The weekly corridor ran from 30.2201 to 31.6748 ETH Optimism, a spread of 4.81%. A single order takes 0.00129399 to 131 BTC. In dollars that is roughly $99.01.
The payout leaves in the Optimism network, so the receiving address has to belong to that network. By market cap Bitcoin sits 1th ($1.54 T) and Ethereum 2th ($299.08 B). Daily moves of BTC and ETH over 90 days line up at 0.9 (they travel together).
Who takes the BTC → 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 BTC and ETH over 90 days line up at 0.9 (they travel together) — the looser the link, the less a portfolio depends on one coin.
- A road both waysThe ETH Optimism → BTC direction is open too, so going back into BTC 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 BTC | From | Network fee | Speed |
|---|---|---|---|---|
| Arbitrum One | 31.3754 | 0.00129399 BTC | ≈ $0.001 | fast |

How the BTC → ETH Optimism order runs
- Work out the amount in the calculator: orders start at 0.00129399 BTC.
- Enter a ETH address in Optimism and a way to reach you.
- Send BTC in Bitcoin 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 BTC
- The address network is Optimism. Sending through another network usually means losing the transfer.
- The transfer must not be smaller than 0.00129399 BTC.
- 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.
Bitcoin against OP Mainnet (Optimism)
| Bitcoin | OP Mainnet (Optimism) | |
|---|---|---|
| Network type | Layer one (L1) | L2, optimistic rollup |
| Fees are paid in | BTC | ETH |
| Fee level | ≈ $0.11 | ≈ < $0.0001 |
| Speed | slow | fast |
| Block | ~10 min | ~2 sec |
| Address shape | 1…, 3…, bc1… | 0x… |
| Memo or tag | not needed | not needed |
| Ethereum-style address (0x…) | no | yes |
| Official withdrawal to Ethereum | — | ≈ 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) | Usually a wrapper like WBTC, which then has to be swapped |
| 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 Bitcoin; 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 |

From 0.00129399 to 131 BTC per order. The lower limit is roughly $99.01.
Where does the 0.00129399 BTC floor come from?
Network fees and order handling eat a small transfer alive — below 0.00129399 BTC 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 BTC, and that one goes to the blockchain, not to us.
How long does BTC to ETH Optimism take?
The clock starts with confirmations: the order goes into work once Bitcoin confirms your transfer. After that it comes down to how busy the network is. A block in Bitcoin closes in about 10 min.

Which network will ETH Optimism arrive in?

Where is receiving ETH cheaper?
The cheapest is usually ETH Arbitrum, ETH BEP20, ETH Optimism. 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.
