  1. ETH: changing network from OP Mainnet (Optimism) to BNB Smart Chain

ETH: changing network from OP Mainnet (Optimism) to BNB Smart Chain

It is still ETH, only in a different blockchain: you send ETH Optimism, and the payout of ETH BEP20 goes to your address in BNB Smart Chain. Bridge contracts, signatures and wrapped tokens play no part.

Rate and amounts for ETH Optimism → ETH BEP20 1 ETH Optimism = 0.99999 ETH BEP20 1 ETH BEP20 = 1 ETH Optimism

Preliminary figure: the final amount is locked in the order.

Current maths: 0.99999 ETH BEP20 for every ETH Optimism, and 1 ETH Optimism per ETH BEP20 in reverse. Over 24 hours ETH Optimism/ETH BEP20 came in at about 0%. Over the week, about 0%.

The weekly range ran from 1 to 1 ETH BEP20, a spread of 0%. One order takes from 0.0374734 to 3,730 ETH Optimism. In dollars that is roughly $100.33.

The robot sends the payout in the BNB Smart Chain (BEP20) network, so the address has to belong to that network — a transfer to another one will not arrive.

Which network ETH arrives in

The same ETH goes out in several networks. Each has its own rate and its own floor, and the fee is charged by the network itself.

How the ETH Optimism → ETH BEP20 exchange runs

  1. Work out the amount in the calculator — orders start at 0.0374734 ETH Optimism.
  2. Give a ETH address on BNB Smart Chain (BEP20) and a contact for the order.
  3. Send ETH Optimism on Optimism, exactly the amount the order shows.
  4. Nothing else is needed from you: as soon as the network confirms the transfer, the robot sends Ethereum BEP20 to your address. The order page shows the status.

Swap ETH Optimism for ETH BEP20

Check this before sending ETH Optimism

  • The address network is BNB Smart Chain (BEP20). Sending through another network almost always means losing the transfer.
  • The transfer must not be smaller than 0.0374734 ETH Optimism.
  • Copy the address in full, then check its first and last characters once it is pasted.
  • Ethereum, Arbitrum, Optimism, BNB Smart Chain and Polygon addresses look the same (0x…) — make sure the wallet is switched to BNB Smart Chain.
  • Keep a reserve of BNB at the same address — without it ETH cannot be sent on later.
  • Send exactly the amount stated in the order: the automation matches your payment against it, and any difference sends the order back for recalculation.

Why people take the ETH Optimism → ETH BEP20 route

  • Changing networkETH from Optimism (fee ≈ < $0.0001) moves over to BNB Smart Chain (BEP20) (fee ≈ $0.0025). That is how people top up a wallet or an exchange that takes one network only.
  • It works both waysThe ETH BEP20 → ETH Optimism direction is open as well — going back into ETH takes the same route and the same automation.

Common questions: ETH Optimism → ETH BEP20

What rate does ETH Optimism to ETH BEP20 run at?
As of Sep 30, 2026 23:55 it is 1 ETH Optimism = 0.99999 ETH BEP20. The figure updates on its own, and the calculator always shows the current one. On the market that is around $2,677.36.
What amounts does ETH Optimism → ETH BEP20 accept?
From 0.0374734 to 3,730 ETH Optimism per order. The floor is roughly $100.33.
Why can I not swap less than 0.0374734 ETH Optimism?
The network fee and the handling do not depend on the amount. On a transfer below 0.0374734 ETH Optimism they eat a noticeable share of it, and the swap stops making sense for either side.
Is anything charged on top of the rate?
No. The payout is already worked out at the rate in the calculator. Separately you pay only the network fee for sending ETH Optimism, and the blockchain takes that one.
How long does swapping ETH Optimism for ETH BEP20 take?
The clock starts with confirmations: as soon as Optimism confirms your transfer, the order goes out for payout with no operator involved. After that the timing is set by how busy the network is — which is the difference between quick and instant. A block in Optimism closes in about 2 sec.
Will real ETH be credited, or a wrapper?
ETH BEP20 is the ordinary ETH token of the BNB Smart Chain network: exactly the same one an exchange sends when you withdraw into this blockchain.
Is BNB needed to receive ETH BEP20?
Not to receive. BNB comes in handy later, when you decide to move ETH from your address.
Which network will ETH BEP20 arrive in?
The payout goes out on BNB Smart Chain (BEP20). Check that the receiving wallet supports that network.
Which network is cheaper for receiving ETH?
Usually ETH BEP20, ETH Arbitrum works out cheaper. Still, the network is picked by what the recipient accepts, not by the fee.
What happens if the rate moves while I am paying?
Nothing: the rate is locked in the order and holds for as long as the order is alive. It is recalculated only if the payment arrives late or for a different amount — so send the exact sum, and send it promptly.
What did the ETH Optimism to ETH BEP20 rate do over the month?
Over the month, about 0%: a low of 1, a high of 1, an average of 1 ETH BEP20 per 1 ETH Optimism.
Can I swap back, ETH BEP20 for ETH Optimism?
Yes, the reverse is open too: 1 ETH BEP20 = 0.99999 ETH Optimism. The link to switch sits under the calculator.
