Optimism (OP 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.

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

Current maths: 0.0000486682 ETH BASE for every OP Optimism, and 20,547.32 OP Optimism per ETH BASE in reverse. Over 24 hours OP Optimism/ETH BASE came in at plus 0.5%. Over the week, minus 1.74%.

The weekly range ran from 0.0000457907 to 0.0000558102 ETH BASE, a spread of 21.88%. One order takes from 772.0092 to 76,700,000 OP Optimism. In dollars that is roughly $100.69.

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. Market capitalisation puts Optimism at No. 153 ($299.94 M) and Ethereum at No. 2 ($325.93 B). Over 90 days the daily moves of OP and ETH correlate at 0.43 (they travel alike).

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 OP Optimism → ETH BASE exchange runs

  1. Work out the amount in the calculator — orders start at 772.0092 OP Optimism.
  2. Give a ETH address on BASE and a contact for the order.
  3. Send OP Optimism on Optimism, exactly the amount the order shows.
  4. 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 OP Optimism for ETH BASE

Check this before sending OP Optimism

  • The address network is BASE. Sending through another network almost always means losing the transfer.
  • The transfer must not be smaller than 772.0092 OP 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 OP Optimism → ETH BASE route

  • Fuel for BASEWithout Ethereum you cannot pay for a transfer or a contract call in BASE — the coin is needed for anything that happens in that ecosystem.
  • Different basketsDaily moves of OP and ETH over 90 days link at 0.43 (they travel alike) — the weaker the link, the less a portfolio rests on one coin.
  • It works both waysThe ETH BASE → OP Optimism direction is open as well — going back into OP takes the same route and the same automation.

Common questions: OP Optimism → ETH BASE

What rate does OP Optimism to ETH BASE run at?
As of Sep 30, 2026 10:15 it is 1 OP Optimism = 0.0000486682 ETH BASE. The figure updates on its own, and the calculator always shows the current one. On the market that is around $0.129915.
What amounts does OP Optimism → ETH BASE accept?
From 772.0092 to 76,700,000 OP Optimism per order. The floor is roughly $100.69.
Why can I not swap less than 772.0092 OP Optimism?
The network fee and the handling do not depend on the amount. On a transfer below 772.0092 OP 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 OP Optimism, and the blockchain takes that one.
How long does swapping OP 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.
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 Arbitrum, ETH Optimism, ETH BEP20 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 OP Optimism to ETH BASE rate do over the month?
Over the month, plus 33.97%: a low of 0.0000357733, a high of 0.0000555077, an average of 0.0000432082 ETH BASE per 1 OP Optimism.
Can I swap back, ETH BASE for OP Optimism?
Yes, the reverse is open too: 1 ETH BASE = 20,546.91 OP Optimism. The link to switch sits under the calculator.
