Who takes the OPEN → ETH BASE route
- Fuel for BASEWithout Ethereum nothing moves in BASE — every transfer and every contract call is paid in it.
- Different basketsDaily moves of OPEN and ETH over 90 days line up at 0.41 (they travel alike) — the looser the link, the less a portfolio depends on one coin.
- A road both waysThe ETH BASE → OPEN direction is open too, so going back into OPEN takes the same route.

How the OPEN → ETH BASE order runs
- Work out the amount in the calculator and press the exchange button.
- Enter a ETH address in BASE and a way to reach you.
- Send OPEN in OpenLedger 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 OPEN
- The address network is BASE. Sending through another network usually means losing the transfer.
- 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.

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 OPEN, and that one goes to the blockchain, not to us.
How long does OPEN to ETH BASE take?
The clock starts with confirmations: the order goes into work once OpenLedger confirms your transfer. After that it comes down to how busy the network is.
Which network will ETH BASE arrive in?
The payout leaves in BASE. Make sure the receiving wallet works with that network.
Where is receiving ETH cheaper?
The cheapest is usually ETH BEP20, ETH Arbitrum, 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.
