Circle is a regulated digital asset and payments company best known as the sole issuer of USD Coin (USDC), a fully collateralized dollar stablecoin with a circulating supply of $72.9B as of October 2026, alongside EURC, a MiCA-compliant euro token. Its stablecoin infrastructure connects blockchain settlement with traditional banking rails across more than 20 networks.
Founders and corporate structure
Jeremy Allaire and Sean Neville co-founded Circle in October 2013. Allaire serves as Chief Executive Officer, while Neville served as co-CEO until stepping down from operational leadership in late 2019 to join the board of directors. Circle is headquartered in New York City and trades publicly on the New York Stock Exchange under the ticker CRCL following an initial public offering in June 2025.
Reserve backing and network mechanics
USDC and EURC maintain 1:1 backing with reserve assets. The majority of USDC reserves sit in the BlackRock-managed Circle Reserve Fund, a government money market fund registered under SEC Rule 2a-7 and held in custody at BNY Mellon. CUSIP-level holdings are published daily. Onchain, USDC functions natively across chains including Ethereum, Solana, Avalanche, Base, and Stellar. Circle operates the Cross-Chain Transfer Protocol (CCTP), a native burn-and-mint facility that moves USDC between supported blockchains without third-party wrapped assets.
Fees and platform availability
Institutional clients mint and redeem USDC or EURC at a 1:1 par value through Circle Mint with a 0% issuance and redemption fee, subject to commercial Know Your Business (KYB) checks. Retail users acquire and trade Circle stablecoins through third-party exchanges and DeFi platforms without direct accounts at Circle. Circle Mint supports direct fiat redemption for institutional customers.
Regulatory framework and security record
Circle holds money transmitter licenses across 46 US states, a New York Department of Financial Services BitLicense, an Electronic Money Institution license from the ACPR in France under MiCA, and a Major Payment Institution license from the Monetary Authority of Singapore. Deloitte & Touche conducts monthly point-in-time reserve attestations. Circle faced reserve stress in March 2023, when USDC dropped to $0.87 after the firm disclosed $3.3 billion stranded at the collapsed Silicon Valley Bank. USDC repegged within 72 hours as reserves were shifted to BNY Mellon.
Risks and operational limitations
Circle maintains smart-contract address-blacklisting controls on public networks and can freeze assets at specific addresses. Holders remain exposed to custodial counterparty risk across Circle's commercial banking partners, as shown by the 2023 SVB failure. Unverified users cannot redeem tokens directly for fiat through the issuer and rely on secondary market liquidity.
