⇄ Reverse exchange ETH BEP20 → ETH OptimismThe ETH Optimism → ETH BEP20 bridge runs at 1 ETH Optimism = 0.9999 ETH BEP20. For 100 ETH Optimism you receive 99.99 ETH BEP20; the amount is calculated by this rate, and you only pay the OP Mainnet (Optimism) fee for your own transfer. You can bridge from 0.08616 ETH Optimism. That is about $211.49.
OP Mainnet (Optimism) is an Ethereum layer-2 rollup; BNB Smart Chain is a layer-1 blockchain. Fees on BNB Smart Chain are paid in BNB: to move ETH further, keep a little BNB on the same address.
OP Mainnet (Optimism) vs BNB Smart Chain: network comparison
| OP Mainnet (Optimism) | BNB Smart Chain | |
|---|---|---|
| Network type | Layer 2 (optimistic rollup) | Layer 1 |
| Fees are paid in | ETH | BNB |
| Fee level | low | low |
| Speed | fast | fast |
| Block time | ~2 sec | — |
| Address format | 0x… | 0x… |
| Memo / tag | not needed | not needed |
| EVM-compatible addresses (0x…) | yes | yes |
| Withdrawal to Ethereum via the official bridge | ~7 days (challenge period) | — |
Fee and speed levels are relative and depend on network load.
Crystal-Trade or a classic bridge: what is the difference
| Crystal-Trade | Classic bridge | |
|---|---|---|
| What you receive | ETH on BNB Smart Chain | Depends on the bridge: on some networks it is a bridged version of the token |
| Wallet connection and approvals | Not needed: you send coins to the order address | Needed: you connect a wallet and sign contract transactions |
| Coins for fees on BNB Smart Chain | Not needed to receive | Often needed to claim funds or move them after the bridge |
| Time | After the OP Mainnet (Optimism) confirmations; the status is shown on the order page | Depends on the bridge and the load of both networks |
| Who holds the funds during the transfer | Crystal-Trade, for the duration of the order (with an AML check) | The bridge smart contract or its validators |

How to bridge ETH Optimism from OP Mainnet (Optimism) to BNB Smart Chain
- Enter the ETH Optimism amount in the calculator (from 0.08616 ETH Optimism) and open the exchange form.
- Paste your BNB Smart Chain address (0x…) to receive ETH BEP20.
- Send ETH Optimism over the OP Mainnet (Optimism) network to the address from the order, exactly in the amount shown.
- After the OP Mainnet (Optimism) confirmations, ETH BEP20 is sent to your BNB Smart Chain address. The status is shown on the order page.
Before you bridge ETH Optimism to BNB Smart Chain
- The receiving address must be on the BNB Smart Chain network (0x…).
- Addresses on Ethereum, Arbitrum, Optimism, BNB Smart Chain and Polygon look the same (0x…): make sure the wallet shows BNB Smart Chain as the network.
- Send ETH Optimism over OP Mainnet (Optimism) only — a transfer over another network will not reach the order.
- The amount sent must be at least 0.08616 ETH Optimism.
- To move ETH on BNB Smart Chain later, you will need a little BNB on the same address.
- Funds go through an AML check; high-risk transfers may be held until the check is complete.
ETH Optimism → ETH BEP20 bridge: FAQ
What does the ETH Optimism → ETH BEP20 bridge do?
It is a transfer of ETH from OP Mainnet (Optimism) to BNB Smart Chain. On Crystal-Trade it works as an exchange order: you send ETH Optimism and receive ETH BEP20 at your BNB Smart Chain address, without bridge contracts.
How long does it take to bridge ETH Optimism to BNB Smart Chain?
The order is processed after the OP Mainnet (Optimism) network confirms your transfer, then ETH BEP20 is sent over BNB Smart Chain. A new OP Mainnet (Optimism) block appears about every 2 sec.
Will I receive native ETH or a wrapped token?
ETH BEP20 is the standard ETH token on BNB Smart Chain — the same one exchanges send when you withdraw to this network.
Do I need BNB to receive ETH BEP20?
Not to receive. You will need BNB later to send ETH from your BNB Smart Chain address.
Which address should I enter to receive ETH BEP20?
An address on the BNB Smart Chain network: 0x… An Ethereum-style address (0x…) works, but the wallet must be set to BNB Smart Chain.
What are the minimum and maximum amounts for ETH Optimism to ETH BEP20?
The minimum is 0.08616 ETH Optimism and the maximum is 4,070 ETH Optimism.
Are there extra fees when exchanging ETH Optimism to ETH BEP20?
The amount you get is calculated at the exchange rate shown in the calculator. The network fee for sending ETH Optimism is paid by the sender and depends on the wallet and network load.
Can I bridge back from BNB Smart Chain to OP Mainnet (Optimism)?
Yes, the reverse bridge ETH BEP20 → ETH Optimism is available: 1 ETH BEP20 = 0.9999 ETH Optimism.
Do I need to register to exchange ETH Optimism to ETH BEP20?
No, you only need to enter the receiving details and contact information in the order.
