What Is USDC?

How It Works

Circle issues USDC on multiple major blockchain networks including Ethereum, Solana, Polygon, and several others. This multi-chain presence means USDC can be sent on whichever network is fastest or cheapest for a given use case — a choice that becomes important when moving large sums.

Every USDC in circulation is matched by $1 held in reserve at regulated US financial institutions or in US Treasury bills. Circle publishes a monthly reserve report attested by a major accounting firm, showing exactly how many USDC are outstanding and exactly what assets are held in reserve. As of 2024, USDC supply has ranged from 25 to 45 billion coins.

Using USDC is straightforward. You connect a bank account to Circle's platform or a regulated crypto exchange, deposit dollars, and receive USDC at a 1:1 rate. You can then send those USDC to any compatible wallet address anywhere in the world in seconds. The recipient can hold USDC as a digital dollar, convert it back to their local currency, or use it for further transactions.

Major financial institutions have integrated USDC into their operations. Visa and Mastercard use USDC for settling certain transactions. PayPal offers USDC on its platform. Increasingly, US government contractors and technology companies are experimenting with USDC payroll for international workers.

Why It Matters

USDC is a working example of what the future of dollar-denominated payments looks like. It demonstrates that a dollar can move globally in seconds, at near-zero cost, 24 hours a day, 7 days a week, on transparent blockchain infrastructure — something that the traditional banking system has never been able to deliver.

For the US government and Federal Reserve, USDC and similar regulated stablecoins extend the reach of the US digital dollar. Every USDC in circulation is a dollar-denominated asset held outside the US but denominated in dollars, reinforcing dollar dominance in global trade. This is why many Washington policy makers view regulated stablecoins favorably — they export dollar hegemony without the US government having to build the infrastructure itself.

For consumers and businesses, USDC represents a concrete, regulated tool for accessing the efficiency of the new financial system without taking on cryptocurrency price risk.

Real-World Example

A pharmaceutical company in Brazil needs to pay a supplier in Singapore. A traditional wire transfer would take 3 to 5 business days, cost $60 to $80 in fees, and pass through at least two correspondent banks. Using USDC, the Brazilian company sends $500,000 USDC directly to the Singapore supplier's wallet address. The transaction confirms in under a minute. The supplier can convert to Singapore dollars immediately or hold USDC as a dollar asset. Total cost: a few dollars in network fees.
