How to pay with USDT when you have never done it

When a seller writes "USDT only" or a checkout offers "pay with USDT", they are asking for one thing: send a set number of USDT to an address they give you, on a network they name. USDT is a digital dollar, so a 50-dollar bill is paid with 50 USDT.

To get from there to "paid", three things have to match: the amount, the network and the address. You also need USDT of your own, in an exchange account or in a wallet app. Get all three right and the money arrives. Get one wrong and there is no bank to call.

Below is the whole route: where to get USDT, what TRC20 means, how to pay a person and how to pay at an online checkout, and how to prove the payment landed.

What does USDT payment mean?

USDT is a stablecoin: a token issued by the company Tether and kept equal to one US dollar. It is not a card payment or a bank transfer. It moves between addresses on a blockchain, a public ledger that nobody can edit after the fact.

Sellers like it for exactly that reason. A USDT payment cannot be charged back, it reaches them from any country within minutes, and nobody holds it for three banking days. If you want the longer story, here is what USDT is and why so many sellers ask for it.

For you as the buyer, the consequence is short: a USDT payment is final the moment it is sent. That is why most of this guide is about checking things before you press the button.

Where do I get USDT to pay with?

Most people buy USDT on a crypto exchange. You open an account, pass identity verification and buy USDT with a bank card or a bank transfer. Binance is the exchange people name most often, but any large exchange that serves your country does the same job.

Buy a little more than the price. If the hosting plan costs 40 USDT, buying 45 leaves room for the withdrawal fee and for rounding. Whatever is left stays in your account for next time.

Where you live matters. Several large exchanges have stopped selling USDT to customers in the European Economic Area, so a buyer there may need a platform that still offers it, or may ask the seller whether another stablecoin will do.

The other route is P2P: buying USDT directly from another person on a marketplace inside an exchange, which holds the seller's USDT until you pay. It works where card purchases do not, and it is also where first-time buyers get cheated most, so read up on buying USDT from a person on P2P without getting scammed.

Which network: what TRC20 and the other labels mean

USDT exists on several blockchains at once: TRON, Ethereum, BNB Chain, Solana and others. Each version of USDT moves only inside its own network. A transfer sent on one network never lands on another.

The labels sellers attach to "USDT" are the names of those versions:

• TRC20 is USDT on TRON. It is the most common choice for payments; addresses start with the letter T, and the network fee is paid in TRX.
• ERC20 is USDT on Ethereum. Addresses start with 0x, and the network fee is paid in ETH.
• BEP20 is USDT on BNB Chain. Addresses also start with 0x, and the network fee is paid in BNB.

Notice that ERC20 and BEP20 addresses look exactly alike. The address alone does not tell you the network, so the seller has to.

How do you know which network the seller accepts? On a checkout page, the network name stands next to the address. When a person sends you just an address, ask them to name the network before you pay: "USDT TRC20" is a complete instruction, a bare "USDT" is not.

If the seller accepts several networks and leaves the choice to you, take the one you already hold USDT on. When you are buying from scratch, it is worth comparing how the USDT networks differ and which one is cheaper for the sender.

Can I pay straight from an exchange, without a wallet of my own?

Yes. An exchange account can send USDT to any address. The exchange calls it a withdrawal, but for the seller it is an ordinary payment.

Paying from an exchange differs from paying from a wallet app in three ways:

• The exchange takes a withdrawal fee from the amount you type. Type 40 and slightly less than 40 arrives, so look for the line showing the amount the recipient will receive and raise your figure until it matches the price.
• The fee is charged in USDT. You do not need to hold TRX or ETH: the exchange pays the network and bills you in USDT.
• The first withdrawal can take longer. Exchanges sometimes hold a withdrawal for a security check, especially on a new account or to a new address, so do not leave a timed checkout to its last minutes.

A wallet app of your own, such as Trust Wallet or TronLink, works too. You send USDT from it directly, but then the network fee comes out of your own balance of the network's coin, which is the next question.

How to pay with USDT on Binance

The route on Binance, and on most other exchanges, runs in five steps:

1. Open the USDT withdrawal screen. In the Binance app, go to your wallet, choose Withdraw, pick USDT and choose sending it over the crypto network.
2. Paste the seller's address into the address field. Copy it from the checkout page or from the seller's message.
3. Choose the network the seller named. Binance lists every network it supports for USDT; for a TRC20 address, pick TRON (TRC20).
4. Type an amount that leaves the full price after the fee. Check the amount to be received: it has to equal what the seller asked for.
5. Confirm the withdrawal with your security codes. Binance sends the USDT, and the transfer appears in your withdrawal history.

