USDC

USDC is a stablecoin issued by Circle on multiple blockchains, primarily Ethereum and Solana, with full USD backing held in reserve accounts. The token functions as a settlement layer and liquidity bridge across decentralized exchanges, lending protocols, and blockchain networks. Each USDC unit maintains a 1:1 peg to the US dollar through reserve management and regular attestations, operating without algorithmic mechanisms or collateralization requirements.

Traders monitor USDC because it anchors liquidity depth across spot and derivatives markets—most major trading pairs denominate against USDC rather than other stablecoins, making it the pricing reference for volatility analysis. Supply fluctuations signal institutional inflows and outflows, while USDC's cross-chain deployment patterns reveal capital migration between ecosystems. Its role as the primary settlement asset in perpetuals markets and as collateral in lending protocols makes its reserve composition and circulation metrics material to understanding systemic leverage and counterparty risk exposure.
