Top up with USDT on TRON

Your balance is kept in US dollars and every send is paid from it. You add to it with USDT on the TRON network, and each top up gets its own address and exact amount so it reaches your account by itself.

How a top up works

  1. 1

    Choose an amount

    On the Balance page, pick an amount from $50 to $10,000. One USDT adds one US dollar to your balance.

  2. 2

    Get your address

    You receive a TRON (TRC20) address, a QR code and the exact USDT amount, including a few extra decimals. The decimals are how your payment is matched to your account.

  3. 3

    Send USDT

    Send the exact amount from any wallet or exchange that supports USDT on TRON. Choose the TRC20 network in the withdrawal form.

  4. 4

    Start sending

    When the payment is confirmed and credited, your balance updates and you can start sending. The top up also counts toward your plan.

Tips for a smooth top up

  • Copy the amount with the copy button so every decimal is included.
  • Pick TRON (TRC20) as the network when you withdraw from an exchange.
  • If an exchange charges a withdrawal fee, add it on top so the full amount arrives.
  • Keep the top up code shown on the Balance page. Support can find your payment with it in seconds.

Your balance

Kept in US dollars
Prices, sends, refunds and your plan all use US dollars, so totals are easy to follow.
Never expires
There is no monthly fee and no expiry date. Unused balance stays on your account, and you can ask Support to withdraw it.
Refunds land here
Messages that are not delivered are refunded straight back to your balance, ready for the next send.
