Ethereum (ETH Optimism) → Ethereum (ETH BASE)
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.

The direction is holding at 0.99999 ETH BASE per 1 ETH Optimism (1 ETH Optimism per 1 ETH BASE). Over 24 hours ETH Optimism/ETH BASE came in at about 0%. Over the week, about 0%.
The weekly range ran from 1 to 1 ETH BASE, a spread of 0%. One order takes from 0.037454 to 3,710 ETH Optimism. In dollars that is roughly $100.88.
The robot sends the payout in the BASE network, so the address has to belong to that network — a transfer to another one will not arrive.
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 ETH Optimism → ETH BASE exchange runs
- Work out the amount in the calculator — orders start at 0.037454 ETH Optimism.
- Give a ETH address on BASE and a contact for the order.
- Send ETH Optimism on Optimism, exactly the amount the order shows.
- Nothing else is needed from you: as soon as the network confirms the transfer, the robot sends Ethereum BASE to your address. The order page shows the status.
Check this before sending ETH Optimism
- The address network is BASE. Sending through another network almost always means losing the transfer.
- The transfer must not be smaller than 0.037454 ETH Optimism.
- 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.

Why people take the ETH Optimism → ETH BASE route
- Changing networkETH from Optimism (fee ≈ < $0.0001) moves over to BASE (fee —). That is how people top up a wallet or an exchange that takes one network only.
- It works both waysThe ETH BASE → ETH Optimism direction is open as well — going back into ETH takes the same route and the same automation.
Common questions: ETH Optimism → ETH BASE
What rate does ETH Optimism to ETH BASE run at?
As of Sep 30, 2026 16:55 it is 1 ETH Optimism = 0.99999 ETH BASE. The figure updates on its own, and the calculator always shows the current one. On the market that is around $2,693.53.
What amounts does ETH Optimism → ETH BASE accept?
From 0.037454 to 3,710 ETH Optimism per order. The floor is roughly $100.88.
Why can I not swap less than 0.037454 ETH Optimism?
The network fee and the handling do not depend on the amount. On a transfer below 0.037454 ETH Optimism they eat a noticeable share of it, and the swap stops making sense for either side.
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 ETH Optimism, and the blockchain takes that one.
How long does swapping ETH Optimism for ETH BASE take?
The clock starts with confirmations: as soon as Optimism 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. A block in Optimism closes in about 12 sec.
Which network will ETH BASE arrive in?
The payout goes out on BASE. Check that the receiving wallet supports that network.
Which network is cheaper for receiving ETH?
Usually ETH BEP20, ETH Arbitrum works out cheaper. Still, the network is picked by what the recipient accepts, not by the fee.
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.
What did the ETH Optimism to ETH BASE rate do over the month?
Over the month, about 0%: a low of 1, a high of 1, an average of 1 ETH BASE per 1 ETH Optimism.
Can I swap back, ETH BASE for ETH Optimism?
Yes, the reverse is open too: 1 ETH BASE = 0.99999 ETH Optimism. The link to switch sits under the calculator.
