How the USDT Optimism → SNX exchange runs
- Work out the amount in the calculator — orders start at 100.67 USDT Optimism.
- Give a SNX address on Synthetix 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 Synthetix to your address. The order page shows the status.
Check this before sending USDT Optimism
- The address network is Synthetix. Sending through another network almost always means losing the transfer.
- The transfer must not be smaller than 100.67 USDT Optimism.
- Copy the address in full, then check its first and last characters once it is pasted.
- Send exactly the amount stated in the order: the automation matches your payment against it, and any difference sends the order back for recalculation.

Common questions: USDT Optimism → SNX
What rate does USDT Optimism to SNX run at?
As of Sep 30, 2026 16:50 it is 1 USDT Optimism = 3.9062 SNX. The figure updates on its own, and the calculator always shows the current one. On the market that is around $0.999845.
What amounts does USDT Optimism → SNX 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 SNX 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 SNX arrive in?
Synthetix arrives in its own Synthetix network — a plain SNX 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 SNX rate do over the month?
Over the month, minus 20.61%: a low of 3.7142, a high of 5.0322, an average of 4.483 SNX per 1 USDT Optimism.
