⇄ Reverse exchange ETH Optimism → ETH BEP20The ETH BEP20 → ETH Optimism bridge runs at 1 ETH BEP20 = 0.9999 ETH Optimism. For 100 ETH BEP20 you receive 99.99 ETH Optimism; the amount is calculated by this rate, and you only pay the BNB Smart Chain fee for your own transfer. You can bridge from 0.08616 ETH BEP20. That is about $211.49.
BNB Smart Chain is a layer-1 blockchain; OP Mainnet (Optimism) is an Ethereum layer-2 rollup. On OP Mainnet (Optimism) fees are paid in ETH, so the ETH Optimism you receive can be used right away.
BNB Smart Chain vs OP Mainnet (Optimism): network comparison
| BNB Smart Chain | OP Mainnet (Optimism) | |
|---|---|---|
| Network type | Layer 1 | Layer 2 (optimistic rollup) |
| Fees are paid in | BNB | ETH |
| Fee level | low | low |
| Speed | fast | fast |
| Block time | — | ~2 sec |

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 | native ETH on OP Mainnet (Optimism) | 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 OP Mainnet (Optimism) | Not needed to receive | Often needed to claim funds or move them after the bridge |
| Time | After the BNB Smart Chain 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 BEP20 from BNB Smart Chain to OP Mainnet (Optimism)
- Enter the ETH BEP20 amount in the calculator (from 0.08616 ETH BEP20) and open the exchange form.
- Paste your OP Mainnet (Optimism) address (0x…) to receive ETH Optimism.
- Send ETH BEP20 over the BNB Smart Chain network to the address from the order, exactly in the amount shown.
- After the BNB Smart Chain confirmations, ETH Optimism is sent to your OP Mainnet (Optimism) address. The status is shown on the order page.
Before you bridge ETH BEP20 to OP Mainnet (Optimism)
- The receiving address must be on the OP Mainnet (Optimism) network (0x…).
- Addresses on Ethereum, Arbitrum, Optimism, BNB Smart Chain and Polygon look the same (0x…): make sure the wallet shows OP Mainnet (Optimism) as the network.
- Send ETH BEP20 over BNB Smart Chain only — a transfer over another network will not reach the order.
- The amount sent must be at least 0.08616 ETH BEP20.
- Funds go through an AML check; high-risk transfers may be held until the check is complete.