What does sending cost, and why does the wallet want TRX or ETH?

Every blockchain charges a fee for each transfer, and it charges in its own coin, not in USDT. On TRON the coin is TRX, on Ethereum it is ETH, on BNB Chain it is BNB. You can hold 500 USDT in a wallet app and still send none of it while the TRX balance is zero. If your wallet has already refused on exactly that, here is what to do when there is not enough TRX to send USDT.

As of September 2026, one USDT transfer on TRON burns about 6.5 TRX when the recipient's address already holds USDT, and about 13 TRX when it holds none. At recent TRX prices that comes to a few dollars. On other networks the fee rises and falls with how busy the network is, and the wallet shows it before you confirm.

So before paying from your own wallet, put some of the network's coin next to your USDT. Around 15 TRX covers one TRON transfer to any address.

How to pay someone with USDT

Paying a person, such as a freelancer, is the case with the least protection: no checkout checks the amount or the network for you. These steps cover it:

1. Get the address and the network in writing. Ask the person to send a message like "USDT, TRC20" followed by the address; a message beats something read out on a call.
2. Copy the address from that message, never from your transfer history. Scammers send tiny transfers from addresses whose first and last characters match ones you have used, so a fake one sits in your history looking familiar. The trick is called address poisoning, and it pays to know how scammers plant a look-alike address in your wallet history.
3. Compare the pasted address against the message. Check the first four characters, the last four and a few in the middle.
4. Choose the same network the person named. In a wallet app, that means sending from the USDT on that network; on an exchange, it means picking that network on the withdrawal screen.
5. Send a small test payment when the amount is large. Paying a freelancer 800 USDT, send 5 first and wait for them to confirm it arrived; the test costs one extra fee, which is worth it for 800 and not for a 10-dollar VPN.
6. Send the rest and keep the transaction hash. It is your receipt, and the section after next explains what to do with it.

How to pay with USDT online at a checkout

A USDT checkout works like an invoice. You choose USDT and a network, and the page shows an amount, an address and, on many checkouts, a QR code and a timer. The order counts as paid when a transfer of that amount reaches that address.

You can pay a checkout in one of three ways:

• Copy the address and the amount. This works from any exchange or wallet app: paste both into the send or withdrawal screen.
• Scan the QR code. A wallet app on your phone reads it and fills in the address, and often the amount.
• Open the payment link in your wallet. Some checkouts offer a button that opens a wallet app with the transfer already prepared, and you only confirm it.

The most common checkout mistake is a short payment. A buyer pays from an exchange, the withdrawal fee comes off, and 39.8 USDT arrives against a 40 USDT invoice. The other two are paying on a different network from the one chosen on the page, and paying after the timer has run out.

Payment services handle a short payment differently: some mark the order as failed, some wait for the rest, some leave it to the seller to sort out by hand. You rarely know in advance which kind you are facing, so the safe habit is to send exactly the amount shown, counted after the fee.

How do I know the payment arrived, and what do I send the seller?

Every transfer gets a transaction hash, also called a TXID: a long string of letters and digits that identifies it on the blockchain. A wallet app shows the hash in the transfer's details; an exchange shows it in the withdrawal history.

Paste the hash into a blockchain explorer, a public website that shows every transfer on a network: Tronscan for TRON, Etherscan for Ethereum, BscScan for BNB Chain. It shows the status, the amount and the recipient's address, so you can see for yourself that the money reached the right place. Here is how to check a transaction by its hash in a blockchain explorer.

Send the seller the hash, the amount, the network and the order or invoice number if there is one. A screenshot of your balance proves nothing; the hash does.

If the explorer shows the transfer delivered to the right address and the seller still sees nothing, the seller is usually looking at a different network or a different wallet. The hash settles the question in a minute.

Is paying with USDT safe, and can a payment be reversed?

The network itself is reliable; the risks come from mistakes and from people. A USDT payment cannot be reversed: there is no chargeback, no bank dispute and no support line with an undo button. Money comes back only if the recipient chooses to send it back.

So how safe a payment is depends on who is on the other end:

• A business with a real checkout. The risk is the same as any online purchase from an unfamiliar shop: check that the site is the real one before paying.
• A person you already work with. Send a test payment first, and split a large job into stages paid as the work arrives.
• A stranger who wants USDT and wants it now. Refusing cards, offering a discount for crypto and pushing you to hurry are the usual signs of a scam; a freelance platform that holds the money until the work is delivered is the safer route.

