Pay with USDT
USDT is the coin most people should use here, for one boring reason: the amount you owe does not move while you are paying it. The catch is that USDT exists on several chains and they are not interchangeable.
What you can buy with USDT
Everything on the site takes USDT, at the same price as any other coin. Browse all categories →
The network is the only thing you can get badly wrong
USDT on Tron, USDT on Ethereum and USDT on Solana are the same asset by name and completely separate in practice. Each has its own addresses. Send one to an address for another and the funds land on a chain where nobody holds the matching key — unrecoverable, by us or anyone else.
The addresses look different, which is your safety net. A Tron address starts with T and is 34 characters. An Ethereum address starts with 0x and is 42. A Solana address has no prefix at all. If your exchange is set to one and the payment page shows the other, stop.
Which network to pick
Tron or Solana for almost everything. Their fees are small and roughly fixed, so a $25 order does not pay a disproportionate fee.
Ethereum only if that is where your USDT already sits and moving it would cost more than paying from it. The fee there is set by demand for block space, which means the same transfer can cost cents one day and a great deal more the next.
Why the price does not move
USDT is intended to hold a value of one US dollar, so a $115 order costs about 115 USDT whenever you pay it. With Bitcoin or Ethereum the number of coins you owe is calculated at the moment of quoting and the market keeps moving underneath it — which is why quotes expire.
With a stablecoin that pressure largely disappears. The quote still expires, but the number you are sending is the number you expected.
Watch the withdrawal fee
This causes more underpayments than anything else. Exchanges deduct their withdrawal fee from the amount you asked to send, so requesting exactly the quoted figure delivers slightly less than the quote.
Enter the quoted amount as what should arrive and let the exchange add its fee on top, or simply send a little more. An underpayment is recoverable — you send the difference or get refunded — but it is an avoidable round trip.
When not to pay with USDT
If you hold no stablecoin and would have to buy one first. Swapping into USDT to avoid price movement on a small order can cost more than the movement would have.
Questions
Which USDT network is cheapest?
Tron and Solana. Their fees are small and roughly fixed rather than scaling with network demand, which makes them the sensible default for ordinary order sizes.
I sent USDT on the wrong network. Can it be recovered?
Almost never. The funds exist on a chain where the receiving address has no matching key. Treat the network dropdown as the most important field on the withdrawal screen.
Why did my payment come up short?
Your exchange almost certainly deducted its withdrawal fee from the amount you entered. Send the quoted figure as the amount that should arrive, or add a small margin.
Is USDC accepted too?
Yes, on the networks listed at checkout. The same rule applies — match the network exactly.
