All Knowing
USDT only, on Tron (TRC20), BNB Chain (BEP20) or Ethereum (ERC20). At checkout you pick the network, then get an address that is yours for that order only, the exact amount, and the range we accept — the fee your exchange takes off the top is inside it, so a payment short by a withdrawal fee is still credited in full. Tron is the cheapest and fastest from most exchanges, about a minute. The key is issued the moment the transfer confirms, and the receipt carries the transaction id.
Sent on the wrong network? It does not dead-end; it opens a ticket with the transaction attached. PayPal is there too if you would rather. Go to checkout.
