The figure is indicative; the exact amount is locked in the order.
The direction runs at 0.0000304383 ETH Optimism per ERA, or 32,853.32 ERA per ETH Optimism. Market over 24 hours: ERA against ETH Optimism minus 2.56%. The week added minus 6.17%.
The weekly corridor ran from 0.000028693 to 0.0000414551 ETH Optimism, a spread of 44.48%. A single order takes 3,623.19 to 148,000,000 ERA. In dollars that is roughly $244.42.
The payout leaves in the Optimism network, so the receiving address has to belong to that network. By market cap Caldera sits 1153th ($11.81 M) and Ethereum 2th ($277.76 B). Daily moves of ERA and ETH over 90 days line up at 0.07 (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 0.07 (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.
