In the world of stablecoins, USDC stands as a major player—second only to USDT in market capitalization. While USDT holds the title of the first and most historically significant stablecoin, USDC has carved out its reputation as a pioneer in regulatory compliance.
This compliance means that Circle, the issuer behind USDC, operates under government supervision, follows relevant regulations, and provides monthly reserve attestation reports verified by a Big Four accounting firm.
Common criticisms directed at USDT—such as lack of full compliance, incomplete audits, and regulatory opacity—do not apply to USDC. That said, both are centralized stablecoins and share inherent centralization risks.
As of mid-2025, USDC's market capitalization exceeds $61 billion, firmly securing its position as the second-largest stablecoin.
Circle went public on the New York Stock Exchange (NYSE) on June 5, 2025, under the ticker symbol CRCL. The IPO raised over $1 billion, valuing the company at approximately $6.9 billion and marking a milestone as the first stablecoin issuer to list on a traditional stock exchange.
This article offers a comprehensive introduction to USDC and Circle, helping you better understand its features, evaluate its risks, and compare it with other stablecoins. We also include guidance on how to safely acquire USDC and avoid common scams.

Understanding USDC and Its Ecosystem
USDC is a U.S. dollar-pegged stablecoin, meaning its value is designed to remain constant at $1. Stablecoins are cryptocurrencies whose values are tied to traditional fiat currencies, making them far less volatile than other digital assets.
As of mid-2025, the total stablecoin market is valued at approximately $247 billion. USDC, with over $61 billion in market capitalization, is the clear runner-up, though still about 2.5 times smaller than USDT.
USDC was launched in October 2018 through a collaboration between Coinbase and Circle. Coinbase, founded in 2012, is one of the largest and first publicly-listed cryptocurrency exchanges in the U.S. Circle, established in 2013, specializes in blockchain-based financial services and was the first company to receive a BitLicense from the New York State Department of Financial Services. While both companies developed USDC, Circle is the official issuer.
Circle: The First Publicly-Listed Stablecoin Issuer
On June 5, 2025, Circle began trading on the NYSE under the symbol CRCL. This landmark event made it the first stablecoin issuer to go public on a major traditional exchange. The IPO raised more than $1 billion and reflected a company valuation of around $6.9 billion—signaling a significant step toward the integration of crypto and conventional finance.
Circle also has connections to the global tech community. In 2022, it acquired the Taiwanese blockchain security firm CYBAVO, integrating its technology to enhance Circle’s own security infrastructure.
Beyond stablecoins, Circle also operates Circle Ventures, a corporate venture fund aimed at supporting projects that build on or utilize USDC and other Circle-issued currencies. Its portfolio includes projects like Maple Finance, LayerZero, Sui, DeBank, and Hyperlane—spanning areas such as real-world assets (RWA), interoperability, and blockchain infrastructure.
How USDC Maintains Its Peg: Reserves and Redemption
Each USDC in circulation is backed by an equivalent amount of U.S. dollar-denominated assets. These reserves are held in the Circle Reserve Fund, a registered money market fund managed by BlackRock. A Big Four accounting firm, Deloitte, provides monthly attestations regarding the adequacy and composition of these reserves.
The reserve assets consist of highly liquid instruments: short-term U.S. Treasuries, overnight repurchase agreements, and cash. This ensures that even during periods of high redemption demand, Circle can meet withdrawal requests promptly.
The redeemability of USDC for U.S. dollars is fundamental to its peg maintenance. Should the market price of USDC deviate below $1, arbitrageurs can buy USDC at a discount and redeem it for full value, thereby pushing the price back to its peg.
Circle provides daily updates on the net asset value (NAV) and performance of its reserve fund. Monthly attestation reports are available for public review on the company’s transparency page.
USDC Circulation and Distribution: A DeFi Favorite
According to on-chain data from platforms like DeFiLlama, USDC’s circulating supply was around $61 billion as of mid-2025, distributed across more than 100 blockchains.
The top three blockchains by USDC circulation are:
- Ethereum — approximately 60%
- Solana — approximately 13%
- Base — approximately 6%
Although USDT is the largest stablecoin by overall market cap, USDC dominates certain blockchain ecosystems. For example, on Solana, USDC constitutes about 72% of all stablecoin activity. On Base, that share exceeds 90%.
This higher market share within specific chains means USDC is often more deeply integrated into decentralized applications—including decentralized exchanges (DEXs), lending protocols, and cross-chain bridges. This can sometimes translate into higher yield opportunities for holders, whether in DeFi protocols or through exchange-based earning products.
Is USDC Safe?
In short: USDC is issued by a compliant, transparent company that provides regular attestations regarding its full reserve backing. It is the second-largest stablecoin and is generally considered safe. That said, no cryptocurrency is without risk, as demonstrated during the March 2023 Silicon Valley Bank incident when USDC temporarily depegged by nearly 13%. It recovered within days.
Several factors contribute to USDC’s trust model:
- The Circle Reserve Fund is managed by BlackRock and consists of highly liquid assets.
- Monthly attestation reports are provided by Deloitte and are publicly accessible.
- In June 2025, Circle became a publicly-traded company, subjecting it to additional regulatory and disclosure requirements.
Key Factors in Evaluating Stablecoin Safety
- Who is the issuer?
For centralized stablecoins, trust in the issuer is crucial. Circle is a regulated entity with multiple international licenses. - How is the peg maintained?
USDC uses a reserve-backed model where each token is backed by real assets and can be redeemed 1:1 for U.S. dollars. The critical questions are: Are reserves sufficient? Are they liquid? Is the attestation trustworthy?
Is Circle Compliant? Which Licenses Does It Hold?
Circle was founded in 2013 and is the first company to have received a BitLicense from New York state. As of 2025, it is also a publicly-traded company. Circle holds regulatory approvals across several jurisdictions, including the U.S., U.K., Singapore, France, and Bermuda. A full list of licenses can be found on its official website.
Compliance matters because centralized stablecoins require trust in a single entity. Regulatory oversight reduces (but does not eliminate) the risk of malpractice, such as unauthorized minting or insufficient reserves.
U.S. Regulatory Development: The GENIUS Act
In 2025, the U.S. Congress advanced the GENIUS Act (Guaranteeing Essential Neutrality in the Issuance of Stablecoins Act), which proposes a federal regulatory framework for stablecoins.
Key provisions include:
- Stablecoin issuers must obtain federal approval.
- Reserves must consist of high-liquidity assets like U.S. Treasuries and cash.
- Regular reserve reporting and public disclosures are mandatory.
- Issuers may not pay interest on reserves to general users.
- Anti-money laundering (AML) and sanctions compliance are required.
Based on publicly available information, USDC already meets many of the proposed requirements, including high-liquidity reserves and monthly attestations. Should the bill become law, Circle will likely need to undergo additional registration and compliance steps.
Breaking Down USDC’s Reserves
When evaluating a centralized stablecoin’s reserves, three elements are essential:
- Are reserves fully backed?
As of the latest report, USDC’s reserves slightly exceed circulating supply—$61.3 billion in reserves for $61 billion in USDC. - Are reserve assets liquid?
USDC reserves are held in cash, short-term U.S. Treasuries, and overnight repurchase agreements—some of the most liquid assets available. - Is the attestation credible?
Deloitte, a Big Four accounting firm, provides monthly attestation reports. These can be accessed publicly on Circle’s transparency page.
