The figure is indicative; the exact amount is locked in the order.
The direction runs at 0.0000736664 ETH Optimism per ARB, or 13,574.71 ARB per ETH Optimism. Market over 24 hours: ARB against ETH Optimism plus 1.93%. The week added plus 7.04%.
The weekly corridor ran from 0.0000528293 to 0.0000703704 ETH Optimism, a spread of 33.2%. A single order takes 1,258.65 to 59,700,000 ARB. In dollars that is roughly $210.66.
The payout leaves in the Optimism network, so the receiving address has to belong to that network. By market cap Arbitrum sits 71th ($1.13 B) and Ethereum 2th ($301.08 B). Daily moves of ARB and ETH over 90 days line up at 0.65 (they travel alike).
Who takes the ARB → 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 ARB and ETH over 90 days line up at 0.65 (they travel alike) — the looser the link, the less a portfolio depends on one coin.
- A road both waysThe ETH Optimism → ARB direction is open too, so going back into ARB 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 ARB → ETH Optimism order runs
- Work out the amount in the calculator: orders start at 1,258.65 ARB.
- Enter a ETH address in Optimism and a way to reach you.
- Send ARB in Arbitrum 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 ARB
- The address network is Optimism. Sending through another network usually means losing the transfer.
- The transfer must not be smaller than 1,258.65 ARB.
- 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: ARB → ETH Optimism
What rate does ARB to ETH Optimism run at?
As of Sep 17, 2026 22:03 it is 1 ARB = 0.0000736664 ETH Optimism. The figure recalculates on its own, and the calculator always shows the fresh one. In dollars that is around $0.181766.
What amounts does ARB → ETH Optimism accept?
From 1,258.65 to 59,700,000 ARB per order. The lower limit is roughly $210.66.
Where does the 1,258.65 ARB floor come from?
Network fees and order handling eat a small transfer alive — below 1,258.65 ARB 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 ARB, and that one goes to the blockchain, not to us.
How long does ARB to ETH Optimism take?
The clock starts with confirmations: the order goes into work once Arbitrum 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 ARB to ETH Optimism rate do this month?
The month came in at plus 71.2%. Low 0.0000348501, high 0.0000753115, middle 0.0000495115 ETH Optimism per ARB.
Can I go back, ETH Optimism to ARB?
Yes, the reverse direction is open: 1 ETH Optimism = 13,643.03 ARB. The link sits right under the calculator.
