Pay with USDT (TRC-20)
Pay a Rack4 invoice in USDT on the Tron network: the steps, the one network that works, the exact amount, and what happens if a payment goes wrong.
You can pay any Rack4 invoice in USDT (Tether) on the Tron network, also called TRC-20. Invoices stay priced in US dollars; the checkout works out the USDT amount when you open it. USDT goes through BTCPay Server, the same payment server we run ourselves for Bitcoin, so there's no payment company between you and us.
Send it on Tron (TRC-20) only
USDT exists on many networks: Tron, Ethereum, BNB Smart Chain, Solana and more. Our checkout takes Tron (TRC-20) only. USDT sent on any other network, even to an address that looks right, can't be recovered.
When you withdraw from an exchange, pick TRC-20 or Tron (TRX) as the network. In a wallet, send from your Tron account. A Tron address starts with T.
Tron charges its network fee in TRX, not USDT. Keep a little TRX in the wallet you send from, or let your exchange take its withdrawal fee, so the full USDT amount arrives.
Paying an invoice
- Place an order, or open any invoice under billing in the panel.
- Choose pay with USDT (TRC-20). BTCPay's checkout opens with the USDT amount, a Tron address and a QR code.
- Send exactly that amount, in one payment, to that address.
- Once the payment confirms on Tron (usually under a minute), the invoice shows as paid and we start building your server.
The checkout only lasts a limited time, which it shows you. If it runs out before you've paid, go back to the invoice and choose pay with USDT (TRC-20) again for a fresh one, with a fresh address. Never reuse an address from an old checkout.
If you'd opened a Bitcoin checkout for the same invoice first, that's fine: choosing USDT makes a separate USDT checkout, and you pay whichever one you like. Pay only one of them. If both get paid, the second payment becomes account credit.
You can also add funds or buy a gift card with USDT, the same way.
Exact amounts
Send the amount the checkout shows, to the cent. A payment a cent or two short of the invoice, from rounding, still pays it. Anything more than that short doesn't pay the invoice: the dollar value of what arrived becomes account credit, and we email you with what's left to pay. Choose pay with USDT (TRC-20) again for a checkout for the rest.
If you send too much, the extra becomes account credit.
A payment went wrong
Don't pay a second time. First check the invoice in the panel:
- You paid after the checkout ran out. If the full amount arrives, it still pays the invoice, as long as the invoice is open and its order or server is still there. Otherwise the dollar value we received becomes account credit. Either way we email you to say which.
- You paid only part of it. The dollar value of what arrived becomes account credit and goes straight to the invoice, so you only owe the rest.
- You sent USDT on the wrong network. We can't see or recover it. Contact the exchange or wallet you sent from.
- Anything else: open a support ticket with the invoice number (it looks like
R4-000123) and the Tron transaction ID from your wallet or exchange.
Refunds
The money-back guarantee covers a first order paid in USDT too. USDT refunds are never sent automatically: you choose account credit, or give us a Tron (TRC-20) address of yours in the ticket and we send the USDT there by hand. Give an address you control. An exchange deposit address may not credit you, so don't give the address you paid from unless it's your own wallet. The refund is the invoice's amount in US dollars, sent as USDT at the rate on the day we send it, and the email we send you has the transaction ID.
