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.

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 Arbitrum | From | Network fee | Speed |
|---|---|---|---|---|
| BNB Smart Chain (BEP20) | 0.999 | 2.95 ETH Arbitrum | ≈ $0.0024 | fast |
| Optimism open now | 0.999 | 2.95 ETH Arbitrum | ≈ < $0.0001 | fast |

How the ETH Arbitrum → ETH Optimism order runs
- Work out the amount in the calculator: orders start at 2.95 ETH Arbitrum.
- Enter a ETH address in Optimism and a way to reach you.
- Send ETH Arbitrum in Arbitrum One for exactly the amount stated in the order.
- Once the network confirms your transfer, Ethereum Optimism leaves for your address. The order page tracks every step.
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.
Arbitrum One against OP Mainnet (Optimism)
| Arbitrum One | OP Mainnet (Optimism) | |
|---|---|---|
| Network type | L2, optimistic rollup | L2, optimistic rollup |
| Fees are paid in | ETH | ETH |
| Fee level | ≈ $0.001 | ≈ < $0.0001 |
| Speed | fast | fast |
| Block | ~0.25 sec | ~2 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 OP Mainnet (Optimism) | 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 OP Mainnet (Optimism) | Not needed to receive | Often needed, or the funds cannot be claimed or moved on |
| Timing | After confirmations in Arbitrum One; 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 |
