USDC vs USDT for B2B payments: how do they compare?
USDC and USDT are both dollar-pegged stablecoins that settle B2B payments in minutes, 24/7. They differ at the issuer level: USDC is issued by Circle, a US company publishing monthly examined reserve attestations; USDT by Tether, an offshore issuer attesting quarterly with a broader reserve mix. Neither wins every corridor — liquidity and counterparty policy decide.
Both coins do the same job in a B2B payment: a dollar-pegged token that settles in minutes, around the clock, without waiting on banking hours. The differences sit at the issuer level — who stands behind the token, what backs it, how often the backing is examined, and where liquidity is deepest — so this page compares issuers, not rails. Every cell states what the issuers themselves publish; there are no market figures here.
The comparison lands in the GENIUS Act era: since 2025, US payment stablecoin issuers owe monthly reserve reports — tokens outstanding, plus the amount and composition of reserves — examined by a registered public accounting firm. What that changes for payments teams is covered in What the GENIUS Act changes for stablecoin payments, and how to read an issuer’s report in the reserve attestation glossary entry.
On Infinite (infinite.net), the choice is policy, not plumbing: USDC, USDT, OUSD, and USDG move from the same account that holds your dollars, with conversion and routing behind the API and every counterparty screened before funds move — see stablecoin payments your compliance team will approve.
| Criterion | USDC | USDT |
|---|---|---|
| IssuerWho stands behind the token, and where that company is domiciled. | Issued by Circle, a US-domiciled company — inside the framework the GENIUS Act of 2025 created for US payment stablecoin issuers. | Issued by Tether, a company domiciled outside the United States — regulated where it is incorporated, not as a US payment stablecoin issuer. |
| Reserve compositionWhat backs the token, as disclosed in the issuer’s own published reports. | Reserves reported as cash and short-dated US Treasuries, held one-for-one against tokens in circulation and disclosed monthly. | Published attestations report US Treasuries alongside other asset classes; the attestation discloses the full composition — read it, not the headline. |
| Attestation cadenceHow often an independent accounting firm examines the issuer’s reserve claims. | Monthly attestations examined by a registered public accounting firm — the cadence the GENIUS Act made statutory for US issuers. | Quarterly attestations from an independent accounting firm, with additional reserve figures self-published by the issuer between reports. |
| Regulatory postureWhich disclosure regime the issuer answers to in the GENIUS Act era. | As a US issuer, monthly examined reserve reporting is a statutory obligation, with the CEO and CFO attesting to each report’s accuracy. | An offshore issuer’s access to the US market runs through the Act’s separate treatment of foreign issuers; its disclosures follow its own attestation program. |
| Liquidity and corridorsWhere the token is easiest to source, convert, and settle at size. | Deepest on regulated US venues and in corridors where counterparties and their auditors expect a US-regulated issuer. | Deepest across many emerging-market corridors, where counterparties already hold, invoice, and settle in USDT. |
| Where each fitsThe B2B situations where each coin tends to be the default. | When the compliance file leads: vendor diligence, auditors, and US counterparties tend to clear a US issuer with statutory monthly disclosures fastest. | When the corridor leads: if recipients already hold and price in USDT, paying in it removes a conversion they would otherwise make. |

Frequently asked questions
Which is better for B2B payments: USDC or USDT?
Neither is categorically better — compare reserve composition, attestation cadence, issuer regulation, redemption terms, and liquidity in the corridors you pay, then set the choice per corridor as policy. Infinite’s network settles in fully-reserved, attested stablecoins and supports both coins, so the pick is per transfer, not per integration. The broader question is answered on the stablecoin payments page.
Who issues USDC and USDT?
USDC is issued by Circle, a US-domiciled company; USDT is issued by Tether, which is domiciled outside the United States. Domicile decides the disclosure regime: US payment stablecoin issuers owe monthly, examined reserve reports under the GENIUS Act of 2025, while offshore issuers follow their own published attestation programs.
How do USDC and USDT reserve attestations differ?
Mainly in cadence: Circle publishes monthly attestations examined by a registered public accounting firm — the statutory cadence for US issuers — while Tether publishes quarterly attestations. Both report tokens outstanding and reserve composition; the composition section is the part a treasury team should actually read. The reserve attestation glossary entry covers how.
Does the GENIUS Act apply to USDC and USDT?
Directly to USDC: Circle is a US payment stablecoin issuer, so monthly examined reserve reporting is a statutory obligation. Tether is domiciled offshore, so USDT’s standing in the US market runs through the Act’s separate provisions for foreign issuers. Our essay on what the GENIUS Act changes for stablecoin payments covers the requirements in full.
Do businesses have to choose between USDC and USDT?
No. On Infinite, USDC and USDT are assets on the same payments API — the same account that holds your dollars sends either coin, with every counterparty screened before funds move and conversion and routing handled behind the API. Most treasury teams set a per-corridor policy rather than standardizing on one coin.
