, with growing adoption in emerging economies. Critics highlight the risks of strict regulation and dependence on the dollar, but supporters see it as a bridge between traditional finance and a decentralized future.
