Swap USDC at the Best Rate

What is USDC?

USDC is a fiat-backed claim on its issuer, not an algorithmic or crypto-collateralized design. Circle mints USDC when an onboarded customer deposits dollars and burns it on redemption, and the token trades near one dollar because that par mint-and-redeem window exists. The Ethereum contract, deployed in 2018, uses six decimals rather than the usual eighteen.

The token began as a product of the Centre Consortium, founded by Circle and Coinbase. In August 2023 the two companies dissolved Centre, Coinbase took an equity stake in Circle, and Circle became the sole issuer, bringing governance and the smart contract keys in-house. Circle itself listed on the New York Stock Exchange in June 2025.

How USDC works

Institutions with a Circle Mint account wire dollars to Circle and receive newly minted USDC at par; redemptions burn the token and return dollars. Everyone else buys and sells USDC on the open market, where arbitrage against that institutional window holds the price near a dollar.

Most of the reserve sits in the Circle Reserve Fund, an SEC-registered government money market fund managed by BlackRock and custodied at BNY Mellon, holding short-dated Treasury bills and overnight repurchase agreements. The rest is cash at systemically important banks for daily flow. Circle publishes the composition monthly with an attestation by Deloitte & Touche LLP.

USDC is issued natively on more than twenty networks, and Circle's Cross-Chain Transfer Protocol moves it between them by burning on the source chain and minting on the destination, so official deployments do not rely on third-party bridge wrappers.

USDC supply and tokenomics

USDC has no supply schedule, no cap and no burn tied to usage. The amount outstanding is whatever has been minted and not yet redeemed, expanding when demand for on-chain dollars grows and contracting when holders cash out. Scarcity is not the point; full reserve coverage is, and the monthly attestations exist to evidence it.

Under the GENIUS Act, the US federal stablecoin law signed in July 2025, payment stablecoin issuers must hold one-to-one reserves in cash and short-dated Treasuries and may not pay yield to holders. USDC's structure already matched those requirements, which is why holding USDC earns nothing by design.

Who builds USDC

Circle Internet Group is a US financial technology company founded by Jeremy Allaire and Sean Neville in 2013. It runs issuance, reserve management, the mint-and-redeem window and the developer platform around USDC, and it answers to US regulators as a licensed money transmitter and, since June 2025, to public-market reporting obligations as a NYSE-listed company.

Coinbase no longer co-governs the token but remains a distribution partner and shares in reserve interest income under the arrangement announced when Centre closed.

How USDC is governed

There is no token-holder governance. Circle decides which chains get native deployments, sets the terms of minting and redemption, manages the reserve, and controls a blocklist that can stop named addresses from sending or receiving USDC, a power it has used for sanctioned addresses. Holding USDC is trusting Circle and the regulatory regime it operates under.

What people use USDC for

USDC works as the dollar leg of on-chain finance, so most of its activity is settlement rather than speculation on the token itself.

• Quote asset and settlement currency for spot trading on exchanges and automated market makers.
• Collateral and loan asset in lending markets.
• Payments, payroll and remittances that settle in minutes rather than banking days.
• Treasury parking for companies and DAOs that want dollars without a bank transfer.

USDC risks and considerations

USDC concentrates issuer and banking risk. In March 2023, 3.3 billion dollars of its reserves were stuck at the failed Silicon Valley Bank and the token traded well below a dollar until US regulators stepped in to protect the bank's deposits in full; Circle has since shifted reserves toward the Treasury-backed fund structure. The blocklist also means an address can be frozen without its owner's action.

USDC on other networks is only the same asset where Circle issued it natively. Bridged or exchange-wrapped versions carry the bridge's or wrapper's own risk, so verify the deployment for the chain you are using against Circle's published contract list.
