# 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.

## Comparison

| Criterion | USDC | USDT |
| --- | --- | --- |
| **Issuer**: Who 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 composition**: What 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 cadence**: How 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 posture**: Which 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 corridors**: Where 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 fits**: The 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](https://infinite.net/accounts/rails).

### 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](https://infinite.net/resources/learn/glossary/reserve-attestation.md) 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](https://infinite.net/resources/learn/insights/genius-act-stablecoin-payments.md) 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.
