What is USDC? What is its function? Furthermore, why is its market cap rising against the trend? This article will provide an in-depth analysis of USDC, exploring itsfeatures, uses, differences from USDT, and how to acquire USDC for free, among other aspects.

What is USDC?

USD Coin, or USDC, is a prominent dollar-pegged stablecoin designed to offer a stable digital asset, reducing user exposure to volatile crypto markets.

USDC was launched in 2018 by the Centre Consortium, a collaboration between leading fintech company Circle (CRCL) and the world's second-largest cryptocurrency exchange Coinbase (COIN). This robust backing fueled USDC's rapid, explosive growth post-launch. In just seven years, USDC's market capitalization has approached $80 billion, with near-universal coverage across public chains.

Are USDC and USD the same?

Despite USDC's design to maintain a 1:1 peg with the U.S. dollar, fundamental differences in nature, circulation environment, issuer, and legal status mean they are not entirely the same. Therefore, holding USDC is not fully equivalent to holding U.S. dollars.

Use Category

Specific Function

Description

Practical Application Examples

US Dollar Uses

Asset Preservation

Used as a dollar substitute in high-inflation countries to hedge against local currency depreciation.

Users in Argentina and Venezuela hold USDC for value preservation.

Cross-border Payments

Facilitates fast, low-cost cross-border remittances.

Fintech companies leverage USDC for international settlements.

Everyday Payments

Merchants and Web3 applications accept USDC as a payment method.

Examples include OpenSea NFT marketplace, gaming tips, and subscription services.

Cryptocurrency Uses

Stable Value

Pegged 1:1 to the US dollar, exhibiting virtually no price volatility.

Investors convert BTC/ETH into USDC to mitigate risk.

Medium of Exchange

As one of the primary stablecoins on exchanges, it provides a stable unit of account.

Trading pairs like BTC/USDC and ETH/USDC are available on Binance and Coinbase.

Yield Generation

Interest can be earned through various financial products, including lending, interest-bearing deposits, and liquidity mining.

Aave and Compound offer USDC lending services, while Uniswap and Curve host USDC trading pools.

What are the advantages and disadvantages of USDC?

USDC’s strengths stem primarily from itshigh transparency and compliance, while its drawbacks are linked to itsprivate issuance nature and blockchain technology risks.

Pros

Cons

Industry's Highest Reserve Transparency:Grant Thornton, a top-tier accounting firm, issues monthly third-party audit reports publicly affirming its reserves are full and sufficient.

Centralized Issuer Risk:Its value relies entirely on the creditworthiness of its issuer, Circle, and its held USD reserves. Should Circle face extreme operational issues or have its reserves frozen, USDC might not be redeemable.

Highly Compliant:Issuer Circle is a licensed financial institution regulated by the U.S. Office of the Comptroller of the Currency (OCC) and adheres to strict anti-money laundering (AML) regulations.

Lack of Fiat Currency Protection:It is not insured by the FDIC or SIPC. If the exchange holding USDC goes bankrupt, users may not recover their assets in full.

Safest Reserve Assets:Its reserves are 100% in cash and short-term U.S. Treasuries, bearing almost no credit risk, making it the most conservative stablecoin configuration.

Smart Contract Risk:When used in DeFi protocols, it faces the risk of attacks exploiting vulnerabilities in those protocols' smart contracts.

Preferred by DeFi Ecosystems and Institutions:Due to its transparency and trustworthiness, USDC has become the preferred, often sole, stablecoin collateral accepted by mainstream DeFi protocols. Furthermore, it is the stablecoin partner of choice for traditional giants like Visa and BlackRock entering the crypto space.

Market Share Disadvantage:On some centralized exchanges, its trading pair volume and depth may still lag behind the older Tether (USDT).

What is the price and market capitalization of USDC?

USDC's circulation stands at 76.57 billion tokens, with a market capitalization of $76.56 billion and a market share of 2.60%. It ranks second among all stablecoins, trailing only USDT. Despite their close rankings, a significant disparity exists in their market capitalizations; USDC's volume is less than half that of USDT. Therefore, it is unlikely to unseat USDT's dominant position in the short term.

Observant users may have noticed USDC's price at $0.9998. This indicates that USDC is not precisely 1:1 with the U.S. dollar, but insteadfluctuates slightly around it.Historical events demonstrate that USDC can experience significant volatility under extreme conditions, trading substantially above or below the dollar. For example, in 2023, the U.S. banking crisis — triggered by the collapses of Silicon Valley Bank (SVB) and Signature Bank — caused USDC to depeg from the dollar twice.

Variable

It is crucial to note that while these methods are free, they demand time, attention, and expose participants to market or technical risks. Furthermore, investors should never click on unsolicited links or fall victim to scams asking for upfront USDC, private keys, or seed phrases.

Conclusion

USDC, the world's second-largest stablecoin, touts transparency and compliance as key advantages. While trailing USDT, it aims to lead the "compliant stablecoin" sector, but investors must acknowledge potential risks. Despite its market share still lagging USDT, USDC is poised to become the definitive "compliant stablecoin" as regulations tighten and collaborations with financial institutions deepen. Furthermore, while investors can acquire USDC for free through specific channels, vigilance regarding its potential risks remains crucial.
