Caldera (ERA) → Ethereum (ETH Optimism)

Q: What rate does ERA to ETH Optimism run at?

As of Oct 1, 2026 01:15 it is 1 ERA = 0.000024747 ETH Optimism. The figure updates on its own, and the calculator always shows the current one. On the market that is around $0.0660229.

Q: What amounts does ERA → ETH Optimism accept?

From 1,502.54 to 150,000,000 ERA per order. The floor is roughly $99.91.

Q: Why can I not swap less than 1,502.54 ERA?

The network fee and the handling do not depend on the amount. On a transfer below 1,502.54 ERA they eat a noticeable share of it, and the swap stops making sense for either side.

Q: 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 ERA, and the blockchain takes that one.

Q: How long does swapping ERA for ETH Optimism take?

The clock starts with confirmations: as soon as Caldera 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.

Q: Which network will ETH Optimism arrive in?

The payout goes out on Optimism. Check that the receiving wallet supports that network.

Q: Which network is cheaper for receiving ETH?

Usually ETH BEP20, ETH Arbitrum, ETH Optimism works out cheaper. Still, the network is picked by what the recipient accepts, not by the fee.

Q: 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.

Q: What did the ERA to ETH Optimism rate do over the month?

Over the month, minus 8.08%: a low of 0.0000228241, a high of 0.0000274601, an average of 0.0000243708 ETH Optimism per 1 ERA.

Q: Can I swap back, ETH Optimism for ERA?

Yes, the reverse is open too: 1 ETH Optimism = 40,408.06 ERA. The link to switch sits under the calculator.

The order runs on autopilot: the rate is locked when you create it, and the payout leaves as soon as the network confirms your transfer. No manual approval, no working hours.

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

Current maths: 0.000024747 ETH Optimism for every ERA, and 40,408.86 ERA per ETH Optimism in reverse. Over 24 hours ERA/ETH Optimism came in at plus 0.48%. Over the week, plus 1.19%.

The weekly range ran from 0.0000245109 to 0.0000265901 ETH Optimism, a spread of 8.48%. One order takes from 1,502.54 to 150,000,000 ERA. In dollars that is roughly $99.91.

The robot sends the payout in the Optimism network, so the address has to belong to that network — a transfer to another one will not arrive. Market capitalisation puts Caldera at No. 1179 ($11.62 M) and Ethereum at No. 2 ($325.78 B). Over 90 days the daily moves of ERA and ETH correlate at 0.1 (they travel apart).

Which network ETH arrives in

The same ETH goes out in several networks. Each has its own rate and its own floor, and the fee is charged by the network itself.

How the ERA → ETH Optimism exchange runs

Work out the amount in the calculator — orders start at 1,502.54 ERA.
Give a ETH address on Optimism and a contact for the order.
Send ERA on Caldera, exactly the amount the order shows.
Nothing else is needed from you: as soon as the network confirms the transfer, the robot sends Ethereum to your address. The order page shows the status.

Swap ERA for ETH Optimism

Check this before sending ERA

The address network is Optimism. Sending through another network almost always means losing the transfer.
The transfer must not be smaller than 1,502.54 ERA.
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.
