A stablecoin is a company’s IOU on a blockchain
Tether holds dollars and US Treasuries and, in return, issues USDT tokens with a promise to redeem each for a dollar. The token lives on a blockchain, so it moves between people without a bank, around the clock and across borders. But the promise comes from a company, not a state: there is no deposit insurance, and the issuer’s contract has a “freeze address” button. Four stablecoins you will meet are below; the difference is who issues them and who can take them away.
One USDT — nine networks. Choosing a network is choosing the fee and who stands behind the token
USDT on Tron and USDT on Ethereum are different tokens — do not mix them up when sending. On five networks Tether itself issues it; on the others — bridges and exchanges under their own name. The contract address is the only way to tell real USDT from a fake with the same ticker.
Who pays the fee, and in what
An exchange fee is not a network fee
The network must match on both sides

How to cash out USDT and buy again — simple rules
Money on an exchange is lost more often to a “too good” rate, someone else’s transfers hitting your card, and an unknown seller than to hackers. Eight simple rules.
Look at the ordinary market rate
Safer: you pay with your own money and receive USDT
Riskier: you sell USDT and someone else’s money hits your card

What to know before moving everything into USDT
USDT is more convenient than a bank, but it is not a bank and not cash: it has an owner, and the owner has a button. Six facts with dates and sources.
The issuer can freeze your address — and does
The USDT contract has addBlackList and destroyBlackFunds: a blacklisted address cannot send, and the balance can be zeroed. Tether reports more than $4.4B of frozen USDT and works with 340+ agencies in 65 countries; BlockSec counted $5.7B across 9,600 addresses as of July 2026. Circle’s function is called blacklist and is used on a court order or police request.
The state reaches you, not the blockchain
On 6 March 2025 Tether froze about $27M on Garantex exchange wallets at the request of the US and Europe — the exchange stopped the same day. A freeze does not ask whose money it is: every client of that address is hit. For you that means: the larger and more “known” the intermediary, the more visible it is to agencies.
Two real ways to lose USDT
First — a lost key: phrase in one place, phone drowned, card thrown out. Second — an exchange lock: once a year an exchange may ask you to prove the origin of funds, and while you hunt for papers the money sits. Hackers and a “USDT collapse” sit at the bottom of the list. Takeaway: key in two places, large amounts in your own wallet, not on an exchange.
European Union: MiCA and DAC8
Under MiCA, EU exchanges delisted USDT by 31.03.2025 — USDC and EURC remain. Under the DAC8 directive, from 1 January 2026 every exchange operating in the EU sends tax authorities once a year the data of all its users and their transaction totals — no minimum threshold; first filing due by 30.09.2027. If you have an account on a European exchange, your EU country’s tax office gets the whole file.
Russia: Federal Law 282-FZ from 1 September 2026
Crypto is recognized as property; paying with it inside the country is banned. Inside Russia, USDT deals go only through licensed intermediaries: exchanges, brokers, OTC desks (mandatory from 1 July 2027). Sending to foreign exchanges is not banned. For non-qualified investors the central bank is preparing a ₽300,000/year limit after a test; USDT is on the list allowed for trading. This is a fresh law — check details with a lawyer.
This is not a grail: the peg and the reserves
USDT fell to $0.95 (12.05.2022, $7B withdrawn in two days), USDC — to $0.87 (11.03.2023, $3.3B of reserves stuck in a failed bank). Tether’s first full audit came only in August 2026 — KPMG for 2025, and the report itself is unpublished; for twelve years before that there were only attestations, and in 2021 the New York Attorney General wrote that full-backing claims “were a lie,” with fines of $18.5M and $41M. Reserves are mostly US Treasuries, about $141B.
Buying direct from the issuer is possible — but rarely worth it
Issuers sell and redeem tokens only in bulk and after identity checks; under about a hundred thousand dollars the only road is exchanges, P2P, and OTC desks. Terms — from the issuers’ sites as of 25.09.2026.

What people ask about USDT
How is USDT different from USDC?
By the issuer and who watches them. USDT is issued by Tether in El Salvador; the first full audit came only in 2026, but it is everywhere and roughly twice as large. USDC is issued by Circle in the US under regulator oversight, with Deloitte audits and an EU authorization. Both can freeze an address.
Which network is cheapest for USDT transfers?
Solana, BSC, and Polygon — fractions of a cent; TON — about two cents. Tron without rented energy — $2–4; Ethereum — from about a dollar to ten at peak hours. But you pick the network by where you are expected: OTC desks and exchanges most often ask for Tron.
Are Binance-Peg USDT and USDT0 real USDT?
They are tokens backed by real USDT on another network: Binance-Peg sits on Binance’s books; USDT0 sits in an Ethereum contract under a Tether license. They move like USDT, but you cannot redeem them with Tether directly, and Tether is not the party on the hook. For everyday transfers the difference is small; for large holdings it matters.
Does USDT pay interest?
Tether itself — no, and since 2025 the US GENIUS Act bars issuers from paying interest just for holding. You can still deposit USDT into protocols like Aave, Venus, and EVAA — a floating rate, usually about 4–6% APY; in Mitilena Wallet that is done without handing over your key. Exchange “USDT staking” is a loan to the exchange on its word.
What happens to USDT if Tether shuts down?
The tokens stay on-chain, but nobody will redeem them one-for-one for dollars — the price will track whatever is left in the reserves. That is why you should not keep all savings in one stablecoin from one company.
I sent USDT on the wrong network. What now?
If it is the same address family (Ethereum → BSC on the same 0x address) and you hold the key — add the network in the wallet; the coins are there. If you tried a Tron address in Ethereum format or the reverse — the wallet will not let that through. If you withdrew to an exchange on the wrong network — contact exchange support; sometimes they recover it for a fee.
