The Rise of USDC: Secrets of Popularity and Financial Backing

Stablecoins are a crucial component of the cryptocurrency market, playing a key role in various operations, from trading to providing liquidity and lending.

USDC, issued by Circle, ranks as the second-largest stablecoin by market capitalization.

What is USDC?

USDC is a stablecoin pegged to the US dollar, fully backed by highly liquid assets and their equivalents. According to its issuer, USDC can always be exchanged for its underlying asset at a 1:1 ratio.

The token was originally launched by the Centre consortium, which included Coinbase and Circle. In August 2023, Coinbase announced the acquisition of a minority stake from its partner and the dissolution of the consortium.

Since then, Circle has had full control over the stablecoin, though Brian Armstrong’s company continues to act as a co-issuer in practice.

How Does USDC Work?

USDC is issued when users deposit fiat currency into their accounts on the Circle Mint platform. U.S. dollars are exchanged for USDC at a 1:1 ratio, and these transactions are recorded and verified on the blockchain.

In the reverse process, when users redeem USDC for fiat, the stablecoins are removed from circulation to ensure that the supply matches the issuer’s reserves.

Circle Mint is designed for “businesses and wholesale distributors issuing large volumes of USDC.” According to the company, exchanges, institutional traders, digital wallet providers, consumer applications, and banks use the platform.

USDC issuance and redemption are available in 185 countries, with Circle Mint supporting direct bank transfers and SEPA payments. There are no fees for using the platform.

Retail consumers can purchase USDC on the secondary market through centralized and decentralized exchanges, or via P2P transactions.

What Backs USDC?

USDC is a fully backed stablecoin. To maintain its 1:1 peg to the U.S. dollar, the issuer holds reserves equivalent to the circulating token supply. In November 2022, Circle moved these assets into a special fund managed by BlackRock.

Previously, Circle held a small amount of commercial paper, mainly bonds, in its reserves. However, by the time of writing, the reserve structure had changed: 80% of the assets are in short-term U.S. Treasury bonds, and the remaining 20% are in fiat currency.

Fiat reserves are used for immediate redemption operations. Most of these funds are stored in one of the systemically important financial institutions, a measure to reduce risks in case of a bank partner’s potential bankruptcy, similar to the Silicon Valley Bank (SVB) incident.

The issuer also keeps a small portion of the funds with transactional partners to maintain liquidity.

Circle’s reserve fund is regularly audited by external auditors, and the issuer publishes these audit reports on its website. The latest report, as of the time of writing, is dated November 2023, in which Deloitte confirmed that USDC is fully backed.

Circle cannot use the stablecoin’s reserves for corporate purposes. In case of a shortfall in backing, the company is obligated to cover its liabilities using its own assets and, if necessary, by raising external capital.

As of January 25, 2024, the circulating supply of USDC is valued at $25.9 billion, with its backing amounting to $26 billion.

In Which Networks is USDC Available?

USDC was initially launched on the Ethereum blockchain as an ERC-20 token. As of now, the stablecoin is natively supported on 15 networks:

• Ethereum
• Algorand
• Arbitrum
• Avalanche
• Base
• Flow
• Hedera
• NEAR
• OP Mainnet
• Noble
• Polkadot
• Polygon PoS
• Solana
• Stellar
• Tron

Circle plans to expand this list in the future. Additionally, USDC can be transferred to other blockchains via third-party bridges, resulting in wrapped tokens like USDC.e being used.

What is the Cross-Chain Transfer Protocol (CCTP)?

To address liquidity fragmentation in the Web3 ecosystem, Circle developed the Cross-Chain Transfer Protocol (CCTP). This on-chain tool ensures secure and efficient cross-network transactions of the company’s stablecoins.

Here’s how CCTP works:

1. A user initiates a transfer of USDC from one blockchain to another, specifying the amount and the recipient’s address in the destination network. The protocol then burns the relevant amount of tokens in the “source” blockchain.
2. The protocol requests attestation of the transfer from Circle, which must verify the token burn and authorize the issuance of the specified amount of USDC in the destination network.
3. Upon receiving confirmation, the protocol initiates the minting of the necessary token amount in the target blockchain and sends it to the recipient’s address.

Why is the USDC Stablecoin Needed?

The relatively stable price of USDC makes it useful as a payment medium, a protective asset, or a liquidity source. Its characteristics enable various application scenarios.

Hedging Volatility and Market Access

Stablecoins emerged as a solution to the inherent volatility of the cryptocurrency market. Instead of holding unstable assets, investors can convert their funds into more stable ones without exiting the ecosystem’s liquidity.

USDC is supported by most centralized and decentralized trading platforms, enabling quick asset purchases or sales.

