USDT vs USDC: How the Two Dollar Stablecoins Differ for Card Spending
USDT vs USDC: both aim to track the US dollar, but issuer, reserve reporting, EU register status and supported networks differ. What it means for spending.
USDT and USDC are both stablecoins meant to track the US dollar, so for a single card payment they play the same role. The differences sit behind the token: who issues it, what each issuer says backs it and how often it reports on that, where it appears on regulators’ lists, and which blockchains carry it. Tether issues USDT and Circle issues USDC, and each describes its own product in different terms.
This guide sets out those differences using regulators’ documents and each issuer’s own statements about its own token.
What Both Tokens Are
Visa defines stablecoins as digital currencies on blockchain networks that aim for a stable value by being tied to a reserve asset, such as a regular currency. FINRA (Financial Industry Regulatory Authority) describes them as crypto assets that try to keep a steady value against a reference asset, and splits them into those said to be backed by reserves and those that use an algorithm.
Both USDT and USDC fall into the reserve-backed group, according to their issuers. Tether says each USD₮ is pegged one-to-one with the US dollar and backed by its reserves. Circle says USDC can be redeemed one-to-one for US dollars.
FINRA adds a warning that applies to any stablecoin. It says stablecoins can drift away from their reference price, such as $1, can face cybersecurity risks, and have in some cases collapsed. A stablecoin is designed to hold its value, but that design is not a guarantee.
Who Issues Each Token
USDC. Circle says USDC is issued by regulated affiliates of Circle. Its page states that Circle Internet Financial, LLC is licensed by the New York State Department of Financial Services (NYDFS) as a money transmitter and for virtual currency business activity, and that another affiliate is licensed by the Bermuda Monetary Authority.
USDT. Tether says it launched in 2014 as a platform for using regular currencies on blockchains. The copyright line on its site names Tether Operations, S.A. de C.V. Tether also issues tokens linked to the Mexican peso and to gold, but USD₮ is the dollar version.
How Each Issuer Describes Its Reserves
The two issuers describe what stands behind their tokens differently, as of October 2026.
Circle says USDC is fully backed by highly liquid cash and cash-equivalent assets, with holdings equal to or above the amount in circulation. It says most of the reserve sits in the Circle Reserve Fund, which it describes as an SEC-registered government money market fund, and that a Big Four accounting firm provides monthly reserve attestations.
Tether says every token is fully backed by its reserves, and that those reserves include traditional currency, cash equivalents and other assets, among them receivables from loans Tether has made to third parties. Tether says it typically publishes daily figures on tokens in circulation and quarterly information on its reserves.
For a sense of what a regulator expects, NYDFS issued guidance in June 2022 for US dollar stablecoins issued under its supervision. It says such a token must be fully backed by a reserve at the end of each business day, holders must be able to redeem at par within a set time, reserve assets must be kept apart from the issuer’s own assets, and the reserve must be examined by an independent accountant at least monthly. The guidance applies only to stablecoins issued by firms under NYDFS supervision, and it does not name either USDT or USDC. It is a useful checklist when you read any issuer’s claims.
Redeeming for Dollars
- Circle says its Mint service lets exchanges, banks and large institutions redeem USDC one-to-one for dollars, and that Mint is not open to individuals or small businesses.
- Tether’s fees page lists a minimum redemption of 100,000 USD, a redemption fee of the greater of $1,000 or 0.1%, and a non-refundable verification fee of 150 USD₮, as of October 2026.
Circle points individuals to exchanges, neobanks and digital wallets, and Tether’s 100,000 USD minimum puts direct redemption out of reach for small amounts.
Status on the EU Register
In the European Union, the Markets in Crypto-Assets Regulation (MiCA) sets rules for issuers of crypto-assets, including e-money tokens, covering disclosure, authorisation and supervision. ESMA publishes an interim MiCA register as a set of files, including one for e-money token issuers.
The version of that file we checked in October 2026 lists Circle Internet Financial Europe SAS, authorised by the French supervisor ACPR as an electronic money institution, with a white paper for USDC. The same file did not list a Tether entity. ESMA notes that it refreshes the register weekly, so information held by national authorities may take time to appear. If you live in the EU, check whether your card provider supports a given token where you are.
Supported Networks
Both tokens run on several blockchains, and the network matters when you move them to a card.
- Circle says USDC runs natively on 38 blockchain networks, as of 16 September 2026, including Ethereum, Solana, Base, Linea, Polygon PoS and Stellar.
- Tether says its tokens are built on several blockchains, among them Ethereum, Solana, Tron, Ton and Algorand, and it keeps a full list on its site.
Tether also warns that because its tokens use different transport protocols, you should check the destination address and the protocol before sending. The same care applies to USDC. Send a token on a network your card provider does not support, and the transfer may not arrive where you expect.
Spending Either One With a Card
Visa describes stablecoin-linked cards as a way to connect stablecoin wallets to its network so people can spend at millions of merchants.
NORA CARD, a prepaid Mastercard, lists both USDT and USDC among 14 top-up assets, as of October 2026, and converts each top-up into a USD balance, according to the official site as summarised on our NORA CARD page. NORA CARD lists one 1.75% top-up fee with no separate rate by coin, and a $10 minimum, as of October 2026. Our guides on how to spend USDT and topping up a crypto card with USDT walk through the steps.
