Circle Complete Guide: How USDC Is Reshaping Digital Payments

By: WEEX|2025/07/09 17:00:05

The emergence of stablecoins has transformed digital value transfer fundamentally. Among these innovations, Circle's USDC stands as a significant development in the cryptocurrency landscape. Following Circle's landmark IPO that saw its stock price surge 258% in its first week of trading, investors and users want to understand what Circle is, how USDC functions, and what this means for digital finance.

This guide explores Circle and USDC – from operational mechanics to use cases – providing insights for both newcomers and experienced users.

What Is Circle and How Does It Relate to USDC?

Circle Internet Financial is a global fintech company founded in 2013 that initially focused on peer-to-peer payments before becoming the principal issuer of USD Coin (USDC), the second-largest stablecoin by market capitalization.

USDC is a digital currency fully backed by US dollar assets, maintaining a stable 1:1 peg with the US dollar. As of 2025, USDC's market capitalization exceeds $60 billion, representing approximately 29% of the global stablecoin market, second only to Tether's USDT ($153.8 billion).

Many confuse Circle (the company) with USDC (the stablecoin product). Circle operates as both the issuer of USDC and a financial services platform offering payment, treasury, and financial infrastructure solutions.

How Does Circle's Business Model Work?

Circle has developed a straightforward business model:

Reserve-Backed Structure: For each USDC token issued, Circle maintains an equivalent amount of US dollars in reserve, primarily invested in short-term US Treasury bills and cash equivalents.
Revenue Generation: Circle generates revenue primarily from the interest earned on these reserves. In 2024, approximately 99% of Circle's $1.68 billion revenue came from reserve interest income.
Distribution Partnerships: Circle works with cryptocurrency exchanges like WEEX and others to distribute USDC, sharing a portion of interest revenue with these partners.

This model gives Circle a unique position – providing traditional financial backing stability with blockchain technology efficiency.

Practical Guide: How to Use USDC

For users looking to incorporate USDC into their financial activities:

How to Acquire USDC:

Through Exchanges: Create an account on trusted exchanges like WEEX, Coinbase, or Binance, complete verification, deposit funds, and purchase USDC.
Direct from Circle: Business users can use Circle Account to mint USDC directly by depositing US dollars.
From Other Users: Receive USDC as payment through any compatible wallet.

Using USDC for Key Applications:

Cross-Border Payments: Send money internationally in seconds with minimal fees compared to traditional banking.
Store of Value: Maintain dollar-equivalent value without the volatility typical of other cryptocurrencies.
DeFi Applications: Use USDC in lending protocols, liquidity pools, and yield-generating strategies.
E-Commerce and Payments: An increasing number of merchants now accept USDC for goods and services.

Circle vs. Tether: Understanding the Two Stablecoin Giants

The competition between USDC and USDT represents a fascinating divergence in approaches to digital dollars:

Feature	Circle (USDC)	Tether (USDT)
Reserves Transparency	Monthly attestations by Grant Thornton	Less frequent attestations
Regulatory Approach	Proactive compliance with US regulations	More ambiguous regulatory positioning
Primary Use Cases	Institutional settlements, DeFi, regulated payments	Trading liquidity, gray market transactions
Business Model	"Narrow bank" approach	"Money printer" approach
Profitability	$160M net profit (2024)	$13B+ net profit (vastly higher margins)

Rather than direct competitors, these stablecoins serve different market segments with distinct risk-reward profiles. For users prioritizing regulatory clarity and institutional-grade security, USDC typically represents the preferred option, while USDT often offers broader market penetration and liquidity.

USDC's Technology Infrastructure: Beyond Just a Token

USDC's technical architecture extends far beyond simply being an ERC-20 token:

Multi-Chain Implementation

USDC operates across major blockchain ecosystems including Ethereum, Solana, Algorand, Avalanche, Flow, Tron, Polkadot, and several others.

This multi-chain presence allows USDC to function as a universal settlement layer across diverse blockchain environments.

Cross-Chain Transfer Protocol (CCTP)

Circle's Cross-Chain Transfer Protocol enables USDC to move seamlessly between blockchains without traditional bridging risks. This protocol works by burning USDC on the source chain and minting an equivalent amount on the destination chain, ensuring consistent 1:1 backing.

API and Developer Ecosystem

Circle offers a comprehensive suite of APIs including:

Payments API: For business payment processing
Accounts API: For programmatic USDC management
Marketplaces API: For platform payment facilitation
Mint API: For automated USDC issuance and redemption

These tools have enabled thousands of businesses to integrate USDC functionality directly into their applications.

Regulatory Landscape and Institutional Adoption

Circle's approach to regulation represents a significant competitive advantage:

Regulatory Framework

USDC operates within a clear regulatory framework:

Registered as a money service business with FinCEN
Holds appropriate state money transmitter licenses
Complies with AML/KYC requirements

The passage of stablecoin legislation in the US and Hong Kong has further validated Circle's compliance-first approach.

