- Work out the amount in the calculator — orders start at 837.5208 ZRX.
- Give a USDT address on Ethereum (ERC20) and a contact for the order.
- Send ZRX on 0x Protocol, exactly the amount the order shows.
- Nothing else is needed from you: as soon as the network confirms the transfer, the robot sends Tether to your address. The order page shows the status.

- The address network is Ethereum (ERC20). Sending through another network almost always means losing the transfer.

What amounts does ZRX → USDT ERC20 accept?

Which network is cheaper for receiving USDT?
Usually USDT BEP20, USDT SOL, USDT Arbitrum, USDT AVAX C, USDT Optimism works out cheaper. Still, the network is picked by what the recipient accepts, not by the fee.
What happens if the rate moves while I am paying?
Nothing: the rate is locked in the order and holds for as long as the order is alive. It is recalculated only if the payment arrives late or for a different amount — so send the exact sum, and send it promptly.
