How the COMP → USDT Optimism exchange runs
- Work out the amount in the calculator — orders start at 4.0757 COMP.
- Give a USDT address on Optimism and a contact for the order.
- Send COMP on Compound, 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.
Check this before sending COMP
- The address network is Optimism. Sending through another network almost always means losing the transfer.
- The transfer must not be smaller than 4.0757 COMP.

- Send exactly the amount stated in the order: the automation matches your payment against it, and any difference sends the order back for recalculation.
