The figure is indicative; the exact amount is locked in the order.
One ADA buys 0.0000824796 ETH Optimism right now; the other way round, 1 ETH Optimism is 12,124.21 ADA. Market over 24 hours: ADA against ETH Optimism plus 2.47%. The week added minus 5.83%.
The weekly corridor ran from 0.0000799994 to 0.0000865953 ETH Optimism, a spread of 8.24%. A single order takes 405.2006 to 49,500,000 ADA. In dollars that is roughly $81.91.
The payout leaves in the Optimism network, so the receiving address has to belong to that network. By market cap Cardano sits 19th ($7.58 B) and Ethereum 2th ($301.08 B). Daily moves of ADA and ETH over 90 days line up at 0.77 (they travel together).
Who takes the ADA → ETH Optimism route
- Fuel for OptimismWithout Ethereum nothing moves in Optimism — every transfer and every contract call is paid in it.
- Different basketsDaily moves of ADA and ETH over 90 days line up at 0.77 (they travel together) — the looser the link, the less a portfolio depends on one coin.
- A road both waysThe ETH Optimism → ADA direction is open too, so going back into ADA takes the same route.

Payout network for ETH
The same ETH goes out in several networks. Rates and lower limits differ, and the fee is charged by the network itself.

How the ADA → ETH Optimism order runs
- Work out the amount in the calculator: orders start at 405.2006 ADA.
- Enter a ETH address in Optimism and a way to reach you.
- Send ADA in Cardano for exactly the amount stated in the order.
- Once the network confirms your transfer, Ethereum leaves for your address. The order page tracks every step.
Check this before sending ADA
- The address network is Optimism. Sending through another network usually means losing the transfer.
- The transfer must not be smaller than 405.2006 ADA.
- Copy the address whole, then compare the first and last characters after pasting.
- Coins go through an AML check: a flagged transfer can be held until the check is finished.

Common questions: ADA → ETH Optimism
What rate does ADA to ETH Optimism run at?
As of Sep 17, 2026 20:08 it is 1 ADA = 0.0000824796 ETH Optimism. The figure recalculates on its own, and the calculator always shows the fresh one. In dollars that is around $0.203512.
What amounts does ADA → ETH Optimism accept?
From 405.2006 to 49,500,000 ADA per order. The lower limit is roughly $81.91.
Where does the 405.2006 ADA floor come from?
Network fees and order handling eat a small transfer alive — below 405.2006 ADA the swap stops making sense for either side.
What else is taken on top of the rate?
The payout is already calculated at the rate in the calculator. On top of it you only pay the network fee for sending ADA, and that one goes to the blockchain, not to us.
How long does ADA to ETH Optimism take?
The clock starts with confirmations: the order goes into work once Cardano confirms your transfer. After that it comes down to how busy the network is. A block in Cardano closes in about 20 sec.
Which network will ETH Optimism arrive in?
The payout leaves in Optimism. Make sure the receiving wallet works with that network.
Where is receiving ETH cheaper?
The cheapest is usually ETH Arbitrum, ETH BEP20, ETH Optimism. Still, the network is chosen by what the recipient supports, not by the fee.
What if the rate moves while I am paying?
The rate is pinned to the order and does not move while the order is alive. It can be recalculated if the payment arrives late or for a different amount — so send the exact sum, and send it promptly.
What did the ADA to ETH Optimism rate do this month?
The month came in at minus 12.41%. Low 0.0000797403, high 0.0000932917, middle 0.0000859465 ETH Optimism per ADA.
Can I go back, ETH Optimism to ADA?
Yes, the reverse direction is open: 1 ETH Optimism = 12,209.43 ADA. The link sits right under the calculator.