How to pay a CryptumPay invoice, step by step

Some sellers take USDT through CryptumPay, a crypto payment service. As a buyer you meet it in one of two ways: the seller creates an invoice in the CryptumPay console and sends you the payment link by email, chat or any other channel, or a button on the seller's site opens the full CryptumPay checkout in a window. You do not need a CryptumPay account: you open the payment link and pay directly from your crypto wallet.

Have your USDT ready before you start, together with the network's coin for the fee if you pay from a wallet app. The CryptumPay window takes you from the opened link to "Paid" in six steps:

1. Open the CryptumPay payment link, or press the pay button on the seller's site. The CryptumPay window opens with your invoice; if it shows up in the wrong language, the window has a RU/EN switch.
2. Choose the coin and the network in the CryptumPay window. Pick the combination you actually hold, for example USDT on TRON; some coins carry a minimum amount, which is worth checking before you settle on one. On the same screen, before "Proceed to payment", you can tick "Send email notification" and type your address into the "Your email" field that appears.
3. Read the "To pay (incl. fee)" line in the CryptumPay window. When the seller has passed fees on to the buyer, the line comes with a breakdown: the invoice amount, a transfer fee for servicing a one-time deposit address in the network you chose, and a CryptumPay service fee of 1% of the invoice amount, so a 40 USDT invoice carries a 0.40 USDT service fee on top.
4. Send exactly that amount on the CryptumPay screen "Send the exact amount to the specified address". The screen shows a QR code, the address and the amount, each with a copy button, and a countdown timer; scan the QR code with a wallet app or use the copy buttons rather than retyping, and if you pay from an exchange, add its withdrawal fee on top so the full amount arrives.
5. Wait for "Payment found and processing" in the CryptumPay window. This status means the transfer has reached the address, and a counter shows how many network checks it has passed so far.
6. Keep the "Paid" screen from CryptumPay. It ends the payment with a summary. Keep the transaction hash from your wallet or exchange as well: it is still your own proof of the transfer.

CryptumPay lets the seller set a tolerance in percent, and the invoice treats a wrong amount according to it. Say a withdrawal fee leaves 39.8 USDT against a 40 USDT invoice: if that difference is within the seller's tolerance, the payment confirms automatically; if it is beyond, the CryptumPay checkout asks you to pay the remaining amount. If you sent more than the invoice asked, you can request the excess back from the same CryptumPay checkout.

What it comes down to

Paying with USDT means sending a stated amount to a stated address on a stated network. Get the network in writing, copy the address from the source and compare it, and check the amount the recipient will actually receive.

From an exchange, watch the withdrawal fee; from a wallet app, keep the network's coin for the fee. After sending, keep the transaction hash: it is your receipt and your proof.

Questions people also ask

How long does a USDT TRC20 transfer take?

TRON adds a new block about every three seconds, so a transfer usually shows as confirmed in the explorer within a minute. An exchange receiving the money may wait for extra confirmations and credit it a few minutes later. When a payment seems slow, the delay is usually on the sending exchange's side, before the transfer reaches the network.

Sent USDT to the wrong address — can I get it back?

Only if whoever controls that address sends it back; nobody can reverse the transfer for them. If the address belongs to an exchange, write to that exchange's support with the transaction hash, though a result is not guaranteed. If you sent ERC20 USDT to a BEP20 address in your own wallet app, or the other way round, the tokens are usually still yours: turn on the other network in the wallet and they appear.

Can I pay with USDT on Amazon?

Not directly: Amazon does not accept crypto at checkout. The usual workaround is an Amazon gift card bought for USDT from a third-party gift card service, whose balance you then spend on Amazon. Check the service's reputation first, and buy a card for the Amazon store of your own country, because cards work only in the store they were issued for.

How do I pay with USDT on Revolut?

In countries where Revolut offers USDT, open the crypto section, choose USDT, choose Send to an external address, pick Ethereum or TRON to match the seller's network and paste the address. Customers in the European Economic Area and Switzerland cannot do this: Revolut ended USDT support for them by 31 August 2026.

What is the Binance fee to send USDT?

It depends on the network you choose, and Binance shows the exact fee on the withdrawal screen before you confirm. The fee is a flat amount in USDT per withdrawal, not a percentage of the payment. If the person you pay also has a Binance account, sending USDT to their Binance ID through Binance Pay skips the blockchain and is free for everyday amounts.
