ETH: changing network from OP Mainnet (Optimism) to Arbitrum One
It is still ETH, only in a different blockchain: you send ETH Optimism, and the payout of ETH Arbitrum goes to your address in Arbitrum One. Bridge contracts, signatures and wrapped tokens play no part.

The direction is holding at 0.99999 ETH Arbitrum per 1 ETH Optimism (1 ETH Optimism per 1 ETH Arbitrum). Over 24 hours ETH Optimism/ETH Arbitrum came in at about 0%. Over the week, about 0%.
The weekly range ran from 1 to 1 ETH Arbitrum, a spread of 0%. One order takes from 0.037454 to 3,730 ETH Optimism. In dollars that is roughly $100.36.
The robot sends the payout in the Arbitrum One 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 Arbitrum exchange runs
- Work out the amount in the calculator — orders start at 0.037454 ETH Optimism.
- Give a ETH address on Arbitrum One 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 Arbitrum to your address. The order page shows the status.
Check this before sending ETH Optimism
- The address network is Arbitrum One. 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.
- Ethereum, Arbitrum, Optimism, BNB Smart Chain and Polygon addresses look the same (0x…) — make sure the wallet is switched to Arbitrum One.
- Send exactly the amount stated in the order: the automation matches your payment against it, and any difference sends the order back for recalculation.

How an exchange differs from an ordinary bridge
| Velorex | Ordinary bridge | |
|---|---|---|
| What arrives at the address | the Arbitrum One network's own coin, ETH | It varies: a number of networks hand out the bridged version of the token |
| Wallet connection and signatures | We do without them: the payout goes to the address from the order | Mandatory: the wallet is connected, contract transactions are signed |
| Is a Arbitrum One coin needed for fees | Not required to receive | As a rule yes, otherwise the funds cannot be claimed or moved on |
| When it arrives | As soon as OP Mainnet (Optimism) gathers confirmations; the status is shown on the order page | Set by the bridge itself and by the load on both networks |
| Who holds the funds on the way | Velorex — until the order is closed by the payout | The smart contract of the bridge or its validators |

Why people take the ETH Optimism → ETH Arbitrum route
- Changing networkETH from Optimism (fee ≈ $0.0001) moves over to Arbitrum One (fee ≈ $0.0014). That is how people top up a wallet or an exchange that takes one network only.
- It works both waysThe ETH Arbitrum → ETH Optimism direction is open as well — going back into ETH takes the same route and the same automation.
Common questions: ETH Optimism → ETH Arbitrum
What rate does ETH Optimism to ETH Arbitrum run at?
As of Sep 30, 2026 20:05 it is 1 ETH Optimism = 0.99999 ETH Arbitrum. The figure updates on its own, and the calculator always shows the current one. On the market that is around $2,679.62.
What amounts does ETH Optimism → ETH Arbitrum accept?
From 0.037454 to 3,730 ETH Optimism per order. The floor is roughly $100.36.
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 Arbitrum 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 2 sec.
Will real ETH be credited, or a wrapper?
Real. ETH Arbitrum is the Arbitrum One network's own coin, and transfers inside it are paid for with the same coin.
Is ETH needed to receive ETH Arbitrum?
No: fees in Arbitrum One are charged in the same ETH Arbitrum, so there is no second coin to hold.
Which network will ETH Arbitrum arrive in?
The payout goes out on Arbitrum One. 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 Arbitrum rate do over the month?
Over the month, about 0%: a low of 1, a high of 1, an average of 1 ETH Arbitrum per 1 ETH Optimism.
Can I swap back, ETH Arbitrum for ETH Optimism?
Yes, the reverse is open too: 1 ETH Arbitrum = 0.99999 ETH Optimism. The link to switch sits under the calculator.
