Preliminary figure: the final amount is locked in the order.

The direction is holding at 0.179002 USDT Optimism per 1 ADA (5.5865 ADA per 1 USDT Optimism). Over 24 hours ADA/USDT Optimism came in at plus 4.09%. Over the week, minus 4.22%.

The weekly range ran from 0.173451 to 0.199969 USDT Optimism, a spread of 15.29%. One order takes from 783.6254 to 55,800,000 ADA. In dollars that is roughly $140.47.

  • The address network is Optimism. Sending through another network almost always means losing the transfer.
  • The transfer must not be smaller than 783.6254 ADA.

Common questions: ADA → USDT Optimism

What rate does ADA to USDT Optimism run at?
As of Nov 10, 2026 13:19 it is 1 ADA = 0.179002 USDT Optimism. The figure updates on its own, and the calculator always shows the current one. On the market that is around $0.178839.
What amounts does ADA → USDT Optimism accept?
From 783.6254 to 55,800,000 ADA per order. The floor is roughly $140.47.
Why can I not swap less than 783.6254 ADA?
The network fee and the handling do not depend on the amount. On a transfer below 783.6254 ADA 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 ADA, and the blockchain takes that one.
How long does swapping ADA for USDT Optimism take?
The clock starts with confirmations: as soon as Cardano 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. A block in Cardano closes in about 20 sec.
Which network will USDT Optimism arrive in?
The payout goes out on Optimism. Check that the receiving wallet supports that network.
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.
What did the ADA to USDT Optimism rate do over the month?
Over the month, minus 27.95%: a low of 0.175167, a high of 0.252257, an average of 0.210697 USDT Optimism per 1 ADA.
