What Is USDT (Tether)?

What is USDT in practical terms? It is a token that tries to be worth exactly one US dollar, issued by a company called Tether and used heavily on crypto exchanges as a stand-in for dollars. Traders price coins in it, move funds between platforms with it and park money in it between trades. Understanding what holds its value at one dollar, and what could break that, matters to anyone who keeps a balance in it.

How USDT is created and removed

Tether issues new USDT when approved customers, typically large trading firms, send it dollars or equivalent assets. It destroys ("burns") USDT when those customers redeem tokens for dollars. Ordinary users rarely deal with Tether directly; they buy and sell USDT on exchanges or from other users.

This mint-and-redeem loop is what keeps the price near $1. If USDT trades at $0.995 on the market, large holders with redemption access can buy it cheaply and redeem it at $1, pushing the price back up. If it trades above $1, they can mint new tokens and sell them. The mechanism works only as long as redemptions are reliably honoured.

What backs it

Tether states that its tokens are backed by reserves, mostly short-term US government debt and cash equivalents, along with other assets. It publishes periodic reports prepared by an accounting firm. These attestations describe holdings at a point in time; they are not the same as a full audit, and they do not give token holders the legal protections of a bank deposit.

That is the core risk. USDT's value rests on the quality of the reserves, the company's willingness and ability to redeem, and the legal treatment of token holders if something went wrong. In periods of stress, dollar stablecoins have briefly traded below $1, and some smaller stablecoins have lost their peg entirely.

An illustrative de-peg

If you hold 10,000 USDT and the market price drops to $0.997, your holding is worth 10,000 × 0.997 = $9,970, a paper loss of $30. That is small, but it shows that the "stable" in stablecoin is a target, not a guarantee.

Networks: same token, different chains

USDT is issued on several blockchains. The token has the same name everywhere, but each version lives on its own chain and cannot move to another chain by an ordinary transfer.

The rule to remember: the sender and receiver must use the same network. If an exchange's deposit page asks for TRC20 and you withdraw on ERC20, the funds may be lost or require a manual recovery the exchange is not obliged to attempt. Addresses that both start with 0x on different chains make the mistake easy.

Fees depend on the network. When withdrawing from an exchange you usually pay a flat withdrawal fee in USDT that differs by network; sending from your own wallet, you pay in the chain's native coin, so you need a small balance of it.

What people use USDT for

• Trading pairs: many exchanges quote coins against USDT rather than dollars.
• Moving between platforms: transfers can settle in minutes, at any hour.
• Holding dollar value: people in countries with unstable currencies sometimes keep savings in dollar stablecoins, accepting issuer risk in exchange for access to dollars.
• Payments: some merchants and freelancers accept USDT.

Each use carries the same underlying exposure to the issuer, plus the operational risks of blockchain transfers. See how crypto works for the transfer mechanics.

USDT compared with a bank balance

For a trader, the practical difference is finality and timing: a USDT transfer arrives in minutes at any hour, but if it goes to the wrong place there is no bank to call.

Regulation

Stablecoin regulation is developing quickly. The EU's Markets in Crypto-Assets Regulation sets requirements for issuers of stablecoins offered in the EU, and several exchanges have restricted non-compliant stablecoins there. Other jurisdictions are writing their own regimes. Availability of USDT on a given platform can therefore depend on where you live, and rules may change after you buy.

How USDT shows up on exchanges

On many crypto exchanges the main trading pairs are quoted in USDT rather than dollars: BTC/USDT, ETH/USDT and so on. That means the price you see is a price in tokens, and turning a profit into spendable money involves one more step, selling USDT for your local currency, with its own spread and fee.

It also means a USDT-quoted price and a USD-quoted price for the same coin can differ slightly whenever USDT itself is not exactly at $1. Traders who compare prices across platforms need to know which unit each one uses. For most day-to-day purposes the difference is small, but in stress it can widen.

Some exchanges also offer "earn" products on USDT balances. Any interest paid there comes from the platform's lending or other activities, not from Tether, and it adds the platform's own risk on top of the issuer's. How crypto works explains where such yields come from.

Safer handling in practice

1. Buy only on platforms authorised in your country, and check the ten provider checks.
2. Copy the deposit address and network from the receiving platform, and send a small test amount first.
3. Check the first and last several characters of the pasted address; clipboard malware and "address poisoning" swap in lookalikes.
4. Be wary of anyone offering to sell USDT for cash at a premium or asking you to "verify" a wallet by approving a transaction.
