Exchange in 3 steps
-
Choose how much OP to send and enter your Ethereum address on Ethereum mainnet.
-
Hit Exchange to open your order page with the live rate and deposit details.
-
Transfer OP to the address on your order — after confirmations, ETH is sent to your wallet automatically.
What do you need to know?
- 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.
- ETH not visible yet? Wait a few minutes, resync your wallet, then contact support with your order ID if the payout tx is already listed.
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.
Ethereum — programmable money on-chain
ETH powers Ethereum mainnet — gas, staking, DeFi, and most smart-contract activity in crypto live here.
What if my ETH hasn't arrived?
Check the order page for a payout transaction hash first.
Confirm your wallet is on Ethereum mainnet and fully synced.
How fast is the ETH payout?
Most payouts land within minutes once your deposit confirms — Ethereum blocks are ~12 seconds apart.
Receiving ETH on the correct network
- Payouts go to Ethereum mainnet — not BSC, Base, Arbitrum, or other L2s unless your order explicitly lists them.
- Double-check the address you paste: one wrong character sends funds to an unreachable wallet.
- Self-custody wallets (MetaMask, Rabby, hardware devices) are recommended for long-term holding.
Float vs fixed rate on ETH payouts
The rate mode you pick at the top of the swap widget affects how your final ETH amount is calculated.
- Float rate follows the market until your deposit confirms — best when mempools are quiet.
- Fixed rate locks the quote for a short window — useful when ETH price is moving quickly.

Frequently asked questions
Do I need KYC to swap OP to ETH?
No. SendSwap is a non-custodial instant exchange — no account, no ID checks, and no KYC for Optimism to Ethereum swaps.
How long does OP to ETH take?
Most swaps finish in 1–5 minutes. Timing depends on Optimism mainnet and Ethereum mainnet confirmations and current network load.
Is OP to ETH non-custodial?
Yes. You send OP from your wallet and receive ETH directly to the address you provide — SendSwap never holds your keys.
What if I send OP on the wrong network?
Always match the network on your order page (Optimism mainnet for deposits). Wrong-network sends may not be credited — read our swap safety guides before you send.