Cross-Border Payments and Cross-Chain Interactions

Traditional cross-border transactions between individuals or businesses can be expensive and time-consuming, with some banks taking several days to complete such transfers. USDC offers a much more efficient way to conduct these payments.

Additionally, as previously mentioned, the CCTP protocol allows for the transfer of USDC across different blockchains, making it a convenient tool for value transfer.

Decentralized Finance (DeFi)

Stablecoins are highly sought after by users of various decentralized protocols. They form the backbone of the DeFi ecosystem’s liquidity and act as a “bridge” connecting it to the fiat system.

Investors can use USDC to incorporate the U.S. dollar into their portfolios. Additionally, some protocols and trading platforms allow locking stablecoins to earn interest, further enhancing their utility.

Criticisms and Weaknesses of USDC

Despite its many advantages, USDC has its shortcomings. Notably, since the stablecoin’s market value is influenced by the balance of supply and demand, it can deviate from its nominal peg. This situation is further complicated by Circle’s reliance on banking partners.

For instance, in March 2023, amidst the collapse of SVB, USDC lost its peg to the U.S. dollar, momentarily trading at $0.96.

In response, Circle shifted its focus from local banks to major financial institutions to enhance the stablecoin’s resilience. However, the issuer still depends on the actions of third parties.

Given that USDC is entirely controlled by its issuer, the risks associated with centralization and censorship cannot be ignored. Circle retains the authority to freeze assets on specific addresses, potentially doing so at the request of law enforcement agencies.

Note: As of November 2023, the issuer had frozen over $75 million USDC across 211 addresses.

Another centralization-related risk is the potential for regulatory action against Circle. Should regulators launch investigations and freeze the company’s reserves, USDC holders might lose the ability to convert their digital tokens into fiat currency.

USDC vs USDT

Key Differences

• Backing and Reserves: While both USDC and USDT are backed by U.S. Treasury bonds and fiat currency, USDT’s backing is more diversified. It includes corporate bonds, liquid debt securities, and digital assets, which can add complexity to its reserve structure.
• Audit Frequency: USDC undergoes monthly audits by Deloitte, offering a higher frequency of oversight compared to USDT, which is audited quarterly by BDO Italia. More frequent audits can provide more timely insights into the stability and backing of USDC.

Both USDC and USDT are popular stablecoins, each with its strengths and weaknesses. USDC’s reliance on a more straightforward reserve structure and monthly audits can offer more transparency and potentially greater stability. Conversely, USDT’s broader reserve portfolio might provide additional flexibility but with more complexity and less frequent auditing. Investors and users should consider these factors when choosing between the two stablecoins based on their needs for transparency, stability, and the diversity of reserves.

What Does the Future Hold for USDC?

As of now, USDC’s market capitalization stands at $26.15 billion, making it the second-largest stablecoin by this metric, trailing only behind USDT ($96 billion). USDC’s market dominance is estimated at 20%, compared to USDT’s 74%.

Despite trailing the segment leader, USDC has potential for growth due to Circle’s ongoing efforts to expand the stablecoin’s ecosystem.

Recent Developments

• Expansion of Supported Blockchains: Circle has increased the number of blockchains supporting USDC. Notably, the stablecoin was launched on the Base network by Coinbase, a U.S.-regulated platform whose shares are publicly traded. This move could enhance USDC’s integration and adoption.
• Potential IPO: Circle announced in January 2024 that it has filed for an initial public offering (IPO) with the U.S. Securities and Exchange Commission (SEC). Although details about the IPO have not been disclosed, a public listing could significantly boost USDC’s appeal. It would reduce uncertainty around the issuer and potentially enhance market confidence in USDC.

USDC’s future appears promising with ongoing efforts to broaden its blockchain support and the potential impact of a public offering. If Circle successfully navigates these initiatives, it could narrow the gap with USDT and strengthen USDC’s position in the stablecoin market. Market participants should keep an eye on these developments as they could influence USDC’s growth and adoption in the coming years.

However, like all financial instruments, USDC is not without risks. The centralization of control under Circle and reliance on third-party banking partners introduces potential vulnerabilities, including regulatory scrutiny and market fluctuations. The stablecoin’s ability to maintain its peg to the U.S. dollar is subject to both internal and external factors, which can occasionally lead to deviations from its nominal value.

Looking ahead, USDC’s future appears promising with ongoing efforts to expand its ecosystem and potential impacts from Circle’s planned IPO. As the stablecoin continues to grow and adapt, it may become a more prominent fixture in the cryptocurrency landscape, potentially narrowing the gap with other leading stablecoins like USDT.

For those considering holding funds in USDC, the decision should weigh its benefits—such as stability, liquidity, and transparency—against the inherent risks of centralization and market dynamics. Diversification and staying informed about ongoing developments in the stablecoin space can help mitigate some of these risks and make informed decisions in an ever-evolving financial environment.
