- Give a ZRX address on 0x Protocol and a contact for the order.
- Send USDT Optimism on Optimism, exactly the amount the order shows.
- Nothing else is needed from you: as soon as the network confirms the transfer, the robot sends 0x Protocol to your address. The order page shows the status.

Common questions: USDT Optimism → ZRX
What rate does USDT Optimism to ZRX run at?
As of Sep 30, 2026 15:45 it is 1 USDT Optimism = 8.2034 ZRX. The figure updates on its own, and the calculator always shows the current one. On the market that is around $0.996971.
What amounts does USDT Optimism → ZRX accept?
From 100.67 to 10,000,000 USDT Optimism per order. The floor is roughly $100.63.
Why can I not swap less than 100.67 USDT Optimism?
The network fee and the handling do not depend on the amount. On a transfer below 100.67 USDT Optimism they eat a noticeable share of it, and the swap stops making sense for either side.
Is anything charged on top of the rate?
No. The payout is already worked out at the rate in the calculator. Separately you pay only the network fee for sending USDT Optimism, and the blockchain takes that one.
How long does swapping USDT Optimism for ZRX take?
The clock starts with confirmations: as soon as Optimism confirms your transfer, the order goes out for payout with no operator involved. After that the timing is set by how busy the network is — which is the difference between quick and instant.
Which network will ZRX arrive in?
0x Protocol arrives in its own 0x Protocol network — a plain ZRX address is all you need.
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.
What did the USDT Optimism to ZRX rate do over the month?
Over the month, minus 19.35%: a low of 7.82, a high of 10.6825, an average of 9.2377 ZRX per 1 USDT Optimism.
