What Circle Does
Circle creates and manages USDC and EURC stablecoins, both redeemable at 1:1 for their corresponding fiat currencies. The company maintains reserves in cash and short-term US government bonds to back these stablecoins. Circle holds the bulk of USDC reserves through the Circle Reserve Fund, which BlackRock manages.
Monthly attestations from Deloitte confirm the adequacy of Circle's reserves against circulating stablecoin supply, providing public transparency on backing.
Target Users and Services
Circle is not a crypto exchange or retail brokerage. Its primary product, Circle Mint, targets institutional users including fintechs, exchanges, payment processors, banks, credit unions, investment firms, and treasury teams who mint and redeem stablecoins at scale.
Beyond stablecoin issuance, Circle provides infrastructure services including Cross-Chain Transfer Protocol (CCTP), Circle Wallets, and the Circle Payment Network. The company is developing Arc, a layer 1 blockchain designed specifically for stablecoins.
Regulatory Compliance
Circle operates under multiple licenses across jurisdictions. In the United States, the company holds an OCC national trust charter, a NYDFS BitLicense, FinCEN MSB registration, and money transmitter licenses across 46 states. In Europe, Circle Mint Europe SAS holds an EMI license under MiCA, granted by France's ACPR in July 2024. Circle reports holding over 55 licenses across the US, EU, UK, Canada, Bermuda, UAE, Japan, and Singapore.
Track Record and 2023 Incident
In 2023, Circle faced a significant challenge when $3.3 billion of its USDC reserves were held at Silicon Valley Bank during its collapse. USDC temporarily lost its dollar peg during this period but recovered. Following that incident, Circle diversified its reserve approach. Circle reports no history of security breaches.

Eligible applicants for Circle Mint include banks, credit unions, payment processors, money transmitters, crypto exchanges, custodians, brokerages, OTC desks, and investment firms. The application process requires submission of company documents, financial or regulatory licenses, and independent audit evidence.
