The figure is indicative; the exact amount is locked in the order.

One ETH Arbitrum buys 0.999 ETH Optimism right now; the other way round, 1 ETH Optimism is 1.001 ETH Arbitrum. Market over 24 hours: ETH Arbitrum against ETH Optimism a move of 0%. The week added a move of 0%.

The weekly corridor ran from 1 to 1 ETH Optimism, a spread of 0%. A single order takes 2.95 to 4,080 ETH Arbitrum. In dollars that is roughly $7,229.98.

The payout leaves in the Optimism network, so the receiving address has to belong to that network.

Who takes the ETH Arbitrum → ETH Optimism route

  • Moving between networksETH in Arbitrum One (fee ≈ $0.001) becomes Optimism (fee ≈ < $0.0001) — the usual way to top up a wallet or an exchange that speaks one network only.
  • A road both waysThe ETH Optimism → ETH Arbitrum direction is open too, so going back into ETH takes the same route.

How the ETH Arbitrum → ETH Optimism order runs

  1. Work out the amount in the calculator: orders start at 2.95 ETH Arbitrum.
  2. Enter a ETH address in Optimism and a way to reach you.
  3. Send ETH Arbitrum in Arbitrum One for exactly the amount stated in the order.
  4. Once the network confirms your transfer, Ethereum Optimism leaves for your address. The order page tracks every step.

Swap ETH Arbitrum for ETH Optimism

Check this before sending ETH Arbitrum

  • The address network is Optimism. Sending through another network usually means losing the transfer.
  • The transfer must not be smaller than 2.95 ETH Arbitrum.
  • Copy the address whole, then compare the first and last characters after pasting.
  • Ethereum, Arbitrum, Optimism, BNB Smart Chain and Polygon all use the same address shape (0x…). Make sure the wallet is switched to OP Mainnet (Optimism).
  • Coins go through an AML check: a flagged transfer can be held until the check is finished.

Common questions: ETH Arbitrum → ETH Optimism

What rate does ETH Arbitrum to ETH Optimism run at?
As of Sep 17, 2026 23:58 it is 1 ETH Arbitrum = 0.999 ETH Optimism. The figure recalculates on its own, and the calculator always shows the fresh one. In dollars that is around $2,448.39.
What amounts does ETH Arbitrum → ETH Optimism accept?
From 2.95 to 4,080 ETH Arbitrum per order. The lower limit is roughly $7,229.98.
Where does the 2.95 ETH Arbitrum floor come from?
Network fees and order handling eat a small transfer alive — below 2.95 ETH Arbitrum 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 ETH Arbitrum, and that one goes to the blockchain, not to us.
How long does ETH Arbitrum to ETH Optimism take?
The clock starts with confirmations: the order goes into work once Arbitrum One confirms your transfer. After that it comes down to how busy the network is. A block in Arbitrum One closes in about 0.25 sec.
Will native ETH arrive, or a wrapper?
Native. ETH Optimism is the network's own coin in OP Mainnet (Optimism), and its fees are paid in it too.
Do I need ETH to receive ETH Optimism?
No. Fees in OP Mainnet (Optimism) are paid in ETH Optimism, so no separate coin is needed.
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 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 ETH Arbitrum to ETH Optimism rate do this month?
The month came in at a move of 0%. Low 1, high 1, middle 1 ETH Optimism per ETH Arbitrum.
Can I go back, ETH Optimism to ETH Arbitrum?
Yes, the reverse direction is open: 1 ETH Optimism = 0.999 ETH Arbitrum. The link sits right under the calculator.
