⇄ Reverse exchange ETH Arbitrum → ETH Optimism

The ETH Optimism → ETH Arbitrum bridge runs at 1 ETH Optimism = 0.9999 ETH Arbitrum. For 100 ETH Optimism you receive 99.99 ETH Arbitrum; 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.

On Arbitrum One fees are paid in ETH, so the ETH Arbitrum you receive can be used right away.

Exchange ETH Optimism to ETH Arbitrum

Before you bridge ETH Optimism to Arbitrum One

  • The receiving address must be on the Arbitrum One network (0x…).
  • Addresses on Ethereum, Arbitrum, Optimism, BNB Smart Chain and Polygon look the same (0x…): make sure the wallet shows Arbitrum One 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.
  • Funds go through an AML check; high-risk transfers may be held until the check is complete.
