How the swap works
-
Type the OP amount and paste your Ethereum (Base) payout address on Base mainnet.
-
Press Exchange to open the live quote and the deposit address for this order.
-
Broadcast OP to that deposit. After the required confirmations, ETH is sent to your wallet.
Check these before you send
- 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.
- If ETH has not appeared yet, wait a few minutes and refresh the wallet. When the order already shows a payout tx, contact support with your order ID.
Optimism — Ethereum L2 with low fees
OP is the governance token of Optimism — an Ethereum rollup with fast, low-cost transfers and deep Superchain liquidity.
OP on Optimism mainnet
Use an Optimism wallet for deposits. L1 Ethereum or other L2 sends may not be credited.
Leave enough ETH on Optimism for gas when moving OP or other tokens.
ETH on Base — Coinbase L2
Native ETH on Base — Ethereum's value on Coinbase's L2 with low fees, fast finality, and growing on-chain activity.
Base ETH not received?
Confirm your wallet is on Base mainnet and fully synced — not Ethereum L1.
Base ETH payout tips
- Payouts go to Base — verify your wallet network is Base (chain ID 8453).
- Check Basescan with the payout tx hash from your order page.
- Bridging to Ethereum L1 is a separate step after you receive ETH on Base.

Frequently asked questions
Does OP to ETH require KYC or an account?
No. PeakSwap does not ask for a profile, ID documents, or a hosted balance for Optimism to Ethereum (Base).
How long until ETH arrives?
Many orders finish in a few minutes. Optimism mainnet deposit confirmations and Base mainnet payout time set the wait.
Do you hold OP or ETH for me?
No. You send OP from a wallet you control and ETH is paid to the address you provide — PeakSwap does not keep a user wallet.
What if I send OP on the wrong chain?
Use Optimism mainnet exactly as shown on the order. A wrong-network send may not be credited — read the swap safety notes first.
