What Is USDC and How It Works: A Guide for Companies

What is USDC is the first question a CFO should settle before moving a single company dollar over a stablecoin rail. The short answer: USDC is a digital dollar that circulates on blockchain networks, issued by a regulated company and backed 1:1 by liquid reserves attested every month. The long answer, the one that matters for treasury, collections and payments, is what this guide covers.

At Soulbit Academy we explain these topics with verifiable data and without inflated promises. Here you will see who issues USDC, what exactly sits behind each token, how a transaction travels, what real companies use it for and which risks deserve scrutiny. We also cover the 2025 and 2026 regulatory shift that turned payment stablecoins into a supervised category on both sides of the Atlantic.

USDC in plain terms: a digital dollar on blockchain

USDC, short for USD Coin, is a payment stablecoin. Each token represents one US dollar and can be redeemed for one dollar from its issuer. Unlike a bank deposit, USDC lives on public blockchain networks. That gives it two properties no bank dollar has: it moves in minutes to any part of the world and it operates 24 hours a day, 7 days a week.

The scale is no longer experimental. According to Circle, as of August 3, 2026 there were $72 billion of USDC in circulation, and the token is natively issued on 35 blockchain networks. For a company, that means deep liquidity and several networks to choose from based on cost and speed.

How does a company get USDC in the first place? Either by collecting it from a client that pays in USDC, or by converting fiat through a licensed platform. Large institutions mint directly with the issuer, while most businesses buy and redeem through regulated intermediaries that handle the conversion. The price tracks 1 dollar per token, plus the platform's spread or fee.

How is USDC different from a cryptocurrency like bitcoin?

In its backing and its purpose. Bitcoin is a volatile asset with no issuer: the market alone sets its price. USDC uses the same distributed ledger technology, but its value is anchored to the dollar because liquid reserves stand behind every token and an issuer is obligated to redeem it at par. We unpack this distinction in stablecoin vs cryptocurrency.

Who issues USDC and how the 1:1 reserve works

USDC is issued by Circle, a US financial infrastructure company founded in 2013. The mechanism is simple to describe. When an institutional client delivers dollars to Circle, Circle mints the same amount of USDC. When that client redeems, Circle burns the tokens and returns the dollars. Circulation rises and falls with real demand.

What backs each USDC?

Cash and cash-equivalent reserves, segregated from Circle's corporate assets. According to Circle's transparency page, most of the reserve is held in the Circle Reserve Fund, an SEC-registered government money market fund. That fund holds short-dated US Treasury bills, overnight Treasury repurchase agreements and cash. The remainder sits as deposits at regulated banks.

Verification does not rest on the issuer's word. A Big Four accounting firm publishes a monthly attestation, under AICPA standards, confirming that the value of the reserves equals or exceeds the USDC in circulation. Any company can download those reports and review them before operating. That monthly disclosure discipline is now also a legal requirement in the United States, as we will see in the regulatory section.

How a USDC transaction travels

A USDC transaction is an entry on the ledger of a blockchain network. The paying company signs an order from its account, the network validates it and the balance changes hands. There are no correspondent banks, no cut-off times and no distinction between a domestic and an international payment. Settlement typically confirms in seconds or minutes depending on the chosen network.

The cost side is worth noting. Sending USDC carries a network fee that varies by blockchain and congestion, usually cents on modern networks. There is no percentage taken along the way and no intermediary deducting charges in transit. For a treasury team, that makes the total cost of a payment predictable before it is sent, something the correspondent model rarely offers.

Every movement is recorded with a unique, public, verifiable identifier. For the accounting team, that turns reconciliation into a direct match between invoice and transaction, a method we explain in reconcile stablecoin payments in your accounting. The trade-off is that a confirmed payment is irreversible: verifying the recipient before sending is a mandatory discipline.

Feature	Dollar in a bank account	USDC
Where the balance lives	The bank's internal ledger	Public blockchain network
Operating hours	Banking business windows	24 hours, 7 days
International payment	Correspondent chain, 1 to 5 days	Direct settlement in minutes
Value backing	Bank balance sheet and deposit insurance	1:1 reserves in cash and Treasury debt
Traceability	Bank statements	On-chain record anyone can verify
Reversibility	Recall and bank mediation possible	Irreversible once confirmed

Business use cases: collections, payments and treasury

For a Latin American SMB with international operations, USDC solves three concrete problems.

The first is collections. A company exporting services or goods can accept USDC from clients in any country, with settlement in minutes and no waiting for the corridor's banking window. The second is outbound payments: international suppliers and contractors receive digital dollars the same day, a flow we detail in pay international contractors in USDC.

