Read the API docsUSDC is a fully collateralized US dollar stablecoin, meaning each token is designed to be worth exactly one US dollar and is backed by dollar-denominated reserves. It serves as a digital stand-in for dollars, allowing individuals, businesses, and financial institutions to move US dollar value across cryptocurrency networks without the price swings associated with other digital assets. The project frames itself as infrastructure for a more open global economy, removing friction from cross-border value transfer in the same way that email standardized communication between different mail systems.
USDC is issued by a regulated entity and is redeemable one-for-one for US dollars, with reserves held in cash and short-duration US government instruments that are regularly attested by third parties. The token itself does not rely on a single blockchain or consensus algorithm; it exists across multiple networks simultaneously, including Solana, Avalanche, Polygon, Arbitrum, Near Protocol, and Celo, among others, with a block time recorded as zero in this dataset reflecting its multi-chain, non-native nature. Users acquire or redeem tokens through authorized partners, and the peg is maintained by that direct redemption mechanism rather than by algorithmic incentives.
The data stored here does not include a fee stream attributable to USDC holders or stakers, which is consistent with how fully collateralized fiat-backed stablecoins typically operate — the issuer may earn yield on the underlying reserves, but that revenue does not flow to token holders and no such figure is provided here. Because there is no protocol fee revenue recorded, fee-based valuation measures that this site might apply to other assets are not applicable to USDC. The stablecoin circulating supply stands at 73,943,607,266.41 on a point-in-time basis, and that supply grew by approximately 1.97 percent over the trailing 30 days, which gives a sense of demand for the instrument over that period.
