The figure is indicative; the exact amount is locked in the order.
Today ETH Optimism goes for 0.999 ETH Arbitrum, and ETH Arbitrum goes for 1.001 ETH Optimism. Market over 24 hours: ETH Optimism against ETH Arbitrum a move of 0%. The week added a move of 0%.
The weekly corridor ran from 1 to 1 ETH Arbitrum, a spread of 0%. A single order takes 2.95 to 4,110 ETH Optimism. In dollars that is roughly $7,174.37.
The payout leaves in the Arbitrum One network, so the receiving address has to belong to that network.
Who takes the ETH Optimism → ETH Arbitrum route
- Moving between networksETH in Optimism (fee ≈ < $0.0001) becomes Arbitrum One (fee ≈ $0.001) — the usual way to top up a wallet or an exchange that speaks one network only.
- A road both waysThe ETH Arbitrum → ETH Optimism direction is open too, so going back into ETH 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.
| Network | Per ETH Optimism | From | Network fee | Speed |
|---|---|---|---|---|
| Arbitrum One open now | 0.999 | 2.95 ETH Optimism | ≈ $0.001 | fast |
| BNB Smart Chain (BEP20) | 0.999 | 2.95 ETH Optimism | ≈ $0.0024 | fast |

How the ETH Optimism → ETH Arbitrum order runs
- Work out the amount in the calculator: orders start at 2.95 ETH Optimism.
- Enter a ETH address in Arbitrum One and a way to reach you.
- Send ETH Optimism in Optimism for exactly the amount stated in the order.
- Once the network confirms your transfer, Ethereum Arbitrum leaves for your address. The order page tracks every step.
Check this before sending ETH Optimism
- The address network is Arbitrum One. Sending through another network usually means losing the transfer.
- The transfer must not be smaller than 2.95 ETH Optimism.
- 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 Arbitrum One.
- Coins go through an AML check: a flagged transfer can be held until the check is finished.
OP Mainnet (Optimism) against Arbitrum One
| OP Mainnet (Optimism) | Arbitrum One | |
|---|---|---|
| Network type | L2, optimistic rollup | L2, optimistic rollup |
| Fees are paid in | ETH | ETH |
| Fee level | ≈ < $0.0001 | ≈ $0.001 |
| Speed | fast | fast |
| Block | ~2 sec | ~0.25 sec |
| Address shape | 0x… | 0x… |
| Memo or tag | not needed | not needed |
| Ethereum-style address (0x…) | yes | yes |
| Official withdrawal to Ethereum | ≈ 7 days (challenge period) | ≈ 7 days (challenge period) |
Fee and speed levels are comparative: both move with how busy the network is.
How this differs from a classic bridge
| RubyCash | Classic bridge | |
|---|---|---|
| What lands at your address | native ETH in Arbitrum One | Depends: in some networks it is the bridged version of the token |
| Wallet and signatures | Not needed: the coins go to the address from the order | Needed: connect the wallet and sign contract transactions |
| A coin for fees in Arbitrum One | Not needed to receive | Often needed, or the funds cannot be claimed or moved on |
| Timing | After confirmations in OP Mainnet (Optimism); the order page tracks it | Depends on the bridge and the load of both networks |
| Who holds the funds meanwhile | RubyCash for the life of the order, with an AML check | The bridge contract or its validators |

Common questions: ETH Optimism → ETH Arbitrum
What rate does ETH Optimism to ETH Arbitrum run at?
As of Sep 17, 2026 08:08 it is 1 ETH Optimism = 0.999 ETH Arbitrum. The figure recalculates on its own, and the calculator always shows the fresh one. In dollars that is around $2,429.56.
What amounts does ETH Optimism → ETH Arbitrum accept?
From 2.95 to 4,110 ETH Optimism per order. The lower limit is roughly $7,174.37.
Where does the 2.95 ETH Optimism floor come from?
Network fees and order handling eat a small transfer alive — below 2.95 ETH Optimism 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 Optimism, and that one goes to the blockchain, not to us.
How long does ETH Optimism to ETH Arbitrum take?
The clock starts with confirmations: the order goes into work once Optimism confirms your transfer. After that it comes down to how busy the network is. A block in Optimism closes in about 2 sec.
Will native ETH arrive, or a wrapper?
Native. ETH Arbitrum is the network's own coin in Arbitrum One, and its fees are paid in it too.
Do I need ETH to receive ETH Arbitrum?
No. Fees in Arbitrum One are paid in ETH Arbitrum, so no separate coin is needed.
Which network will ETH Arbitrum arrive in?
The payout leaves in Arbitrum One. Make sure the receiving wallet works with that network.
Where is receiving ETH cheaper?
The cheapest is usually ETH Arbitrum, ETH BEP20. 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 Optimism to ETH Arbitrum rate do this month?
The month came in at a move of 0%. Low 1, high 1, middle 1 ETH Arbitrum per ETH Optimism.
Can I go back, ETH Arbitrum to ETH Optimism?
Yes, the reverse direction is open: 1 ETH Arbitrum = 0.999 ETH Optimism. The link sits right under the calculator.
