Exchange Optimism to Ethereum (Base)

Move Optimism (OP) into Ethereum (Base) (ETH) on Base mainnet through TunnelSwap — a privacy-first, anonymous no-KYC swap. You send OP from your own wallet; ETH arrives at the payout address you paste. Top rates and low fees show before you broadcast, and most routes finish within minutes after deposit confirmations.

Tunnel in 3 steps

  1. Choose how much OP to send and paste the Ethereum (Base) address that should receive funds on Base mainnet.

  2. Open the order to freeze the quote and reveal a one-time deposit destination.

  3. Broadcast OP to that destination. Once confirmations clear, ETH is pushed to your payout wallet.

Before you broadcast

  • Optimism confirmations are usually fast — often within a minute.
  • Send OP on Optimism mainnet only — not Ethereum, Base, or Arbitrum unless your order says otherwise.
  • Use an Optimism-compatible wallet and address (0x…). Leave enough ETH on Optimism for gas if sending ERC-20 tokens.
  • Still waiting on ETH? Give the wallet a few minutes to sync, then share your Exchange ID with support if the order already lists a payout hash.

Base ETH payout tips

  • Payouts go to Base — verify your wallet network is Base (chain ID 8453).
