The figure is indicative; the exact amount is locked in the order.
The direction runs at 0.0000721903 ETH Optimism per ARB, or 13,852.27 ARB per ETH Optimism. Market over 24 hours: ARB against ETH Optimism minus 0.31%. The week added plus 1.87%.
The weekly corridor ran from 0.0000679257 to 0.0000743381 ETH Optimism, a spread of 9.44%. A single order takes 1,258.65 to 61,000,000 ARB. In dollars that is roughly $206.28.
The payout leaves in the Optimism network, so the receiving address has to belong to that network. By market cap Arbitrum sits 70th ($1.13 B) and Ethereum 2th ($276.73 B). Daily moves of ARB and ETH over 90 days line up at 0.62 (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 0.62 (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.
