Ethereum and Optimism live on different blockchains, and this swap uses the native assets on both, with no bridge contract and no wrapped token. The exchange receives ETH on Arbitrum One and pays out OP on OP Mainnet.
Your OP is paid on OP Mainnet. Use an address that starts with 0x and is 42 characters long.
Type how much ETH you want to swap (minimum about 0.00182 ETH). The OP you will receive updates live.
The top no-KYC offer is preselected. Open 'All offers' to compare fixed and floating rates, speed and each exchange's KYC rating.
Paste the OP Mainnet address where you want to be paid. A refund address for your ETH is optional but recommended.
Send the exact amount to the deposit address on Arbitrum One. After it confirms (about a minute), the OP is sent to your address.

Enter the ETH amount on this page, choose an offer, paste your OP address and send your ETH to the deposit address shown. AltoSwap has no accounts and asks for no identity documents, and by default it only shows exchanges rated A for KYC, meaning providers that do not run identity checks. The OP is paid directly to your wallet.
The rate moves with the market every few seconds and depends on the amount. The calculator at the top of this page requests live quotes from 20+ exchanges and shows the best current ETH to OP rate for the amount you enter.
The minimum is about 0.00182 ETH and the maximum about 569 ETH. Limits vary slightly between exchanges and follow market prices; the form tells you immediately if your amount is outside the range.
Usually 5 to 30 minutes. Most of that is waiting for your ETH deposit to confirm on Arbitrum One, which takes about a minute. There is no verification step, so nothing else adds to the wait.
AltoSwap does not know who you are (no account, no email, no identity checks) and the default route uses no-KYC exchanges. Both Arbitrum One and OP Mainnet are public ledgers, though, so the transactions themselves are visible on-chain. For on-chain privacy, swap into a privacy coin such as Monero.
Your OP is paid on OP Mainnet. Use an address that starts with 0x and is 42 characters long. Always use an address in a wallet you control and double-check the first and last characters before sending.
Everything. The exchange's spread, the OP Mainnet network fee for the payout and any service commission are already inside the quoted rate, so the amount shown is what you receive: exactly on a fixed rate, approximately on a floating rate. You only pay your own Arbitrum One network fee to send the deposit.
Yes. The reverse direction, OP to ETH (Arbitrum), works the same way and has its own page and live rate on AltoSwap. Each direction is quoted independently, so the two rates are not exact mirrors of each other.
