Three steps on ToSwap
-
Set the OP amount and paste the Ethereum (Base) address that should collect payout on Base mainnet.
-
Tap Exchange to lock the live ToSwap quote and reveal this order’s deposit details.
-
Send exactly that OP amount to the deposit. After Optimism mainnet confirms, ETH is pushed to your 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.
- If ETH is late, refresh your wallet and re-check the order status. When a payout hash is already listed, email or SimpleX support with your Exchange ID — ToSwap has no login that can reopen expired pages.
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.
Deposit checklist
Chain mismatches and bad addresses are the usual failure modes — skim these notes before you fund the deposit.

FAQ for this route
Is KYC or a ToSwap account required for OP → ETH?
No. ToSwap never opens a profile or asks for ID documents on a standard Optimism to Ethereum (Base) order. You stay non-custodial on both legs.
How fast does ETH usually arrive?
Many payouts leave within minutes after the Optimism mainnet deposit confirms. Congestion on Optimism mainnet or Base mainnet can stretch that — fees and mempools set the clock, not a manual review.
Does ToSwap hold my OP or ETH?
No hosted balance. You broadcast OP from a wallet you control; ETH is paid only to the address you paste. Nothing sits under a ToSwap username.
What if I send OP on the wrong network?
Match Optimism mainnet exactly as printed on the order badge. A wrong-chain deposit often cannot be credited automatically — double-check before you broadcast.