Institutional Partnerships

Circle's institutional relationships include:

BlackRock: Partnership for USDC Treasury reserve management
Visa: Integration for payment settlement
Mastercard: Strategic collaboration on stablecoin payments
Various Financial Institutions: Growing list of traditional finance partnerships

These relationships provide important credibility and distribution advantages.

USDC in DeFi: The Backbone of Decentralized Finance

USDC has emerged as the preferred stablecoin for many DeFi applications:

Key DeFi Use Cases:

Lending Markets: USDC is extensively used in lending protocols like Aave and Compound.
Decentralized Exchanges: Provides critical liquidity in trading pairs across platforms like Uniswap and Curve.
Yield Strategies: Forms the basis for various yield-generating strategies.
Collateral: Serves as trusted collateral for synthetic assets and over-collateralized loans.

According to DeFiLlama data, USDC consistently ranks among the top assets by total value locked in DeFi protocols.

Real-World Asset Tokenization with USDC

One of the most promising applications for USDC is in real-world asset (RWA) tokenization:

Current RWA Applications:

Tokenized Treasury Bills: Through Circle's partnership with BlackRock
Real Estate Tokenization: Property ownership fractionally represented on-chain
Private Credit Markets: On-chain structured finance products
Trade Finance: Supply chain financing and international trade settlements

Industry experts from Boston Consulting Group predict the RWA market could exceed $16 trillion by 2030, with stablecoins like USDC playing a pivotal role.

Circle's IPO and Future Growth Trajectory

Circle's historic IPO marked a watershed moment for the stablecoin industry:

IPO Performance:

Initial offering price: $31 per share
First week closing price: Over $111 per share
Market capitalization: Exceeding $21 billion

Strategic Challenges:

Despite its success, Circle faces several structural challenges:

Interest Rate Sensitivity: With 99% of revenue derived from reserve interest, Circle's profitability is vulnerable to interest rate fluctuations.
Distribution Dependency: Circle shares significant revenue with distribution partners, particularly Coinbase, limiting profit margins.
Increasing Competition: Traditional financial institutions are developing competing stablecoin solutions.

Growth Opportunities:

To drive sustainable growth, Circle is expanding beyond interest income through:

Payment Infrastructure: Expanding its payment API ecosystem.
Enterprise Solutions: Developing treasury management tools for businesses.
Global Expansion: Targeting high-friction payment corridors in emerging markets.
RWA Integration: Deepening partnerships in the real-world asset tokenization space.

Editor's Note: Citrini7's cyberpunk-themed AI doomsday prophecy has sparked widespread discussion across the internet. However, this article presents a more pragmatic counter perspective. If Citrini envisions a digital tsunami instantly engulfing civilization, this author sees the resilient resistance of the human bureaucratic system, the profoundly flawed existing software ecosystem, and the long-overlooked cornerstone of heavy industry. This is a frontal clash between Silicon Valley fantasy and the iron law of reality, reminding us that the singularity may come, but it will never happen overnight.

The following is the original content:

Renowned market commentator Citrini7 recently published a captivating and widely circulated AI doomsday novel. While he acknowledges that the probability of some scenes occurring is extremely low, as someone who has witnessed multiple economic collapse prophecies, I want to challenge his views and present a more deterministic and optimistic future.

Never Underestimate "Institutional Inertia"

In 2007, people thought that against the backdrop of "peak oil," the United States' geopolitical status had come to an end; in 2008, they believed the dollar system was on the brink of collapse; in 2014, everyone thought AMD and NVIDIA were done for. Then ChatGPT emerged, and people thought Google was toast... Yet every time, existing institutions with deep-rooted inertia have proven to be far more resilient than onlookers imagined.

When Citrini talks about the fear of institutional turnover and rapid workforce displacement, he writes, "Even in fields we think rely on interpersonal relationships, cracks are showing. Take the real estate industry, where buyers have tolerated 5%-6% commissions for decades due to the information asymmetry between brokers and consumers..."

Seeing this, I couldn't help but chuckle. People have been proclaiming the "death of real estate agents" for 20 years now! This hardly requires any superintelligence; with Zillow, Redfin, or Opendoor, it's enough. But this example precisely proves the opposite of Citrini's view: although this workforce has long been deemed obsolete in the eyes of most, due to market inertia and regulatory capture, real estate agents' vitality is more tenacious than anyone's expectations a decade ago.

A few months ago, I just bought a house. The transaction process mandated that we hire a real estate agent, with lofty justifications. My buyer's agent made about $50,000 in this transaction, while his actual work — filling out forms and coordinating between multiple parties — amounted to no more than 10 hours, something I could have easily handled myself. The market will eventually move towards efficiency, providing fair pricing for labor, but this will be a long process.

I deeply understand the ways of inertia and change management: I once founded and sold a company whose core business was driving insurance brokerages from "manual service" to "software-driven." The iron rule I learned is: human societies in the real world are extremely complex, and things always take longer than you imagine — even when you account for this rule. This doesn't mean that the world won't undergo drastic changes, but rather that change will be more gradual, allowing us time to respond and adapt.

