One OP Optimism buys 0.0000497334 ETH Arbitrum right now; the other way round, 1 ETH Arbitrum is 20,107.22 OP Optimism. Market over 24 hours: OP Optimism against ETH Arbitrum plus 0.36%. The week added plus 4.72%.
The weekly corridor ran from 0.0000444198 to 0.0000541637 ETH Arbitrum, a spread of 21.94%. A single order takes 2,157.5 to 88,000,000 OP Optimism. In dollars that is roughly $245.16.
The payout leaves in the Arbitrum One network, so the receiving address has to belong to that network. By market cap Optimism sits 146th ($260.18 M) and Ethereum 2th ($276.28 B). Daily moves of OP and ETH over 90 days line up at 0.62 (they travel alike).
Who takes the OP Optimism → ETH Arbitrum route
- Fuel for Arbitrum OneWithout Ethereum nothing moves in Arbitrum One — every transfer and every contract call is paid in it.
- Different basketsDaily moves of OP and ETH over 90 days line up at 0.62 (they travel alike) — the looser the link, the less a portfolio depends on one coin.
- A road both waysThe ETH Arbitrum → OP Optimism direction is open too, so going back into OP takes the same route.

How the OP Optimism → ETH Arbitrum order runs
- Work out the amount in the calculator: orders start at 2,157.5 OP Optimism.
- Enter a ETH address in Arbitrum One and a way to reach you.
- Send OP Optimism in Optimism 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 OP Optimism
- The address network is Arbitrum One. Sending through another network usually means losing the transfer.
- The transfer must not be smaller than 2,157.5 OP Optimism.
- 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.
