The figure is indicative; the exact amount is locked in the order.
The direction runs at 0.0000234897 ETH Optimism per ERA, or 42,571.9 ERA per ETH Optimism. Market over 24 hours: ERA against ETH Optimism plus 0.11%. The week added minus 3.24%.
The weekly corridor ran from 0.0000220882 to 0.000024216 ETH Optimism, a spread of 9.63%. A single order takes 3,623.19 to 177,000,000 ERA. In dollars that is roughly $204.17.
The payout leaves in the Optimism network, so the receiving address has to belong to that network. By market cap Caldera sits 1207th ($9.85 M) and Ethereum 2th ($296.81 B). Daily moves of ERA and ETH over 90 days line up at 0.11 (they travel apart).
Who takes the ERA → 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 ERA and ETH over 90 days line up at 0.11 (they travel apart) — the looser the link, the less a portfolio depends on one coin.
- A road both waysThe ETH Optimism → ERA direction is open too, so going back into ERA 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 ERA → ETH Optimism order runs
- Work out the amount in the calculator: orders start at 3,623.19 ERA.
- Enter a ETH address in Optimism and a way to reach you.
- Send ERA in Caldera 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 ERA
- The address network is Optimism. Sending through another network usually means losing the transfer.
- The transfer must not be smaller than 3,623.19 ERA.
- 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: ERA → ETH Optimism
What rate does ERA to ETH Optimism run at?
As of Sep 17, 2026 07:58 it is 1 ERA = 0.0000234897 ETH Optimism. The figure recalculates on its own, and the calculator always shows the fresh one. In dollars that is around $0.0571267.
What amounts does ERA → ETH Optimism accept?
From 3,623.19 to 177,000,000 ERA per order. The lower limit is roughly $204.17.
Where does the 3,623.19 ERA floor come from?
Network fees and order handling eat a small transfer alive — below 3,623.19 ERA 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 ERA, and that one goes to the blockchain, not to us.
How long does ERA to ETH Optimism take?
The clock starts with confirmations: the order goes into work once Caldera confirms your transfer. After that it comes down to how busy the network is.
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 BEP20, ETH Arbitrum, 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 ERA to ETH Optimism rate do this month?
The month came in at minus 27.74%. Low 0.0000227639, high 0.0000320345, middle 0.0000246304 ETH Optimism per ERA.
Can I go back, ETH Optimism to ERA?
Yes, the reverse direction is open: 1 ETH Optimism = 42,786.15 ERA. The link sits right under the calculator.