The Software Industry Has "Infinite Demand" for Labor

Recently, the software sector has seen a downturn as investors worry about the lack of moats in the backend systems of companies like Monday, Salesforce, Asana, making them easily replicable. Citrini and others believe that AI programming heralds the end of SaaS companies: one, products become homogenized, with zero profits, and two, jobs disappear.

But everyone overlooks one thing: the current state of these software products is simply terrible.

I'm qualified to say this because I've spent hundreds of thousands of dollars on Salesforce and Monday. Indeed, AI can enable competitors to replicate these products, but more importantly, AI can enable competitors to build better products. Stock price declines are not surprising: an industry relying on long-term lock-ins, lacking competitiveness, and filled with low-quality legacy incumbents is finally facing competition again.

From a broader perspective, almost all existing software is garbage, which is an undeniable fact. Every tool I've paid for is riddled with bugs; some software is so bad that I can't even pay for it (I've been unable to use Citibank's online transfer for the past three years); most web apps can't even get mobile and desktop responsiveness right; not a single product can fully deliver what you want. Silicon Valley darlings like Stripe and Linear only garner massive followings because they are not as disgustingly unusable as their competitors. If you ask a seasoned engineer, "Show me a truly perfect piece of software," all you'll get is prolonged silence and blank stares.

Here lies a profound truth: even as we approach a "software singularity," the human demand for software labor is nearly infinite. It's well known that the final few percentage points of perfection often require the most work. By this standard, almost every software product has at least a 100x improvement in complexity and features before reaching demand saturation.

I believe that most commentators who claim that the software industry is on the brink of extinction lack an intuitive understanding of software development. The software industry has been around for 50 years, and despite tremendous progress, it is always in a state of "not enough." As a programmer in 2020, my productivity matches that of hundreds of people in 1970, which is incredibly impressive leverage. However, there is still significant room for improvement. People underestimate the "Jevons Paradox": Efficiency improvements often lead to explosive growth in overall demand.

This does not mean that software engineering is an invincible job, but the industry's ability to absorb labor and its inertia far exceed imagination. The saturation process will be very slow, giving us enough time to adapt.

Redemption of "Reindustrialization"

Of course, labor reallocation is inevitable, such as in the driving sector. As Citrini pointed out, many white-collar jobs will experience disruptions. For positions like real estate brokers that have long lost tangible value and rely solely on momentum for income, AI may be the final straw.

But our lifesaver lies in the fact that the United States has almost infinite potential and demand for reindustrialization. You may have heard of "reshoring," but it goes far beyond that. We have essentially lost the ability to manufacture the core building blocks of modern life: batteries, motors, small-scale semiconductors—the entire electricity supply chain is almost entirely dependent on overseas sources. What if there is a military conflict? What's even worse, did you know that China produces 90% of the world's synthetic ammonia? Once the supply is cut off, we can't even produce fertilizer and will face famine.

As long as you look to the physical world, you will find endless job opportunities that will benefit the country, create employment, and build essential infrastructure, all of which can receive bipartisan political support.

We have seen the economic and political winds shifting in this direction—discussions on reshoring, deep tech, and "American vitality." My prediction is that when AI impacts the white-collar sector, the path of least political resistance will be to fund large-scale reindustrialization, absorbing labor through a "giant employment project." Fortunately, the physical world does not have a "singularity"; it is constrained by friction.

We will rebuild bridges and roads. People will find that seeing tangible labor results is more fulfilling than spinning in the digital abstract world. The Salesforce senior product manager who lost a $180,000 salary may find a new job at the "California Seawater Desalination Plant" to end the 25-year drought. These facilities not only need to be built but also pursued with excellence and require long-term maintenance. As long as we are willing, the "Jevons Paradox" also applies to the physical world.

Towards Abundance

The goal of large-scale industrial engineering is abundance. The United States will once again achieve self-sufficiency, enabling large-scale, low-cost production. Moving beyond material scarcity is crucial: in the long run, if we do indeed lose a significant portion of white-collar jobs to AI, we must be able to maintain a high quality of life for the public. And as AI drives profit margins to zero, consumer goods will become extremely affordable, automatically fulfilling this objective.

My view is that different sectors of the economy will "take off" at different speeds, and the transformation in almost all areas will be slower than Citrini anticipates. To be clear, I am extremely bullish on AI and foresee a day when my own labor will be obsolete. But this will take time, and time gives us the opportunity to devise sound strategies.

At this point, preventing the kind of market collapse Citrini imagines is actually not difficult. The U.S. government's performance during the pandemic has demonstrated its proactive and decisive crisis response. If necessary, massive stimulus policies will quickly intervene. Although I am somewhat displeased by its inefficiency, that is not the focus. The focus is on safeguarding material prosperity in people's lives—a universal well-being that gives legitimacy to a nation and upholds the social contract, rather than stubbornly adhering to past accounting metrics or economic dogma.

If we can maintain sharpness and responsiveness in this slow but sure technological transformation, we will eventually emerge unscathed.