The third is dollar treasury. A company that invoices in local currency but buys in dollars can hold part of its cash in USDC as operational cover, without opening accounts abroad. The contrast with the traditional banking rail, in time and cost, is developed in SWIFT vs stablecoin for international payments.

An example grounds the idea. A software agency in Bogota invoices $40,000 a month to clients in the United States and Europe. It collects in USDC through payment links, pays its contractors in other countries from that same balance and converts to local currency only what domestic expenses require. The digital dollar works as an operating layer between both worlds.

These three fronts share one condition: the company needs a rail with compliance controls, not a personal wallet. B2B payments demand counterparty verification, funds monitoring and an auditable record.

Risks a CFO should weigh before operating

No treasury decision is complete without the risk column. With USDC there are three worth understanding well.

The first is issuer risk. USDC's peg depends on Circle holding sufficient, liquid reserves. Monthly attestations and reserve segregation mitigate this risk, but they do not eliminate it: the token is a liability of the issuer, not a government-guaranteed deposit.

Can USDC lose its peg to the dollar?

It has happened, and the case is instructive. In March 2023, the failure of a US bank where Circle held part of the reserve's cash pushed USDC below 1 dollar over a weekend. Once authorities guaranteed the deposits, the token recovered its peg within hours. The lesson for a company: the quality and diversification of the reserves matter more than the token's brand.

The third risk is regulatory and operational. Stablecoin rules are still being implemented in many countries, and the accounting and tax treatment varies by jurisdiction. Operationally, irreversibility demands internal controls: tiered approvals, address verification and monitoring of every transaction.

Risk	What it means	How it is managed
Issuer	The peg depends on Circle's reserves	Review the monthly attestations and reserve composition
Market depeg	Price can drift from 1 dollar under stress	Size the exposure and understand the redemption mechanism
Regulatory	Rules still rolling out by country	Confirm the local framework with legal and tax advisors
Operational	A confirmed payment is irreversible	Tiered approvals and recipient verification
Compliance	Funds must have a lawful origin and destination	Operate through platforms with KYB and AML/KYT monitoring

The regulatory framework: the GENIUS Act and MiCA

The year 2025 changed the legal status of payment stablecoins. In the United States, the GENIUS Act, signed on July 18, 2025, created the first federal framework for payment stablecoin issuers. It requires 100% backing in liquid assets, such as dollars and short-term Treasury debt, monthly public disclosure of reserve composition and a license to issue.

In the European Union, the MiCA regulation classifies currency-referenced stablecoins as e-money tokens, with par redemption and prudential supervision. Circle obtained an electronic money institution license in France in July 2024 and became the first global stablecoin issuer to comply with MiCA.

In Latin America the picture advances country by country. Some jurisdictions already have fintech or virtual asset service provider frameworks, while others are still drafting rules. For a regional company, the two frameworks above are the practical reference, because they set the standard local regulators watch when designing their own.

For a CFO, the practical reading is this: a reserve-backed payment stablecoin is no longer an experiment without rules, but a regulated category in the two largest Western economies. Improving cross-border payments is also a global public priority, as reflected in the BIS cross-border payments programme. None of this replaces the analysis of each country's local framework, which remains the job of the company and its advisors.

How a company operates USDC in practice: the Soulbit case

The theory above lands on a B2B platform. Soulbit is a stablecoin payment and treasury rail for companies, and its V1 defines an honest scope worth knowing before deciding.

The company first completes KYB verification, which validates the legal entity and its beneficial owners. With the account active, it holds balances in USDC and USDT, plus fiat limited to USD, EUR and GBP. It can collect with payment links and QR codes, pay individually or in batches, schedule recurring payroll runs and request a quote to convert between crypto and fiat. Digital asset custody is institutional, and every transaction goes through on-chain AML/KYT monitoring. The only local banking rail available today is Colombia, with disbursement in Colombian pesos and dollars.

Just as important is what V1 does not offer: no cards, no yield on balances, no proprietary token, no native mobile app, and EURC support sits on the roadmap, not in production. That perimeter protects companies from inflated expectations. For a full view of the platform, read what is Soulbit and how it works.

For a LATAM finance team, the practical division of labor is clear. Local banking stays in charge of local currency, taxes and payroll at home. The stablecoin rail takes over the dollar layer: collecting from foreign clients, paying foreign suppliers and holding hard currency reserves with full traceability.

The final balance is straightforward. USDC is today the most transparent way for a company to operate digital dollars: an identified issuer, reserves attested every month and a legal framework consolidating fast. The CFO's job is not to believe in the technology, but to assess it with the same criteria applied to any financial counterparty.
