Exchange in 3 steps
-
Choose how much ETH to send and enter your Optimism address on Optimism mainnet.
-
Hit Exchange to open your order page with the live rate and deposit details.
-
Transfer ETH to the address on your order — after confirmations, OP is sent to your wallet automatically.
What do you need to know?
- Ethereum deposits confirm quickly — usually within a few blocks (~12s each).
- During gas spikes, confirmation cost rises but inclusion remains fast.
- Send ETH on Ethereum mainnet only — not BSC, Base, or other L2s unless your order says otherwise.
- OP not visible yet? Wait a few minutes, resync your wallet, then contact support with your order ID if the payout tx is already listed.
Ethereum — programmable money on-chain
ETH powers Ethereum mainnet — gas, staking, DeFi, and most smart-contract activity in crypto live here.
Sending ETH to the right network
Use an Ethereum mainnet wallet for deposits. L2 or alternate-chain sends may not be credited.
Leave enough ETH in your wallet to cover gas on top of the swap amount.
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 not received?
Confirm your wallet is on Optimism mainnet and fully synced.
OP payout tips
- Payouts go to Optimism — verify your wallet RPC is set to Optimism, not Ethereum mainnet.
- Check Optimistic Etherscan with the payout tx hash from your order page.
- Allow a minute for your wallet to refresh after the explorer shows the transfer.

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