Circle’s trading operations primarily revolve around its stablecoin, USD Coin (USDC), a digital dollar backed 1:1 by U.S. dollar reserves. It enables real-time payments and settlements across crypto and traditional financial networks. Circle facilitates liquidity, market making, and treasury operations to maintain USDC’s peg and manage demand. The company also supports institutional trading through APIs, and partnerships with exchanges and financial institutions. Circle’s infrastructure is designed for transparency and compliance, including regular audits of its reserves. As a bridge between traditional finance and blockchain, Circle plays a critical role in crypto markets and cross-border payment ecosystems.
