Tether (USDT)

What Tether is

Tether, ticker USDT, is a stablecoin designed to hold a value of one US dollar. It is issued by a company rather than mined or minted by a protocol, and its transparency page identifies the issuer as Tether Operations, S.A. de C.V. Tether states that "all Tether tokens are pegged at 1-to-1 with a matching fiat currency and are backed 100% by Tether's Reserves," and that "the Tether Issuer's assets exceed its liabilities" (source: Tether transparency page, September 2026). As of September 2026 Tether's own site shows a USD₮ market capitalization of $183.38 billion.

USDT exists mainly as a way to hold and move dollars on blockchain rails. It is the unit most exchanges quote pairs against, which is why it turns up in almost every trading workflow whether or not anyone set out to buy it.

How it works

USDT is a token rather than a native coin. It does not have its own chain. The same dollar claim is issued as a token contract on several different blockchains, and Tether describes itself as "a digital token built on multiple blockchains" (source: Tether transparency page). TRON's developer documentation, for instance, states that the network "hosts the largest stablecoin network in crypto (TRC-20 USDT)."

This matters more than it sounds. USDT on one chain is not automatically spendable on another. If you withdraw USDT from an exchange, you choose a network, and sending to an address on the wrong network is one of the most common ways people lose funds permanently. Withdrawal fees also differ sharply between chains, because you are paying that chain's network fee, not Tether's.

The peg is maintained by issuance and redemption at the issuer rather than by an algorithm. When authorized parties deposit dollars, new tokens are created; when they redeem, tokens are destroyed. Tether says information on circulating tokens "is typically published daily" on its transparency page. Between those primary-market flows, the price on exchanges is set by ordinary supply and demand, which is why USDT can trade slightly above or below a dollar on a given venue at a given moment.

Direct redemption with the issuer is not the same as selling USDT on an exchange. Anyone planning to redeem at source should read Tether's current terms of service for eligibility, minimum sizes, verification requirements, and fees, since those terms are set by the issuer and change.

Supply and tokenomics

USDT has no fixed supply and no issuance schedule. The number of tokens outstanding is whatever has been issued against reserves and not yet redeemed, so circulating supply grows and shrinks with demand rather than following a curve.

The relevant question for a fiat-backed stablecoin is not scarcity but what stands behind each token. Tether publishes quarterly attestation figures.

The reserve buffer is the figure to watch over time. It is the margin by which the issuer says its assets exceed the tokens it owes, and it is what absorbs losses on reserve assets before token holders are affected.

Tether also issues other tokens, including Tether Gold (XAU₮). In a separate August 2026 statement, the company reported that Tether Gold holdings rose 9.5% during Q2 2026 while the gold price fell 14.1% over the same quarter (source: Tether, August 2026). Those are distinct products with distinct backing and should not be confused with USD₮.

History

Tether's transparency page carries a copyright range beginning in 2013, making it one of the oldest continuously issued stablecoins. For most of that history, the central argument about Tether has been the quality and verifiability of its reserves, and the company's disclosure practice has changed substantially over time.

The clearest recent milestone is auditing. On 13 August 2026 Tether announced that KPMG U.S. had issued an unqualified audit opinion on the company's 2025 financial statements, describing it as "the largest inaugural financial audit in history" and noting that an unqualified opinion is "the most positive form of opinion an independent auditor can issue" (source: Tether, August 2026). That is a meaningful change from attestation-only reporting, and it is recent enough that its practical effects are still unfolding.

Tether has also pushed into infrastructure beyond the token itself. In August 2026 the company announced a collaboration with First Data and BKN301 to deploy its Hadron platform as the core technology for tokenizing institutional-grade real estate assets in Saudi Arabia (source: Tether, August 2026).

Risks and what to watch

The first risk with any fiat-backed stablecoin is issuer risk. USDT is a claim on a company. If the reserves behind it are impaired, or if the issuer cannot process redemptions, the token's price is not protected by anything in the code. Tether's own statements are the primary disclosure, and quarterly attestations plus the 2025 financial audit are the documents to read rather than secondhand summaries.

The second is chain risk. Because USDT is deployed as a contract on multiple networks, a failure or halt on one of those chains affects the tokens issued there. So does sending to the wrong network, which no support desk can reverse.

The third is regulatory. Stablecoin rules differ by jurisdiction and have been moving quickly. Some venues have restricted or delisted particular stablecoins for particular regions in response to local requirements, and a delisting can force holders to convert on short notice. RampAtlas tracks availability by jurisdiction because this changes more often than most asset facts.

Finally, watch the reserve buffer and the composition of reserves in each quarterly report. Those two numbers, not the market price, describe the actual condition of the token.

Frequently asked questions

Who issues Tether and who backs it?

Tether's transparency page identifies the issuer as Tether Operations, S.A. de C.V. The company states that tokens are "pegged at 1-to-1 with a matching fiat currency and are backed 100% by Tether's Reserves," and that its assets exceed its liabilities. As of the Q2 2026 report published in July 2026, Tether reported a $4.11 billion reserve buffer against roughly $184.6 billion in USD₮ issuance.

Is Tether audited?

As of August 2026, yes. Tether announced on 13 August 2026 that KPMG U.S. issued an unqualified audit opinion on its 2025 financial statements. Before that, the company's public reporting consisted of periodic attestations rather than a full financial audit.

Which blockchain should you use to send USDT?

Whichever one both the sender and the receiver support. Tether issues USD₮ on multiple blockchains, and tokens on one network cannot be received at an address on another. Check the network the receiving exchange or wallet expects before withdrawing, and compare the network fee on each, since these differ by chain rather than by issuer.

Why does USDT sometimes trade slightly above or below one dollar?

Because the exchange price is set by order book supply and demand, not by the issuer. Creation and redemption happen in the primary market with the issuer; the secondary market price can drift by a fraction of a percent, and by more during periods of stress or thin liquidity.

Where can you buy Tether?

Nearly every centralized exchange quotes markets in USDT, but availability of the token itself depends on your jurisdiction, and some regions restrict specific stablecoins. See where to buy Tether for the venues that serve your country or state, and Exchanges to compare them.
