Who takes the ETH Optimism → ADA route
- Fuel for CardanoWithout Cardano nothing moves in Cardano — every transfer and every contract call is paid in it.
- Different basketsDaily moves of ETH and ADA 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 ADA → ETH Optimism direction is open too, so going back into ETH takes the same route.

How the ETH Optimism → ADA order runs
- Work out the amount in the calculator: orders start at 0.012 ETH Optimism.
- Enter a ADA address in Cardano and a way to reach you.
- Send ETH Optimism in Optimism for exactly the amount stated in the order.
- Once the network confirms your transfer, Cardano leaves for your address. The order page tracks every step.
Check this before sending ETH Optimism
- The address network is Cardano. Sending through another network usually means losing the transfer.
- The transfer must not be smaller than 0.012 ETH Optimism.
- 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: ETH Optimism → ADA
What rate does ETH Optimism to ADA run at?
As of Sep 17, 2026 17:03 it is 1 ETH Optimism = 12,318.95 ADA. The figure recalculates on its own, and the calculator always shows the fresh one. In dollars that is around $2,471.16.
What amounts does ETH Optimism → ADA accept?
From 0.012 to 4,060 ETH Optimism per order. The lower limit is roughly $29.53.
Where does the 0.012 ETH Optimism floor come from?
Network fees and order handling eat a small transfer alive — below 0.012 ETH Optimism 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 ETH Optimism, and that one goes to the blockchain, not to us.
How long does ETH Optimism to ADA take?
The clock starts with confirmations: the order goes into work once Optimism confirms your transfer. After that it comes down to how busy the network is. A block in Optimism closes in about 12 sec.
Which network will ADA arrive in?
Cardano leaves in its own Cardano network — a plain ADA address is all you need.
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 ETH Optimism to ADA rate do this month?
The month came in at plus 14.17%. Low 10,719.07, high 12,540.71, middle 11,658.73 ADA per ETH Optimism.
Can I go back, ADA to ETH Optimism?
Yes, the reverse direction is open: 1 ADA = 0.0000817463 ETH Optimism. The link sits right under the calculator.
